I have just installed Mandriva on a desktop with a nVidia card:
03:00.0 VGA compatible controller: nVidia Corporation NV44 [GeForce 6200 LE] (rev a1)
And today I was messing about with the fonts, as they are a bit blurry, and checking nVidia Display Settings I saw the resolution was set to 1280x720, same with System - Preferences - Screen Resolution, but drakconf showed the resolution to be 1366x768 (the correct one). Just to be sure, I took a screenshot and checked, it was 1280x720. I found that strange, so I thought I had to change xorg.conf, but cat /etc/X11/xorg.conf | grep Mode gave me this:
So clearly xorg.conf is correct, but the Screen Resolution utility does not allow me to increase the resolution above 1280x720. Could it be limitation in with hardware? If so, strange, I ran the max resolution on this screen with a much older Intel card. And I seem to remember that this same card allowed me to run it at 1366x769 in Windooze.
Running Mandriva 2008 Spring (Powerpack), currently in GNOME but I have KDE installed as well, and running Compiz. Will check if I get the correct resolution in KDE, but I would prefer it to be correct in GNOME as well...
