Re: [opensuse] video problem with an ancient laptop [SOLVED]

I will disable modeset and reboot.

What's your kernel line now that you have it working?

Mmm... I see you use "vga=791" in the kernel line. I might try that, too.

The kernel or Grub Legacy observes that initially, but if KMS is not disabled, then EDID will tell kernel the mode to use and, unless there is a match, a mode switch will shortly follow text messages display. All this is without Plymouth. I don't every use it so don't know how it plays together with these parameters.

Bingo! That does it, vga=791. I thought we were to use display=...

That may be something Grub2 uses, but it does absolutely nothing here with Grub. If you want to tell KMS the mode you want in openSUSE, it's video= that takes the place of vga=. Maybe with yours, display= removal was the actual solution. Most of my systems are started using video=1152x864 along with vga=791 or vga=794, but 1152x864 and 794 put a native 1024x768 LCD into sleep mode.

instead, that's why I did not even try vga=...

Removing vga= from kernel line has no effect here.
