I tested the ubuntu MATE 15.04 beta2 PowerPC live DVD in a virtual QEMU/KVM machine. Xorg starts but unfortunately some colors are wrong on the ubuntu MATE desktop. I can't use the mate-panel. If I click on the panel (menu, icons etc) then nothing happens. The mate panel and the mate taskbar starts again and again. The beta 1 live DVD works without these problems in a virtual QEMU/KVM machine. On my AMIGA one X1000 PowerPC the beta 2 works very well with the old Xorg packages and Upstart. The temporary solution for QEMU and Power Macs is, to try to install ubuntu MATE 15.04 with the Ubuntu Server ISO or with the netboot CD. The installer runs only in text mode. If you installed it, then you could install the ubuntu MATE packages and the OpenSSH server. After that you could downgrade Xorg via SSH.

Synaptic told us that it want to remove xserver-xorg-video-radeon and xserver- xorg-video-ati. But there are new versions available (xserver-xorg- video-radeon 1:7.5.0-1ubuntu2 and xserver-xorg-video-ati 1:7.5.0-1ubuntu2). Synaptic removed both old packages and Xorg didn't work after that. I selected both new packages and updated them manually. After a restart I had a black screen with a blink cursor. There aren't any error messages in the log file '/var/log/Xorg.0.log' but I found some error messages in the log file '/var/log/syslog': . Exiting.
