I'm running a Linux server without X11 or any kind of GUI, with a modern 22" LCD monitor.
Given the huge size of my monitor, I would like to increase the number of rows and columns in my console, how can I go about achieving it?

Add something like
"vga=792"
to the kernel line in yourgrub.conf
file, usually located in/etc
or/boot/grub
:You can say
vga=ask
instead to get a menu on boot, built from a probing process performed by the kernel to see which resolutions are likely to work. I find that there are often other numbers that will work that this method doesn't find.This is all system-specific. Different video cards will have different supported modes, and kernel build options can open up or close off video mode options. The subsystem that deals with this is called the kernel framebuffer, so if you're compiling custom kernels, be careful not to remove the support your kernel needs to fully support your video card. Most cards can use the VESA FB driver, but another driver specific to your brand of card might open more options.
Also, beware that some parts of this subsystem use hex numbers, and others decimal. You can do the conversion to decimal, as I've done, or you can say something like
"vga=0x318"
instead.
