Dear Ubuntu Geeks,

Ubuntu screen resolution is not coming above 800*600.

I use a 17 inch monitor and I want the resolution to be 1280 * 1024

Can you let me know how should I do this. I have checked the resolution part, and it has maximum of 800*600 only.

Thanks in advance

1) Which graphics card brand/model number do you have?
2) Did you enable all restricted drivers using System > Administration > Hardware drivers?
3) Post the output of these commands (Applications > Accessories > Terminal):


cat /etc/X11/xorg.conf
lspci


P.S. Ewww, light blue colour.. :p

Warning: Follow this at your own risk!
1) Do this command:


sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.test
sudo dpkg-reconfigure -phigh xserver-xorg
2) Reboot your computer
3) Log in normally
Note: If there's an error and you can't login normally and you get a console/terminal, login from the console and execute:

sudo cp /etc/X11/xorg.conf.test /etc/X11/xorg.conf
sudo /etc/init.d/gdm restart
Let me know if you had this error.
4) Go to System > Administration > Hardware drivers and tick/check to download and enable all the necessary drivers.
5) Reboot your computer once it is done installing
6) Login and execute this command:

gksu nvidia-settings
7) Do you see "X server display configuration" in the nvidia-settings window? If not, please let me know.
8) You can choose your resolution and monitor model from there.
9) When you're done setting up your monitor, press "Save to X configuration file" and reboot once more.

It should be fixed :)

Hi,

The issue got resolved. I booted through Recovery mode and did x-Server fix. Went to System->Preferences->Main Menu->Others->Screens and Graphics

Added the same to Main menu

From Main menu, I just chose my Dell Monitor and I was able to modify the resolution to 1280*1024

Thanks for all your help.
