ubuntu - Capture currently running programs as start-up programs - i remember in previous versions of ubuntu there used feature capture running programs, , automatically set them start-up programs. in 12.04 can't find feature anymore. still available? there way manually add together start-up programs, utilize automatic feature used available in other versions. if you're using verion 11.04 or previous can going scheme menu -> preferences -> startup applications -> options tab, , here can check "remember running applications". but if you're using newer version (11.10 or newer) alternative not exist anymore, , no plans implement in near future due numerous side effects. so because you're using 12.04 think that's not possible. i'm not sure kde. also if still want manually add together application startup check here - ubuntu 12.10 ubuntu ubuntu-12.04
