[Ubuntu-x-swat] [Bug 987153] Re: Xorg freeze
Greetings, People, have any of you verified if it fixes the issue for you to disable power management? .. I know it is not a *fix*, specially for a laptop (battery life would suffer a lot), but I just want to know if we are having the same issue.

[Ubuntu-x-swat] [Bug 987153] Re: Xorg freeze
Hi Hansen, No, my CPU is A8-3850 (no external video card, just the included HD 6550D). Also, I have to inform that after almost 7 hours idle the machine didn't crashed. I disabled power management (ie, left only the screen saver, but screen is never put to sleep). Also, before the update to 12.04 turning off V-sync would cure the problem for me (also, avoiding fully preemptive kernel, ie: forced preemption enabled would cause a certain freeze). My kernel right now has voluntary preemption (one of the attempts to fix the problem was to use a custom kernel, right now I'm using a custom-built 3.2.16 kernel). If the machine doesn't freeze for the rest of the day, I'll reboot and switch to Ubuntu kernel to test there too.

[Ubuntu-x-swat] [Bug 987153] Re: Xorg freeze
Greetings, Another update: almost 3 hours after moving again to Ubuntu kernel, with disabled display power management, the system is working just fine. I think the problem shows itself when the video card goes into energy save mode.

[Ubuntu-x-swat] [Bug 987153] Re: Xorg freeze
Greetings, I seem to be having the same problem. While using 11.10 (ie, before updating) this problem used to happen under two situations: 1. If I used a low-latency kernel (ie: fully preemptive). I switched to voluntary preemption. 2. If I enabled V-Sync + Escritorio libre de fragmentaciones (I don't get why ATI control center is in Spanish in my system, whereas the rest of the system is in English... I'll try to get the English name later). 3. You leave the desktop alone (ie: idle). However, now on 12.04, this just happaned, only V-Sync was enabled, I tried to disable V-sync, and I'm waiting if that helped. By the way, the freeze applies only to X server (that ends up using 100% CPU), I was able to ssh to my machine and reboot it. Anyway, from last X freeze, I got this on Xorg.log: [ 29349.258] [mi] EQ overflowing. Additional events will be discarded until existing events are processed.

[Ubuntu-x-swat] [Bug 987153] Re: Xorg freeze
Greetings, Even more information: I turned off vsync, and the freeze happened again, this happens after some time idle (maybe related to power management). On other information, now I tried from the ssh session to kill X server and kdm (yes, I'm using kde), first with signal 15, then with signal 9. The processes went down, but even though keyboard seemed to start working, I had no video. I tried to start kdm again, and now the machine crashed. Around the crash time I found a related message on the logs, in addition to the ones on Xorg.0.lo: May 9 15:02:35 machine kernel: [30439.945854] [fglrx] IRQ 55 Disabled Also, Xorg.0.log Find attached Xorg.0.log file (where other interesting messages are). ** Attachment added: Xorg.0.log from the machine during the X freeze. https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/987153/+attachment/3138954/+files/Xorg.0.log -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/987153 Title: Xorg freeze To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/987153/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
