I have an NVidia card at work. I've been using the NVidia driver from
NVidia's web site< and it's worked well.
If you have a working X server whose only problem is the display
resoution the simplest approach is probably just the hack the
- get out of X, as you have done
- take a copy of the current xorg.conf
- edit the original
There should be a section called "Screen", with a subsection called
"Display". Edit the "Modes line to include the resoution you want;
it must be something your monitor and card are supposed to do.
Here's an example clause form my laptop:
Viewport 0 0
Modes "1400x1050" "800x600" "640x480"
I run in 1400x1050 on this machine.
- start a new X server
You can just run the command "startx :1", which will commence a new
X server using id ":1" (because :0 is in use by the "main" X server
just at present).
If this works, you will get a display, probably not running your
normal session. But we are only testing the resolution, so that's
ok. If that's good, we're ready; quit the X server by typing
ctrl-alt-backspace. Then return to your main server (Alt-F7)
and quit it (ctrl-alt-backspace); this should cause it to start a
new server using your new settings.
If not, examine the file /var/log/Xorg.1.log. It should show
the driver trying various resolutions. Search for yours.
For example, for my laptop I would search for 1400x1050.
The driver will only use a resolution it believes that
the card will do and the monitor will accept.
If the above procedure works, you're good to go. Otherwise, there are
more things to try.

need is a bunch of unregulated, amateur squids running loose.
