I'm a total novice but I have encountered these issues and for what it's worth these are the machine specs and solutions that I have used...
Hardware: Mac Mini PPC G4 (PowerPC 7447A @ 1250.00MHz) Radeon 9200 When running: Lubuntu 14.04.1 With: video=radeonfb: 1024x768-32@60 Result: running fine (no freeze) but with sluggish GUI i.e. slow window drag When running: Lubuntu 14.10 With: video=radeonfb: 1024x768-32@60 Result: sluggish window drag and now freezing issue with only mouse cursor movement With: video=ofonly radeon.agpmode=-1 Result: sluggish window drag but no more freezing issue I haven't tried anything xorg.conf related as I consider this system currently in a usable state. I did go through the motions of the xorg.conf stuff under 14.04.1 but didn't changed anything as I have no idea what I would change. As I said, total novice. I would be happy to try something and report the results if someone would give me some direction. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1377878 Title: PPC - GUI freezes except for mouse pointer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1377878/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
