I was given a tip about KDE, and would like to know what other people think of it. Since I upgraded to KDE 4.8.2, sometimes it has seemed like my system either slowed down or locked up. Someone told me to go into the ~.kde4/ directory and then go into the following 3 subdirectories: ~.kde4/cache-<hostname> ~.kde4/socket-<hostname> ~.kde4//tmp-<hostname>
Each of those is actually a link to a directory in the /tmp/ directory.
The idea is to log out of KDE, and then at a console go into each of the sub-directories as root and clear out all the files. There are also sub-directories in each of those, but I didn't clear those as I didn't want to erase all my KDE settings.
After clearing the files out of my directories, it did seem to help my system, but it may just be my perception. It is hard to know for sure. Anyone else out there ever do this and have any ideas on how to do it better?
Yes, but it won't help performance. Whoever told you that is practising voodoo engineering. The opposite is more likely since when you delete the KDE cache you are wiping out the binary cache of all the installed .desktop files (used for the app launcher menu, finding apps, and plugins), the rendered bitmap cache of the SVG theming for Plasma, and the binary cache of the icon theme in use, and any app specific caches - all of which will be recreated during the next login. They don't contain any settings though - even any .ini files left there are temporary. All the settings are under .kde4/share/config, and all the app- local data is in .kde4/share/apps.
My question is, in my .kde4 directory, there are also 3 similar subdirectories that have the names like this: ~.kde4/cache-112 ~.kde4/socket-112 ~.kde4//tmp-112
On my laptop there is even a 3rd set, but my desktop has only these 2 sets.
What are these other sets, why does it have the suffix 112 instead of the hostname, and is it a good idea to clear the files out of those directories as well?
The part after the - is always the hostname. linux-1234 or similar is the randomised default hostname under SUSE, and if you later change the hostname these tmp dirs are left behind. It can't hurt to clean these out for tidyness but won't affect performance. If you are experiencing slowdowns, lockups, and unresponsive KDE, it could be a bug in a kded module which I am currently troubleshooting. The symptoms are intermittently unresponsive global shortcuts such as ctrl-alt-del, unresponsive Plasma, slow to open KDE file dialog integration in Chromium, Thunderbird etc. Can you provide more details on your problem before we move on to slaughtering black fowl over your keyboard and chanting?
