I am trying to use a 24" external monitor as the primary monitor for my Asus EEE netbook. When I connect it, it works properly, except the max resolution available is 1024x768. Usually, I'd go into the xorg.conf and add it, but 10.10 doesn't seem to have an xorg.conf. I read on another question here that I could simply go into recovery mode and make one using X -configure and moving the new xorg.conf into /X11/ but that caused X to not even start. I renamed xorg.conf to a temp name for now.
What should I be trying? Thanks!
Type:
cvt 1280 1024 60
Will see something like:
Modeline "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
Copy this line except for the Modeline part
Pass this copied text to xrandr --newmode like this:
xrandr --newmode "1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
Add the new mode to the proper device (in my case, VGA1. Find this via xrandr)
xrandr --addmode VGA1 "1280x1024_60.00"
You will now see the new resolution on the resolution options.
