I'm using Ubuntu 12.10 with an ATI Radeon HD5670 card.
I currently have the open source xorg-edgers driver. I've been using this driver interchangeably with the Radeon open source driver since fglrx seems to give me a lot of freezes. So I can't really use proprietary drivers, the Radeon driver seems to be stable for me, the resolution is the only problem.
The resolution is stuck at 1024x768, where my monitor's native resolution is 1366x768. How do I enable that resolution? Going to System Settings > Display only gives me 800x600 and 1024x768 by the way.
And just another question, how do I know if xorg-edgers driver is enabled? When I run sudo lshw -c video
, I still see the radeon driver.
configuration: driver=radeon latency=0
Thanks a lot in advance!
UPDATE:
Running xrandr
gave me this:
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
..
DVI-0 connected 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
So following the guide, I typed in the following:
cvt 1366 768 60
xrandr --newmode "1366x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync
xrandr now gives me this line:
1366x768_60.00 (0x178) 85.2MHz
But I'm still not able to execute the add command xrandr --add-mode DVI-0 1366x768
, it just shows me the usage page for xrandr.
