Red Hat Bugzilla – Bug 1302350
Cannot start graphical apps anymore sometimes, error msg is "No protocol specified" and "Connection refused :0.0"
Last modified: 2016-12-20 13:15:00 EST
Description of problem:
When I run fluxbox, I sometimes cannot start graphical apps anymore (not even xterm). When I have a xterm open and try to start it from there, I get the error messages "No protocol specified" and "Connection refused :0.0"
Version-Release number of selected component (if applicable):
Randomly. I could not figure out so far when or under which circumstances this occurs.
Steps to Reproduce:
1. Start fluxbox after boot and login.
2. Open some graphical apps or just xterm.
3. After a while, I cannot start any graphical app anymore. After rebooting, it works again (at least for a while).
Cannot start any graphical app after a while in fluxbox sometimes.
Should be able to start any graphical app for the whole fluxbox / X session.
The machine - a Lenovo E330 - was upgraded from FC20 to FC 23 (FC20->FC21->FC22->FC23) a few days ago.
The only way to get a normal behavior seems to be a reboot.

X log file
$ uname -a
Linux localhost 4.3.3-301.fc23.x86_64 #1 SMP Fri Jan 15 14:03:17 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
$ rpm -qa | grep fluxbox
The X version is 1.18.0-2.fc23.
After today's 'dnf update' (which included a kernel update to 4.3.3-303.fc23.x86_64), the error message changed to:
"Invalid MIT-MAGIC-COOKIE-1 key
Unable to init server: Verbindung ist gescheitert [Connection failed]:Verbindungsaufbau abgelehnt [Connection refused]
Error: cannot open display: :0.0"
It is now enough to restart fluxbox, so rebooting is not necessary.
And it also became an almost permanent issue, which makes the machine more or less unusable after a short while.
Is there anything I can provide with? Other logfiles or more information? It happens pretty often and is very annoying.

Fluxbos crash - extract from journalctl
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
