Recently, my Intel Nuc10 based system I have been running for quite some time now has stopped suspending. Well, it suspends, but it never resumes.
Prior to this, I have been able to either explicitly suspend (power button, or menu item) or let it decide to automatically. Zero resume issues. Recently, 100% broken. If it suspends, it will not resume. Suspend/resume was 100% reliable. Now it is totally not.
Since a month or so ago, I find that I can be using Firefox in a fc-36-based VM, and after a while, switching between TABs stops working. IE: I click on the TAB in FireFox and nothing happens. It seems the entire FireFox is frozen, but if I diddle about with other windows, or resize the FireFox window, it “wakes up” again. I thought it was an issue of memory bloat and paging, but I increased the memory to certain AppVMs and have been watching the memory (via top
and also some Firefox internal process listing) and I see no evidence of bloat, plus zero paging to swap. Happens when I have multiple windows open with multiple TABs and also when I have just one window and a few TABs. Not 100% sure, but it is not isolated to one particular VM.
Prior to the recent FireFox freeze (which I sort of think is X server related) I used to frequently have old window partial contents left on the screen. Like the X server did not process all the exposure events properly. Moving some window thru the non-redrawn area would, natch, fix it.
Anyone else seeing anything like this?
My system is fully up-to-date and sufficiently rebooted.
Being paranoid, I wonder: Have I been hacked? Is there a RAT running? Due to both of the above issues, I reboot (full system) and restart (individual AppVMs) frequently, but whatever the issues are, they come back.
