Well, the Ubuntu 22.04 VM froze at some point during the last 24 hours even after having upgrade the kernel to 6.3.7, so there is something else going on here. Yesterday I learned about
Xebian, which is another Debian based distro that defaults to v6.4 of the kernel. I built a VM based on Xebian late yesterday afternoon and it has been up for about 20 hours. I just installed xrdp on it, so we will see whether it keeps running.
