Display Corruption under X - ibook2 G3 800 12"

[Zippy]

I have a problem with my 12" ibook2 (2usb G3 800)
(Ill apologise right now for this long post!)
I added append="video=ofonly" to yaboot.conf

This fixed the inital display when booting.

Ive tried the ebuild here https://forums.gentoo.org/viewtopic.php?t=28170
, and couldnt get it to work - I followed the instructions

So I ran Xeasyconf and got X running.....However I get problems with display corruption under X. (Lots of banding and "rolling" lines) Oh and CTRL-ALT-Backspace cause teh screen to show random patterns and flashes.

Kernel is 2.4.20-r1 on Xfree 4.3.2, or even 4.2.1 :p

Please Help, this is driving me nuts!!!

Heres my XF86config-4: (Again, sorry for the long post!)

You need to update your kernel.

rsync -avz rsync.penguinppc.org::linux-2.4-benh benh_kernel

Hi,

I had a similar Problem after installing the dri-trunk.
I just changed the VertRefresh to 50-70

section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 30-85
VertRefresh 50-70
EndSection

Well, I tried changing the refresh rates....updates xfree to 4.2.1-r2,
and rsync -avz rsync.penguinppc.org::linux-2.4-benh benh_kernel give me socket errors. mmm.** in progress*** - figured the problem


lol! nothing is straight forward is it!

[Gerk]

using video=ofonly is the problem, you have to use the native framebuffer drivers and not the open firmware

[Zippy]

IT WORKS!

Many thanks guys.
The combination of the new kernel and removing the video=ofonly from yaboot.conf has worked a treat.

Again, thanks
