I'm running Ubuntu 12.04. Earlier today I launched startx and got a blank wallpaper-like screen with nothing on there. I thought maybe it was taking time to load but it would just remain stuck there. Looking for a way to get back to the command prompt, I pressed Ctrl+Alt+F6 and got back to the command prompt. Later today, I tried launching startx again and got this error:
Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.
Please consult the The X.Org Foundation support

for help.

Someone here suggested to type in sudo stop lightdm and someone else over here suggests to type sudo service lightdm stop, however both give me the following message:
stop: Unknown instance:
I tried killall X which gives me:
X: no process found
I'm not so sure about deleting /tmp/.X0-lock because the first link up there says that deleting it just gives you the error message cannot create file /tmp/.X0-lock instead. By the way cat /tmp/.X0-lock gives me:
14275
but that process doesn't seem to show up in top, although it may be way at the bottom, I'm not sure how to scroll down.
What should I try next?
