With Slackware 12.1, KDE 3.5.9, NVIDIA GeForce 7300 GS, a recent Linux version nvidia driver installed, and nvidia-xconfig was ran, the LCD screen resolution will not stay set to the maximum or native of 1280 x 1024, it will default back to 1024 x 768. In my xorg.conf file it lists modes only up to that 1024x768, but I did try to add that 1280x1024 by manual edit of the xorg.conf, but on a restart it just hung on starting X11 session manager, so I then went back to use the backup xorg.conf. When I select either the auto or 1280 x 1024 resolution in the nvidia x server settings configuration tool, it says on the bottom; "using metamode 1280x1024", but when I start the computer the next day, it goes back to 1024x768 on my Dell 1704 FPT LCD monitor. What can be the solution for this display issue ?

This is now fixed.

What did you do to resolve the problem?

I fixed this by increasing the horizontal sync to a value closer to my Dell LCD actual specifications, and added in the 1280x1024 to the modes lines, thanks. I did have a issue with editing the xorg.conf file with the konsole terminal as root, it was telling me this; "cannot connect to X server", so I had to log in the computer as the root user to do this. In the terminal I entered; su -l , for root, which should work, right?

Usually i just do:

su -

then enter my root password.

Glad to hear you got your problem sorted.

Regards.
The trooper.
