RE: [gentoo-user] Root cannot open display
When I'm logged on as a user, and I try to open gvim or firefox by su'ing or sudo'ing as root, I get the following error. E233: cannot open display By default X.org disables tcp access. To enable root (or another user) to open windows on the display you need to: 1. remove the -nolisten tcp from the config files in /etc/X11 and the startx script (if you start X from the console). 2. use the xhost command to allow users to open windows in your session.

Re: [gentoo-user] Root cannot open display
Hi! If you're not on an outside machine and security is not really a concern for the moment you can try xhost + as the user and then su to root. This disables access control; you might want to be careful. When you are done you can reenable it by xhost - after root logged off. This is a rather quick approach, but if you just need a window every once in a while it's okay.

You could (as root) copy the mit-magic cookie to root's directory (/root). This is usually the recommended way, from a security point of view. X clients scan the home directory for the mit-magic cookie (.Xauthority) and only allow those who can produce said cookie in their home directory to connect to the X server.

If nothing else works: 'cat textfile EOF', copy with your mouse, press ctrl-d, insert contents of textfile to wherever you want.

Hi Bill, normally it should work with sudo.

Please comment out the line Defaults env_reset in your /etc/sudoers (if it isn't) and try again Ulli Your suggestion for /etc/sudoers solved the problem for gvim, but firefox was very unhappy, root needs to own the firefox profile in the users home directory. I think sux might be a possibility, but I need to look at the implications of it. Lastly, if I can figure out the MIT-magic-cookie thing, I might try that as well. Thanks to everyone for pointing the way(s).

In vim at least, I believe :set noai also works as a nice short hand. Another nice command is :set paste which implies noai but also prevents line wraps, which, although not a problem in C, could cause a LOT of pain in shell scripts.
