noob here... searching for a while for the answer to this but haven't had any luck.
I am out of town and just fired up my laptop but got a black screen only. Totally my fault because I usually have a monitor plugged in and (with the help of an few websites) wrote a script to keep my laptop display off, but I forgot to disable it before travelling now I am kinda screwed.
I managed to get a terminal up and tried playing with xrandr but it just keeps telling me 'can't open display' whenever I try something. I don't remember what the content of the script was but xrandr sounds farmiliar.
So I am a little frustrated and could use some help.
I have an acer aspire 5315 running lubuntu (most recent stable, 13.04 I think?) Nothing fancy or crazy...jus need to get it working so I can get some work done.
Any help would be greatly appreciated!
