Forum Debian Users Gang

witam,
jestem nowy na forum. dotychczas radziłem sobie z debianem i miałem potrzeby pisać nowych tematów.
ostatnio na nowo zainstalowałem debiana 9.12 KDE i mam problem z usypianiem systemu do RAM.
na początku sie wyłączał ale nie dawał sie obudzić, teraz po iluś tam różnego rodzaju próbach naprawy wychodzi do ekranu ponownego logowania.
proba instalacji sterowników karty graficznej zakonczyla sie ponowna instalacja linuksa...
