One issue that was bugging me for a while was the different font size (after adjusting it) on couple applications (including Adept) under my fresh installation of Kubuntu Interpid. After investigating and Google-ing I found out that it was due to running those proccesses as “root” which had different fonts and GTK+ settings.
$ kdesudo systemsettings
After running the command above setup the font size as you like it. Working as normal user is something new to me and I’m not sure I like. Needing to write my pass to many times and having to chown my old files is just not that pleasant.
