WKS Pro 12.5.2 for Linux on Rosa Fresh R8 2014.1 (a Mandriva derivative distribution) on x86_64: kernel 4.9.12, libdrm 2.4.75, mesa 17.0.1 and xorg 1.19.2.
Since a few days ago, when I updated my mesa from 13.0.4 to the latest 17.0.1, WKS does not start a VM any more:
it pops up a little floating window saying "Unable to change virtual machine power state: Internal error".
By looking at the log file and comparing it with an older log from a successful VM start (both attached), I noticed that the bad log file stopped before starting the Shim3D ("Started Shim3D" line in the good log file),
so I tried to set mks.gl.allowBlacklistedDrivers to "FALSE" in the .vmx file: indeed this setting made WKS working, albeit without video acceleration.
The weird thing is that I had run WKS with mks.gl.allowBlacklistedDrivers to "TRUE" since forever (because I have a Radeon video board and use it with the free mesa drivers), and never had a problem at all.
So some change between mesa 13.0.4 (the one I had installed before updating to the latest release) and mesa 17.0.1 broke WKS...
How can I find what is going wrong?
