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

[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 Win XP Pro

When i boot my computer (specs below) the Corecell logo comes up for a few seconds, the the screen will go blank for most of the rest of the boot. it'll go about 45 seconds with a blank screen, then finally the windows XP logo will come on the screen, then a few seconds later, the windows desktop appears. Also seems that the first 30 seconds or so of this blank screen, the hard drive LED isn't showing activity, then finally it'll kick in and the Windows XP logo shows up shortly after.
no big deal really, just wondering why i get this blank screen. We have tons of Win XP pro machines at my job, and none of them boot with this blank screen. I have seen other Win XP machines do this here and there, any ideas why?
- Kip
(just wanted to clarify what i mean by "blank". i mean black screen. video signal is being fed to the screen, just nothing but the black.)

My God! You're running XP!! Have you upgraded from 2000? Do you have any autostart program connected to an instant messaging or SQL server?

Blank screen during boot, missing video on tty console

I have black screen when booting from docking station where is DVI video output. On laptop itself and over VGA is OK.
Tried modify GRUB2:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet”
for
GRUB_CMDLINE_LINUX_DEFAULT=“i915.modeset=1”
but still the same and can't get video after switch to tty (ctrl+alt+F1) as well
I compare with Debian where tty works fine
found in folder: /etc/modprobe.d/i915-kms.conf
where is:
options i915 modeset=1
in Arch missing this file, any idea what to check?

This says ati but can in some cases happen on intel with docking stations too:
https://wiki.archlinux.org/index.php/At … rks_in_KMS
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.

[Dell E5510] Blank screen during and after boot

Hello,
I performed system update some time ago (2 or 3 weeks) and left my computer unused. Today I tried to power on it and I was very surprised, because I didn't see anything on screen during boot and after it. I rebooted computer in fallback mode (I also added "i915.modeset=0" to kernel init args), and I saw command line. Then I updated whole system and rebooted it again - no luck again blank screen during boot and after.
I rebooted it one more time, but with default kernel (I disabled KMS again via GRUB command line) and I saw systemd output during boot. I teems, that all services were started successfully, because all messages were prefixed with "OK". Then I cloud only use command line, because Gnome 3 was not running under seventh console.
Any idea what is going one here?

Hi ausrius517,
Sorry to hear you are having a problem with your device.
Have you tried performing the following resets to see if it will solve your issue:
Soft Reset - this will not delete and data off your device.
Enter *#7780# into your phone's keypad and when prompted, enter 12345 (default code)
If there are not too much data on your device and you have made a backup, you can go for the hard reset option below.
Hard Reset - this will wipe all data off your device, so a backup is recommeded before doing this.
Enter *#7370# into your phone's keypad and when prompted, enter 12345 (default code)

Satellite A85-s107 - blank screen on boot up using battery power

Satellite A85-s107 blank screen on boot up using battery power
When I boot up A85-s107 in battery power, it is getting booted up in the background, but my screen is blank.
After that if I connect it to AC power and switch off/on the laptop power button, the display comes back to life.
There is no problem when I boot up when connected to AC power.
Battery is fully charged and computer will run off battery if I remove AC after boootup
Any suggestions?
Ps:
also notice that when I remove AC and then reconnect I have to start the computer twice as it doesnt boot the 1st time?

hi nick34_99,
sounds to me like a bad charging electronic...
i got this issue on my sat3000 too, but only when battery is not fully charged...
start the unit with a dos-disc (freedos has an cd image) and let the battery run "dry"...
after that boot without battery (ac-adapter connected of course) and log on.
after that shut down insert battery and try with batt only....
this trick has done magic on my machine...

How to blank screen during music usage with Apple TV.

How do a select a blank screen as a screen saver when listening to music. I would like to save energy and minimize tv screen usage. I don't want to show pictures or anything. My screen is currently on all day as I listen to music. Any adjustments with my Samsung tv during Apple TV stops Apple TV. I have an Apple TV 3.

Like I said, the Tv would need to be on unless connected via optical, that is not software related. Not a lot of energy would be saved by having a blank screen. The majority do use the screensaver to showcase their pictures and there wouldn't be a lot of call for having a blank screen.

Blank screen & no booting after running BIOS update on Satellite A200-1AE

Here is my problem with my A200-1AE (PSAECE) Notebook:
I downloaded the latest BIOS update from the Toshiba download drivers library to install Win XP since finally the drivers are realized. (Note the update clearly stated to run ONLY if you want to install XP on you NB).
So I unzipped the file and after hitting the .exe file it started updating the BIOS on its own without me giving the liberty to do so. Half way the N/B froze for about 20 minutes and as I didnt know what else to do so I reset it.
Result? The NB does NOT boot. I press the power button, the Hard Drive icon flashes 2-3 times as well as the DVD drive, I get a blank screen and the power cord & power button icons constantly on. I removed the battery and the power cord for 48 hours hoping it will reset the BIOS on its own to no avail.
The BIOS battery is under the touchpad which means I have to disassemble the whole laptop and I am not ready to do so. I dont know if on the motherboard there are BIOS reset jumpers and I need someones help as to what I should do. I am starting to think that things where MUCH easier back to when I just had a desktop PC.
THERE must be something I can do other that taking it to the service center and pay half the value of the laptop in repairs.... PLS HELP Im desperate....

Hi there,
first of all: a notebook is not a desktop and such mobile computer does not have jumpers like a deskop computer. They surely have something to delete the BIOS but I am not so sure IF resetting the BIOS could help you.
I guess you will have to send your machine to a service center for repair because in such cases you will have no other option. Do you have still warranty on this machine?

Lumia 800 constant blank screen during calls

hi guys,
I have a nokia lumia 800,
when im on a call the screen stays blank so i cant access any of the in call options? i dont have a screen protector on the phone, i have run the diagnostics app and the the proximity sensor is responding fine!!! so it leads me to think its a software issue? is this a common problem or am i doing something wrong?
hope you can help.
daniel

The screen gets turned off during a phone call when the proximity sensor is covered. This is done to avoid accidental touch screen actions when you are in a call.
If the screen gets turned off immediately when dialing a number or receiving a call, check that your phone does not have any object which may cause detection. There are various non-Nokia original screen protectors sold in the market which cover the proximity sensor causing blank screen issues during calls.
You can take the following steps to check the issue. If the screen keeps turned off, the protector may not be of the right size and will block the sensor on the upper part of the front side. Then either remove the protector or cut off the plastic from the blocking area.
Make or receive a call with the phone.
Once the phone is in a call place your hand 1cm above the screen and display will turn off.
Remove your hand and display shall turn back on.
Repeat the test steps 1,2,3 for 3 times to verify the proximity sensor function.

Lumia 930 blank screen during call

My Lumia 930 screen goes blank during all calls. Iti is black whether the phone is next to my ear or not. In practice I cannot end a call or do anything else cause the screen keyboard is not available.
My son has a Lumia 920 which had very much the same problem but it was somehow fixed when the device was at Nokia service last year because of some camera problems. No idea still about the root cause of that case either.
Any idea how to fix my blank screen problem?

I have the exact same issue with my brand new Lumia 930 - the screen goes black (a bit randomly) when talking on the phone. I used a trick decribed in a post with the same issue on a 920, which is to firmly wipe just above the N in Nokia in the top right corner on the phone (where the sensors are) which helps. However, it is not really fixing the problem.
Is there anybody knowing another solution but to return the phone, which feels a bit cumbersome to say the least?
Thanks,
Erik

Blank screen after boot - After update.

Hello!
I have the following problem with my arch dist:
I recently - and after several weeks without touching it - updated my arch but, after rebooting, the laptop screen went blank just after booting up. Using the fallback boot resulted in the same ... well.. result. This is as much as i can describe since i don´t know how to access a comand line in this context, in order to test/check what´s going on. Anyone can help me?
Thanks

Assuming you are using grub, you can edit /boot/grub/menu.lst when grub is loading, in order to force it to not boot into X. On boot, select your normal arch linux entry from to boot list (don't press enter) and type e to edit the menu.lst Press e again on the kernel line and append this number:
kernel /vmlinuz26 root=/dev/sda3 resume=/dev/sda5 ro 1
Press enter and then you boot it by pressing b. It is the number at the end that defines the run level, in this case 1 (single user). This will allow you to boot into console as root.
Edit: I meant run level 1 (single user)

Blank screen on boot but only somtimes

After updating to kernel 3.16.1-1, sometimes booting up leads to a blank screen. In this blank screen state, everything seems to be working, the numlock/capslock keys light up when toggled and pushing the power button does a full shutdown which I've set it up to do, just no screen. Interestingly, adding the kernel option `nomodeset` seems to fix this but I haven't touched any video drivers whatsoever and don't use proprietary drivers either, I use nouveau. Even more interestingly, this only happens sometimes. I happened to save logs for when this blank screen state happens and when everything boots up OK.
Here is Xorg.log for blank screen:
http://sprunge.us/VcLE
Here is the normal Xorg.log:
http://sprunge.us/PRdG
Here is the journal boot logs for blank screen:
http://sprunge.us/HJMQ
And here is the normal journal boot logs:
http://sprunge.us/FdRe
I'm not sure if anything looks out of the ordinary, but any suggestions would help
Thanks.

What setup is yours?
Desktop? laptop?
I think you need the newer nvidia drivers and not nvidia-304xx series.

Green line on screen during boot only

hi, i've a problem with my macbook pro 13" late 2011! After an re-initialization on my macbook happens that only during boot i see a green vertical line on the right side of my display and it disappear after login. This green line starts from the upper side and finish to the down side. Can it be a problem deriverd from a bad os installation??
i'm attaching a photo but i'm sorry for bad image.
thanks for the help!

Try a pram reset:
Shut down your Mac.
Locate the following keys on the keyboard: Option, Command (⌘), P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on your Mac.
Immediately press and hold the Option-Command-P-R keys. You must press this key combination before the gray screen appears. Continue holding the keys down until your Mac restarts, and you hear the startup sound for the second time.
Release the keys.
