I have a Red Hat Fedora installation that was setup with the incorrect screen resolution. My ATI Mach64 (whoohoo) card is easily capable of 1024x768. I made the mistake (?) of selecting a Generic screen of that resolution. The GUI login screen comes up as an incomprehensible fluttering screen as though the horizontal hold was way, way off! I tried CTRL-X to go to character mode to no avail - I'm currently at the Linux rescue prompt to try to figure out how to change the resolution to 800x600, or force the system to boot into character. I did an update install as well, forcing 800x600 and it still looks like the horizontal hold is busted - can't see anything like it's in an opposite interlace mode. Any experience or ideas are greatly appreciated! Robert Achmann.
