Bug ID: 391034
Summary: KWin fails querying root window property
_NET_CURRENT_DESKTOP
Product: kwin
Version: 5.12.0
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: bharadwaj.raju...@gmail.com
Target Milestone: ---
When a program queries KWin for the root window property _NET_CURRENT_DESKTOP,
fails to respond correctly.
According to the FreeDesktop spec on "Extended Window Manager Hints",
specifically the section "Root Window Properties (and related messages)", at
https://specifications.freedesktop.org/wm-spec/1.3/ar01s03.html, window
managers _must_ return an integer between 0 and (num_desktops - 1) in response
to a query for this property.
Expected Behaviour:
$ xdotool get_desktop
0
Actual Behaviour:
$ xdotool get_desktop
XGetWindowProperty[_NET_CURRENT_DESKTOP] failed (code=1)
-1
Notes:
If one switches workspaces/desktops and tries again, it begins to work.
However, after a reboot or just waiting for some time, it agains starts
failing.
Getting the _NET_NUMBER_OF_DESKTOPS property works:
$ xdotool get_num_desktops
4
