Unplugged second screen, lost kwin

[whatthefunk]

I have an HDMI cable running from my Kubuntu 15.04 box to my TV. I was messing around with the plugs and unplugged the TV while the Kubuntu box was on and plasma crashed. I tried rebooting, but my desktop wont load. Im left with a completely black screen. Ive tried restarting plasma several times, but it fails with no error message. Any ideas?

Im getting a DBus error sometimes when trying to stop/start plasmashell.

$ kquitapp plasmashell
kquitapp(2949): "Quitting application plasmashell failed. Error reported was:

     org.freedesktop.DBus.Error.NoReply : Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

GPU info?

@hear when I do that it just drops the TV ,,,,,,,did you reboot with the TV plugged back in .

did you try booting with the "nomodset" option on your grub boot line?

I dont think this is a GPU or grub issue. I get to the login screen fine. After entering my password, everything goes normal, but then when the progress bar gets full, it stalls, appears to timeout and then I plunge into darkness. I can still run programs if I start them from the command line. Im using Firefox to type this message now.

Got it working. Simply moved .config/plasma to a backup and it regenerated itself.

~$ mkdir -p plasma
~$ mv .config/plasma* plasma/
