I ran Ubuntu 13.10 with a startup script that had three xrandr commands in it to add a screen resolution that Ubuntu couldn't detect. After upgrading to Ubuntu 14.04, the system freezes on startup. All I can do is enter terminal mode and type commands.

I think the problem is in the startup script. How do I disable my startup script from the command line?

I tried deleting the original shell file but apparently Ubuntu copied the file elsewhere when I defined it as one of my startup scripts, and the system still freezes on startup.

    Where was your original file? Ubuntu does not, in general, copy scripts automatically. Look for a unique phrase in the file (eg. xrandr --output ...), mount /, then grep -rH 'myuniquephrase . to search the whole filesystem for any files containing that phrase. – bain May 08 '14 at 18:14

    It would be useful if you tell us how you installed the startup script. It is a system startup script, a DM startup script, one of your desktop startup scripts... it is not clear at all. – Rmano May 08 '14 at 18:16
  • Sorry if I'm not clear but I'm a total n00b. I placed the script in my Ricky/Programs directory and then used a configuration utility to have it run on startup. I can't use the utility to remove it because the system freezes long before I can bring it up. I guess it would be a desktop script. – Ricky Bennett May 08 '14 at 18:34
  • If you create a new user with adduser can you log in (graphical) as that user? You could also try How do I reset my Unity configuration?. – bain May 08 '14 at 22:40
  • How exactly you made it run at boot? Where is the script? What's the content? – Braiam May 14 '14 at 13:21
  • The best way to add additional information to your question is by editing it, with the edit button. It is better visible that way, and comments are mainly for secondary, temporary purposes. Comments are removed under a variety of circumstances. Anything important to your question should be in the question itself. – guntbert May 14 '14 at 18:55
