I've been running into a very frustrating issue trying to move to 16.04, the graphics output is completely glitched to the point the system is basically unusable.

enter image description here

This starts during the initial boot screen after selecting 16.04 in GRUB, and persists through logging into the desktop.

I have an intel i5-4590 (Haswell) that I use with the integrated HD 4600 graphics. I have been using this setup with 15.10 and 15.04 without an issue.

I initially upgraded via dist-upgrade, but I found the issue is present when booting from the install disc for Ubuntu, Ubuntu Gnome, and Ubuntu MATE as well when I went to do a fresh install. Applying the most recent pathces has not made a difference, neither has turning the Intel microcode drive on or off.

I've tried reinstalling xserver-xorg-video-intel, libgl1-mesa-glx libgl1-mesa-dri, and xserver-xorg-core but no change.

Any guidance or suggestions appreciated!

  • Thanks, that looks promising. Unfortunately I have not been able to switch to uxa successfully. I added a 20-intel.conf file to /usr/share/X11/xorg.conf.d/ the the 'AccelMethod" "uxa" option, but I see that SNA is still in use from the Xorg.0.log file. – C Baker Jul 07 '16 at 01:06
