While keeping the Xenial HWE stack on Ubuntu Trusty (14.04), I tried various installed HWE kernels.
It seems it really broke with the Wily kernel (4.2.0.42.34). The Vivid kernel (3.19.0.74.56) has survived multiple resume cycles, while Wily instantly created the problem. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1643843 Title: Distorted colours after suspend / resume cycle Status in xorg package in Ubuntu: New Bug description: When waking up the system from a suspend-resume cycle, the display most times shows distorted colours. As a workaround one can switch to the linux console (VT) and back to fix the display. Alternatively triggering DPMS also fixes the problem (xset dpms force off ; sleep 0.1; xset dpms force on) Hardware: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

I also checked Ubuntu Yakkety (16.10), where I couldn't reproduce with XFCE, but instantly with the Unity session, but probably XFCE was just lucky, as sometimes I also had series of working (~5) cycles.

At least I have never seen this problem while running it.
