By default (at least on my machine), it wasn’t possible to open X applications using sudo. For example sudoing xclock resulted in the following error:
$ sudo xclock No protocol specified Error: Can't open display: :0.0 |
The same error appeared even when I executed xclock after running sudo su.
Apperantly, by default the X server doesn’t allow anyone else besides you to open windows on the display. While it’s generally a good thing, it’s annoying if you’re trying to preform some GUI stuff as root. You can use the xauth utility to grant permissions to other users. For example:
$ xhost local:root non-network local connections being added to access control list |
Allows root user connecting from the local machine (like sudo) to access the X display for your user. You can see the current access list by simply typing xhost.
Hello Guy! I have been following your blog for a while.
Quite liked the source-code posting style. Which plugin do you use for the same?
I found Github-Gist cool too! One can just push to Github without worrying about updating the blog post.
Hi,
I’m using wp-syntax. Github-Gist looks very nice, I didn’t hear about it before. There are two things which trouble me with it:
1. The embedding code is javascript. This means that if I search my blog for some code, it won’t find it in the snippets.
2. What happens if somebody else pushes changes to my gist? Will it update my post too?
