Trouble setting Open Firmware Framebuffer resolution
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
I recently wrote a Mail to the list with the same problem and just tried
a couple of things which weren't successful:
1. I tried to set open firmware resolution with fbset -g 1024 768 1024
768 x - no success. The -verbose option tells me, set everythings worked
fine - but it didn't. I read that setting the resolution wouldn't be
successful, but that source was from 2001 and so I estimated the problem
had been fixed. Is that true? Or shall I use another way to set the
video mode.
2. It seems that the Linux Kernel sets the resolution of the OF FB from
1600x1200 to 1280x1024, which means he is definitly able to do so. But
when I pass arguments like "video=mode:1024x768-8@60" to the kernel, it
just ignores them regardless of the form ( I tried "1024x768",
"mode:1024x768" ). I don't find Documentation about OF FB on the net
neither in the /usr/src/linux/Documentation - so please tell me, where
to start my research.
3. I tried to change resolution in "ok Prompt" of my machine. I read
that on macs ( which aren't too similiar to RS6000 machines ) it runs
like that:
"dev screen
~ show-modes
~ set-mode xxx"
But neither show-modes nur set-mode is known and ls tells me, I'm in an
empty directory ( pwd tells me /screen ). Is there a way like that to
change the display resolution in OK prompt? Might another graphics
adaptor solve the problems?
I know these are a lot of questions but I'm totally helpless and I need
at least a hint to make my machine at least a bit more useful ( at the
moment it's totally useless for me ). If you have a hint or at least an
idea please, please write me and tell it. I've got lots of time to try out.
Many thanks in advance
Philipp Vollmer
