i booted into the nox,then ran startx to gui environmen,it work well,when i shutdowned from gui,it gent into nox command line console,so i had to type poweroff to shutdown.
i made some aliases in .bashrc,but in nox console,i typed my alias,it couldn't be identified,like the system didn't read the .bashrc file when i went into nox console.
in gui,i opened terminal ,ran su spot ,then ran env ,i got env from root not spot,so ,i had to modify some envs' contents,found string "root",replaced into "home/spot",then exported them by writing a script in which export commands were included before a app command,then ran the script from terminal under spot ,or i couldn't run many apps under spot.By the way .no .bashrc file existed in spot home directory
