laptop monitor black/purple after boot since update

Postby duped » 05 Mar 2015 18:00


My laptop had an uptime of about 30 days until yesterday when I accidently pulled the battery lock swtich and it fell out so the machine lost power. I had been installing updates in the meantime but upon startup, nothing would display on the laptop screen. It seems that others are having problems with plymouth update this month, I wonder if it is related.

The laptop screen will not display but has a purplish light also it will still run my older solydk display (from about early Jan), i.e the screen is working fine. I have a docking station with monitor and tried it there to discover that they system is on and working and think it is using the display but shows nothing. I need to go into display settings and clone the screens and can only work on my monitor but not laptop screen. However this is still not working correctly because big flashing black box starting from the bottom covers the screen up to the mouse pointer (I am sure this is to due to cloning displays of different resolutions, but I am not too worried about this presently, I just offer it as a potential diagnostic). xrandr and kde display show that the monitor is connected at the proper resolution, however.

If disconnected from the monitor nothing will display on the laptop screen, even upon fresh startup.

other info:

in virtual terminal a message given
"xset unable to open to display "" "

I have tried the "noplymouth", "nomodeset" and "nosplash" options in grub but it makes no difference.

Any help appreciated to get the laptop screen working in particular.
