I have an Ubuntu machine on which I installed KDE and since day 1 the plasmashell process was leaking memory and my panels just became extremely unresponsive over time.
Now I would like to check the logs to see if I can find the cause, but I just don't know where they could be. I checked /var/log for a kde or plasmashell directory and I also checked ~/.kde for any sorts of logs, but I couldn't find any. I also checked dmesg and journalctl. The latter had some lines about KScreen, but that's about it.
Does KDE/plasmashell even log anything? If so where can I find it?
