I wanted to improve the resolution of the console on a linux server. After reading some forums and HOWTO’s I found out that it’s very easy, you just have to add
vga=MODEto your kernel parameters – where MODE stands for the desired screen resolution.The possible screen resolultions are listet here. These values are hexadecimal so
vga=791stands for 1024×768 and 16 Bit Colors (0×317).
