Xorg.0.log

Hi, 

on the same notebook with windows xp the grapic performance is okay, but with the latest intel-driver under linux the performance is poor. if composite is turned on its MORE poor.

there is also a suspicious line in Xorg.0.log:

(II) intel(0): Primary V_BIOS segment is: 0xc000                         
(EE) intel(0): vm86() syscall generated signal 11.   

this is a bug, isnt it?

x11-driver-video-intel-2.4.2-4mdv2009.0
libxorg-x11-devel-7.3-4mdv2009.0
x11-server-xorg-1.4.2-7mdv2009.0
mesa-7.0.4-1mdv2009.0

thank you!

what do you mean by poor performance?
Comment 2 Eric Anholt 2008-10-03 13:32:27 UTC 
The vm86 call is gone, not that it should have been related to your bug.

To do anything, we're going to need sysprof output showing where in the X Server (presumably) CPU time is being spent during a specific activity you think the driver is slow it, and the desktop environment you're doing that activity under.
