I have recently been having problems with video in Virtualbox that suddenly developed, in that I didn't make any changes to the system other than required updates. I am curious if it could have anything to do with the video on the host system. I was running VBox 6.1 and everything was fine for a while and then problems started where video wouldn't play and the machine would bog down.
The only thing I can guess right now is some update caused conflicts with the driver being used, which appears to be Radeon. I have re-installed VBox, installed an earlier version, tried different distros and results are all pretty similar. I just installed Manjaro and it is the least affected but tells me I do not have hardware acceleration enabled when I start the machine, even though I do have it ticked in the 'Settings'. (Note: this is my first attempt at Manjaro so it may be that I need to change things in Manjaro - fairly steep learning curve with my first jump into Arch).
Guest additions are installed, it gets worse the longer the virtual machine is on and processes in the host can make things really slow. The only reason suspect the video setup is that the audio is still being processed while the video freezes. Host system is fine and I have tried all sorts of memory, processor and video combinations.
Ubuntu 16.04 with Cinnamon desktop. Here are some outputs from commands suggested from other posts. If someone could suggest where else to look for clues, it would be much appreciated. BTW, I have read some post regarding the use of AMDGPU in 16.04 but I still don't understand which is the best driver to use.
Thanks
