Re: Debian 8 on Late 2005 G5, Graphics Issues



That's what I did. Have lxde running, seems to be doing pretty good, idling ~8% and 323MB.

Use LXDE or XFCE. They are much more lightweight and you will have a better experience.

That actually worked. It's REALLY slow in software rendering though, might have to install kde or something :(

Thanks,

On my dual core G5, I have to disable hardware acceleration when using

nouveau driver by adding this to my yaboot parameters.
nouveau.noaccel=1

If that works, you'll want to add this to your /etc/yaboot.conf file as
the
last line under your default kernel (probably named Linux) as well to
make
it permanent.
append="nouveau.noaccel=1"

Save those changes, and then run "sudo ybin -v" to apply those changes.

I'm currently trying to get 3D acceleration working again on the
nouveau
driver by compiling the latest drivers directly from Nouveau's git
repository and using a later kernel. Unfortunately, I'm getting a GPU
locked up message at boot, which causes my system to fall back to the
fbdev
driver, but that's an issue for another email on the Debian PowerPC
mailing
list and possibly a bug report to the nouveau maintainers.

Trying to run Debian 8 Jessie -official Powerpc
Chose Cinnamon on Install

I have installed Jessie but it boots to a scrambled black and white
screen.
I can get into terminal from this screen and work there just fine
except
for a constant "isochronous cycle too long" error, but I think that
is a
different issue.

Have tried "nomodeset" at boot. It gets me to a black screen with a
purplish cursor.

Wheezy worked fine, no problems and worked perfect right from install
so
Im guessing if I could roll back to whatever Wheezy had for X/Nouveau
(or
whatever runs the graphics), I might be able to get this working.

I'm a noob and looking for some steps to take, Id really like to get
Jessie working if possible.

Ive asked about this in a couple different places and didn't get much
help.
