    Default Changing the framebuffer/CLI ressolution

    Hie,

    I use the CLI a lot (the C+S+F1-F6 terminals), but i have a really tiny resolution on the framebuffer. How do i increase the framebuffer/CLI resolution in suse (that is opensuse 11.4)??

    Any help would be great, oh and btw opensuse 11.4 is just fabulous !!!

    Well, some time ago I'd say you only have to change the vga= option in the boot options, but there's so many video drivers being used during boot that I'm not sure anymore.

    FWIW the vga codes are (or were):

    VGA Resolution Codes for GRUB & Lilo
    Code:

    Width-Height-Depth VGA Codes HEX Codes
    80x25 (TEXT) 3840 0xF00
    80x50 (TEXT) 3841 0xF01
    80x43 (TEXT) 3842 0xF02
    80x28 (TEXT) 3843 0xF03
    80x30 (TEXT) 3845 0xF05
    80x34 (TEXT) 3846 0xF06
    80x60 (TEXT) 3847 0xF07

    1600x1200x24 799 0x375

    8bit = 256 colors
    16bit = 65K colors
    24bit = 16.7M colors
    In this computer the code used is 0x31A.

    Edit: just noticed that, at least in 11.3, in Yast>bootloader>edit there is a drop-down menu listing the available resolutions.
