issues with screen resolution

[civillian]

After I installed 8.10 (fresh install from linux format cover-disc) and installing the nvidia drivers for my GeForce 8400 from ubuntu restricted driver manager (and then updating from proposed updates as suggested on another forum) I am stuck with a resolution of 1024x768, which is a step down from my monitors full resolution of 1280x1024 (the monitor is an LG Flatron L1718S)

My xorg.conf is as follows

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 1.0  (buildd@palmer)  Mon Nov  3 08:46:46 UTC 2008

EndSection

and the output of xrandr - is

   400x300        58.0  
   320x240        59.0

Any suggestions would be welcome!

I had a similar problem getting 1920x1200@60hz, I used the nvidia-settings (had to upgrade nvidia drivers to 180.16 to get it to work as it kept segfaulting when i saved to xorg.conf with it) and it added this to my screen section.. maybe you can modify it to your settings...

Option         "metamodes" "1920x1200_60 +0+0"

[civillian]

how do I find out what version of the drivers I have installed?

[XsCode]

180.16 are the latest beta drivers and not available via apt I don't think...

you can check the version with nvidia-settings

[civillian]

I'm using the 177.82 drivers (reccomended by restricted drivers manager)...how would I go about upgrading them to the beta 180.16?

[XsCode]

32bit are here

64Bit are here

you may want to print this bit out...

1. Make sure you have build-essential installed
2. in a terminal type
   

   sudo /etc/init.d/gdm stop

   This will drop you to the command line.
3. log in
4. type (if you downloaded the driver to your home folder, otherwise cd to wherever you put it)
   

   sudo sh ./NVIDIA-Linux-x86-180.16-pkg1.run

5. follow the instructions
6. when you get back to the command line type
   

   sudo /etc/init.d/gdm start

you should now be running on 180.16

nvidia settings will have moved to Applications -> System Tools

Thanks, I'll try doing that, adding the line

Option         "metamodes" "1280x1024_60 +0+0"

although I'm not sure about the refresh rate (its 50 atm but it may be 60 at the higher resolution?)

and I'll post results.

Thanks for help!

I did what you suggested and now I have the latest nvidia driver, and my xorg.conf looks like this

# nvidia-xconfig:  version 1.0  (buildmeister@builder57)  Fri Dec 12 13:13:55 PST 2008

I tried adding

Option         "metamodes" "1280x1024_60 +0+0"

but it crashed the xserver when I reloaded it so I had to remove it. I can get a resolution of 1152x864 but its still a bit small

Can anyone make any more suggestions?

[XsCode]

try adding this line to the monitor section in xorg.conf then restarting xorg

modeline "1280x1024@75" 135.0 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync

P.S. Happy Birthday for next week

[civillian]

Thanks (for both)!
Do I need to add the line as

modeline "1280x1024@75" 135.0 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync

or

option modeline "1280x1024@75" 135.0 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync

?
