"export DISPLAY=:0 ; xterm" gives "xterm: Xt error: Can't open display: :0" error.

Open abinashdash17 opened this issue 7 years ago • 12 comments

I'm using debian on a termux chroot environment. When my mobile data is on(i doubt same will be the result on usb tethering and Wlan too), I tried running export DISPLAY=10.94.XXX.XXX:1 ; xterm and to my surprise it's running fine. But setting DISPLAY=:0 gives can't open display: :0 error(with or without mobile data). Is there something I'm missing? Is there something more needed to be configured? I had same issue, when I was trying to run xterm from GNUROOT Debian. So I think, it's not a termux issue.

How did you install xterm? I just gave it a try, and export DISPLAY=:0; xterm works fine for me with termux and xsdl.

Termux --> installed debian chroot from this --> apt instal xterm -->exit and login using termux user(non-root) to debian --> export DISPLAY=:0 ; xterm --> xterm: Xt error: Can't open display: :0
How can I debug the error?

env DISPLAY=10.94.XXX.XXX:1 xterm works fine though.

Maybe try running xterm with strace for a clue as to what's going wrong.

I'm able to use xterm from https://github.com/xeffyr/termux-x-repository as well as xterm from within an Arch Arm Linux chroot (via termux's proot).

I tried installing xterm from xeffy repo. Got some libxinema.so error. Then I downloaded that package. After that If $DISPLAY is 10.94.xxx.xxx:1 it works fine, but same error if $DISPLAY is :0
I'll try strace.

Plz help me debugging the problem.

ADA@termux:~$export DISPLAY=:0

I've no clue, how to debug this.

abinashdash17 avatar Mar 22 '18 06:03 abinashdash17

Comparing your strace to mine, the difference is your connection attempt here fails where mine succeeds:

connect(3, {sa_family=AF_INET, sin_port=htons(6000), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ECONNREFUSED (Connection refused)

Just guessing here, but maybe there's some kind of firewall blocking the connection attempt. What version of Android is on your device? My phone is running 7.0.

robsmith11 avatar Mar 22 '18 12:03 robsmith11

Mine is 5.1. In a different phone(android 5.1), there's no issue. It might be an issue on samsung devices(mine is J2).That might be the reason. I've rooted my phone recently. I can change something to unblock the firewall if you can give some hint.

abinashdash17 avatar Mar 22 '18 13:03 abinashdash17

Unfortunately I know very little about Android internals, so someone else will need to help you there.

Another thing to look at is SELinux. I don't know much about it other than it can be very frustrating. I ended up fighting it quite often when trying to do seemingly simple things on an old Android tablet I had rooted.

robsmith11 avatar Mar 22 '18 13:03 robsmith11

I uninstalled "KNOX" from my samsung device to check, if that solves the problem. But still the same problem.

abinashdash17 avatar Mar 23 '18 06:03 abinashdash17

Tried to set selinux to permissive mode by

su
setenforce 0

Still no luck. Anything more, left to try?

abinashdash17 avatar Mar 23 '18 06:03 abinashdash17

After a lot of hit and trial, got some work around,thanks to @robsmith11's error identification(may not be a solution though).How to create lo n/w interface
In a su shell:
ifconfig lo:0 127.0.0.2 netmask 255.0.0.0 up
Then, in my terminal

export DISPLAY=127.0.0.2:1
xterm

and hurrah!!!
Note: Thanks to Xserver Xsdl network management system(or whatever it is called), it's listening to the new loopback network(never expected it to work with such a weird network interface setup though). I thought it's very rigid regarding networks, but it turns out however XSDL is very flexible.
