I'm setting up an AMD Sempron box with Kubuntu 6.10. I am using an old Daewoo monitor. I changed the screen resolution from something high (1200 x something) to a more useable (on this monitor) 800 x 600. I also chose the monitor from the manufacturer list. It all seemed OK and popped up a message to restart the X-server to use the new settings. I did a reboot (didn't notice the "restart X" option in the login/out menu) and now when I try to login I just get dumped back to the login screen. I can login as any other user and everything works fine, it's just that my personal login was the one which (in Kubuntu) has the su option.
I can login to a shell and can su from there but I don't know what I need to do to restore the screen resolution for my account to something which will work. I presume there is a file which I can edit to fix this but I don't know which file. If there is a log file which would be useful for diagnosis please tell me and I'll put the contents here.
Instead of booting from hard disk boot from the linux 1st cd and then edit
In that file change the entry for Screen0
U will find "1200*968" "800*600" "640*480"
now remove "1200*968" and save it.
OK; I've bitten the bullet and done a reinstall. Screen has installed at 1024 x 768 so I'll just accept that and not fiddle. Thanks anyway, I now know more about configuration than I did previously so your answers wern't wasted. Thanks again
Cheers
Ian
Just press the Ctrl, Alt, and '+' keys simultaneously to scroll through the various resolutions in your xorg.conf file. (Note that the '+' key refers to the + key on the numeric keypad, not the +/= key adjacent to the Backspace key)
