Summary: [radeon KMS] switching to res 1024x768 kills output Product: DRI Version: DRI CVS Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: liquid.a...@gmx.net Created an attachment (id=33401) --> (http://bugs.freedesktop.org/attachment.cgi?id=33401) dmesg output Hi there, switching to resolution 1024x768 doesn't work on my hardware (RV740 + IBM P260 CRT), the CRT simply fails to receive a signal and shuts down. xrandr output: Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 8192 x 8192 DVI-0 disconnected (normal left inverted right x axis y axis) DIN disconnected (normal left inverted right x axis y axis) DVI-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 388mm x 291mm 1280x1024 85.0*+ 75.0 1600x1200 85.0 1024x768 85.0 75.1 70.1 60.0 960x529 75.0 800x600 85.1 72.2 75.0 60.3 56.2 640x480 85.0 72.8 75.0 60.0 720x400 87.8 70.1 1280x1024 is the standard mode and I just tried it: Every other mode works completly fine - just the 1024x768 mode results in no signal. No interesting output in dmesg when switching via xrandr. Kernel is uptodate drm-linux branch of airlied's tree. But this also happens with drm-radeon-testing. Not sure if it's a KMS problem, but at least it happens with KMS enabled. I can try a testrun with modeset disabled, if that helps.
