I've got a Gigabyte Brix GB-BXi7H-5500. This computer only has HDMI and
mini DisplayPort outputs, no VGA.  All the Desktop systems I have tried
to install (Ubuntu, Fedora, etc) have all failed because the screen is
totally unreadable, with graphics flashing all over the place and
nothing sensible to be seen. I managed to install Ubuntu 14.10 server
and installed xinit and twm (yes, those ooollllllddd ways of doing X!).
A barely usable system as long as only xterm was used. Trying to run
e.g. firefox was a total mess (photo attached). So it's not a window
manager issue, nor a GUI toolkit issue: this was absolutely minimal X.
Updating linux kernel to 4.0.2 didn't help. Ubuntu 15.04 was no good -
triple mouse pointers against a magenta screen.

Fix #32 worked and I can play 1080p movies such as Big Buck Bunny (a bit
jerky as no i965 loaded). But it only works once I have the server
install done - doesn't help Desktop installs.

I've also logged this as bug 90401 on bugs.freedesktop.org as "HDMI i915
driver broken on Gigabyte Brix GB-BXi7H-5500"

Bug description:
  Trying to achieve: Get a more stable graphics environment up and
  running

  Steps to take:  basic ubtuntu 14.04 install.  Boot up and run for a
  few minutes and then ...

  What happens: After running for a few minutes the graphics gets
  flacky.

  What should happen:  Graphics should not get flaky.

  I have just installed ubuntu 14.04 on my new thinkpad t450s.
  Everything basically works, but something is very flaky about my
  keyboard or display or both.  After running for awhile some apps
  (E.g., thunderbird and sometimes emacs for example) will display
  garbage.  If I refresh by moving the screen around or changing
  buffers/tabs/etc. they can often recover.

  I see that there is an [Intel(R) Graphics Installer for Linux*
  1.0.7](https://01.org/linuxgraphics/downloads/2014/intelr-graphics-
  installer-linux-1.0.7). I am leery about just loading this and running
  it.  Any suggestions about how I should proceed?
