Re: checkX
$ checkX --version
run2 0.4.2
checkX doesn't work as I understand the description below:
"DESCRIPTION
Determines if X is installed, Xserver is running on specified DISPLAY
and will accept clients. Returns 0 if yes, nonzero otherwise"
Environment / Procedure to duplicate the error:
- I have an X11 server running, started in pty0, where I will test checkX
- In this pty0, I start an X11 server, which from the xinitrc starts up another mintty
terminal, pty1 with Display environment variable set to :0
- Testing checkX in pty1 (which has DISPLAY set) returns a 0 or successful result.
checkX :0 --> returns 0
- Moving back to pty0 and running the same command with the same argument gives:
checkX :0 --> return 1 and error condition or no server available.
However, if I simply manually set DISPLAY=:0 in pty0 X11 clients will run.
- export DISPLAY=127.0.0.1:0
- checkX :0 --> Nnw reports an o.k. this server is useable.
If one relied on checkX the runing server would be missed. It is doing nothing that a check if DISPLAY var is set or not andn then possible testing it. It should has used the value :0 I sent it and do some X11 stuff I am not aware of.
I intented on interating through files in /tmp/.X11-unix/* looking for an active X11 server, but checkX doesn't seem to fit the bill.
Do I have to just manually set DISPLAY and try to run a program that relies on it, since checkX doesn't work by telling me a server can be use, when it can be.
