I've got a new installation on Compaq 6715b. I tried following these instructions to increase my screen's resolution.
What I did:
Ran the command:
sudo cvt 1680 1080 60
Found out my device like this:
And I got this:
Screen 0: minimum 320 x 200, current 1280 x 800, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS connected primary 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1280x800 60.0*+ 1280x720 59.9 1152x768 59.8 1024x768 59.9 800x600 59.9 848x480 59.7 720x480 59.7 640x480 59.4 S-video disconnected (normal left inverted right x axis y axis)
Then I typed this:
sudo xrandr --newmode "1680x1080_60.00" 151.50 1680 1792 1968 2256 1080 1083 1093 1120 -hsync +vsync
And then did this:
sudo xrandr --addmode LVDS 1680x1080_60.00
Finally, I got to the GUI and took display settings. I changed the resolution and my screen went crazy. Just one flat colour with no components. Only a few random squares.
I've searched and the task seems pretty challenging to me.
Is there an easy way to fix this?
