What graphics card do you have? Do you have the correct driver installed? Can I suggest you run 'lspci' and make sure that your graphics card is seen by Linux. You could also look into /var/log/Xorg.0.log and see what X is doing on startup. One thing I like to try is to stop gdm/lightdm whatever, and then run startx. If it fails it often gives a helpful message. -- Philip Stubbs -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
