If you get to single-user with a boot (adding the " 1" in grub edit mode), alternate consoles will have some stuff of possible value. <CTRL>-<ALT>-<Fx> (where the Fx is function key F1, F2, F3, ...) should switch you to other screens. Also, <ALT>-<RIGHT> or <ALT>-<LEFT> can be used to cycle through. If X has not been started, the <CTRL> can be omitted from that first set I mentioned.
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. Looking at the alternate consoles while the config is running might be helpful.
If I run system-config-display in, saying tty1, it start successfully. 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?
Unfortunately not.
Try moving the mouse off the edge (Hmm. Is the mouse working during this process? I forgot to test that).
Mouse is working.
- Can you get/see what I described at all?
- If you can, and if you make and save changes, you should be able to
get to a graphical screen later. BUT FIRST ... 3) At a root prompt, type dmesg | less and look for any messages that might give clues. This might be useful regardless of the results of 2).
Also, there might be useful messages in /var/log/messages and /var/log/Xorg.*.
I don't know if I can post such heavy files here... This is a devel list, not a user one. Xorg.0.log is 38Kb and messages is 435Kb !
I don't recall what card you have - nvidia?
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.
