E233: cannot open display

# gvim /usr/share/X11/xorg.conf.d/10-backlight.conf
E233: cannot open display
Press ENTER or type command to continue

vi will be open instead of gvim.

lxterminal, Beowulf.

It has appeared after ASCII --> Beowulf upgrade.

Anyone know please how to fix it ?

Re: E233: cannot open display

It's always best to enter the error message into a search engine:

https://www.linuxquestions.org/question … ll-751248/

EDIT: better approach:

SUDO_EDITOR=gvim sudoedit /usr/share/X11/xorg.conf.d/10-backlight.conf

^ Run that as your normal user (after installing the sudo package and enabling sudo for your user).

EDIT2: add this to ~/.xsessionrc (or /etc/environment) to set $SUDO_EDITOR permanently:

export SUDO_EDITOR=gvim

Then just use sudoedit to edit system files as your normal user.

Obviously, because you didn't say you did.  A proper answer requires a question containing all relevant information.  IOW, you get what you ask for.

Re: E233: cannot open display

I've read 10 previous threads here (in "Desktop and Multimedia"). There is no mention about using search engine before posting a question and no complaint about it from other users.

So why such criticism in this thread ?

It was intended as genuine advice rather than a criticism.

Hello:

Hmm ...
There is no mention of it because it is basic common sense to do so before posting a question here and in every other forum on the net.
The same way it is basic common sense to then do a search on the site/forum to see if anyone else has come across that problem before you did.
And maybe found (or not) a solution which may have worked for them but not for you.

............................................................................................................................................................................................
Whatever data you find before posting and then share with the forum when you post constitutes relevant information.

No need to take it as a criticism, HoaS always gives genuinely good advice.

I've read 10 previous threads here (in "Desktop and Multimedia"). I was the only one (out of these 10 threads) who was told about making search before posting question. Do you have please explanation for it ?

Re: E233: cannot open display

Yeah, I've read many threads here and still haven't worked out any regular formula for when "advice to search" is administered.

There obviosuly should be a constent rule for it as otherwise any poster might feel left out or fingered; especially those that do search first and don't get any credit for that, as well as those who don't search first and thus suffer an amount of face loss.

Re: E233: cannot open display

It all comes down to chemistry/attitude and action/reaction. These elements cannot be quantified but are an organic part of human interaction. As I said a few posts up, you get what you ask for (even though you didn't think you asked for it).  Perhaps there might be a lesson there if it can be heard . . .

Re: E233: cannot open display

I tried to use gvim as root to open /usr/share/X11/xorg.conf.d/10-backlight.conf i got the same error message. My guess is it is a limitation for running a gui application as root user, a safeguard built into gvim.

I could use gvim as sudo for the same command though.

Re: E233: cannot open display

@boycottsystemd: Assuming you're trying to use gvim while using X.org or equivalent, and are not running from a virtual console, you may have been bitten by the change in 'su -u' in beowulf. It no longer transfers your DISPLAY and XAUTHORITY environment variables to root.

You might try something like this alias:

alias tosu='su - -w DISPLAY,XAUTHORITY'

Then try gvim and see what happens.

Thank you, it works so problem is solved. (X.org, LXTerminal)

Re: E233: cannot open display

Please «boycottsystemd», be reasonable; I don't think there were any ill will in this case.
Good that you found a solution to you're problem, though.
