Thinkpad can't switch video out between internal screen of the laptop and VGA output. It was working fine in xorg 6.8.x and stopped working in xorg 7.x. In both cases, the xorg own radeon driver is used. Normally, the thinkpad ACPI module allows to switch between laptop LCS and VGA out.
Please post your xorg.conf and your xorg.log

Try Option "BIOSHotkeys".

It's correctly placed. I suppose turning it off doesn't make a difference?

Does switching work on the console? Make sure the thinkpad apci module is configured correctly (you might also test without it loaded). It can be configured to generate acpi events for things like the video toggle button rather than letting the bios handle it.

When I press switch monitor button - it doesn't generate any events. Sleep, lid, power buttons work fine - events are generated and processed. I've also tried to use "ati" driver instead of "radeon" (in xorg.conf).
I'm seeing an issue like this, but I'm not sure if it's the same one. Plugging a projector in video-out results in no image on the external projector. "radeontool dac on" has no effect. Restarting the X server (logging out or <ctrl><alt><bksp>) results in a display, but the resolution is borked (low-res and stretched vertically). In that mode xrandr reports: # xrandr SZ: Pixels Physical Refresh *0 848 x 480 ( 287mm x 163mm ) *-25880 Current rotation - normal Current reflection - none Rotations possible - normal Reflections possible - none xrandr cannot change resolutions in that mode. Am I seeing the same bug, or should I open a different one? BTW, This is a Thinkpad T41. I use the radeonfb driver in the kernel. I need it to make suspend power down the graphics card. I don't have BIOShotkeys enabled. It used to work for me too.

(In reply to comment #11) > You problem looks like bug 7243. Thanks. On further investigation, I think it looks like 7203.
Looks like bug #2000 too. Reporter, please mark this one as dupe.
