[SOLVED] Very slow application launch in KDE

snack · 2011-03-22 16:33:01

Hi, some days ago a nasty makefile tried to delete my / directory while I was trying to compile a program. While it didin't touch anything in my system folders, it made a big mess on my home. I recovered almost everything, but since then KDE is behaving strangely. In particular, launching an application with lancelot or with the standard KDE launcher has become painfully slow. All the KDE applications are affected, but the issue is particularly annoying with firefox. Launching it from the command line, however, resolves everything. Chromium is launched quickly in any case.
I deleted .mozilla and .kde4, but the problem is still there. I have no idea to what look at to try to understand what's going on, so I would appreciate some help...
Thanks.

If you're sure the problem is in your home directory.
The easiest way without any troubleshooting is: (However, you'll have to reconfigure your hold settings, it's annoying).
- Create a folder in /home and move all your important data there.
- Remove your home foler, then copy the /etc/skel/ folder to /home and rename it to your original home folder. (do it in single user mode if you run into trouble: telinit 1).
- Move back all datas.
- Configure all your settings as it should be.
- Reboot.
Not the best solution but the easiest one.

I tried to create a new user and the problem gets solved, so I think that it is definitely something messed up in my home folder. Moreover, the problem must be related to the application launch using lancelot or the standard launcher, which for firefox requires 8 second instead of 2 seconds using the command line.
I'd like to fix it instead of building my home again from scratch, since I'd like to understand what happened and also because I have lots of stuff in it and it would take a long time to rebuild everything.

Oh, you don't have to rebuild everything. Backup your configuration also, then put it back one by one and see what has gone wrong. (All those hidden files started with a dot ".").
I did mean those files are also important data, who would want to lose all the configuration that took so long to do
Shouldn't take too long to figure it out. If it's my configuration, I think I can find out what wrong in less than 15 minutes.
Good luck if you choose to do so.

I tried again to delete my .kde4, and this time I also deleted everything in /tmp and /var/tmp. Now everything seems to work, Firefox launches quickly (BTW, Chromium is way faster at launching than FF! Amazing!). Don't know exactly what did the job, but I mark the thread as solved anyway.
Thanks lives2evil for your support!
