I have been enjoying a smooth Ubuntu experience until recently.
Just sometimes after using Firefox, it tends to freeze up Firefox, System Monitor and other related apps (even the screenshot took). Yet alt+tab works, the seconds on clock on the activities bar is still moving.
I refreshed my Firefox but it doesn't seem to be working. I mostly only installed updates as recommended by the Software Centre and Synaptic Package Manager only.
The only configuration change I did was the installation of the CPUfreq-gui and adjusting the CPU governor (to ondemand to performance and back) and adjusting the maximum clock to 4200Mhz. Also, I added 2 Gnome extensions to monitor the 1) CPU activity and 2) change the CPU governor as required.
I am using a Ryzen 3600 with a GTX 1660 Super with 32GB RAM.
Any ideas where I can start troubleshooting to resolve this issue?
Thanks guys.
EDIT: I managed to track down the issue and it seems that it was the Gnome Shell. It crashed again on me awhile ago too.
I have attached the syslog:
