I am having the command line resolution of 1280x1024 in my home server (Squeeze). But my graphics card can only go up to 1024x768. I was succeeded in changing the resolution for my GRUB2 but this didn’t help me out. I also tried to install the X and also the GNOME just to verify that they work at 1024x768. Currently my system
In the kernel line of the /boot/grub/menu.lst file, you need to add the parameters. You can see the VGA table for the reference. In the Linux Video Mode you can check this table out. But the resolution that my system supports is only of the 1280x1024. So I changed the resolution by adding the value of the vga= 793 in the last of the kernel line. So just need to add the value that you want in the vga, by referencing the table.
To configure the command line resolution, you need to configure your xorg.cofig file. To do so you need to type:
ps - chris the file /etc/X11/xorg.conf
When you open this file you will find the following line in it:
Depth 1
Modes "1280x960" "1024x768"
Once when you open and see this file, you can find out these lines and understand that where you need to enter the values.
There is a simple way to change the resolution of your command line, you just need to enter the values of the vga that you want according to the resolution. I.e. vga=”value value” from the parameter in the command line that is there in your grub.config file. You can also do this by editing during the boot time. You can find various resolution values for it, you can check the resolution table manually.
If you can try this using the text mode then you can do the following steps that will help you out to change the resolution of your command line. For that you need to edit your /boot/grub/menu.lst. You can edit this file using any of the text editors you are having. I use the vim for editing
