controlfb working at 1024x768@60 Hz

controlfb working at 1024x768@60 Hz

[David Riley]

After several inquiries without answer, I decided to find out for myself
why controlfb always reverted to vmode 17 when I set it to 14 (even with
fbset).  Apparently, whenever the geometry is set to 1024x768, the
refresh rate is automatically set to 75 Hz.  I set the default value to
60 Hz instead, and now it works fine with my monitor (which doesn't do
75 Hz).  If anyone has a similar problem, there's your fix.  However,
controlfb still doesn't do kernel args (for what reason I can't fathom),
and having a default value for every resolution is not the right way to
go.  I, however, have no idea how to implement a more permanent solution
(i.e., it actually goes to vmode 14 when you set it there, and vmode 17
when you set it there).

Anyway, I'd include a patch for this if I knew how to use diff, but I
suppose you'll just have to find the spot yourself if you need to fix it.

Hope this helped,
	David

I hope this is the right list to post to about this, please correct me if
I'm wrong.
I recently got a 3Dfx Voodoo3 card, which works fine for linux, but I'd
like to be able to boot from OF instead of bootx.  I know that I have to
point the display to /bandit/3Dfx,Voodoo3 but this only gives me a res of
640x480 and vmode doesn't allow me to change it (if I boot from bootx I
can get my typical 1280x1024). I'm wondering if there are options to pass
or set in OF that will allow me to change the resolution.
the machine is an PM8600
thanks in advance
