[Solved/Broken DPM] Hang at boot when switching modes with radeon

When I tried to boot into Arch about a week ago after cleaning some dust out of my case I was met with a nasty surprise, it wouldn't boot properly! Once my system got to the point where it would usually change resolutions (KMS kicks in) my displays (1 DVI, 1 DVI -> VGA) would just shut off (presumably not getting any signal from my GPU a Radeon 5770) and either my keyboards lights (caps/scroll/num) would either be stuck on or be able to be toggled but I don't believe anything was happening in the boot process.
Now me being the inquisitive kind of guy I decided I would be right on the case and ignore Arch until I got bored. I tried out an old Ubuntu 12.04 based distro and everything worked fine, but that's no way to live so I decided to install Debian testing. The install went fine, everything was happy, and I even made it to a tty! But during the boot I noticed a message saying I didn't have the non-free firmware I'd need for my GPU, so I installed that and rebooted.
Much to my pleasure the same issue didn't happen! Instead of only (presumably) locking up my GPU fans were going very fast and loud blowing a bit of extra dust out of my case for me. How convenient! At this point I decided the problem was probably the fault of the firmware, but why did it just start happening now? Perhaps I updated my system before I opened it up; I don't remember if that is the case or not however.
Anyways, Debian testing was a bust so I decided I'd reinstall Arch, so I booted up my trusty flash drive and.... the same thing happened. While I considered the possibility of hardware failure, Windows works the same as it always has and the old distro didn't have any issues aside from generally being old and terrible and my computer is yet to catch on fire. I also ran a small memory test to make sure everything seemed normal enough.
tl;dr Boot fails when KMS initiates (?) / Hardware seems fine / Maybe a problem with new kernel or firmware
Anyone else have issues or a solution?
EDIT: Disabling DPM fixed my issues, but of course I don't have dpm now

You can try building the kernel from git. There is an AUR package.
Or try the drm-fixes-3.16 branch from git://people.freedesktop.org/~agd5f/linux (http://cgit.freedesktop.org/~agd5f/linux/)
For me (HD6870) it fixes the power management. But i had other symptoms: https://bugzilla.kernel.org/show_bug.cgi?id=68571

Muvo TX FM: is the 256mb slightly faster than the 512mb when switching modes?(and starting u

I was just wondering if the muvo tx fm 52 is slightly slower than the muvo tx fm 256 when switching modes ?
because i have the 52 and my dad has the 256 and i noticed there's a difference
both of them have the lastest firmware on them .5.0
both of them are reasonably full / capcaity close to full
when i switch from radio mode to music in folders mode : the transition between the two modes are smooth and immediate on the 256
but when i do this on my 52 : i seem to have to an extra second of waiting time before it goes back into music mode
yeah i know it's a bit nitpicky to bring such a thing up , but i thought it was strange that there would be a difference , since they're both the same model and firmware ( only a difference in capacity between the 2 )
this occurance didn't start to happen until i upgraded it recently to .5.0 ( when this occurance starting appearing )
or maybe it's just my 52 that does this ?
anyway another thing that's strange that i've tested :
if i do switch back to an older firmware version for my 52mb : this extra delay between switching modes is non-existant / goes away
( it was non-existant before i upgraded to the new firmware )
also another thing i've noticed is the 256 seems to be faster at starting up after turning on too
when i first turn it on , only takes till the /4 of the sand in the egg timer icon and drained to the bottom before it starts playing music
with the 52 , it doesn't start playing music until all the sand in egg timer icon has drained to the bottom ( a second longer wait before the music starts playing )
also another thing to note is that
the firmware that came with the 256 , was .5.0 ( bought in april )
i bought the 256 a couple of months ago
with my 52 , which i had since december : i've used firmware old firmware that came with that ( i think .0.04 ) ( until switching to the newest firmware recently )
i was just wondering what's calling this extra seconds worth of delay in my 52 , that's not present in the 256 ?Message Edited by low-quality on 07-04-2005 0:43 PMMessage Edited by low-quality on 07-05-2005 04:08 AMMessage Edited by low-quality on 07-05-2005 05:37 AMMessage Edited by low-quality on 07-05-2005 05:38 AMMessage Edited by low-quality on 07-05-2005 05:38 AMMessage Edited by low-quality on 07-05-2005 05:38 AMMessage Edited by low-quality on 07-05-2005 05:39 AMMessage Edited by low-quality on 07-05-2005 05:39 AMMessage Edited by low-quality on 07-05-2005 05:39 AMMessage Edited by low-quality on 07-05-2005 05:40 AMMessage Edited by low-quality on 07-05-2005 05:40 AMMessage Edited by low-quality on 07-05-2005 05:42 AM

Sounds like it could be because of the capacity difference, maybe a mod could confirm this.

Booting into 64bit mode with Mac Pro 2009

I am trying to boot into 64bit mode with a 2009 Mac Pro 2.93 Quad core machine. I tried holding down 6 and 4 when restarting but no luck, it staill says no in the profiler. Any ideas why?

If you'd like your Mac to always start up in 64 bit mode without having to hold down any keys, do this:
Here's the configuration file approach for always booting into 64-bit. This is the best way to make your Mac always start up 64 bit as the only thing necessary is to alter one line of a configuration file. You can do that by opening the Terminal and entering:
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.Boot 'Kernel Flags' 'arch=x86_64'
To return to 32 bit mode, you would repeat the command but enter an empty string, which would just be the single quotes (where arch=x86_64 is) with nothing in between.
sudo defaults write /Library/Preferences/SystemConfiguration/com.apple.Boot 'Kernel Flags' ''
These commands are all one line, they're just wrapping here.
If at any point you find you need to start up in 32 bit mode for a single use, just as you held down the 6 and 4 keys for 64 bit, you can hold down the 3 and 2 keys for a temporary change. No need to keep changing the config file over and over.

Cannot boot into Safe Mode with Networking - Windows 8.1 Update

I'm trying to boot into safe mode with networking. I can successfully boot into Safe Mode, but my Network Access is always disabled.
I've tried msconfig / Click on Restart / Restart Now from the Update and Recovery menu in 'Change PC Settings'. They all eventually get me to the Same boot options menu which says ... F4 for Safe mode, F5 for Safe mode with Networking etc.. I
select the F5 Safe mode with Networking and it re-boots into Safe mode but I have no network access.
I'm connecting to my home ADSL, no proxy required. If I boot normally I have network & internet access, but in 'F5 Safe mode with Networking' my networking is disabled.
Windows 8.1 Pro x64

I can see that I am actually connected to my router, but the network icon still shows as disconnected.
What about the Network list via the Settings charm (Win-I)? Last week I was having problems with that one after long sleeps. Later I realized that although I could see the icon in the Settings charm (as normal) when I clicked on it, it still
showed the same icon as I was expecting; the difference is that it didn't show "Connected"; so, clicking on the icon proved that it was offering a Connect button and clicking that finally got me connected. Meanwhile the troubleshooters were misleading
at best and destructive at worst, suggesting I power things off, etc. I don't know if there was a fix for this specific symptom or whether I just tried a different path but yesterday instead of trying the above procedure I tried to see what the Network
troubleshooter associated with IE's "unable to connect" page would do; amazingly it identified the problem precisely. That connection had somehow acquired a connect manually attribute. The troubleshooter offered to fix that problem for me
and I accepted. Since then, no more problem.

Initramfs seems broken, system hangs at boot after gummiboot menu

Did a full system update yesterday, and when rebooting the system hanged directly after the gummiboot menu with a black screen and a rainbowlike-colored bar in a pattern that looks like pink noise covering the top 10% of the screen. It seems to be a problem when loading the initial ramdisk. I have tried rebuilding with mkikitcpio, tested downgrading the kernel and rebuilding initramfs, triple-double-checked the filenames, and even verified that it doesn't look like that when the filenames are wrong. I also tried simply reinstalling the latest kernel from a chroot, but it didn't help.
I have pinned down the problem to the initial ramdisk, but can't figure out what else to do with this. I don't really want to do a full reinstall if it's possible to avoid. The system is a lenovo thinkpad w530 and I boot arch linux in uefi mode using gummiboot.

Unfortunately, no, I still use EXT4 on my system. However, what do you mean when you say "got unmarked as the default one"? Is that something local to rEFInd, or what do you mean?
I have tried downgrading to Linux 3.7.5-1, but that did not help unfortunately. My system worked with 3.7.5-1, when I upgraded to 3.7.6-1 it stopped working, and downgrading didn't help. I'll try downgrading to a 3.6 version though.

W520 hangs on boot when a WD SES USB drive is connected

Hi,
Computer: W520
Hard drive: Western Digital - My Passport (SES Drive - encrypted)
When I boot with the usb hard drive connected to any usb port on the computer, the computer hangs forever at boot time. If I unplug the drive and reboot, everything is fine. I was able to fix the problem by disabling the USB support in the bios but then, none of the USB ports work in Windows.
I believe this is due to the SES function of the WD usb hard drive (see: http://wdc.custhelp.com/app/answers/detail/a_id/3701/~/computer-freezes-when-it-restarts-with-a-wd-m...
Also, a previous post with a similar problem was written on this board but provided no working solution (see: http://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-won-t-boot-with-SES-device-connected-to-U...
Thanks in advance for your help.

Hello jeantremblay44,
As I understand the laptop cannot boot if the external USB drive is connected.
Kindly try the following troubleshooting step
You can make the USB boot disable from BIOS and make the first boot device as Hard Disk

[SOLVED] New installation hangs on boot at two different places

Hello
I recently made my another attempt at installing arch on a new desktop build. Previous successful attempts were old laptops.
I followed the Beginner's Guide on the Arch wiki.
Currently it stops at one of two places in the boot process:
1. [ OK ] Found device Samsung_SSD_850_EVO_500GB BOOTARCH
Starting File System Check on /dev/sdb6…
2. [ OK ] Started Journal Service
[ OK ] Started udev Kernel Device Manager
I can not consistently recreate either scenario, but it seems to be random which of the two places it stops. Cold boot and CTRL ALT Delete. I doubt that has anything to do with it, but thought I'd add it anyway.
Current setup:
Hardware:
Motherboard - ASUS Z97 Pro (using ethernet adapter and sound on here)
Processor - Intel 4790K
Memory - 16 GB
Graphics - Gigabyte G1 Nvidia GTX 970 SLI x2
Storage - Samsung 850 SSD 500 GB and WD Black HDD 3 TB
I've also configured it to use a static IP
I started this journey by using the live Gparted CD to create partitions. I created two partitions on the SSD. One for windows 8.1 and one for linux. I then created two partitions on the HDD. One for windows, one for linux.
I installed windows 8.1 first. It divided up the partition I gave it. I am able to run Windows. Once that was done I began installing Arch.
I used the Feb 2015 ISO from the torrent.
Current partition scheme for linux:
sda1 /home
sda3 /swap
sda4 /var
sdb1 /
sdb6 /boot
sda is the HDD and sdb is the SSD
The other partitions not listed are for windows. To boot into windows, I use F8 to choose the windows boot manager partition. It currently defaults to the linux partition.
During the install, I mounted the root partition first. I then created directories for each of the other partitions and then mounted them. Home, var, and root are all ext4. Boot is FAT32, and Swap is swap.
I read where I made a couple of mistakes the first attempt on this computer and did a wipe and reinstall again. First mistake was not knowing that /boot needed to be FAT. I then learned that /swap does not need to be in the fstab. I also learned that a FAT partition can not use UUID in the fstab so I took that out and just used /dev/sdb6 instead.
I have run out of things to search for at this point and need help to continue moving forward.
Bellow is the current /etc/fstab. It was generated using
genfstab -U -p /mnt >> /mnt/etc/fstab
and then edited as noted above
#/dev/sdb1 LABEL=archroot
UUID=xxxxxxxxxxxxxxx / ext4 rw,relatime,data=ordered 0 1
#/dev/sdb6 LABEL=BOOTARCH
#UUID=xxxxxxxxx
/dev/sdb6 /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2
# /dev/sda1 LABEL=linux\134x20home

#/dev/sda4 LABEL=archvar
UUID=xxxxxxxxxx /var ext4 rw,relatime,data=ordered 0 2
#/dev/sda3
#UUID=xxxxxxxxxxxxxx none swap defaults 0 0
Thanks for any help that can be provided

I tried removing gummiboot and installed GRUB2. That didn't work.
As to the UUID's, I just typed in xxxxx's for the post because I didn't feel like transcribing random letters and numbers.
So after reading Head_on_a_Stick's suggestion, I redid my partitions and reinstalled arch again following the Beginner's wiki page and using gummiboot
New Partitions are as follows:
sda1 /home
sda3 /swap
sda4 /var
sdb1 /
sdb3 /boot (originally created from windows install)
Also, I took a screenshot from Gparted of the two disks if there is any info on there that may be of use

Audio mutes when switching modes in Audio Cons

I have an Xfi Platinum that is working great except one annoying problem. Ever since I upgraded the drivers to the latest version, everytime I switch audio modes, for example from game to entertainment, the sound mutes on my system. I have to open the Windows XP sound control to uncheck mute every time. Has anybody experienced this problem and have a fix for it's I downloaded the mode switching program from a link on this forum, but it does the same thing. Thank you!

Don't know if this will help... Try changing the multi-track preview/playback settings (press F4)... If the playback buffer is too big or too small you may get dropouts...
Also try to defrag the hard drive with virtual memory turned off. With VM off it may run slow, but it should defrag the swap file as well making your drive super optimized. You may have to boot in safe mode to make it work though... Of course you can turn the VM back on when you're done...
Clean out the dust from the computer and make sure it isn't over heating...???

Why is the Camera app so slow when switching modes?

When I switch modes between still-photo and video (or back) in the Camera application, there is a 2-3 second pause while the "iris" appears and disappears. Ok, that's not very long, but when you are in a rush to capture "that moment" it can be all the difference between "great" and "rats!".
I get that an app can take a few seconds to load, but switching camera modes should be nearly instantaneous, shouldnt it? Do other people see the same delay, or is it just me? Are there any known tweaks to improve this delay?

I don't know why Apple doesn't fix this problem or even acknowledge it. I have had this problem since 1.1.2. Upgrading through 1.1.3, 1.1.4 and on the 2.1 has not helped. My SMS loading time varies between 3 and 10 seconds. I maintain all my SMS messages deleted (which I should not have to do). Due to lack of support from Apple I purchased a Nokia phone for my son. At least basic phone features work like they should.

MacBook Pro only boots in safe mode with pink vertical stripes across screen.

So on Friday night I was using Chrome on my MacBook Pro, when all of a sudden little squares of light flashed randomly across the whole screen and everything but the mouse froze. I thought that was weird, so after a few minutes I forced my computer to shutdown. I waited a little and then turned it back on, and opened Chrome again. The same thing happened again, so I forced shut down, backed up Time Machine and ran a virus scan. Nothing came up, so I put it to sleep and and went to bed. Then Saturday morning I went to open my laptop and it was off, which was weird, so I went to turn it on. After the apple logo and spinning gear went away, it booted to a light blue screen and stayed there. Again I waited and nothing happened, so I held the power button down until it turned off. I tried again but the same thing happened, so I booted in Safe Mode.
This time there were inch long vertical bars of horizontal lines, kind of confusing but here are two pictures I took of the screen that hopefully help. http://imgur.com/oj2WbZL and http://imgur.com/O1hwJ1B . When it finally loaded I had another issue, I had 6 pink vertical bars across the screen and a box of pink horizontal stripes around my pointer, http://imgur.com/BJBzu74 . I performed an extended Apple Hardware Test and after 17 minutes it found no issues, and as it performed the test the lines got whiter and made the screen harder to see http://imgur.com/XahBD3s .
I got my laptop June 2011, so it's not that old. I just want to know what this problem could be. I don't know if it's the connection from the screen to the computer, the hard drive, the logic board or something else. I'm really worried that it's something major, so any help is greatly appreciated.
Thank you in advance!

This is a GPU problem. It's normal that you see that the problem is random, but the fact that your Mac is only starting up in safe mode indicates that your Mac can only start up if the VGA driver is used. Moreover, if you open Console, you should start seeing "GPU Debug Info Start", which indicates a GPU failure.
As you have a backup, take the MacBook to an Apple Store or reseller. In the case of the MacBook Pro, the GPU is soldered onto the logic board, so the whole logic board has to be replaced, being a very expensive repair.

How do I boot into recovery mode with wireless keyboard

I am unable to boot into recovery mode using either cmd-R or holding down the alt key. How is it supposed to work?
Message was edited by: Niklas Brunberg (better title)

I understand your concerns - I'm glad both of my machines are dual bootable (just in case) and I have my Snow Leopard install disks..... However, this is what Apple has decided, so we need to find the best way to deal with it. Personally, I've tested the recovery mode several times and, at least on my machine, it was not reliable (i.e. it wouldn't work - I tried it again and it did, but it spent more than an hour downloading the entire 4 GB installer again and then another 30 minutes installing it), and on a third try, I found that it had vanished because I had cloned by drive. When you clone, only your system is cloned, not the extra partition.
So, I've decided to rely on a) my bootable clones and b) a copy of the installer (.dmg) in case my clones fail. I don't feel comfortable relying on something that requires an internet connection and a full download to work. But, that works for me; you may want to take a different approach.

Unable to boot into safe mode with FileVault 2 enabled

I was trying to boot into safe mode earlier to try and fix a few things. It looks like I can't and I suspect it is because of FV2.
When the system starts I press shift after the tone, but then I have to release shift and enter the password and then Lion will only boot into normal mode.
I've also tried with sudo nvram boot-args="-x" from the terminal, but while it seesm that this way Lion starts to boot into safe mode, after a while it just restarts as if something crashed etc and then again, I have to enter the password for FV and all again as in a loop, i.e. Lion won't even start this way.
So I went into the recovery mode and I could make Lion start again at least in normale mode with sudo nvram boot-args="".
Any idea of what could be preventing Lion from entering safe mode?
Thanks in advance

The symptom may be unrelated to FileVault 2. I encountered the symptom with FileVault 2 disabled and with backward conversion (decryption) complete.
Apple reference for my bug report: 152162960. If the symptoms on your Mac compare to those on mine: progress may seem to cease during safe fsck.
Vito, as you are comfortable with the nvram command, please try the following:
sudo nvram boot-args="-v -x"
Restart the computer and note the last verbose lines that appear before you sense that progress has ceased. Then please add a note of those lines to this topic.
Additional questions
What model is your Mac?

MacBook Pro Retina 15" mid-2012 won't boot in clamshell mode with an external display attached

I have a 15" MBPr mid-2012 running OS X 10.10.1. The system won't boot in clamshell mode (power is connected, lid shut) with an external display attached via an Apple Thunderbolt->DVI adapter. it boots fine if the lid is open. It isn't the adapter or the display since my 15" MBPr mid-2014 boots up just fine connected to the same adapter and monitor. And this system used to boot like this just fine some while ago (probably before it was upgraded to Yosemite). I've reset the NVRAM (twice) to no avail.
Has anyone encounter this? Anyone have a solution? Should I try an SMC reset (always a bit nervous about that)? Might it be a driver issue in Yosemite?
Thanks.

In a normal Boot this happens - if I start in Safe Mode with Networking the page is normal and loads correctly.
I was wondering if any part of Firefox is disabled during a Safe Mode boot which could be causing this issue. The website is

O/S Vista Home SP2. Firefox 3.6.17. Kaspersky AV but for this exercise has been completely disabled

Thanks Luis.
The only difference is the subscriptiion price for students and teachers.

New install hangs on boot when GDM or LXDM services are enabled

Greetings Arch users,
I've been trying out installing Arch on a USB drive in order to get familiar with the process and use it on my main machine in the future. I've been following the Beginners' Guide, and after a few hiccups, I managed to install what appears to be a fully-functional Arch system onto a 16 GB USB drive, albeit without a window manager or desktop environment.
When I tried that is where I ran into problems. I installed X, vesa driver, and GNOME and enabled gdm.service, and upon the next reboot the system hung after or in the middle of the fsck process, exactly as described in this thread.
rebooted, hangs after the fsck bit where it says something like /dev/sda4: clean, 112977/9296096 files, 185427/21217024 blocks
I just get the blinking cursor. I left it there long enough to take a nap and nothing else came up.
Examining the journalctl output, I see an error exactly like mentioned in this thread:
GLib-GObject-CRITICAL: g_object_ref: assertion 'object->refcount > 0' failed
GLib-GObject-CRITICAL: g_object_unref: assertion 'object->refcount > 0' failed
Chrooting into the system and disabling gdm.service allowed for normal boot.
Well, I thought, maybe there's an issue with GDM or GNOME. I'll try LXDE and LXDM instead. Unfortunately, that hung at the exact same point in the loading process. Looking at the journalctl, I saw an output exactly like what was described in this thread:
Lxdm.service main process exited code=exited status=1/FAILURE
lxdm.service entered failed state
I'm stumped. I've searched and haven't come up with anything. Does anyone have any ideas about what might be the cause? What additional information would be helpful in diagnosing the issue? Thank you for your help.

GDM then restarts immediately. Problem recurring each boot.
Can you check the logs (dmesg, journalctl, xorg) and see if there are any differences for the startup of GDM before and after a successful GDM start.
Technically from the lack of information you provided it's not possible to state if you actually have the same issue or not. It might be better for you to start your own separate thread.
If you start your separate thread please provide some more details so people don't need to start guessing.
I think I'll just RTM.
