Bug Description
After updating from saucy to trusty armsoc exynos driver stopped working on Samsung ARM Chromebook. Just after booting the system screen goes black and only mouse coursor is visible. I can move it, but screen is still black. Similar problem was described on blog: http://
"Turns out my device booted fine into Trusty, but it would only show a black screen with the mouse cursor. If you moved the mouse, you could see the cursor changing but still nothing else."
It may not be the same issue as that patch seems to have already been applied...
The workaround is to use fbdev that works properly.
