Description grmat 2017-09-11 15:46:56 UTC
I recently upgraded to 5.38 and it broke the functionality some kwin shortcuts, e.g. "move window to next desktop". Also tried with new user, with clean configs. Downgrading kwindowsystem to 5.37 resolves the issue.
Comment 1 Martin Flöser 2017-09-11 19:15:22 UTC
what's the shortcut you try to use?

Comment 4 André M 2017-09-12 02:17:04 UTC
Looks like Ctrl+Alt+Shift+[key] are broken also, where [key] are not only arrows, but also at least Del and PgUp (e.g. logout/restart without confirmation default shortcuts), maybe any key combination using Shift+[Alt|Meta].

Ctrl+Alt+Shift+Left/Right to move window to previous/next virtual desktop

I'm having same issue after KDE upgrade to 5.38 on Archlinux
Comment 7 Eric Donkersloot 2017-09-12 20:39:42 UTC
I can confirm this one (running Arch Linux as well)

Comment 9 Daniel R. Güell 2017-09-13 08:52:12 UTC
Hi, The same here.

I can confirm in archlinux. The shortcut don't work since I update 

extra/kwindowsystem 5.38.0-1 (kf5)

Comment 10 Martin Flöser 2017-09-13 16:22:53 UTC
The bug is in kglobalaccel not in kwindowsystem.
Comment 11 zellox 2017-09-14 01:54:09 UTC
I'm having the same issue on Arch. The shortcut I'm using is ctrl + shift + spacebar.
Comment 12 Nate Graham 2017-09-14 02:14:34 UTC
Is anyone able to reproduce this on Wayland, or just X11?

KGlobalAccel has only gotten one consequential many commit since 5.37: https://cgit.kde.org/kglobalaccel.git/commit/?id=2c20ddff034e4958bf0536ca91ae9e444955305d

Wayland should not be affected. The change you mention only affects X11.
Comment 14 Lukas Jirkovsky 2017-09-14 07:35:13 UTC
Reverting the commit 2c20ddff034e4958bf0536ca91ae9e444955305d indeed fixes the bug.

Seems graesslin was right about not trusting this change. Oh, the joys of being a maintainer...
Comment 15 Eric Donkersloot 2017-09-14 12:03:25 UTC
upgraded kglobalaccel (5.38.0-1 -> 5.38.1-1)

Fixed, thanks!

Comment 17 Chris James 2017-09-14 14:40:36 UTC
Also upgraded kglobalaccel (5.38.0-1 -> 5.38.1-1) and this fixed my issue as well!
Comment 18 Nate Graham 2017-09-14 15:42:18 UTC
I don't see any new commits to the kglobalaccel repo. Are distros patching this out?

Either way, we should revert the commit until we can find out what went wrong.
Comment 19 grmat 2017-09-14 16:16:49 UTC
Can confirm it is fixed, but why?

Arch has not made a change to the package: https://git.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/kglobalaccel&id=82c50bed02e8de51c11588a2d4e2cc84e59bf7f0

They updated the version. kglobalaccel 5.38.1 has the change mentioned in #12 reverted if I understand #14 correctly.
Comment 21 grmat 2017-09-14 17:59:34 UTC
You're right. I haven't seen it (like Nate Graham) because it's not in the master branch.

Comment 22 Nate Graham 2017-09-14 18:28:59 UTC
Great, marking this as fixed, then.
Comment 23 Antonio Rojas 2017-09-14 18:46:17 UTC
It's not fixed. A tarball has been released with the commit reverted, but trunk is still broken and a proper fix needs to be committed.

Comment 25 pgkos.bugzilla 2017-09-16 08:50:53 UTC
It is now impossible to bind the Meta key to the panel's application launcher.

The Meta key does not work, and additionally it resets itself to Alt+F1 after reboot.

(Version 5.38.1-1 on Arch Linux)
Comment 26 jat255 2017-09-21 16:38:13 UTC
I'm not sure if this is related, but I cannot use the shift key to move backwards through applications now when using Alt-tab switching. Should I file this as a new bug?

Git commit 68e35f234ca7d866bcb54442d22892450d871848 by Martin Flöser.
Committed on 25/09/2017 at 15:30.
Pushed by graesslin into branch 'master'.

Revert "KGlobalAccel: port to KKeyServer's new method symXModXToKeyQt, to fix numpad keys"

This reverts commit 2c20ddff034e4958bf0536ca91ae9e444955305d.

I'm reverting as we don't have a fix yet and the next release is too
close to risk any changes. As explained in the original review request
for this feature: touching this code base is dangerous. The code is
extremely fragile.

A month of living in master was not enough to spot the severe regressions
we had. As we are now only a few days away from next release we cannot
expect to discover regressions any fix would cause. I don't really see a
solution to this problem: any change might cause issues especially in
KWin, KScreenLocker and KGlobalAccel. All of them have the problem that
the maintainer of those components is not running X11 and won't spot the
regressions. Futhermore we don't have any test cases for the complete key
handing stack on X11. We won't find the regressions. My personal
recommendation would be to no longer change the X11 side and instead all
together work on Wayland and get it ready. There the world looks better:
we have a sane input stack which is completly unit tested. The first
regression caused by the changes here was discovered by a KWin test case
for Wayland. That's the world where we can change and improve the stack.
Let X die, long live Wayland!

If someone wants to take on the task to improve the X11 stack here I
expect some serious work on the testability of this fragile stack. If we
see that the shortcuts will still match I would be way more confident to
accept a change.

Comment 29 kdeuzver 2023-08-18 05:20:03 UTC
I submited a new bug: https://bugs.kde.org/show_bug.cgi?id=473496

`Alt+Shift` does'nt works together at all for shortcuts. Neither for default nor for custom.

Despite the `Ctrl+Alt+Shift+ARROW_RIGHT` and `Ctrl+Alt+Shift+ARROW_LEFT` is set by defalt for moving windows across desktops - it doesn't works!
The `Shift` is ignored and just `Ctrl+Alt+ARROW_RIGHT` and `Ctrl+Alt+ARROW_LEFT` is triggered.
