Hi Bjoern,
Since some days I have the problem, that "plasmashell" from plasma5-workspace-5.8.4-1.1 (latest Tumbleweed updates) freezes often (around every 30 minutes).
"top" shows then:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4340 myuser 20 0 8881100 4.116g 158576 R 100.0 26.37 18:57.14 plasmashell
Killing plasmashell und restarting it with "plasmashell --shut-up" resolves the problem until next time.
Anyone else with this problem?
Yes, here. Been happening every once in a while since about summer, I guess. Restart helped. I could not really detect the source, but i have several suspicions: a) It seemed to happen only on systems that had self-updating widgets (cpu load, network load, ...) b) removing plasma config files (incl. the widget stuff and definitions) helped... on some systems. c) Plasmashell didn't freeze, it just used one CPU core fully. Never two or more, always only one - but that also doesn't say anything helpful. Multicore systems remain usable, but slow down. It's especially annoying on laptops, since it drains battery very fast, and that is sad, because KDE is doing very very very well with battery consumption (even with akonadi running I often manage less than 4 Watts on two different laptops - reported by powertop/system and confirmed by runtime)
I observe two incarnations of this problem on my machines. On my notebook plasmashell freezes whenever a notification pops up. I see an empty frame and then everything freezes. This can be worked around by disabling notifications at all. On this machine an Intel graphics adapater is used. The problem happens with the Intel driver and also with the modesetting driver. On my desktop plasmashell also freezes randomly, but I couldn't identify a single reason. This machine has an Nvidia graphics adapter and the problem occurs with the proprietary Nvidia driver and also with the modesetting driver. I supect the problems stemming from Mesa, but I have no proof of this.
Greetings, Björn
Bye. Michael.
