Še ene stranpoti sem se spomnil
X-i znajo za prikaz uporabiti tudi t.i. framebuffer device, ki je pod
nadzorstvom samega jedra, v tvojem primeru linuxa. Strojni gonilniki za
framebuffer device so v /lib/modules/2.6.11-1-686/kernel/drivers/video
(verzijo nadomesti s svojo). Zate sta bržkone zanimiva samo intelfb in
i810fb. modinfo pravi takole:
# modinfo intelfb

Torej... če ti uspe naložiti kateregakoli od njiju ('modprobe i810fb'
ali 'modprobe intelfb') in dobiš konzolo v grafičnem načinu, potem si na
konju. V /etc/X11/xorg.conf (ali /etc/X11/XF86Config-4) popravi gonilnik
iz karkoli že pač imaš (vesa, i810) na fbdev (Driver "FBDev"). Pomaga
tudi 'man fbdev'. Framebuffer device je sicer nepospešen, vendar ga imam
na sumu, da dela bolje in hitreje kot pa vesa. Poskusi, morda ti uspe.

U.
