Description krsengr 2011-06-20 18:37:17 UTC
(forgive me, I'm new at Linux) ISSUE: -- Dell Latitude D505 with 855GM graphics -- Loaded Open SuSE 11.4 w/KDE -- Desktop looks fine but windows flicker badly or disappear when apps are opened or doing alt-tab. Switching to another desktop and back stabilizes things a bit. -- Colors fine, resolution fine. Window flickers make driver unusable. TROUBLESHOOTING STEPS -- Reloaded again, used GNOME. Same problem. -- Checked SuSE release notes, altered many many settings. -- Tried Intellegacy driver, didn't work at all. -- Tried VESA driver (640x480), worked OK. -- Tried building driver myself from xf86-video-intel-2.15.0. -- Poorly built driver gave some errors, but worked the exact same way. SOLUTION -- Loaded SuSE 11.2, and graphics work great, no issues.Working module output from Xorg.0.log : Loading /usr/lib/xorg/modules//drivers/intel_drv.so (II) Module intel: vendor="X.Org Foundation" compiled for 1.6.5, module version = 2.9.1 Module class: X.Org Video Driver ABI class: X.Org Video Driver, version 5.0 Hope this helps!

I've just picked up a Latitude D400, and don't see anything too terrible on upstream drivers, yet. But then again I have yet to install KDE on it. Can you please attach the Xorg.log for the OpenSuSe packages and for your hand built driver?

Sorry, I lost all the old log files when I loaded Open SuSe 11.2.

Created attachment 50878 [details] Xorg log file when error occurs This is from the opensuse LIVE DVD 11.4 with KDE. THe error will also appear in GNOME. I have other log files if needed. Sorry for the delay in getting these.

This issue is affecting a hardware component which is not being actively worked on anymore. Moving the assignee to the dri-devel list as contact, to give this issue a better coverage.

Judging from the problem description, this is the 8xx pageflipping bug. Should be fixed in 3.5: commit c2798b19bac2538393fc932bfbe59807a4734b3e Author: Chris Wilson <email@example.com> Date: Sun Apr 22 21:13:57 2012 +0100 drm/i915: i8xx interrupt handler gen2 hardware has some significant differences from the other interrupt routines that were glossed over and then forgotten about in the transition to KMS. Such as - 16bit IIR - PendingFlip status bit This patch reintroduces a handler specifically for gen2 for the purpose of handling pageflips correctly, simplifying code in the process. v2: Also fixup ring get/put irq to only access 16bit registers (Daniel) Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=24202 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=41793 Signed-off-by: Chris Wilson <firstname.lastname@example.org>
