Screen shot of firefox on Gigabyte Brix with i915 driver
This ultra-compact only has HDMI and mini DisplayPort. On both, with several versions of Linux, X windows shows garbage - recognisable bits surrounded by random graphics. Desktop Linux's won't install as the graphics output during the install process is unreadable.
Managed to install Ubuntu 14.10 server using command-line install. X just about works with xterm and twm but anything like firefox just blows the screen. Screenshot attached. Gnome just as unusable.
Driver is i915. I've run the Intel Graphics Installer 1.0.8 for Ubuntu 14.10 64-bit from 01.org, but it makes no difference. frame buffer is inteldrmfb.
Any clues what I should do?
Please provide 'lspci -vmmnn -s 00:02' for a start.

Fix #36 works from "Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500" at https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1432194. This sets acceleration mode to "uxa". It doesn't help Desktop installs as they still can't be done. Only helps when adding X to server installs.
"try to create the following folder:
sudo mkdir /etc/X11/xorg.conf.d/
Then create inside the new folder a file named for example "20-intel.conf" with the following content:
Option "AccelMethod" "uxa"
Then reboot and voila."

So he is saying that this is a new bug, not the one he fixed. Should I registering it here or on bugs.launchpad.net?

Please test the Xorg ddx driver from  and report back.
Downloaded, built and installed 2.99.917 commit baec802b21... Great! Can play Youtube videos, Big Buck Bunny and glmark2 (only scored 119, though). Looks like this is the fix. Both HDMI and mini DisplayPort outputs are working fine so far. Great job to all the developers. I'll put all my travails with this PC on my blog at http://jan/newmarch.name.
Must be thanks for the nice post here follow here http://controlpanelwindows10.com and seen the function to add control panel icon on desktop in windows 10.
