Bug#783381: upgrade from wheezy to jessie on a PowerMac G4 Silver/Confirmation
Package: upgrade-reports, linux-image-3.16.0-4-powerpc
Followup-For: Bug #783381
Hi,
> And now to the graphics problems :-(
on my system, I could improve the situation by replacing GDM3 with Lightdm, and
Gnome3 with the Awesome or Fluxbox window manager (since they actually started
and displayed something, which was not the case with GDM or Gnome, they just
displayed an error along the lines of "something went wrong", with a logout
button). However, I then got some kind of crash/lockup when I executed eg.
dmesg in an xterm (mouse pointer still visible/movable, but otherwise, nothing
changed, and restarting X iirc just got me a black screen with mouse pointer).
I could improve that by adding
append="radeon.agpmode=-1"
to the yaboot config of the kernel I'm booting, which disables AGP mode, but so
far seems to result in a stable system (I have the feeling that it feels slower
on certain UI updates though, but I'm not sure about his). So far, I've found
some bug reports [1,2,3] which might be related to these issues, but haven't
tried anything further.
Still don't have working suspend to disk/ram though, but that could actually be
related to the graphics issues and/or my workaround.
Kind regards
Manfred
