openGL

[P-I H]

The Wayland login and my openGL renderer "Radeon RX 580 Series" disappeared after today's updates.
There will be no more gaming until this is solved.

The problem is kernel related. When I boot with the "4.13.0-17-generic x86_64" kernel the system works OK.

[Yellow Pasque]

You are still using 4.15 rc3? rc6 is out now. Maybe try upgrading to that first.

[P-I H]

I removed 4.15-rc3 and went back to the 4.13.0-17 kernel, which still is used in Bionic in case you don't have proposed enabled.
I will wait to try a new kernel until the problems with Meltdown and Spectre are solved.
Also there hasn't been a new Daily Build available since 3/12.

You would want to run the 4.14.0-14.17 kernel which is now available, it has the patch for Meltdown and Spectre and openGL is working at least on my Nvidia-box.

[P-I H]

Installed 4.15.0-041500rc7, with the patch for Meltdown and Spectre, that works OK.
Made some performance tests, with about the same results as before.
CIV VI 20.93 turn rater
K10 max temp 55 degrees
CIV VI + Handbrake to encode the file "SES.Astra.UHD.Test.1.2160p.UHDTV.AAC.HEVC.x26 5-LiebeIst.mkv" using the preset "Fast 1080p30"
ETA 2.34 minutes
Average FPS 44.68
K10 max temp 75 degrees

So did that kernel solve the problem with no hardware 3D accel? If so, please mark your thread solved (thread tools menu above first post).
