Hi all, 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? 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?

If you are not logged in, you can safely erase everything in /tmp. You can use runlevel 1 to make sure. - -- Cheers / Saludos, Carlos E. R.

Hi George, I run GNOME so I can't answer all of your questions, but there are some settings I always make in YaST2's /etc/sysconfig editor 'System' -> 'Cron' TMP_DIRS_TO_CLEAR /tmp /var/tmp CLEAR_TMP_DIRS_AT_BOOTUP yes There are some related 'fine tuning' settings in the same area but I don't use them. These specific two help to keep /tmp and /var/tmp from inadvertently filling up my '/' partition in the background and triggering other problems. hth & regards, Carl -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

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

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?

I have an asus laptop exhibiting extreme slow-down with Tumbleweed and kde4-4.8.2. May be related. It is primarily a test box, what information would you like.

If the mouse pointer locks up during the slowdown, it's not my issue. During the slowdown, does 'qdbus org.kde.kded' hang or return a list of services? (the content is not important, just whether kded4 answers). If it responds, it's also another issue. It's been seen on 12.1 so stay on this list for now until I can determine which kded module actually causes the bug.

After updating my laptop (12.1, KDE 4.8.2) the desktop became extremely slow and found that if I turn off desktop effects all came back to life.

It does, indeed. Works fine on my desktop, just the laptop has difficulties. Probably should have noticed when openbox-kde ran normally pushes one to suspect database activity which I did not have or prettiness. tks, -- (paka)Patrick Shanahan Plainfield, Indiana, USA HOG # US1244711 http://wahoo.no-ip.org Photo Album: http://wahoo.no-ip.org/gallery2 http://en.opensuse.org openSUSE Community Member Registered Linux User #207535 @ http://linuxcounter.net -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

no, it appears nearly normal, perhaps a bit slow

disabled "Desktop Effects" and normalicy returned, so did not try but will if you want.
