The problem showed up on 8-stable built on March 3 and is still present after an update to stable of March 17. When in vty text mode, after the idle normal delay, the display blanks, but the backlight remains on, so the P in DPMS seems to be less than effective. At that point, the non-graphics display is dead. It never comes back when characters are entered. I can't get the display to come back without a reboot. I can, however, start X (and Gnome) and everything is fine. But switching back to any vty results in a blank screen. Any idea what happened and if there is a fix or workaround? Any data I can collect?
