So I downloaded some kernels from http://kernel.ubuntu.com/~kernel- ppa/mainline/?C=N;O=D

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. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM] PCIID: 1002:6779 I've tested Ubuntu Xenial (16.04) with the latest updates: mesa 11.2.0-1ubuntu2.2 xserver-xorg-video-radeon 1:7.7.0-1 linux-image-4.4.0-47-generic 4.4.0-47.68 xserver-xorg-core 2:1.18.3-1ubuntu2.3 I've tried older kernels, xorg, linux-firmware, as a colleague claimed it started for him after some of the latest Ubuntu updates, but couldn't find a working configuration. 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. Current versions: mesa 12.0.3-1ubuntu2 xserver-xorg-video-radeon 1:7.7.1-1 linux-image-4.8.0-27-generic 4.8.0-27.29 xserver-xorg-core 2:1.18.4-1ubuntu6.1 I'm also going to test Trusty (14.04) to check if it's really a regression. At least I have never seen this problem while running it.
