Public bug reported:
Binary package hint: xorg
If I issue "xset dpms force off" in a terminal (xfce session), the screen goes
blank and the backlight turns off, just as intended. Sometimes though (ca.1 out
of 10), the screen doesn't wake up again. The system seems to be locked up
completely, because the following doesn't work:
* Ctrl+Alt+Backspace
* Ctrl+Alt+Fx
* Alt+Sysrq+(rseiub)
Only turning off by holding the power button works.
AFAIR this problem didn't occur with older releases (jaunty and below).
