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"
