Hi,
I have a laptop with Intel chipset:
00:02.0 VGA compatible controller: Intel Corporation Mobile
945GM/GMS/940GML Express Integrated Graphics Controller (rev 03)
I'm using Ubuntu with unofficial Intel driver version 2.0.0-1feisty1.
xorg.conf is almost without any options, only "Virtual 2048 2048" is there.
I've connected external LCD (via VGA) and TV and can't get them to work
simultanously with built-in display.
xrandr shows:
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 2048 x 2048
VGA connected (normal left inverted right)
1280x1024 60.0 + 75.0 59.9
1152x864 75.0
1024x768 74.9 75.1 60.0
832x624 74.6
800x600 75.0 74.9 60.3
640x480 75.0 74.8 60.0
720x400 70.1
LVDS connected 1440x900+0+0 (normal left inverted right) 303mm x 190mm
1440x900 60.0*+ 50.0
1280x800 60.0
1280x768 60.0
1024x768 60.0
800x600 60.3
640x480 60.0 59.9
TV connected (normal left inverted right)
1024x768 30.0
800x600 30.0
848x480 30.0
640x480 30.0
I can enable LVDS+VGA or LVDS+TV or VGA+TV. But when I have enabled
two of them, enabling third do not work:
(when LVDS and VGA are active)
% xrandr --output TV --preferred
xrandr: cannot find crtc for output TV
(xrandr --auto yields same result).
When LVDS and TV are active, messages says "xrandr: cannot find crtc for
output VGA". Is this fixed in later version of driver?
