Increase the Virtual Console Resolution

The virtual console normally displays only 80x24 lines. To increase its resolution, edit /boot/grub/grub.conf and add vga=“resolution code” to the kernel line. The example sets the virtual console to 1024×768 and 24-bit color.

kernel /vmlinuz-2.6.18-92.1.18.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=792

See the following table for resolution codes.

Depth     800×600       1024×768     1152×864     1280×1024     1600×1200
8 bit       vga=771        vga=773       vga=353       vga=775       vga=796
16 bit      vga=788        vga=791       vga=355      vga=794       vga=798
24 bit      vga=789        vga=792       -------        vga=795       vga=799

P.S. This does not work with the Xen kernel.
