I'm using arch Linux, i first installed kde 5 three days ago .
at first plasma crashed every now and then (which is expected), but it was a workable environment, Since the 5.2.0 upgrade plasma stopped crashing and started freezing mouse works, but everything else freezes after a while first plasmashell and then everything else. On the system monitor says "Process status sleeping - Process is waiting for something to happen" |

Can you check whether you have "kded5" running?

kded5 seems to be running , even after plasmashell freezes.
(actually twice , one for my user and ine for sddm) Kded4 is also running. Is there a way to get the logs at that time? |

Did you do anything particular before the freeze? Any process hogging the CPU? Best would be to switch to a VT (ctrl-alt-f1 or the like) and check the output of programs like top or similar.

The freeze happens in about a minute after logging in.
No programs running and ksysguarg shows low cpu and memory load I tried removing completely everything kde-like and reinstalling plasma 5 but the freeze still happens This is a 15 minute journalctl log containg a restart, boot, log in nand eventual freeze

Can you still access the dbus interfaces of the "frozen" processes?
Does suspending the compositor (SHIFT+Alt+F12) "unfreeze" things? |

Yeah, no
I assume this took a considerable time until the message appeared (several seconds, like 25?) The process deadlocked somewhere and does not longer process events. -> You can gdb into it when it hangs and check, "where" (you'll likely have to log in from VT1, if - as you said - everything (?!) freezes When the desktop is frozen, do:

it takes a while for everything to freeze.
plasma widgets and panel freeze after 60 sec or so. weird thing is that even with plasmashell frozen everything else works (effects, windows, Konsole etc..)

see https://bugs.kde.org/show_bug.cgi?id=341963
are you pehaps out of space (/tmp, /var, or /home)? - or maybe lack write permissions? |

I think its resolved clearing ~/.cache/ did the trick. thanks . . . . . A LOT |

I had the same issue and clearing .cache indeed fixes the issue. Question is: why? What is cached that could have caused this issue?
|

One can only say that the cache has been corrupted "somehow" - this can be
- a bug in a client writing to the cache - due to "out of space" (ie. /var is full) - some client (*cough* bleachbit *couch*) DELIBERATELY damaging the cache. No other info can be provided by static data. If you're not out of space and run "some application" and afterwards things go south, "some application" is likely the culprit. |
