Description of problem:
When I run startxfce4, it fails with the error 'Unrecognized option: --'.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run startxfce4
X fails to start
X and XFCE4 start.
There is a question asked on Ask Fedora about a similar problem, in Spanish.
If I run `xinit /usr/bin/startxfce4 -- :0 vt1` it starts XFCE4 correctly.
Can you file this upstream or would you like that I do?
You can file it upstream. However this could be Fedora specific as startxfce4 was working fine on Arch as of a week ago. Can you reproduce this on your system?
I have not had the chance to try this. I will check and report upstream if needed.
I filed the bug upstream myself - id 15618.
The problem is Fedora specific. It is because of a Fedora patch  conflicting with an XFCE patch . I also applies for the recently released xfce4-session-4.13.2-2.fc30.x86_64. Further discussion can be found on the XFCE bug tracker .
I will fix this in the next update.
The problem persists in xfce4-session-4.13.3-1.fc30 that has been pushed to the Fedora 30 stable repository.
This message is a reminder that Fedora 30 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora 30 on 2020-05-26.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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' of '30'.
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 30 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 30 changed to end-of-life (EOL) status on 2020-05-26. Fedora 30 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no longer maintained, which means that it will not receive any further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.
