avoid boot into xbmc - ubuntu 14.04 alongside win 8.1

If you launch a terminal using CTRL + ALT + T can you give the output of:

uname -a; lsb_release -a; dpkg -l | grep linux-image

Thanks

OUTPUT:

Then you only have one kernel. You will probably find the other option in Grub is recovery mode which is extremely useful.

So, when you log in to Ubuntu, XBMC automatically loads? Is that correct?

<So, when you log in to Ubuntu, XBMC automatically loads? Is that correct?>

Yes, that's correct. This is at this moment my main concern.
Why would "the other option (i.e. the doubled boot option?) in Grub recovery mode" be extremely useful?

Another observation in this context: There is a partition sda9 of 20 GB (!) in my table which I did not conscientiously create and therefore do not have an explication.
This partition is flagged as "hidden" and labeled as "restore". Mount-point: /media/ubuntu/Restore1

Another similiar partition is apparently part of the windows related ones. sda2 (728 mb only) Is also "hidden", labeled as "recovery1", mount-point "/media/ubuntu/Recovery1".

If there is a need and a chance to upload (how-to?) a screenshot of the partition table here I could do that, too.

If you look in the ~/.config/autostart folder do you see anything that is running XBMC?

Usually you have some options to leave xbmc:
a) press S in the main menu (that should bring up the long shutdown menu) → Leave
b) press \ (backslash) or the key combination on you keyboard layout to do a backslash. This should bring xbmc into windowed mode.

If both don't work you might have selected XBMC as the X session. You can change that in two ways:
a) at the logon screen, click the icon in the login box and choose Ubuntu / Unity
b) Press Ctrl+Alt+F1 to get to the console login → login with your credentials → run

  nano .dmrc

  Edit the line with the session to "Session=ubuntu" → press Ctrl+X → Y → Enter
  Back at the prompt hit Ctrl+Alt+Del to reboot.

@ actionparsnip:

please give me the complete command ( /.config/autostart: "command unknown")

@ Thomas Krüger:

\ brings XBMC into window mode - but again there are no more alternatives than favorites (*) or shut down (symbol) All icons in the shut down menu ("inside" XBMC window) affect the whole system (not only XBMC). When XBMC is windowed rest of the screen remains in typical 14.04. colour but no icons for any command

Login via console with credentials running "nano.dmrc": command not found

Its not a command. Not everyting people wrote here is a command.......

run:

~/.config/autostart; ls

What is output?

SOLVED

Thxs to both of you. The solution was as suggested by Thomas Krüger)

".....at the logon screen, click the icon in the login box and choose Ubuntu / Unity"

If one knows that XBMC is installing an own direct path to login......... starting with a choice in the login box. I learnt it only today.
