[Lost Logic]

Hi all you smart folk.
    I've been trying to use the rivafb driver for my console, because I 
like 1024x768 console resolution, but dislike the slowness of the vesa 
framebuffer.  Every time I start X and then switch to a text console, it 
begins to mess up (my cursor turns into 2 purple dots) and if I try to 
switch back to X the console is completely corrupted, forcing me to 
reboot.  Is there a conflict that makes it incorrect to use a 
framebuffer text console and a different accelerated X console?  Or is 
this a bug in the memory handling of the rivafb that makes it conflict 
with the NVidia accelerated stuff, OR can I not ask this here, because 
I'm using the unlicensed NVidia kernel drivers?

Thanks!

Hi:

        I've the same problem. It's seems like a conflict of the nvidia drivers
and rivafb. Try to unload the nvidia_kernel module and use in X the nv
driver who comes with the X, that works (at least with my GForce2 Pro), but if
you do this, you'll loose the nvidia hardware acceleration...

Hi...
The rivafb and the nvidia-accelerated drivers conflict, yes, but you can own situation if you tell X to use the rivafb-framebuffer instead the nvidia-one.

Section "Device"
        Identifier      "GeForce"
        Driver          "nvidia"
        BusID           "1:0:0"
        Option          "UseFBDev"      "true"
EndSection

This should fix the problem.

And, I have my own question, too... How do I switch my resolution?

"kernel /boot/gentoo-2.4.20-r5-bo.nvidia root=/dev/hda3 video=rivafb:1280x1024-32@100" doesn't work for me.
What is wrong? 

Thanks a lot for solutions,

Not a surprise there :-(

This  works out most problems between X and fbdev.

Bug in the software. I need to fix that. Right now  I'm working on its 
hardware cursor which is messed up.
