Problem sa vesafb-tng i framebufferom

^{20.05.2006. u 20:20}

Imam sledeci problem -- iako je kernel (2.6.12) kompajliran sa podrskom za vesafb-tng, i uredno prosledjujem parametre u grub-u, i ocigledno se kreira odgovarajuci fb dev, ipak uvek zavrsim u 80x25 konzoli.

dmesg kaze:

Citat:

Gde gresim?!

BTW "vga" parametar je izostavljen, kao sto vesafb-tng dokumentacija i kaze... (naravno, probao sam i sa njim, ali rezultata nema)

Ajde daj malo vise informacija. Npr. koja je distribucija u pitanju, menu.lst(grub.conf)...

Distro je Gentoo Linux 2005.1. Kao sto rekoh kernel je 2.6.12 koji se dobija se distribucijom (tacnije 2.6.12-gentoo-r6 iz gentoo-sources), koji je vec patchovan sa vesafb-tng patchom.
Gore, iz dmesg loga, se vec vidi koji su parametri prosledjeni kernelu, ali evo bitnog dela iz grub.conf/menu.lst:

Citat:

title Gentoo Linux
root (hd0,6)
kernel /boot/bzImage root=/dev/hda7 video=vesafb:mtrr,ywrap,1024x768-16@85

Koliko vidim ti hoces samo framebuffer bez splash tema (livecd-2006.0 i slicno). To nisam bio pokusao da namestim, ali cu probati
cim predjem na drugi komp (na kome je gentoo).

Ok. Upravo sam probao i radi.
Kernel je gentoo-sources-2.6.16-r6, a verzija splashutils-a je 1.1.9.8-r1

U grub.conf-u je isto kao kod tebe:

Code:

title=Gentoo Linux splash.old
root (hd0,0)
kernel /2.6.16-gentoo-r6 root=/dev/hda3 video=vesafb:mtrr,ywrap,1280x1024-24@60

dmesg:

Ne bih znao kako da ti vise pomognem.

Skinuo sam vanilla 2.6.16 kernel, primenio vesafb-tng patch, i naravno sada sve radi.
Ostaje mi nejasno zasto nije radilo, ali ocigledno je da je problem u tome sto nije doslo do "switch-a" na framebuffer, odnosno u dmesg logu je nedostajalo:

Citat:

Console: switching to colour frame buffer device 160x64

nakon kreiranja framebuffera...
