I've installed Lubuntu 12.04 on a Powerbook G4 (PowerPC 1GHz, 1GB ram, Geforce MX 440). Everything works perfectly except the startup and shutdown. To startup my system I have to wait about 3 minutes (and similar time to shutdown)
Giving a look at
/var/log/dmesg I noticed the following
[drm] nouveau 0000:00:10.0: Detected an NV10 generation card (0x017900a5) checking generic (b8004000 151800) vs hw (b8000000 80000000) fb: conflicting fb hw usage nouveaufb vs 0Ffb NVDA,Displ - removing generic driver
The only issue concerns Nouveau: my
BUG: soft lockup - CPU#0 stuck for 22s!
I've booted passing the
nouveau.modeset=0 parameter and the system boot in 15 seconds but with 4 bit graphics -- Any idea how to fix?
