im having trouble with slitaz 2.0 running on a toshiba satellite. slitaz runs great and so do all the programs i've updated it with. but it seems whenever i walk away from the system for a few minutes, when i come back the computer is completely frozen. i cant even ctrl-alt-del or ctrl-alt-bksp out of X. the only thing i can do when this happens is a hard reboot. also it doesn't seem to matter if there are programs running or not.. any suggestions would be great!
