Public bug reported:
Binary package hint: xorg
Perhaps it is a xserver-xorg problem.
1. Live-CD: I can start the live-cd in vga-resolution-mode but not with
higher resolution. I can get higher resolution (ubuntu shows 1600x).
After restart the xserver with ctrl-alt-back leads to nothing. No chance
to start ubuntu.
2. Upgraded to 7.10: it's easy to start ubuntu, but only with the
800x640 screen resolution with the vesa-driver. Changing to the matrox
graphiccard is ok. But the monitor should stay as plug'n`play. Changing
to LCD 1280x1024 is ok only in the failsafe-mode. If i try to start
ubuntu in the gnome- or x-client-mode with the resolution of 1280x1024 i
will get the following result. After the password input the screen
changes to ubuntu-brown and then to black. After some seconds i will see
the start screen again. i can repeat this strange procedure. (Strange)
remark: The resolution of the start screen is 1280x1024.
The graficcard is an agp (4x) one with one monitor. On the Intel i815
motherboard is a second onboard graficcard, unused and less solution.
Best regards
Bernhard Schülke
