Text resolution for text-only modes needs to be modified.
This document (3796470) is provided subject to the disclaimer at the end of this document.
SUSE Linux Enterprise Server 10
The text-only modes can be seen at the following times:
During system boot and shutdown the process can be viewed in text mode by pressing Esc (if the splash screen is being displayed).
Six Virtual Terminals (text-only) are available by pressing Ctrl-Alt-F1 through F6.
If the system is brought up in runlevel 3 it will be text-only, no graphic interface.
The modification of this parameter does not effect the resolution used for graphic modes (I.E. GNOME and KDE desktop environments).
You will find the configuration files for GRUB and LILO in the following locations:
As you review these files you will see the selections and the kernel load line for each which will look something like:
kernel /boot/vmlinuz-188.8.131.52-0.2.5-smp root=/dev/sda5 vga=0x31a resume=/dev/sda1 splash=silent showopts
Just modify the "vga=0x31a" (or whatever is listed) to a value that is appropriate based on the table below.
To use YaST just open YaST from the menu and select "System" on the left and "Boot Loader" on the right. Once in the Boot Loader configuration highlight the selection you want to modify and click the "Edit" button near the bottom.
At the bottom of the edit screen you will see a selection for "Vga Mode". Change the value to something appropriate and save your changes.
A reboot of the system is required for the new setting to take effect.
Here is the list of available settings based on the documentation provided with the kernel. This document can be found at"/usr/src/linux/Documentation/fb/vesafb.txt".
