Description David Balažic 2001-02-21 10:20:49 EST
All redhat 7.1 betas , upto and including Fisher, fail to set up
the framebuffer device during install (from CD ) on my system,
which has a nVidia GeForce2MX based gfx card.
The GUI install is done by the classic X server, so it is not
a big problem.

I tested the rivafb 0.9.2 driver in recent kernels ( 2.4.1-ac10 )
and it works on this hardware. I used fbset to set different modes
on the console and it worked. I didn't try any gfx program though.

We don't use HW-specific framebuffers for the install, only vesafb.
Comment 2 Michael Fulbright 2001-02-21 17:52:23 EST
Please attach output from lspci and lspci -n.

For the record my GeForce 2 MX works in framebuffer.
Comment 3 David Balažic 2001-02-22 05:25:52 EST
Fisher uses the vga=787 kernel command line parameter.
That mode ( 787 == 0x313 ) does not work on my GF2MX
788 works and gives , according to the kernel message 800x600x16

dmesg :
vesafb: framebuffer at 0xd8000000, mapped to 0xd0800000, size 32768k
vesafb: mode is 800x600x16, linelength=1600, pages=3
vesafb: protected mode interface info at c000:0ed1
vesafb: scrolling: redraw
vesafb: directcolor: size=0:5:6:5, shift=0:11:5:0
Console: switching to colour frame buffer device 100x37
fb0: VESA VGA frame buffer device

Great -  we have corrected the default mode to be 788.
