View Full Version : [ubuntu] oneiric and ATI Mobility Radeon HD 5400/4200 : no hdmi out

November 1st, 2011, 08:17 PM
I have these cards on my laptop:

01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200]
02:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5400 Series] (rev ff)
but hdmi out doesn't work, the tv says "no signal"; with windows 7 it works out of the box.

I installed flgrx provided by official repo and I also tried to install a more recent version using the .run file provided by AMD, the hdmi monitor (tv) isn't listed in monitor settings and neither in catalyst control center.

xrandr gives the following :

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 1600 x 1600
LVDS connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm
1366x768 60.0*+
1280x768 60.0 +
1280x720 60.0 +
1024x768 60.0 +
1280x600 60.0 +
1024x600 60.0 +
800x600 60.0 +
800x480 60.0 +
640x480 60.0 +
CRT1 disconnected (normal left inverted right x axis y axis)
as you can see it lists only modes for internal monitor and CRT1 which is (I think) the display of VGA out.

Any hope to get hdmi video out working ?
