The max resolution available is 800 x 600. How can I make it higher?

I recently had to fix a relevant problem regarding the login screen that was incorrectly sized.

Quoting from problem 31625 - worked for me, but I don't claim any special knowledge - YMMV
Don't want to insult you, but don't know your expertise - gedit is the graphic editor. The command they provide is entered at the terminal window to give you admin priviledges.

Hi Kris,

I had the same problem. The solution for me was this:

Press Alt+F2 and enter:
gksudo gedit /etc/X11/xorg.conf

Scroll down to the Screen section and add the following lines:
        SubSection "Display"
             Depth 24
             Virtual 1024 768
        EndSubSection

Change 1027 768 to your resolution

You should get something like this:

Section "Screen"
        Identifier "Default Screen"
        Monitor "Configured Monitor"
        Device "Configured Video Device"
        SubSection "Display"
             Depth 24
             Virtual 1024 768
        EndSubSection
EndSection

Try the following. Maybe it helps.

1: Copy the file /etc/X11/xorg.conf to /etc/X11/xorg.conf.bak
2: In a Terminal enter sudo gedit /etc/X11/xorg.conf
3: Have a look at the screen section (the sub section is important)

Section "Screen"
 Identifier "Default Screen"
 Device "nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro]"
 Monitor "Generic Monitor"
 DefaultDepth 24
        SubSection "Display"
                   Modes "1280x800"
        EndSubSection
EndSection

4: Save the file
5: Restart the system

Hope it helps.

Hello

I have a new sony vaio laptop : model VPC EB 46 FG, with Intel core i5 processor, 4 GB RAM, 500 GB hard Disk and windows 7 home premium Operating System. It has ATI Mobility Radeon HD 5650 graphics card. Its screen resolution is 1366x768 (high definition), that is functioning perfectly all right in windows 7.

I have created two virtual machines. On one virtual machine, I have installed windows XP professional and MS Office 2003, it is running very nice, screen resolution in virtual windows XP is functioning perfectly all right, that is - 1366x768.

On the second virtual machine I have installed ubuntu 11.04. But in this mode, the biggest screen resolution available is 800x600 only. Other four screen resolutions available in the System > Preferences > Monitors are – 640x480, 680x384, 512x384, 400x300 which are much smaller. I have been examining various web-site, forums, blogs, and tried large number of permutations and combinations, upgrades and installed various solutions but nothing has given the desired screen resolution of 1366x 768. Can anyone suggest the correct solution for getting desired screen resolution of 1366x 768 in Ubuntu mode also.
