If I start up in single user mode, I get only one console. No switch possible. So I start in run-level 3. > Once you are at the root prompt, do the system-config-display with no > parameters.

If I switch to tty2, then back to tty1, I don't see the system-config-display dialog any more, just the command I typed before. > If the system finds _any_ driver it can use - e.g. vga, svga, vesa - it > should bring up a graphical screen that has a computer icon and some > tabs for display, multi-head, etc. There's a couple drop-down menus that > let you select resolution, color depth, etc. Unfortunately, resolution is too low (320x200), so, I can't see the "Cancel" and "Valid" or "OK" button of the system-config-display dialog. > Select something not too "heavy" and save the settings and exit. > > If only part of the screen is visible, maybe the screen is scrollable?

VGA compatible controller: ATI Technologies Inc M71 [Mobility Radeon X2100] (rev ce) (prog-if 00 [VGA controller]) I think now it's a X server problem as it can't compute modelines for vga module. I get, in Xorg.0.log, many lines as: (II) VGA(0): Not using default mode "320x240" (insufficient memory for mode) Lines differs in mode value (II) VGA(0): Not using default mode "1920x1200" (insufficient memory for mode) I know that the 1920x1200 mode is doable.
