[SOLVED] Dell XPS 15 Intel video problems

Hi,

Basically I'd like to hear if owners of the Dell XPS 15 L502X laptops experience similar problems with Intel video as I do.

I keep seeing all kinds of flickering all over the place, it's not very dominant but annoying. Most of the time it's triggered by mouseovers,
for example if I hover over a link, then move the mouse away the highlighting remains there until i hover over it a few times more.
Progressbars flicker too, for example in Sonata. Buttons in gtk apps become black sometimes.
The Eclipse IDE is especially susceptible to this.

If you don't experience these bugs could you show what Intel video driver packages you are using, that would be helpful (libgl, xf86-video-intel and anything else that might be related).
Thanks

I don't own that hardware, so I cannot add any observations.  Have you combed through your /var/log/Xorg.0,log to verify that all of the hardware acceleration, DRM modes are functioning? Does glxinfo show you are using hardware rendering and that there are no serious limitations?

Direct rendering works, CS in wine works, World of Padman has decent FPS, so does Warsow, and they don't have any defects in graphics.
glxgears shows ~1800fps.

Do you have Nvidia card in this notebook? If yes, do you use some scripts for optimus to work (for example http://www.martin-juhl.dk/2011/05/optim … em-solved/ or disabling discrete card?

I disable it.

Update:
I reverted all the testing packages that I had, and it still is the same.

For those interested in a workaround, Option "Shadow" "true" in xorg.conf solves this (although you are left with no 2D acceleration and other inconveniences), best bet is to wait for newer Intel drivers, currently there's a lot of work happening on the Sandy Bridge stuff.
I'll probably file a proper bug report when I have more time (exams are killing me).

Re: [SOLVED] Dell XPS 15 Intel video problems

I've installed the linux-git package which currently contains the upcoming 3.1 kernel which now contains a good portion of drm patches and they seem to have solved all of my problems completely.
Thought I should mention this here.

I guess this is solved.
