I’ve just spent quite some time configuring a laptop to give out a higher screen resolution for an external monitor. I wanted to use the laptop with an external screen, eyboard and mouse (well trackball but you know what I mean). Anyway after some hours and rather a large number of re-boots I finally got it to work.
I edited the xorg.conf file and added additional resolutions – I did this several times without effect until I restarted the machine and then shut the lid whilst the computer was booting up and this finally allowed a higher screen resolution to be selectable in the screen resolution applet….
This should really be easier… anyway for reference here is the xorg.conf, changes for each Mode where it used to say:
Modes "1024x768"It now says
Modes "1280x1024" "1024x768" "800x600"
