I''ve been searching for a few days and I can''t find any reference for changes in configs on how to increase the graphical screen size of an installed and functioning vm. I''m running a fedora 6 install with a fedora 6 vm. If I edit the vm''s xorg.conf to include higher res settings and restart X, the config seems to revert back to the pre-edited version. If I go to the Sytem/Administration/Display settings and crank it up from 800x600 to the other available 1024x768 and restart X, I just get 800x600 again... Ideas??

Re: [Xen-users] Increasegraphical screen size of vm
Thanks Mats, I should have said that I''ve got a recent system- tons of vram and usually 1600x1200 works fine with other distos. I''ll look into the xorg.conf more carefully.
