[Desktop-packages] [Bug 1894666] Re: Gnome high CPU preventing login after screen lock
Daniel, after further extensive testing and trialling. I can confirm that the high CPU problem does not occur when I disable all GNOME extensions. When no gnome-extensions were enabled the problem did not occur. However, I was able to make the high CPU problem appear by running the dock gnome-extension. I have noted a reduction in the frequency of this problem after the recent set of patches. As you are already tracking a similar issue caused by gnome-extensions I am happy for you to close this ticket. However I am also willing to send you any further information if you want more data.

*** This bug is a duplicate of bug 1849142 *** https://bugs.launchpad.net/bugs/1849142 Daniel, I disabeld the extensions and confirmed that the directory mentioned above is not present. I am still experiencing the following. After being away from my machine, I come back to find the screen locked as expected. The privacy settins are Blank screen display = 10 minutes & Automatic Screen Lock delay = 30 seconds. When I move the mouse or hit a key to login, the machine is unresponive. After about 2-3 mins the login prompt will appear but still remains unresponsive. I usually SSH to the machine using my ipad. With HTOP I find gnome-shell at 99% CPU or greater. If I kill the high CPU gnome-shell task I can login straight away. Sometimes after killing the gnome-shell it starts up again and goes stright to high CPU. If I kill it 4 or 5 times it usually then restarts with low/normal CPU usage.

*** This bug is a duplicate of bug 1849142 *** https://bugs.launchpad.net/bugs/1849142 Daniel - I had the issue happen a couple of times tonight. While the UI was unresponsive, I was able to use another machine to SSH to the PC and run the journalctl command you recommended. The attached file journal6.txt contains 2 incidents one at around 17:49 and the other around 19:58 In both cases, I used HTOP to find the gnome-shell task running at 100% cpu then kill it. That fixes the problem and lets me log in again. Please note that these logs were recorded with the AppIndicators extension turned back on. After still experiencing the problem with AppIndicators I turned it back on. Let me know if you're prefer the journal file without AppIndicators on. Appreciate your efforts in assisting to track down this issue.
