[Bug 740126] Re: Disabling an output can cause vblank events to be missed
I am using Linux Kernel 3 on Natty and now I get the problem again. I was with the proposed kernel with the fix found in here (see #45) and I never had a freeze again, but after upgrading to Linux 3 my system got really bad. It's heavier to operate, takes ages to boot and I get the freeze whenever I close my laptop lid or let it rest for more than 20 minutes. If there's any info about what I should do (even downgrading would be a possibility, I just can't activate the menu on my boot to select the kernels, and I'm on a Natty only computer) Thanks everyone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: Disabling an output can cause vblank events to be missed To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/740126/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Seth yes the correct versions of the kernel in proposed are: linux-image v2.6.38-11.47 linux-headers v2.6.38-11.47 but that version is from Fri, 15 Jul 2011 that is 4 days earlier than your comment.

@Marco, unfortunately we've had some delays in releasing a kernel update to natty due to regressions that we picked up from the upstream stable kernel. As a result we had to temporarily stopped taking stable updates. All known regressions are fixed in the current proposed kernel, and assuming no more regressions are found it should move to updates soon, at which point we can start taking upstream stable updates again.

[Bug 740126] Re: Disabling an output can cause vblank events to be missed
Just to fill in my little bit of experience (as I've been reading about the same glitch I notice): other than the prettyor ugly workarounds proposed in this thread, Ctrl-Alt-Bksp works as well. I'm running on a toshiba satellite P200, with GM965/GL960 integrated chip, and I've noticed a couple more behaviours not listed here: 1) When restoring from screensaver's screen power off, I see the normal desktop screen as if the screensaver never kicked in (windows are all there), I can move the pointer around, but it's as if the screensaver was actually on; in other words, it's a variant of the "blank frozen screensaver" where instead of the blank screen I see the normal desktop with which I cannot interact; more often than not, when that happens, after a while the screen goes back to blank and I get the regular password dialogue, from which I can then proceed to uset he laptop normally; this time though, it just stayed like that, visibile windows on the background, pointer moveable with no effects whatsoever... Ctrl- Alt-Bksp for me 2) If I try and do ctrl-alt-f1, and then again ctrl-alt-f7, I often get no the blank screen anymore, but the last text screen before gdm started, as if I had set the verbose boot mode on, but that screen i cannot interact with, I can type characters in there that are displayed on screen, but issuing commands or key combinations deals no effect (including ctrl-alt-bksp); sometimes, switching back to ttty1 and then to ctrl-alt-f7,a few times, shows the blank screen again, and I can ctrl-alt-bksp out of it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: Disabling an output can cause vblank events to be missed To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/740126/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry if this is answered (indirectly even) elsewhere - but is this fix (patch from #83) expected to be be backported to a natty kernel ?

[Bug 740126] Re: Disabling an output can cause vblank events to be missed
Hello, I'm running on a ThinkPad T500 with dual video. Currently have been running with the build-in Intel graphics adaptor (due to battery life). I may switch to the external ATI Radeon 3850 (I think that's what my laptop has...) and test if that resolves the problem. One theory I have is that the problem is related to the Compiz process providing 3D graphics for Unity, and that this is related to the HW we are running; i.e. if we run the Intel on-board graphics adaptor, it might not have 3D support in HW, hence demanding other things from the SW than if we run on 3D enabled graphics adaptors. Does this sound as a possibility, anyone?? My solution to the problem (when coming back to my laptop with "frozen" screensaver) has been to press CTRL+ALT+F1 and then log in to the console in tty1. From here, I run ps -ef --sort time to see which processes have been running for a long time. 1) kill does not help --> doesn't even remove the screensaver photo from the display even though the process dies. 2) kill does not kill the process --> no change 3) kill -9 does actually kill compiz, and at this point pressing CTRL+ALT+F7 (or F8) takes me back to the Gnome session, which is now flashing a bit, then refreshing and coming up again, seemingly normal. Most of the times, I'm able to get back into my session with all applications still running after step 3) above. However, it has also happened that I got a new, blank session with no apps running. My 5 cents today is that this is a problem related to compiz and 3D rendering, and that it might be related to the graphics adaptor used, including whether the computer is equipped with 3D suppot in HW.

I have been trying to get reproduce the bug to capture dmesg, i915_error_state and even backtraces from my gdm session, but I am not sure what triggers it yet. So far, it seems that it freezes when the screensaver was running for some time BECAUSE IT HAD TURNED MY SCREEN OFF due to the energy policy... I had since disengaged the energy control option to never turn my screen off again, so far it has not frozen my system again.

[Bug 740126] Re: Disabling an output can cause vblank events to be missed
Hi everyone I think I got this bug running Natty on a Dell Inspiron 1545 Laptop. For me it always happened when the laptop was left idle, sometimes after the display turned off others even before that (possibly with the lid closed). I'll try the Kernel suggested on #46 and #53. I'm subscribing and will report back if I get it again. If anyone can tell me how to help debugging it I'll be happy to be of any help.

I as well, the test kernel extends the amount of time the machine can stay alive without freezing, but it still freezes after a few hours of having the lid closed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/740126 Title: Disabling an output can cause vblank events to be missed -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 740126] Re: Disabling an output can cause vblank events to be missed
I've noticed that for me it only occurs after I've been away from the machine for a while.

[Bug 740126] Re: Disabling an output can cause vblank events to be missed
** Summary changed:
- Something blocks compiz randomly several times per day
+ Disabling an output can cause vblank events to be missed
** Description changed:
+ When an output gets disabled - by being switched off by DPMS, unplugged,
+ etc - it's possible for applications to have pending vblank events
+ waiting on this output. If this occurs, the application will never
+ receive the vblank event. This manifests as the app appearing to hang
+ (in poll() on the X connection, if you attach GDB).
+
Binary package hint: compiz
This seems to happen when I'm not at my laptop (ie, when the screensaver
has activated usually). When I return to my laptop, I find it in a state
which appears to be completely frozen (ie, nothing gets repainted on the
screen). However, I can switch to a console and things appear to be
working normally. I can send a SIGKILL to compiz and start another WM,
and then everything starts working normally again (although if I restart
compiz, it often crashes until I've restarted my laptop).
If I attach gdb to the hung compiz, I always see a trace which looks
like this:
