i have kinda problem with setting my resolution on ubuntu 10.04
the thing is that i installed the machine and put it away without mouse, keyboard and monitor (i am currently remote with VNC viewer)
now the problem is that without a monitor plugged in i can`t increase the screen resolution above 800×600
how can i increase it let`s say to 1024×768

If the mode doesn't yet exist, you'll need to create it first by specifying a modeline:
You may create a modeline using the gtf or cvt utility. For example, if you want to add a mode with resolution 800x600 at 60 Hz, you can enter the following command: (The output is shown following.)
Then copy the information after the word "Modeline" into the xrandr command:
After the mode is entered, it needs to be added to the output using the --addmode command as explained above.
