I tested ubuntu MATE 15.04 in a virtual Power Macintosh G3 Beige QEMU/KVM machine today. I found out that the problem with the mate-settings-daemon is also present in a virtual QEMU machine. I have to login again after the desktop is loaded to get a working mate-settings-daemon.

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. The installer runs only in text mode.

Download: vivid-server-powerpc.iso

If you installed it, then you could install the ubuntu MATE packages and the OpenSSH server. After that you could downgrade Xorg via SSH. What do you think?

Yes, the downgrade fixes the signal 11 errors. I figured out that I have a lot of signal 11 error messages with systemd. With Upstart I have only 4 signal 11 errors:

With systemd, X11 starts again and again with a white screen. With Upstart I have a black screen with a blink cursor.

I added some log files to the LP bug report today.

There's no sign of a crash in the attached Xorg.0.log files. Are you sure it's
Xorg that's crashing, not e.g. lightdm?

Actually, it says right here that the crashing process is lightdm-gtk-gre, not
Xorg. Please file a bug against lightdm.

I installed the display manager "slim". It started and I could login. But I have the same errors with the MATE desktop like on QEMU. 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. And there is a blank error message in the middle of the desktop. I installed lightdm again and I downgraded the Xorg packages again. Everything works without any problems again.

This bug is definitely a Xorg bug. It affects all PowerPC machines. Please look in the following thread: http://ubuntuforums.org/showthread.php? ... st13260389.

Hi All,

I updated ubuntu MATE 15.04 on my AMIGA one X1000 today. And this is unbelievable. Xorg starts with Upstart and systemd. I don't need to downgrade Xorg. But unfortunately some colors are wrong on the ubuntu MATE desktop. I mean I have the same color problems as on QEMU PowerPC. The mate-settings-daemon starts with systemd 10 minutes after the login. With Upstart the mate-settings-daemon works without any problems immediately.

I stopped lightdm with 'service lightdm stop'. After that I started X11 with 'startx'. But it didn't start with 'startx'. I didn't find any error messages in the file 'Xorg.0.log'. I found some error messages in the file '/var/log/syslog'.

I installed Upstart with 'apt-get install upstart-sysv' again and then I downgraded Xorg to version 1.16.0. After a reboot all things work without any problems.
