I have a Riva128 based video card in a older SMP P-Pro system and with all
of the lastest 2.4 series of kernels (mostly the ac stuff) I have screwy colors
on the console (the penguin boot logos are shades of blue) and initially when
I start X (XFree86 4.0.3) the colors are very dark until I switch to a console
and back again. Once I switch to a console and back to X things are fine in
X. I noticed a reply to a note from Louis Garcia <[EMAIL PROTECTED]> by
Bakonyi Ferenc <[EMAIL PROTECTED]> with some info about TNT cards
expecting 8 bit verses 6 bit color registers. Bakonyi indicated that the console
colors should be correct with Rivafb 0.9.2 and above but with the 2.4.5-ac3
kernel the boot messages indicate:
rivafb: RIVA MTRR set to ON
Console: switching to colour frame buffer device 160x64
rivafb: PCI nVidia NV3 framebuffer ver 0.9.2a (RIVA-128, 4MB @ 0xEF000000)
My /proc/pci entry says:
Bus 0, device 15, function 0:
VGA compatible controller: NVidia / SGS Thomson (Joint Venture) Riva128 (rev 16).
IRQ 19.
Master Capable. Latency=64. Min Gnt=3.Max Lat=1.
Non-prefetchable 32 bit memory at 0xee000000 [0xeeffffff].
Prefetchable 32 bit memory at 0xef000000 [0xefffffff].
and even at 0.9.2a colors are still screwy on the console both before and after
starting
the Xserver.
The fbset output on this system says:
mode "1280x1024-74"
# D: 135.007 MHz, H: 78.859 kHz, V: 74.116 Hz
geometry 1280 1024 1280 1024 16
timings 7407 256 32 34 3 144 3
accel true
rgba 5/11,6/5,5/0,0/0
endmode
The same thing still occurs if I set the color depth to 8 bit.
This is a pci card with 4Mb of video memory. I also have a AMD K6 system with a 16Mb
AGP TNT2 card and this does not happen on that machine.
BTW, why is the mtrr for the Riva set to 0M ???
