4.6 DM/i915 test report on Bay Trail (Celeron J1800)

Hi Natasha,

Did you ever try to load a recent linux distribution onto the NUC? I ask that question because I also own a NUC (the pentium one, with the same graphics) and I saw the very same artifacts you’re talking about with Fedora 23 and 24. If you boot the Fedora 24 live media, you are likely to see them too. On Fedora 23, they only appear post install.

I’m mentionning this here because as far as I know, the FreeBSD intel driver is ported from Linux, and I’m afraid that those issues were also ported with it.

On the Linux side, those artifacts made the computer unusable. One way to get rid of them was to disable SNA acceleration in xorg.conf. This change has a cost, though, as it dramatically slows down the graphical rendering. Another one was to switch from Xorg to Wayland, which seems unaffected by the bug, probably because it does not use the same acceleration preset.

Interestingly, I never saw those artifacts with OpenSUSE Leap 42.1. It seems they were not widely discussed: I did not find any reference to them on Google.

I hope this helps a little,

Marin.
