View Full Version : [gnome] monitor configuration lost on every logout

February 9th, 2009, 02:42 PM
distro: ubuntu 8.10 amd64
dual monitor:
- lg flatron 995ft plus on the left, 19'' 1280x1024@85 Hz
- lg flatron f900p on the right, 19'' 1280x1024@100 Hz
video card: ati radeon 9800 pro, using open source drivers (not fglrx)

I've set up all perfectly using gnome-display-properties (and a little tweak of the xorg.conf file to get 100 Hz refresh), but every time I reboot or simply log out, all is messed up (mirror screens, wrong vertical refresh etc.).

This is my xorg.conf, with the 100 Hz modification, but even before that modification the settings didn't used to be saved.

I honestly don't know where to look to resolv this problem, also thanks to the fact that every time I put a line in xorg.conf I don't even know if Xorg cares or not about that...

Please try to suggest solutions that don't involve the installation of fglrx, because gaining a good multimonitor with my hardware and that driver is IMPOSSIBLE... The actual configuration that I had is just perfect, it only needs to be SAVED... somewhere...

Sorry for my english, and thanks in advance...
