Description Damjan Georgievski 2008-10-30 05:55:56 UTC

Using ArchLinux (the testing repository)
xf86-video-intel 2.5.0
libdrm 2.4.0
xorg-server 1.5.2
intel-dri 7.2
mesa 7.2
libgl 7.2
kernel 2.6.26.7
(in ArchLinux most of these things are vanilla or very close to vanilla)

The problem:
when the driver is set to use EXA and I try to get a dual-screen setup (xrandr --output VGA --mode 1024x768 --right-of LVDS) I get cloned output, but the X server thinks (and shows info) that it has dual screen. For example, mouse and keyboard input are separate for both screens.

xf86-video-intel 2.4.2 didn't have this issue.

Switching to XAA corrects this (but then XV + compositing doesn't work).

Please attach your Xorg.0.log and xorg.conf, according to http://www.intellinuxgraphics.org/how_to_report_bug.html.

did you bother to click that url you posted?!?

Comment 3 Damjan Georgievski 2008-10-31 08:36:01 UTC

I don't have the 2.5.0 setup now, so I can't post the Xlog file.

I need my laptop in working condition now, and can't run tests on it more.

Sorry, the site seems to have some problem now. Please use http://intellinuxgraphics.org/how_to_report_bug.html instead for now.

Damjan, please attach the additional info from the bug reporting how to when you get a chance, otherwise it will be hard to track down this bug.

Comment 6 Damjan Georgievski 2008-11-12 13:07:42 UTC

It seems that I can reproduce this problem, but now I have:
libdrm 2.4.1 and xorg-server 1.5.3 and a self-compiled 2.5.0 of the intel driver.

oops, sorry... *can't* reproduce it now.. I'll save the logs when it happens again.

Ok, thanks.  Please re-open if you see it again (sounded pretty weird, I know tons of people successfully doing dual-screen independent configs).
