I have a system I would be happy for you to play on. At the moment I have only a sacrificial user account and a ssh key set but give me a couple of days to get TurboVNC built and tested (I use X2Go) and I can send you the connection information and public key. This is the A10-7860 system currently running kernel 4.20 amdgpu driver and Mesa 19.0 rc something. I have built VGL from git on this box and I don't think it will be too hard to do the same for TurboVNC. The OS is Mageia 7 Cauldron which is currently a beta release and will be updated daily. This shouldn't be a problem but it may get several kernel and mesa updates over the next week or so... oh, and I am on GMT+0 -- Richard <[email protected]> -- You received this message because you are subscribed to the Google Groups "VirtualGL User Discussion/Support" group.
