[Bug 1434036]

  Thread Previous • Date Previous • • Thread Next 
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.

[QUOTE=Martin Wimpress ubuntu MATE google+]
I've pinged some devs. Can you see if 'startx' works and update both the Xorg and LP bugs with the results please?
[/QUOTE]

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'.

[/CODE]

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.

Rgds,

Christian

Bug description:
  Hi All,

  We updated ubuntu MATE 15.04 and Lubuntu 15.04 on our PowerPC
  computers (Power Mac G5 Quad and AMIGA one X1000) last week. 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':

  ------------------------------------------------------------------------------

  I installed Upstart again but unfortunately it didn't solve the
  problem with the black screen and the blink cursor.

  The temporary solution is to downgrade Xorg:

  sudo dpkg -i xserver-xorg-core_1.16.0-1ubuntu1.3_powerpc.deb
  sudo dpkg -i xserver-xorg-video-radeon_7.4.0-2ubuntu2_powerpc.deb
  sudo dpkg -i xserver-xorg-video-ati_7.4.0-2ubuntu2_powerpc.deb

  I created a package with all debs and Mesa libs for the downgrade last
  week.

  PLEASE help us.

  Thanks in advance.

  Cheers,

  Christian
