November 12, 20214 yr Hi all, I'm not sure if this is an unRAID problem, Linux Mint problem or KVM problem, but as the VM runs on unRAID I figured I'd try here first. Last weekend, I upgraded my unRAID server and installed an extra CPU, more RAM, a USB controller, a wifi/bluetooth card and an AMD Radeon HD 8570 GPU, and then migrated my physical HTPC to a VM. The GPU, USB controller and wifi/BT card were passed through to the VM and everything mostly works. The first problem I encountered was that playing videos in VLC yielded no video, only audio. That was fixed by setting the decoding to Xvideo in the VLC settings. The second problem was that the screen saver kicked in after 15 minutes, locking the screen. That was fine, the system worked perfectly after moving the mouse; I was let back into Mint no worries. However, if the system was left for another 15 minutes, Mint turned the screen off. When trying to wake the system back up by moving the mouse, the screen turns back on, but the keyboard was unresponsive. I can move the mouse cursor, but can't click anything. There are also minor graphical glitches in the display output. A CTRL-ALT-Backspace will kill and restart the X server, and then everything works. The downside to this approach is that all open programs are also killed and need to be restarted, which, for a HTPC isn't much (Firefox and VLC, usually). The major downside is that the other members of my family sees this as "Linux is unstable", "The setup isn't working" and thus the onus is on me to fix this post-haste, as "the old HTPC just worked for years" - which is true; the old system was set up with Mint in 2016 and hasn't skipped a beat (except that one time I uninstalled the display manager by accident...). Yesterday, I changed the power settings in Mint to never turn off the screen, and I haven't heard anything from home indicating that the HTPC has locked up. Has anyone seen similar behaviour/problems before and if so, how did you fix them?
