I'm not quite sure if my bug is the same as reported here, but I let others decide.  

To begin with, when I start my computer, the monitor goes off soon after the grub menu and comes back on just before the login screen. This happens with the live CD too, and prevents me from checking the installation CD for defects (the checking seems to happen, but I'm not able to see the result). The problem was present already on my earlier Gutsy installation (started perhaps two weeks ago), but I thought it might be because of the experiments I had made with the Nvidia driver (from the Nvidia web site). The monitor doesn't cause the problem, because I tried with another one and got same behaviour.

This is a step by step description of my observations after the installation was finished:

Login screen refresh rate was at 60 Hz and the screen was vertically stretched (not exceeding the screen edges).

Desktop resolution was at 1280 x 768, which means that the desktop was vertically stretched (my monitor being a regular 21" CRT). Refresh rate was 60 Hz.

Graphics card was detected right ("NVIDIA Geforce 8800 Series").

The monitor was not detected. The description was "Custom 1".

I changed monitor model to "Sony GDM-f500/f500t9", which allowed me to select a resolution of 1400 x 1050 and a refresh rate of 85 Hz in "Screen and graphics preferences". A message "All users must log out for changes to take effect" (my translation from Finnish) appeared. I closed the message window to take notes. When I re-opened it, all resolution options above 1280 x 1024 had disappeared. The only available refresh rate was 60 Hz. The selection I made for the monitor ("Sony GDM-f500/f500t9") was still there. I selected the resolution 1280 x 960, which worked at 60Hz refresh rate.

Next I logged out. After logging back in and opening "Screen and graphics preferences", nothing had changed, except that 85 Hz was added as a second option for refresh rate (so now there were 60 Hz and 85 Hz). I selected 85 Hz and it worked. Still no resolutions available above 1280 x 1024.

I decided to reboot and see what that would do. The desktop resolution changed from 1280 x 960 to 1280 x 768 and the refresh rate to 60 Hz (the option for 85 Hz disappeared) without my intervention (other than rebooting). The long list of available resolutions came back though, and I tried to select 1400 x 1050. The resolution changed to something else than that. I would guess 1280 x 1024, because ther were black margins on the right and left edges of the screen, but the desktop wasn't malformed (the "Screen and graphics preferences" and "Screen resolution" kept showing 1400 x 1050). Now the refresh rate option of 85 Hz was back again, and I selected it to see what would happen. It worked and the screen resolution went to 1400 x 1050, which it was supposed to be.

Next I rebooted again to see if things would be stable now. Unfortunately not. The resolution was back in 1280 x 768 (vertically stretched) and refresh rate at 60 Hz (the only option). Here I thought that it's time to make a bug report :-) Well, I had to log out once more to change the system language to English to find the right names for the settings windows. When I logged back in, the resolution was 1920 x 1200 and refresh rate 73 Hz (60 Hz being the only other option). My monitor is not a wide screen model. I made one more try for 1600 x 1200 @ 85Hz, which is one of the settings on the modelines, but that didn't work. And this is where I am now.

I didn't have these problems with the nv driver on my Tribe 5 installation.
