imac g3 tried many xorg.conf configs... any more ideas?

g3 slot loading imac flower power
600mhz
640mb ram

I'm able to boot to yaboot and to my command line... but i cannot get X to start up. Im checking lightdm it doesnt seem to have any errors in the log. My xorg.0.log file is throwing errors for Bus error at a certain locatation [x0xx000000] for example.
It then says aborting x server signal 7 bus error.

I have tried inputting the specs for the imac based on other imac examples. i was able to log in and

sudo nano /home/lubuntu/xorg.conf.new

i edit my setting and hit ctrl+o to save file. I know its saving correctly. i checked the xorg.0.log to see what xorg.conf and it does use 'xorg.conf.new'

I even changed my yaboot parameters to add

radeon=modeset.0

and tried that...

I even tried booting using yaboot parameter

video=offb:off

and all that did was freeze on my open firmware screen before yaboot comes up.

Any ideas?? I reallly want to get lubuntu up and running.. my kids have projects to do for school coming up and i feel really bad that i cant get this thing runng... i dont want to try fedora..

Pretty sure everything you need is in the FAQ and Known Issues (it's the very first thing listed under 12.04) pages. So this is going to be brief.

Xorg that should work with the live CD (not saying it's the best setup and I've never used an iMac in my life):

Section "Device" 
     Identifier "Card0" 
     Driver "r128"       
     Option "UseFBDev" "False" 
     Option "NoInt10" "True"
     Option "ForcePCIMode" "True"        
EndSection

Section "Monitor"       
     Identifier "Monitor0"       
     HorizSync 58-62       
     VertRefresh 75-117 
EndSection

You put it in /etc/X11/xorg.conf . Not in your home directory.

/etc/X11/xorg.conf does not exist and i cant load /etc/X11/xorg.conf from that location... i'll have to try maybe i didnt capitalize the X? that would be sweet.

but yea... for some reason when i ran the install (see thread http://ubuntuforums.org/showthread.php?t=2117455) i was forced to manually partition the hd to make a separate /home partition. Only way i could get thru the base system install. So i have 4 partitions instead in of three.

apple/boot/swap/home

so i did notice that there may be a problem loading conf file from /home.

But what can i do about this? When i try the automatic partitioning, i get drive I/O errors and everything takes forever to boot up. I have never gotten into x on this machine.

I will try mixing and matching more options in the xorg.conf... but i'm tempted to try and get the live cd running to see if i can boot into X and get a graphical install going... i have spent hours on this issue.

[imacg3ppc]

back to the drawing boards.... going to try a fresh install and try to get a standard automatic partition table.. you guys/gals think that if i get rid of the /home mix up that i have a better chance of being able to boot into x?

if you try this

http://ubuntuforums.org/showthread.php?t=2090462

but use

live video=offb:off radeon.modeset=0 single

and

modprobe aty128fb mode_option=1024x768-16

can you get GUI then ?

[imacg3ppc]

i am going to try that tonight, first off the hd then on the live cd. Thanks so much for the tip great to have a helping hand(s) here in the forum and when i get up and running will reciprocate with any help i can provide.

Will update in the AM of 2/22.

Thanks again.

[imacg3ppc]

OK, so it's a no go. No matter what i cannot

startx

It does tell me no screen configured, but i have edited the xorg.conf many times over with various configurations. I'm going to try an install of straight up wheezy w/ lxde to see if it makes any difference... if anyone else has any ideas... let me know! and thanks for the help if i come up with a solution i will create a new thread with the details.

If I was a betting man I'd say you are not typing things right. Plus I suspect your frustration is stopping you reading the documentation properly and instead you are following the whacky advice on the internet.

At the yaboot prompt:

live single


Wait for root prompt.

sudo nano /etc/X11/xorg.conf

Type in what I wrote.

Save it

Then run

sudo start lightdm

If it still doesn't work then tell us the errors in

nano /var/log/Xorg.0.log

The proper way to set up an xorg.conf is in the FAQ.

i'll have to try it again, i really appreciate you guys checking back and all. I Did try the live cd and had it printed from the links i was given in this thread. I think i may be just overlooking something but I do want to try again.

I can't even put OS X back on this thing as i have no external hd and no install dvd lol so I'm determined to get this working. Thanks again and i'll let everyone know. Great community here. cheers.
