Just reporting back, FYI, on this issue. I am now experiencing these hangs on a native bare-metal Ubuntu install on a separate computer. So it has nothing to do with virtual machines.
At one point when it hung I was clicking around and saw this dialog to show on a side monitor: [image: image.png] (Image looks like hell because I had to take a photo of it with my phone, as the system itself was locked up) That led me to this forum online: https://youtrack.jetbrains.com/issue/IDEA-246854/File-system-synchronization-popup-blocks-UI This suggests the problem to be an IntelliJ IDEA issue. It has been open for YEARS now probably because there is no reliable way to reproduce it. My question: Why isn't anyone else using IntelliJ IDEA having this problem? And why did I start experiencing this last November, and not before then? I can only suspect the issue is about some IntelliJ IDEA update aggravating the problem, possibly in combination with a Ubuntu update. Alas the oldest backup of my VM configuration is from December when I was already having this issue. I have seen this problem now on both Ubuntu 20.04 and 22.04 on VMWare VMs, using MATE and Xubuntu desktops, and now on a bare-metal Ubuntu Mate 22.04 install on a different laptop.
