Using Yast to configure the bootloader Grub2.
The list of VGA modes contains only these LOW screen resolutions.
320x200 | 320x240 | 320x400 | 640x400 | 640x480 | 800x600 | |
---|---|---|---|---|---|---|
8bit | 0x330 | 0x334 | 0x331 | 0x300 | 0x301 | 0x303 |
16bit | 0x30e | 0x335 | 0x332 | 0x33d | 0x311 | 0x314 |
24bit | 0x30f | 0x336 | 0x333 | 0x33e | 0x312 | 0x315 |

Are there not any higher resolutions than 1600x1200x24 in VGA Mode? Why am I not getting these higher resolution vga modes in Yast bootloader configuration?
Setting VGA mode to 0x31F gives me a better console resolution: I have to write the Hex only, because writing “1600x1200, 24bits (modus 0x31F)” does not work.
