iBook 800 Mhz xorg help

servobf · Apprentice Joined: 03 Jun 2004 Posts: 160

I just reinstalled gentoo on my iBook, and I'm trying to get xorg set up for the first time. xorgconfg leaves my screen with a bunch of horizontal lines on the right 2 inches of the screen, and flickers on the rest of it.

I'd really like to get graphics acceleration going with my ati radeon 7500, but will settle for a working xorg.conf, if anyone can help me.

Thanks,

~Michael

I should have mentioned:
I'm using the 2.6.7 kernel. If you have a working 800 Mhz dual USB iBook, stating which kernel options were complied in, or modules would be nice (DRI, Radeon, etc.). Posting your working xorg.conf would also be handy.

thanks,

Michael

I just finshed installing and configuring X.Org on my 1Ghz G4 IBook running a 2.6.7 kernel too. Check out this thread relating to it. The main thing is to just make sure you got the right drivers compiled in your kernel.

If you want a head start, here is mine for a G3 900 iBook.

Have you loaded the module? Try 'modprobe radeon'.

I've loaded both the uninorth-agp and radeon modules (one first, then the other, and vice-versa) - the screen still has the lines on it, and I still get about 80 fps with glxgears

I don't know *exactly* what I did to get it to work...but it works. My kernel config file and xorg.conf file are at:

for anyone who wants to see them.

UseFBDev is the key here... I had the same problems, but I fixed it by using the fbdev driver directly. (As far as I can tell, opengl doesn't work anyway, so...)

So I was trying to get bootsplash working, recompiled the kernel a few times, tried X and got weird blackness with a huge flickery blue pointer, and a black background.
/var/log/Xorg.0.log said that it couldn't find /dev/fb2 or fb(3,4,5,6,7,8,9).

So, I'm trying to compile the kernel again. You mentioned a fbdev driver. What do I need to include to get that?

I have as modules:
ATI Radeon display support (Old driver)
ATI Radeon displayu support
Virtual Frame Buffer support
Framebuffer Console support
/dev/agpgart (AGP Support)
Apple UniNorth AGP support
ATI Radeon

Compiled in (only option):
Open Firmware frame buffer device support
Direct Rendering Manager (XFree86 4.1.0 and higher DRI support

Am I missing something? (kernel 2.6.7-pegasos)

Thanks,

Michael

I run xorg on an 800mhz G4 iBook with no issue. I'll put links to my configs for you to look at.

Note: I use gentoo-development sources. I also use bootsplash, to do that I followed the bootsplash guide but removed the gentoo-dev sources bootsplash patch and applied the one from the bootsplash site (I believe the second or third comment on the bootsplash 9 step guide sticky has the directions to do this).

Kernel config
xorg.conf

If you need any more info let me know.

Edit: The fourth comment on the bootsplash guide by DiskBreaker is what I did to get bootsplash functioning on gentoo-dev-sources.

I don't have bootsplash working yet, but X is working again. GLX gears gets arround 500-600 fps...so I guess that's as good as I'll get.

Thanks for your help!

That sounds about right for your hardware.

Thanks protosub. That was a typo in the file that I swiped and I didn't catch it. For some reason it still worked for me.

Unfortunately, my iBook is disassembled for painting right now. I've changed the file on my server and will try it on the iBook when it's back up and running.

I'm trying to get Xorg working on my fresh install on an iBook 800Mhz 15".

I've got kernel linux-2.6.7-gentoo-r14 (gentoo-dev-sources).

I did Xorg -configure, and it seemed to be ok...except it said it couldn't find fbdev and
(EE) RADEON(0): Cannot read V_BIOS (5)

I can run X and startx, but, comes up with all the flickering lines I've seen described.

My driver in my config file is "ati". I've tried it with "radeon" and it gives the exact same results.

I compiled in everything in the kernel, not modules...is this required as modules? I deselected ATI Radeon display support (Old driver) as an option...used the new driver...

I pretty much think I have all the rest compiled in....as described in the posts I've searched out so far...

Any ideas where to start looking?

TIA,

Cayenne

Are most of you compiling the video into the kernel or as modules?

Ps: Also, I'm seeing may of ya'lls xorg config files listing modelines such as:
