hi narcis garcia,
getting me this. don't know why overdrank closed other thread either! did complain mods overuse of power, didn't reopen it!
did see link posted later on thread too! it's been on list of things reply thread. i've been busy @ moment limited amount of time write on forum , many threads haven't been able answer.
haven't got r128 card, interest due guide wrote http://ubuntuforums.org/showpost.php...35&postcount=1 . wanted make sure advising people correctly. on askubuntu.com trying follow version of guide , totally failed r128!
user 'axion' did post interesting answer though http://askubuntu.com/questions/58488...on/62789#62789 .
compiling kernel seems bit extreme (and i'm not sure whether answer axion 100% accurate), particularly after read post 'walterav' on mintppc forum http://mintppc.org/forums/viewtopic....1&p=2673#p2673 . says method works on ubuntu 11.04 too:
i should point out has got thing yaboot.conf wrong. should edit file in /etc , use command ybin copy across boot partition. alternatively, if want test use @ second yaboot prompt:.... switching virtual consoles "ttys" have lower resolution working fine! haven't tried mintppc versions yet, pure debian 5 , ubuntu 11.04 mini. .....
second, real problem new kernel versions "offb" (openfirmware framebuffer) gets loaded first. therefor "aty128fb" not load (memory reserved error etc), , blacklisted, check syslog/dmesg , report framebuffer. fixed adding "video=offb:off" yaboot.conf in append section, btw file resides in boot partition not in /etc/. when restart have no framebuffer @ , won't see thing on screen, unless can login via ssh. before restart, uncomment aty128fb in /etc/modprobe/blacklist-framebuffer.conf. give framebuffer halfway past bootstrap modules loaded. don't panic if see openfirmware/yaboot screen freezing when system booting, wait , have picture back.
third thing fixed using "xorg.conf" found on website adding (option "usefbdev" "true"), because gonna use framebuffer "aty128fb" , selecting "r128" driver. therefor other maybe conflicting options "noint10" etc not necessary, these found options might necessary workaround if have no or conflicting framebuffers.
.....
it might best check first haven't got video=ofonly in yaboot.conf don't know how react new yaboot parameter.code:linux video=offb:off
thing has got wrong want comment line (by adding #) in /etc/modprobe/blacklist-framebuffer.conf rather uncommenting says.
if after reboot things successful, possibly load aty128fb framebuffer earlier in boot process running command "update-initramfs -u"?
possibly test these things @ second yaboot prompt typing:
option "usefbdev" "true" default setting on powerpc shouldn't have state in xorg.conf.code:linux video=offb:off modprobe aty128fb
interesting if of these things make difference experience of r128. when run "glxgears -info", if don't see "software rasterizer" written have 3d working think (but no expert on this). when run "glxinfo" check have @ start of output "direct rendering: yes".
finally, great see enthusiasm ubuntu , imac. keep work!
