[i915] xserver freeze on switching VGA1/LVDS1

[Max]

I can easily freeze xserver on my Asus F80L laptop
with just installed Ubuntu 12.04
when the external monitor (LG L2000CP) is connected:

xrandr --output LVDS1 --off --output VGA1 --auto
xrandr --output VGA1 --off --output LVDS1 --auto
xrandr --output LVDS1 --off --output VGA1 --auto

Here the both screens are dark, so I have to switch
to a console and back (Ctrl+Alt+F1, Ctrl-Alt+F7).
No errors in Xorg.0.log and /sys/kernel/debug/dri/0/i915_error_state,
but a new line in dmesg:
[ 1564.394016] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id

Before the next command I run a script which collects some info a minute later

xrandr --output VGA1 --off --output LVDS1 --auto

The both screens become dark again, but now the keyboard does not work
(except magic SysRq keys).

i915_error_state:
no error state collected

I can add more info.

1. I can not reproduce freeze if I stop lightdm and launch just xterm

startx /usr/bin/startx

Although when I switch between LVDS1 and VGA1

xrandr --output LVDS1 --off --output VGA1 --auto
xrandr --output VGA1 --off --output LVDS1 --auto

approximately in a half of cases I get blank screen. I can restore the image by switching to a console [Ctrl+Alt+F1] and back.
I do not see any errors in dmesg or Xorg.0.log

2. I have not managed to reproduce freeze in unity-2d when only xterm is running. The problem with blank screen persists. After several switching I have noticed

[drm:drm_mode_getfb] *ERROR* invalid framebuffer id

in dmesg output. More switching leads to more such lines.
At certain moment

xrandr --output VGA1 --off --output LVDS1 --auto

failed with the following error:
xrandr: cannot find crtc for output LVDS1

Nothing unusual in xrandr output:

xrandr
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 8192 x 8192

   640x480 75.0 60.0 59.9
   720x400 70.1

Surprisingly [Fn+F6] switched image to internal screen and xrandr started to work again.

I am afraid that some applications will be able to freeze X server even when unity-2d is running.

Status changed to 'Confirmed' because the bug affects multiple users.

[Paweł Stołowski (stolowski)]

I've similar problem when using xrandr to setup my laptop screen and external LG monitor (HDMI):
xrandr --output HDMI1 --primary --mode 1920x1080 --right-of LVDS1 --output LVDS1 --mode 1600x900

However in my case I'm experiencing hard freeze and am not able to switch to VT.

I have experienced this bug on my laptop with every version of Ubuntu since 11.04 at least (I'm not certain if it occurred in 10.10). For this reason I am still running 10.04 where it does not occur. It also happens in Kubuntu and in Fedora 17.

I have my laptop lugged into an external monitor via HDMI most of the time. The problem usually starts when I switch to just the external display, with the laptop screen off. Behaviour appears normal for a few second to a couple of minutes. Then the mouse and keyboard stop responding, and eventuall y the screen will flash and go dark.

Sometimes I am able to switch to a non-X terminal and do a soft restart. Other times I will not be able to do that and have to just power down.

My Xorg log is attached.

My background is Java not C, but I'm more than happy to try to provide extra info or run tests if that would be helpful.

The commit referenced in upstream bug 50078 has been included in an upload to precise-proposed, so once it's accepted there, please enable -proposed and test the package. Thanks!

[Adam Conrad (adconrad)]

Hello Max, or anyone else affected,

Accepted xserver-xorg-video-intel into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/xserver-xorg-video-intel/2:2.17.0-1ubuntu4.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Timo Aaltonen (tjaalton)]

closing for quantal, should be fixed there

[Timo Aaltonen (tjaalton)]

Hey, if you won't test the package from -proposed, the fix will have to be dropped, since there's another bug waiting for this one (bug 966744) that needs to get to -updates soon.

[naut (naut)]

This fix works for me

[Colin Watson (cjwatson)]

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regresssions.

This bug was fixed in the package xserver-xorg-video-intel - 2:2.17.0-1ubuntu4.2

---------------
xserver-xorg-video-intel (2:2.17.0-1ubuntu4.2) precise-proposed; urgency=low

  * Add 106-uxa-only-consider-attached-outputs-valid.patch, two upstream
    commits merged together that fix GPU hangs on resume, due to outputs
    getting marked valid before the kernel reports them attached.
    (LP: #992391)
  * Replace 101_copy-fb.patch with the patch that went upstream, backported
    to build against the older xserver. Needed for other backports.
    - refreshed patch 104 to apply.
  * Add 107-uxa-fix-pageflip-race.patch, fixes a race with pageflip and
    dpms, resulting in for instance compiz hanging. (LP: #966744)
    - consists of five upstream commits merged as one and backported to
      build against the xserver in precise
