Monitor blanks off during boot up.

After zapping the PRAM on my G4 (AGP, Ati rage 128 pro) my monitor now blanks off just after the Apple logo in the boot up sequence. The monitor is a Hewlett Packard HPw19 flat screen. In this blank state the monitor shows the message "Attention - Input Not Supported". I'm guessing that zapping the PRAM has switched OS X into a screen resolution that the monitor can't handle. SO....my problem is... how can i switch screen resolution of the video card etc when i cannot use the display? :-/
thanks for any help/ideas

I eventually fixed this by installing a fresh system to the 2nd harddisk - this system booted fine so i could then switch screen resolution and boot from the original system again. Had i had a spare monitor i could have booted from that, switched screen resolution, then plugged in the original monitor. I think it must be an issue with the HP w19 not being 100% ok with OS X.

Aspire One D255 monitor shuts off during boot

Every time I boot, immediately after the kernel lauches init, my screen powers off. About 15 seconds later, it comes back on.
The delay before coming back on seems to be independent of the init process. If I speed init up, by the time it comes back on it's waiting at the login prompt. If I slow it down, it comes back on while init is still running.
I tried adding an echo -e -n '\033[13]' to my init scripts in an effort to unblank the display, but it doesn't help.
This happens both booting of the install image and after installation. It makes it extremely hard to figure out what's going on during startup.
Has anyone seen this before?

I have a similar issue with my aspire one, but the display is not turning off, it is actually the backlight turning off during boot. I use fbsplash with a dark theme but a bright progress bar. During boot, it appears as if the screen has turned off, but looking closely, I can still see the progress bar.
I have tried several different methods of keeping the backlight on to no avail.
Personally I am thinking it is monitor signal detection during a monitor mode reset during boot, ie from console resolution switching to KMS resolution. Most monitors lose signal detection when changing mode (in my experience). Some display a "No Signal" message of some sort, some briefly turn off until signal is detected again, and in the Aspire One case, the backlight turns off. Put it down to monitor manufacturers built in power saving "features".
Tha same thing happens when I boot windows.
Of course, if anyone does come up with a solution, I am eagerly listening!
Cheers.

[SOLVED] USB Harddrive via fstab turned off during Boot - Error

Hello^^
I'm trying to mount my external USB Drive.
I put the following line in fstab:
/dev/sdb1 /media/Musik ext4 noauto,user,default 0 1
I only want to start the Harddive occasionally.
The problem is, when the drive is completly turned off during boot I get the following error:
No such file or directory while trying to open /dev/sdb1
Possibly non existend device?
I thought that the noauto Option should prevent fstab from mounting the hdd???

Let me give you a hand then. The following I have in my /etc/udev/rules.d/11-media-by-label-auto-mount.rules, and what it does is:
-- pick the name of a drive,
-- create a dedicated /media/mountpoint name (certainly, "mountpoint" is replaced by the name of your drive),
-- mount the drive on boot,
-- unmount the drive on shutdown and delete the /media/mountpoint.
KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"
# Import FS infos
IMPORT{program}="/sbin/blkid -o udev -p %N"
# Get a label if present, otherwise specify one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"
# Global mount options
ACTION=="add", ENV{mount_options}="relatime"
# Filesystem-specific mount options
ACTION=="add", ENV{ID_FS_TYPE}=="vfat|ntfs", ENV{mount_options}="$env{mount_options},utf8,gid=100,umask=002"
# Mount the device
ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}"
# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}"
# Exit
LABEL="media_by_label_auto_mount_end"
Plenty of handy examples you can find in /lib/udev/rules.d/ and modify them so they meet you needs. I hope it clarifies the matter a bit.

RV180 (wired only) problems with firmware 1.0.4.14, fails to boot correctly + LAN ports power off during boot (downgrading to 1.0.3.10 = fine again).

Hi All,
A few months ago when 1.0.4.14 was released I was quick to update to this version from 1.0.3.10 but very quickly ran into issues.
Bit of background info... I am not doing anything complex with this box, basic IP4 network over all LAN ports, no VLANs, firewall enabled and allowing 2 port access rules to a static IP address. Any static IPs are assigned manual at host level but all other devices receive DHCP IP addresses. I don’t host VPN on this RV180 but I do with another. Routing VPN has no issues. WAN is connected to another switch provided by my ISP who provides DHCP IP Address with their DNS etc. Only LAN ports 1 and 2 are connected, port 1 to my Wireless AP (AP mode passing all requests to the RV180, DHCP etc.), port 2 connects to a 8 port Smart Switch (but all 'Smart' features are currently not in use, so basic switching only). All other settings on the RV180 are on recommended defaults.
Everything is working fine on 1.0.3.10 but I have all kinds of issues after updating to 1.0.4.14. Here are the actions and experiences I had...
1) Backup my RV180 config to txt file.
2) Navigate to the firmware upgrade page and follow steps to complete the upgrade process from 1.0.3.10 to 1.0.4.14. *router does the normal process of upgrading*
3) RV180 reboots to complete but doesn’t come back up even after waiting 5-10 mins. LAN ports enable during boot up (link lights on) but after about 2mins turn off (no link lights). WAN light is on alongside the Power Light.
4) Power cycle even with rest... Same results.
5) Reset the RV180 to default settings. I can sometimes get the unit to boot up and the LAN remains active and powered up. The web UI is VERY slow compared with 1.0.3.10. Internet sometimes works and sometimes doesn't (I would expect it all work without issue on default settings).
6) I repeat this a few times, various resets, powered off waiting periods, etc. but I always have issues. I did manage to get some log file information and the Kernel appears in the Alert, Error and also the Warning logs (please see attached files).
7) I gave up at this point. No major issues like this reported on the internet from a few google searches etc. So I then reset to defaults (1.0.4.14), downgrade to 1.0.3.10 and finally reset to defaults again + restore backup config settings (with some manual changes).
The router has remained like this and seem to be working fine, but I would like any security improvements from 1.0.4.14 firmware on my device.
Anyone able to help, have the same issue or can advise me in any other ways?
I see 1.0.3.10 isn’t displayed as a firmware download on the standard support page for the RV180 now. Only 1.0.2.6 and 1.0.4.14. Do I need to downgrade again to 1.0.2.6 before upgrading to the latest version?
Regards,
~FAZ~

Hi,
I recently bought a RV180 router and immediately I encountered the same problem; practically I am not able to access the web GUI.
The PC is directly connected to the router, nothing else is connected; the TCP/IP configuration is as follows:
PC: 192.168.1.100
RV180: 192.168.1.1
GATEWAY: 192.168.1.1
SUBNET MASK: 255.255.255.0
Once the router is turned on, the power LED flashes fastly, the Ethernet LED is on but after few minutes it disappears and the PC detects a disconnection of the Ethernet cable.
The router is not pingable and, as I said, the web interface is not reachable.
I have tried to power cycle the router, to reset it (pressing the reset button for more than 3 second and for more than one minute), to access the rescue mode and download a new firmware through TFTP, but nothing worked.
Few times, after many boot and reset trials,I was able to access the web interface and in one of these occasions I updated the firmware to 1.0.4.14 but once the router is powered off the problem arises again at the next power on.
I have not tried yet to downgrade to an older firmware version.
Can you suggest any solution? thank you.

Build-in webcam issue: how to turn it off during boot-up?

Hi,
I have a laptop - Asus K52J & x86_64 - with a built-in webcam. During boot-up, the webcam turns on in - rough guess - 50% of the time. I don't find any obvious pattern when/why the webcam turns on.
Searching this forum/internet doesn't give me a good answer...
1/ I prefer a solution where the webcam is turned off on boot and where I can turn it on when necessary.
2/ I can afford to disable the webcam when running linux.
3/ Disabling in BIOS (often given solution) is not an option.
For 1/, the only solution I got was running following and closing mplayer window. This turns off the webcam, but this is not an efficient manner. Is there another software-based work-around?
mplayer tv:// -tv driver=v4l2:device=/dev/video0
For 2/ I hear blacklisting the module is the solution. But how do I find the correct module?
lsmod
gives a whole list (pastebin).
Is it videodev and/or v4l2_compat_ioctl32? How can I be sure? Any advice on this for other users with other laptops?
Thanks for any help on advance!
Kind regards,
davidbe

Your webcam uses the uvcvideo module so blacklist that one in /etc/rc.conf.

Macbook Pro Lion shuts off during boot up

I have a 13" MacBook Pro purchased in 2011. I had the internet lock up on me and hard shut down the computer. Now when I press the power button, the machine begins to boot up and the apple pops up then the progress bar pops up and the wheels starts to spin, but the machine shuts down about 5 seconds into it.
I have seen this problem on older posts (pre-Lion) and one solution was to hold option during start-up and then boot off th esystem restore disc, but Lion is all internet based, so no disc here. When I do that, it pops the option to select an internet source, which I do, then the HD symbol pops up with an arrow below it. When I clikc the arrow (which is the only apparent option) it does the same thing and shhuts off at the same point.
HELP!

Try booting with command-R. This will boot into the repair parttion. From here you can run disk utility and other programs. You can also do a repair installation of Lion which will almost certainly solve the problem. Doing so shouldn't wipe out your user data, but installing OS updates will be required.

Monitor Blanks Out During Any Directx9.0 Games

Hello there! Here's my problem, at random times during games, (most often games using directx 9.0 cause this) my monitor will go blank, display a no signal screen and will not be able to be turned back on. However the sound continues for a little bit and then stops. The problem is not the monitor, as I have tried it with another monitor which narrows it down to the video card. As indicated in my specs my Vcard is a Geforce 4 Ti4200 64mg. There isn't really a consistent time frame in which the errors occur, it could be anywhere from 5 minutes of playing to 5 hours. I have tried every possible version of drivers (after uninstalling previous of course)and yet the problem still crops up. You are my last hope!!! Thanks In Advance.

Hi,
Try increasing the AGP Aperture size in bios to 128........
It sounds like the card is running out of TEXTURE memory........

Satellite M200 monitor turns Off after boot & battery won't charge

Hello, I'm from Jakarta, Indonesia
I have a problem with my Toshiba Satellite M200 Notebook (Running Windows 7 Home Premium)
after i press the power button to power up my notebook, It works fine showing BIOS and Windows Boot Screen,
but after that my monitor just suddenly turn off when Windows supposed to show login screen.
sometimes the monitor don't turn off, but shows lower resolution (i don't know exactly what resolution, maybe 1024x768 or 800x600, i'm using 1280x800)
so the only thing i can do is press the power button again to shutdown improperly then press the power again to power up, my monitor works normally
try to shutdown then power up again in couple hours later, the problems comes again.
from the moment i install Windows 7, i use 8.15.10.1930 driver version (downloaded from Intel Download Center, which included Intel TV Wizard)
2 days ago my friend said that i should install the driver from Toshiba's support site, so i went to csd.toshiba.com and download the 8.15.10.1825 version from that site (which not included Intel TV Wizard )
my monitor works normally after I installed the driver i've got from csd.toshiba.com, so i think that the problem because Intel TV Wizard somehow messed up with my notebook. But this morning this problem comes again, my monitor just turns off suddenly ..
besides this problem my battery seems like failed to recharge, Windows shows my battery has fully charged, but when i plugged out my AC adapter,
it just remains for 15-20 minutes before my notebook shut down automatically
three months ago i just brought my notebook to local Toshiba Service Center and bought new motherboard to replace my old mobo (which have a VGA issue too!)
there's something i can do (related to Windows or software/driver) or i have to bring my notebook to the service center again?
are they somehow make a wrong wiring when replacing my motherboard?
and am i have to replace my battery pack too?
i've been using this notebook for about a year and half and there's nothing wrong with my battery before replacing the motherboard
any help would be appreciated :D

well, i can't find my model's driver in Toshiba Europe site,
in Satellite M series it only shows M100 and M70 and not including M200
i found http://pc.toshiba-asia.com which covering my region. after choosing my product they give me link to download Windows 7 driver, here's the link
http://support.toshiba-tie.co.jp/windows7/download/Satellite_M200_32_sp.htm
Windows7 Driver | Intel Display Driver | 8.15.10.1825
they have the same driver version (and same size too) with my current driver i've got from csd.toshiba.com
any other ideas besides the driver issue ?

LG 34um95 Ultrawide Monitor Not Waking During Boot on 2013 MP

I have a new LG 34um95 ultra-wide monitor that is Mac Pro comparable and has thunderbolt ports. When try to boot on my 2013 Mac Pro using bootcamp and switch between OSX and Windows 8, the monitor is black (both HDMI and on thunderbolt) as if the monitor is not recognized. If I hook up a DVI to MiniDV port to an old school monitor I get a display on that just fine. Anytime I load OSX, the LG monitor is black until the login page - I cannot see the white screen with the apple logo ever except for the old DVI monitor.
I also get random flashes and stutters on the picture of the LG monitor?
I don't know if it's the monitor or the Mac Pro? Already called apple care and they told me to reset the VRam. That did nothing.
Any Help?

Hi,
I have the same issue with this monitor using Thunderbolt on my Late 2013 6-core Mac Pro with D500 GPUs. I get no image displayed until I get past my FileVault login and it takes me to the desktop. I have to enter my password blind as nothing is displayed at all during the boot. This also prevents me from choosing boot drives, or allowing other users to unlock the FileVault. The issue also occurs during a safe boot, and booting into recovery mode. My Mac Pro is running Yosemite, however it hasn't fixed the issue. I have tried a PRAM and SMC reset, however it hasn't changed the issue over Thunderbolt.
I have contacted LG (which is of no use as their support is really terrible), and Apple who actually sent my issue to engineering. However, engineering was only able to assist me with getting the HDMI working again. To get HDMI working, they had me do a PRAM reset with it plugged in using HDMI. They were unable to get the Thunderbolt working though, as the monitor is not officially supported.
I have been unable to find anyway to make the Thunderbolt work correctly on this monitor. This is very disappointing as this monitor is advertised by LG as being supported by the new Mac Pro.

Monitor turns off after boot? macmini

I have a strange display issue.
I am running a dual monitor setup on my 2010 mac mini. It used to work fine but now suddenly the monitor using the minidisplayport won't work right. It just stays turned off.
If I unplug the HDMI monitor and only use the minidisplayport, the connected monitor turns on while the computer boots (grey apple screen), but instead of eventually showing my desktop the monitor just turns off. The computer acts as if nothing is wrong. If i switch the monitor to the hdmi everything looks normal.
Resetting pram makes no difference.
Starting in safemode makes no difference. no picture.
Apple hardware test shows no issue. (The weird thing is, AHT has no problem keeping the minidisplayport -monitor running)

Only the Hdmi monitor shows in systems pref/displays. Ofcause i dont know if anything is going on on the black screen. There is no arrange displays option though.
I only have bad experience contacting apple, so that will be my last option. I have no apple store near by. The mini is still under waranty, but i also think/hope it is just a software issue.

MBP turns off during boot

Hello!
My mid-2010 MBP is having some issues. It is no longer under applecare. Last year, when it was still under applecare, I had a problem of the display going black many times per day while doing even simple tasks. I believe they replaced the logic board and everything worked just fine after that.
However, last night my laptop suddenly went black while viewing a PDF. I tried opening and closing the cover, nothing could get the screen back. At that time, the keyboard was still lit up and the caps lock button still worked (light would turn on and off when pressing).
I did a hard-reset.
The laptop screen lit up like it was starting, and then died. Tried again, nothing. So, I waited about five minutes and tried again. The screen lit up, the apple appeared, and then the laptop died.
After many attempts, I have seen it do many different things. Sometimes it dies before the apple appears. Sometimes it dies after that, but before login screen. Sometimes it dies on the login screen. Usually the longer I wait, the further it will go - however, even when stone cold and not warm at all after waiting hours, it will still only run for ten minutes before it turns off. Sometimes if I can get all the way through startup, it will run for a minute, or five minutes, or ten minutes, but it always fails. Sometimes it turns completely off, but sometimes only the display goes black and the keyboard stays lit. I can even change the keyboard illumination up or down when this happens. Its about a 50/50 chance whether the display will die or the whole laptop will die. Whichever one it is, though, it still requires 10-15 minutes before I can try again, or the machine will just fail halfway through startup.
I have also tried starting into bootcamp. It worked for five minutes in Windows and then died.
I have tried booting up while holding shift, but it was taking a very long time for the progress bar at the bottom to fill, and halfway through the laptop shut down.
As I said at the beginning, the logic board is one year old.

After sitting for a day, I started up the laptop and made it all the way through login. I let the machine sit without touching anything for about twenty minutes, nothing happened.
I then opened Chrome, and as soon as I began typing into the search box, the entire computer shut down, and restarted by itself.
Halfway through restart, the screen turned black. I waited, and after a minute the keyboard lit up so I knew it was at the login screen, though I couldn't see anything. I typed the first letter of my name, pressed enter, typed my password, and pressed enter again.
I presume the computer is logged in and sitting at the desktop now...I have the laptop set up so that if I move the cursor to one corner, it puts the display to sleep. When I do this with the track pad, I can see the keyboard lights dim, then light back up again when I move the cursor back out of the corner.
Anyone have any suggestions? How can I get my screen back?

MacBook Pro turns off during boot?

This is kind of a long story.
I have a 13-inch, Mid-2010 MacBook Pro running OS X Mavericks. I was using it near a bathtub, when a moderate amount of water spilled onto the keyboard. I immediately dabbed out most of it, and put it upside down for some time. It was running then, with all the keys and trackpad working fine. t turned it off, and tired turning it on after half an hour. Nothing. I decided to keep it switched off for 7 days, during which I would open the lid every now and then to find vapor on the screen from the keyboard which I would wipe and close again. I turned it on when there was no vapor spotted for 3 days. I plugged it in after 7 days, to see that the battery status indicator was erratic. It turned on with a sound from the SuperDrive (the usual click). There was no startup chime. A few minutes later, it turned off. I decided to reset the PRAM and SMC, and I realized that I can get to my account window successfully (and type a 22 letter password) as long as I keep any key pressed throughout bootup (option, command key, etc). I have tried many times, but it just turns off with a "nik" sound. I haven't backed up, and I have about 270 GB of important data stored that I CANNOT lose.
If it helps, it's 250GB drive crashed in December but it was replaced with a 500 GB and has been running smooth until this.
Please help me! Any advice at all is extremely appreciated. Thank you!

Take the HDD out of the MBP and install it in an enclosure. Connect it to another Mac and see if you have access to the HDD. If so, copy what ever files that are important to you to another HDD.
Then you can take the MBP to an Apple store genius bar for a FREE evaluation. Prepare your self for unfavorable news.
Ciao.

[MOOT] UEFI USB Install (from 201306 image) - blank screen during boot

I am trying to install Arch Linux on a Lenovo ThinkPad T431s.
I created a bootable UEFI USB disk image following the instructions on the wiki.
https://wiki.archlinux.org/index.php/UE … B_from_ISO
Attempting to boot from this image I get to a screen that looks like:
Arch Linux archiso x86_64 UEFI USB
UEFI Shell x86_64 v1
UEFI Shell x86_64 v2
After selecting the first option, I get a blank screen.
This appears to be the same (or very similar) to the following issues:
[1] https://bbs.archlinux.org/viewtopic.php?id=151599
[2] https://bbs.archlinux.org/viewtopic.php?id=158530
As suggested by
https://wiki.archlinux.org/index.php/Beginners'_Guide#Preparation
I tried appending a number of things to the initrd line
nomodeset
video=SVIDEO-1:d
i915.modeset=0
with no success (the blank screen was exactly the same).
Some posts in thread [2] indicated that booting in legacy bios mode worked. I created a new disk image (again following the wiki instructions: https://wiki.archlinux.org/index.php/US … ion_Media) and was able to confirm that I could successfully boot from this other image after switching into legacy mode.
In thread [1], there was the suggestion to go into a UEFI shell and try a command like
Shell > fs0:
FS0:\ > cd \arch\boot\x86_64
FS0:\arch\boot\x86_64\ > vmlinuz archisobasedir=arch archisolabel=ARCH_201306 initrd=\arch\boot\x86_64\archiso.img
which I did. After pressing enter nothing happened (the screen did not go blank, all the text remained, no messages appeared).
Eventually in that same thread, a workaround was suggested in this post. I have not tried this because I was unable to understand what exactly was being done, both because of the terse nature of the post and the fact that the referenced article is not in a language which I read (and google translate did not make it clear enough). I was unable to evaluate whether that was a sensible thing to do.
Now, finally, the questions
Firstly, does anyone have any suggestions about how to solve or troubleshoot my blank screen issue?
If not, does anyone have an opinion about which of the workarounds (switching into legacy mode or the one that I don't quite understand yet) would be better? I am not planning to dual boot the system, so I do not need to use UEFI to be win8 friendly, etc.

Neri, did you get any further with this? I just got my own Thinkpad Yoga and am facing the same problems. Everything works fine in legacy Boot but the screen stays black on UEFI boot regardless of the known workarounds.
might it help to first install using legacy boot and later on convert to UEFI?
Not really with Arch directly anyways. What you can do is:
1. Use Fedora 20 USB to boot the sucker up
2. Use Archlinux-bootstrap install (download expand etc)
3. Use refind as the bootmanager seems to solve the dual boot issues
ATM i'm fighting a mkinitcpio segfault. But that is after the installation was basically successful. It would be nice if we can find a way to fix the install medium ...
EDIT:
All sorted out. Unfortunately you'll have to bypass the Archlinux Install medium and resort to the fedora 20 installer. I used the XFCE4
version for a smaller download.
Here are the basic steps for a Dual-Boot setup:
In windows (Disk Management) truncate your C: Drive. I ended up making basically what will became /dev/sda4 smaller and didn't not
touch any partition or free space before that. Here's the final Layout:
/dev/sda:
empty space
1. recovery partition
2. ESP
3. reserved
4. windows
5. Linux Root
6. Linux home
7. Swap
The installation happened from within Fedora Live using an Archlinux Boot strap image according to the Wiki for installing from an
existing Linux and the Wiki Installation Guide. I mounted /dev/sda2 (aka. the existing ESP partition) as /boot and installed refind
according to the wiki. Please note, when you install Arch through the archlinux bootstrap method make sure you pacman -S archlinux-keyring
in the bootstrap chroot first before you run the pacstrap command - it will accelerate the process tremendously!

Blank Screen During Boot

after my latest upgrade I restarted and now the screen goes blank around the point the font changes and it finishes saying kvm disabled by bios. It then goes black and stays black. I've seen an answer posted here: https://bbs.archlinux.org/viewtopic.php?id=86357 in one of the comments. But it's been months since I did any linuxing. So I need some help. How do I mount my root and boot partitions while booted to live media (usb)? I know which is which in lsblk. My next question is what do I then do to chroot into it? I'm guessing mount /dev/sda1 /mnt/root ? Then chroot to it.
Assistance would be much appreciated. Once I get there I can start trying to change some options with mkinitcpip.conf and in Radeon.conf as I have a Radeon card. The changes are listed in wiki here: https://wiki.archlinux.org/index.php/ATI#Disable_KMS but I seem to be having trouble turning modest=0 on while on live media. If someone could assist it would help a lot as my windows box died (of course) and this is my only pc at the moment. I heard this may fix my issue of someone else has another fix please share. Radeon card, 64bit, manufacutrd by HP as HP compaq elite. Has ran arch over a year fine so far and love it compared to other distros
Thanks for the help in advance I feel like a noob I used to be able to do this stuff in my sleep but I've been stuck on a windows server and infrastructure at work for a while now.
Cheers fellow archers.

Sorry was typing on an iPhone. I'll try switching to a new TTY when I get home from work. The screen is powered on, it displays the DVI connection icon in the corner showing it does have a conneciton, everything is just black. I'm booting straight to X. I managed to get in on a live usb, and mount my root home and usr directories. But after doing so I can't seem to get chroot to cooperate. As I recall I just do chroot /mnt/root_mount_point and that should be it yes? Should I use the special arch chroot or regular? I know you use arch chroot when installing but I'm not doing so.
Assuming I finally get chrooted in, I'm hoping modeset = 0 works. From the post I referenced, doing modeset = 0 in radeon.conf after creating /etc/modprobe.d/radeon.conf and doing mkinitcpio -p kernel26 after making changes to /etc/mkinitcpio.conf Not sure what changes to make exactly, but I guess I'll reread the wiki over and over till I get it. I hope this fixes the issue as it did for the other person.
I have a specific quesiton about mkinitcpio -p kernel26... is that the right argument? Should I use kernel26 or is it specific to the machine? I see in the wiki mkinitcpio -p linux. Which is the correct command?
My last update was yesterday. Before that it had been about a month. And I hadn't restarted in about a week or two.
Does this seem correct? Will it fix my issues?
Thanks

This says ati but can in some cases happen on intel with docking stations too:

The most likely problem is the former though. It tries to use both outputs, and the vga uses a much lower res than the dvi, and therefor your monitor goes black because it doesn't like the video mode.
Thank you for answer.
I modified Grub line for adding one more module parameters fbcon=map:1:
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux fbcon=map:1"
and updated grub:
grub-mkconfig -o /boot/grub/grub.cfg
but now after showing Grub table with available systems just frozen video, still I'm able to typing from keyboard to push system forward (encryption password)
I reverse to previous settings.

Monitor blanks off during boot up.
