ti powerbook g4 1ghz 15"

[ssam]

made X11 (espcially opengl stuff like screensavers) much faster by editing /etc/X11/XF86Config

changed

Code: Select all

Driver "fbdev"

to

Code: Select all

Driver "radeon"

and

Code: Select all

#Load    "dri"

to

Code: Select all

Load    "dri"

then logout and restart X (ctrl-alt-del at the login screen) or restart the whole machine.

run glxgrears -info to get frames per second before and after if you want to compare.

backup your XF86Config before you mess with it

I have a 1Ghz Powerbook Ti, 15" as well - but the ydl installer won't work in graphic mode or text mode - only text-safe mode.. Then, when I get it all installed and try to make X work, I keep getting signal 11 errors..

I have tweaked everything I can think of - no luck.

Can someone who has successfully gotten X working on a system like mine, please post their XF86Config file? Thanks!

did you try running the X autoconfig utility and leaving the setting as thier defaults to just get it up and running and then change 1 setting at a time

my /etc/XF*^Config for a titanium powerbook 15" 1Ghz

beware, i have fiddled with the mouse bit to try and get all the buttons working on a logitech mx500, but not had much luck.

The default install of YDL didnt provide 3D and enabling DRI only improved things a little. I followed the instructions here without any luck, but the instructions did start me experimenting with a few things. In the end I used the settings above but switched "radeon" for "ati" and I've now got 3D. I'm not sure this fix has been posted before, I AM a true linux newbie and I havent fully tested the fix apart from Chromium and 3D screen-savers, so I could be talking to the converted ... or much wiser. I'm not sure.

The only glitch I do get is after selecting a 3D screen-saver, and testing it, I get a square of inverted colour on the screen (random location). BUT, this does disappear after I open a command prompt. No problems in running Chromium, screen returns as normal. Oh, and when X starts the switch from pure CLI to X is distorted for a second, but comes good and gives me the usual (not distorted) login screen.

I hope I havent wasted time here.

Just an update, I tried this fix on the iBook after updating to Yellow Dog 4.0 (2.6.9-1.ydl. and it doesnt work. Screen fails after running "glxgears". Still got a few things to try though. I havent installed any 3D app's or games, so I really cant say for sure, but the frame-rate in glxgears seems acceptable... not much load in glxgears though.
