Description:

Upgraded from xf86-video-intel 2.11.0-2 to 2.12.0-1, and my dual monitor setup stopped working properly. Even though the primary monitor is fine, I get a black screen in the secondary monitor, although you can move the mouse pointer into it and see it, but you can't freely move it all over the secondary monitor, because the mouse is bounded to a small portion of it.

Also, even though I have a setup of secondary monitor to the right of primary, xrandr strangely reports that the current resolution is 1280x2048, instead of the normal 2560x1024.

Additional info:

No xorg.conf used.

Same problem at my workstation. I reverted to 2.10 to get my 2nd screen working again, I haven't had time to bisect the regression yet.

Same problem for me after the upgrade of xf86-video-intel

After driver update xrandr doesn't work as expected. Native resolution is not supported
anymore. And the second screen is not really detache.

>> xrandr --output VGA1 --pos 1024x0 --mode 1280x1024 --rate 75.0
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 149 (RANDR)
Minor opcode of failed request: 7 (RRSetScreenSize)
Serial number of failed request: 26
Current serial number in output stream: 27

so I have to :
xrandr --output VGA1 --pos 1024x0 --mode 1024x768

>> xrandr

I have 965 and dual monitors seem to be working fine. Maybe just a problem with 945?

After trying to use xrandr to extend my desktop to the second monitor, the X server outputs this message:
> (EE) intel(0): Failed to allocate framebuffer.

I can confirm the bug on Intel 945GME, bug exists on 32-bit architecture as well.
Comment by Juri (lynucs) - Monday, 02 August 2010, 08:48 GMT
confirming the same issue with:

00:00.0 Host bridge: Intel Corporation Mobile 915GM/PM/GMS/910GML Express Processor to DRAM Controller (rev 03)
00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)

This is actually a bug in libdrm:
http://cgit.freedesktop.org/mesa/drm/commit/?id=726210f87d558d558022f35bc8c839e798a19f0c

The new intel driver uses libdrm to allocate framebuffer, which doesn't work on pre-965 hardware without that commit.
Comment by Jan de Groot (JGC) - Monday, 02 August 2010, 20:59 GMT
This should be fixed with libdrm 2.4.21-2.
