Bug 21352

What's the intel driver version? It will be good if you could try 2.7.0, which fixes a similar issue.

Please refer to http://intellinuxgraphics.org/how_to_report_bug.html and attach Xorg.0.log.

Xorg.0.log

There is my Xorg.0.log.

Driver 2.7.0 I cannot use because isn't in Gentoo repository.

Xorg.0.log with DebugMode

I want to tell that new Xorg is quite slow. I don't remember my FPS in old Xorg (1.3.*) but there is about 57 FPS. I see it by 3D effect (in fluxbox I use 3ddesktop application to switch between desktops and it is too slow).

I found that 57 FPS is quite normal so I'm sorry.

Does all your reported problems happen only when you set virtual "3200 1080" in xorg.conf? But your Xorg.0.log doesn't show Virtual set.

Sorry, I have commented line with virtual resolution. I create new Xorg.0.log and paste it here (in 1 hour, I cannot restart X now).

Xorg.0.log with DebugMode and Virtual line

There is required Xorg.0.log. Now I have connect external LCD (1920x1080). 

I have to tell that if I have open firefox and I want to scroll down (any web page) it's horribly slow. With this it is impossible work.

Xorg.0.log with Virtual line and AccelMethod=UXA


If I add to Section Device this options:
Option      "DRI"           "true"
Option      "AccelMethod"   "UXA"

Than I cannot run XDM. XDM is starting and my LCD on laptop is blinking. After a ew minutes it stops and I see console.

So your chipset is 945, that means you lose DRI if setting Virtual > 2048 pixels. (bug#10479, probably won't be fixed in near future)

With DRI disabled, there are some known issues:
bug#19578: VT->X broken.
bug#21060: playing video broken in 2.6.x driver, fixed in 2.7.0.
expected slow.

Does this explain the problems you are seeing?

Before bug#10479 resolved, maybe you can use the workaround for layout the dual monitors as top-down so it fits within 2048x2048.

And if you want to use UXA, better use xserver 1.6.x.
