This is probably bug 1440570 (the Trusty fix is waiting in the queue).

For the rest please open new bugs.

  gnome-session-flashback/Unity fails to start without hardware

Bug description:
  == Impact ==
  It was impossible to launch a gnome-session-based desktop on a system where 
hardware accelerations is not available (such as old hardware, or when using a 
remote desktop).

  That looks like a quite popular use case — more than a hundred of
  people marked this bug as affecting them.

  == Test Case ==
  The original bug description below contains a test case.

  == Proposed Fix ==
  The fix backports an upstream commit which adds --disable-acceleration-check 
commandline option, and makes Upstart user session pass that flag to 
gnome-session when the session is gnome-fallback (aka 
gnome-flashback-metacity). Of course, that option can be used with other 
sessions as well.

  This was fixed in vivid in version 3.14.0-2ubuntu4.

  == Regression Potential ==
  The option was accepted upstream, and nobody complained so far. So the 
regression potential should be low.

  This bug will cause static grey or black screen instead of opening
  remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from
  x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and
  etc.

  == Original Description ==
  1) lsb_release -rd
  Description:  Ubuntu 14.04 LTS
  Release:  14.04

  2) apt-cache policy gnome-session
  gnome-session:
    Installed: 3.9.90-0ubuntu12
    Candidate: 3.9.90-0ubuntu12
    Version table:
   *** 3.9.90-0ubuntu12 0
  500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages
  100 /var/lib/dpkg/status

  3) What is expected to happen is when one installs xrdp on the host
  and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP
  in, it works.

  4) What happens instead is it shows a gray static screen as per attached 
screenshot. This would appear an issue with gnome-session as per client log:

[Desktop-packages] [Bug 1449892] [NEW] yuv to rgb translation is faulty for Intel Generation 8 Graphics

2015-04-29 Thread Uwe Koziolek

Public bug reported:

running mplayer or vlc the video output is incorrect. There are are 2 line
steps on edges.
The problems is known and there is already an upstream fix available.
http://www.spinics.net/lists/intel-gfx/msg65030.html

I have rebuild the driver with git from 2015-04-28, and the video output
is correct now.

The bugfix is for Generation 8 Intel graphics like Intel NUC with Core I5-5250
and HD6000 grahics in my case.
The used version is Ubuntu vivid amd64.
