I’ve been using Solus GNU/Linux with the KDE Plasma (Wayland) desktop environment recently on my Desktop PC and my two laptops. While doing a few projects on my older laptop PC today, I noticed that when I minimize a window, it apparently disappears into oblivion, no highlight on the panel icon and no way to raise the window so I can continue my work. Not only that, but when I have one window open and I open another one that covers it, I have no way to bring the covered window to the top so I can continue working with it.
After a few Internet searches, a bit of reading, and some re-configuring I was easily able to fix my problem. Somehow (probably my fault) the Icons Only widget got removed from the panel. All I had to do to fix my problem was add it back on, pin the apps I want to see on my panel to the task manager, and remove them from the panel. I had seven apps pined to the panel, so all I had to do was remove them (one at a time) from the panel and pin them to the task manager.
If you use KDE and you have a similar problem, you can check to see if the task manager is installed by ALT+Clicking any icon in the Applications menu. If there is no option to ‘Pin to Task Manager’, it’s not installed.
To install the task manager widget, ALT+Click an empty space on your desktop and select ‘Add Widgets . . .’ from the context menu and the Add Widgets dialog will slide out from the left side of your screen. Enter ‘task’ in the search field at the top of the dialog and the list of widgets will be reduced to two task manager items. I clicked on the ‘Icons Only Task Manager’ item and it was installed to my panel.
I’m adding this item to the Discussion category. If anyone thinks it fits better elsewhere feel free to move it
I hope this helps others,
