vesafb conflicts with sisfb

ugenn · 01-02-2004, 12:16 PM

My system boots up in framebuffer mode (vga=0x301 passed to kernel on boot) which uses the static vesafb driver. Problem is, I can't get my sisfb driver module to load since vesafb is active and has reserved the video mem for itself. Is there a way which I can disable vesafb?

to disable fb, change /etc/lilo.conf :
vga=normal
and don't forget to run lilo ^^

here's a site that deals with sis, fb and 3D acceleration on such in detail ->

yes, you can't use sisfb and vesafb at the same time....I guess there's no way to get around recompiling the kernel ^^
poor guy....I can remember how much trouble I had with a stupid sis630 chipset =(

thx, i've knew abt that site. great site. guess i'll just have to settle for vanillla vga (no more colourful penguin logo

)

don't give up...
recompile your kernel, throw out vesa, and keep SIS in framebuffer options.....
the appropriate append string should probably be

append="video=sisfb:mode:1024x768x16,mem:12288"

I got framebuffer working without much trouble...the ony real pain was 3D support ^^

of course remove that vga=normal line again =P

i haven't tried that kernel argument, but i believe it only works if sisfb is compiled statically which is not a feasible option for me because my base kernel needs to be shared on 8 other machines using a variety of different display hardware (and no, I'm not going to compile for 8 machines). i think i can live without the logo.
