Summary: [radeon] KMS (and X.org) detect wrong outputs Product: Drivers Version: 2.5 Kernel Version: 3.1-rc3 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: niels_ole@salscheider-online.de Regression: No
On my notebook, 6520G (mobile A6 APU), KMS detects a screen on VGA-0 although there is no attached. Because of that it chooses a lower resolution than the internal display's native resolution. The selected mode causes the internal display to flicker, though.
In dmesg, I can see the following:
[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [drm:atom_execute_table_locked] *ERROR* atombios stuck executing E3E6 (len 2585, WS 4, PS 4) @ 0xEAD0
Other issues I have with this : - xrandr reports a size of 0x0 inches for the internal display - the internal display uses only 6 bit/pixel and there seems to be no way to enable dithering - the brightness controls do not work although there is a sysfs acpi interface that gets updated - the display does not come back on after standby
These issues may be unrelated and I will create further bug reports if so, but maybe they give a hint concerning this issue.

--- Comment #4 from Niels Ole Salscheider niels_ole@salscheider-online.de 2011-08-29 12:44:23 --- When I run rmmod radeon and insmod radeon after standby via ssh the screen stays black, too.
It seems that the radeon module cannot find any edid information at all.
Is there anything I can do to debug this further?

note: radeon_fp_native_mode gets calld for LVDS although get-edid can find valid edid data for it (see next attachment)
