Description Nikolaos Drosinos 2016-12-16 08:26:01 UTC

Description of problem:

I'm using sawfish window manager configured with a 4 * 4 viewport grid, and have enabled flip-viewport both when moving the mouse as well as when moving a window to all four screen edges. After upgrading from Fedora 22 to Fedora 25 via dnf upgrade, moving a window across the edges results to transitioning to a non-deterministic viewport, i.e., moving a window to the right edge of viewport (0, 0) might cause a transition to any of the vieports (1, 0), (2, 0), or (3, 0) (instead of always transitioning to (1,0)). flip-viewport works ok when just moving the mouse to a screen edge. I have disabled wayland in /etc/gdm/custom.conf (though I don't think that sawfish is wayland-enabled, anyway). I also have a feeling that d-bus is not working correctly, as I had to disable Dbus server on terminator terminals, since opening one would move focus to a random viewport (though the terminal would be opened on the requested viewport). Also, on the sawfish rootmenu (middle mouse click) terminator appears on the window list with a blank group name, though this is minor and possibly irrelevant.

Version-Release number of selected component (if applicable):

sawfish: 1.12.0-1.fc25.x86_64

How reproducible:

Every time.

Steps to Reproduce:
1. On sawfish, configure a 4 * 4 viewport grid and enable flip-viewport for all edge actions.
2. Open any application window.
3. Select it with the mouse and move it to any of the four window edges.

Actual results:

flip-viewport will transition to a random viewport.

Expected results:

flip-viewport should transition to the neighboring viewport.

Comment 1 Fedora End Of Life 2017-11-16 18:40:15 UTC

This message is a reminder that Fedora 25 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 25. 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bug reports from releases that are no longer maintained.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 '25'.

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 25 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.

Comment 2 Fedora End Of Life 2017-12-12 10:37:14 UTC

Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 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
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
