I start pc, it goes through bios ok, goes through grub ok, even displays xubuntu splash image (big xubuntu on blue-white background) and stops. I can get in tty1, even log in, but no desktop. Tried startxfce4 only to see fatal server error server already running. How do i get my desktop back, as it was before this problem, without reinstalling my system preferably. Also, im not-native english, linux beginner.
edit: it is dell optiplex gx280, no wifi, no bluetooth, graphics card is eah5450 silent/di/1gd3(lp) with the graphics engine AMD Radeon HD 5450.
Yesterday i turned it off like every day, and today its stuck on black screen.
Not fixed, reinstalled.
