I am trying to change the resolution of my screen currently 1920x1440, billions of colors, on a Fedora Core 1, XFree.4.3,
to 800x600 to be able to watch .avi files on my TV screen and plug my thinkpad onto a videoprojector.
I tried several times by changing the convenient "modes" lines in /etc/X11/XF86Config but to no avail.
The KDE pretends to be in 800x600 mode but the it isn't true by evidence.
Any hint ?
