The "black screen" problem is still alive! (Core i3 530 with integrated
graphics)
Reliable workaround:
1. For every user on the machine repeat step 2, 3 and 4
2. go to "System", "Settings", "Keyboard Shortcuts"
3. add a shortcut
name: e.g. "Fix black screen"
command: "xgamma -gamma 1.0"
4. assign a combination: e.g. "Crtl+Esc"
Whenever you expirience the problem, do the following:
- type in the password of the user you want to switch to
- apply the keyboard shortcut (in my case "Crtl+Esc")
That already saved me at least a hunderd times.
Good luck!
