Wayland, kdocker,QT_QPA_PLATFORM=xcb kdocker, failure

English Applications

Since one month or two, my solution to execute kdocker with wayland fails. The app is not minimized in the systray of KDE only in the task bar.
Perhaps something changed with wayland, KDE, Chrome or anything else, but what ?

The previous solution to lauch kdocker was :

QT_QPA_PLATFORM=xcb kdocker

see [howto], wayland, using kdocker

Do you know the statement to launch kdocker with wayland with success ?

Thanks

That was not a solution, since it makes kdocker not run on full Wayland

Some info.

I launch a vbox machine and with success I minimize it in the kde systray with the statement :

QT_QPA_PLATFORM=xcb kdocker

Here is the script

sleep 50s

bash -c 'VBoxManage startvm Windows_11_24H2_Pro --type headless & '

sleep 20s

bash -c 'rdesktop -g 1919x950 -N -M localhost &'

#bash -c 'rdesktop -r sound:local -u <user mail> -p <user pwd> -g 1919x950 -N -M <ip address> &'

# minimize the rdsktop window in the systray

while [ true ]
do
   sleep 5s
   status=$(wmctrl -l | grep "rdesktop")
   if [ "$status" != "" ] ; then
      break
   fi
done
WID="$(wmctrl -lx | grep "rdesktop")"; QT_QPA_PLATFORM=xcb kdocker -qtw "${WID%% *}" -i ~/.local/share/icons/hicolor/32x32/apps/chrome-hnpfjngllnobngcgfapefoaidbinmjnm-Default.png &

The difference when it fails is when the app I minimize is a Chrome web app.
Something in Chrome changed.

I’m not a Chrome user, but can’t it run as a native wayland app these days?

5

Another info.

This worked with Chrome web app with Wayland till one or two months. I was able to minimize in KDE systray any Chrome web app with the following statement :

QT_QPA_PLATFORM=xcb kdocker

I’ve never used a system tray utility, but wondering if wkdocker might be a suitable replacement?

thanks

It seems there is no command line.

I sent a wish

8

Anybody knowing a tool which simulates the keyboard typing ?

You should start a new topic for this. ^^

I wonder if the problem is :

with recent change of Chrome we can’t access to the title of the title bar with

wmctrl
11

Another idea.

With

QT_QPA_PLATFORM=xcb kdocker

we launch kdocker in an X11 environment.

Is there an equivalent for Chrome ?
