I would run a cron job like this: mar...@shambhala:~> du -sh .thumbnails 434M .thumbnails mar...@shambhala:~> find ~/.thumbnails -atime +30 -type f | wc -l 10030 mar...@shambhala:~> find ~/.thumbnails -atime +30 -type f -delete mar...@shambhala:~> du -sh .thumbnails 30M .thumbnails This way you have the most recently accessed thumbnails at hand while still reducing the size of the directory by a big margin. Note: This will not work with noatime ;-). There you could go after mtime or ctime, but this might delete thumbnails created long before even so they are still being accessed regularily. I use relatime here. Of course, the user should be not be required to create a cronjob for that, but I have a lot of those already, so i do not mind for now. I use the handy fcron for it: mar...@shambhala:~> fcrontab -l 17:04:44 listing martin's fcrontab # Backup der KDE-Konfiguration @ 2d /usr/bin/rdiff-backup ~/.kde/ ~/Backup/KDE @ 2m /usr/bin/rdiff-backup --remove-older-than 2M --force ~/Backup/KDE # Backup der Iceweasel-Konfiguration @ 2m /usr/bin/rdiff-backup --remove-older-than 2M --force ~/Backup/Iceweasel @ 2d /usr/bin/rdiff-backup ~/.mozilla/ ~/Backup/Iceweasel # Spam wegräumen @ 2d /usr/bin/find ~/.crm114/reaver_cache -type f -and -mtime +1 -delete # Thumbnails aufräumen, 17.5.2010 @ 10d find ~/.thumbnails -atime +30 -type f -delete # Statistiken @ 5d /home/martin/bin/machine-update -m @ 5d (w ; cat /sys/power/tuxonice/debug_info) | mail -s "TuxOnIce stats" mar...@localhost @ 1m uprecords | mail -s "Uptime records" mar...@localhost > So yeah, it's a fairly epidemic problem.

Deactivating all debug output in kdebugdialog has helped here a lot: mar...@shambhala:~> ls -lh .xsession-errors -rw------- 1 martin martin 3,9M 17. Mai 16:31 .xsession-errors Just check the checkmark option at the bottom of the window. In case of debugging a problem, you can activate it again. I think debugging should be off by default. -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7
