Bug ID: 429559
Summary: Virtual desktops configuration module is broken and
mismanages virtual desktop rows
Product: systemsettings
Version: 5.19.5
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_kwin_virtualdesktops

SUMMARY
The virtual desktops configuration module appears to be broken with regards to
the setting of the arrangement of virtual desktops in multiple rows.
If you ask for the arrangement of virtual desktops in multiple rows, the
requirement is not obeyed and the kwinrc file is not correctly updated.
For instance if you ask to have 4 virtual desktops and you ask for them to be
arranged in two rows, using the system settings configuration module for
virtual desktops, the requirement for two rows is ignored (or you do not get
the apply button active at all after the change) and you get the 4 virtual
desktops arranged in a single row. If at this point you go again to the
configuration module, you will see that it is still set up for a single row.
This is a bug of the configuration module, not of kwin. If you edit kwinrc with
a text editor and you put the correct info in there (by going to the [Desktops]
section and by filling in the number you want at the Rows= entry, you get the
behavior you want).
This may be the same issue as in bug 421992, but I am unsure because the
description there is very brief.
The issue is seen in (k)ubuntu 20.04 (plasma 18.5), 20.10 (plasma 5.19.x) and
in manjaro 20.10 (that now uses plasma 5.20.2, I believe).
STEPS TO REPRODUCE
1. Start with a new user, so that the plasma configuration is fresh and you
have a single desktop (no virtual desktops)
2. Go to system settings -> Workspace behavior -> Virtual Desktops
3. Try to configure your system to use 4 virtual desktops arranged in 2 rows
OBSERVED RESULT
You get 4 virtual desktops in a single row and you cannot change that from the
GUI. Only by manually editing kwinrc you can obtain the two rows.
EXPECTED RESULT
You should be able to setup your virtual desktops in your desired number of
rows.
