не в этом дело, "холодный пуск" - идет все прекрасно..., все просто летает, а спустя какое-то время, тот-же Konqueror, в режиме файлового мененджера устанешь жждать, пока он соизволит свои окошечки прорисовать...., тоже с k3b, krusader, amarok и т.д., причем впечатление складывается что тормозят только приложения для Qt, gtk-шные стартуют с "пол-оборота".
PS: вот мой .xsession-errors может он чтонибудь прояснит

$ cat ~/.xsession-errors
