Bug Description

Binary package hint: xserver-xorg-video-intel

If I switch to an X VT (either by switching to a console VT and then back, or by starting a "guest session") then screen goes black (but the backlight is still on).

This happens on Ubuntu Jaunty (updated a few hours ago) when using the UXA as the AccelMethod. When using EXA everything works fine.

Setting status to confirmed. However, it has recently been decided that Jaunty will be shipped without UXA because of issues like this, so this will bug will get a low priority in Ubuntu for the moment. We would encourage you to forward this bug upstream, so that UXA will be more stable in the future. See http://intellinuxgraphics.org/how_to_report_bug.html .

Using Linux 2.6.29-rc5, X.org Intel 2.6.1, with UXA, sometimes rendering appears to hang. The cursor is still moves, but there is no update to the icon. There appears to be no other response. The following is reported in association with the above problems:
[drm:i915_get_vblank_counter] *ERROR* trying to get vblank count for disabled pipe 0
It does not appear that the modeset parameter to the Linux module i915 affects this. My hardware identifies itself thus:

I've just tried using linux 2.6.29-rc6 and am still experiencing the problem.

Further, I can most easily reproduce the failure by having mode setting enabled on boot, with gdm starting up. I logging in to Gnome happens successfully but on rendering any new window, things lock up as described. I.e., starting an application, a popup window from a panel applet, but not the panel window itself, oddly.

Never. I was not reporting this specifically as a regression; just another data point.

I confirm this bug on i915 - Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)

linux-2.6.29-rc6; libdrm master (ad64ff30d0e85486bba8fb6f0e2fcb1caa06fd5c); mesa-intel-2008-q4; xorg-server-1.6.0; xf86-video-intel master (38a7683561cee7fffab174c2a166bfd51b51ba27)

VT switching -including sleep/hibernate- and x11perf triggers the issue for me, 'normal' 2D desktop usage doesn't.

I continue to have this using:

intel driver 2.6.2/2.6.3
mesa 7.3
libdrm 2.4.5
xorg 7.4
kernel 2.6.29-rc7-git1

the system locks on vt change on 2.6.2, and locks aftter kdm login in 2.6.3

This still appears to be present on rc7, though it seems to trigger more consistently now (:)); still associated with window creation or application startup.

Which x11perf setting were being used, as I can't seem to trigger it with a default invocation?

On x11perf 1.2 aa10text and shmput500 tests triggered the bug, although I didn't try other tests.

I notice that you are using version 2.6.1 of the driver, whereas we are shipping 2.6.3, which has a number of fixes especially for UXA. Please re-test against the Jaunty release and let us know if this is still an issue.

I'm finding it hard not to reproduce this bug on my laptop atm! Wobbling wobbly windows in compiz a lot usually causes it. I've recorded the whole of /sys/kernel/debug/dri (I hope you dont mind that it's tarred), and dmesg. I have the result of intel_gpu_dump but it's big and I'm not sure how useful it would be, so havent posted it.

I have exactly the same graphics card, i945, I'm using:
ubuntu 9.04

Nevermind, I see you've already done that testing on the upstreamed bug.
