I recently installed ubuntu 8.04 on an external hardrive from which I boot from at bios instead of making a partition on my internal harddisk. It detected the intel video card and CRT monitor of my home desktop just fine. I brought the external drive to a friends house and booted it up using his Nvidia video card and LCD monitor where it was also working well. However when I brought the drive back home and attempted to boot up ubuntu it no longer correctly identifies my home monitor resolution restricting me to either 640x480 or 800x600. I tried editing and restoring an old xorg.conf using sudo gedit xorg.conf but that doesnt work either. So any ideas anyone?
