This may help some folks who want to use Okular but also have their PDF files reopen between restarts. You can call saveokular.sh from cron and some other tricks so this is all seamless:

$ cat /usr/local/bin/openokular.sh

#!/bin/bash

Check if the file with paths exists

if [ ! -f ~/.okular_open_files.txt ]; then

echo "No saved PDF paths found."

exit 1

fi

Open PDFs in Okular

echo $1 >> ~/.okular_open_files.txt

sed -i '/^$/d' ~/.okular_open_files.txt

cat ~/.okular_open_files.txt | xargs -d '\n' /usr/bin/orig_okular &

$ cat /usr/local/bin/saveokular.sh

#!/bin/bash

if pid=$(ps -C orig_okular -o pid= | sed -e 's/\s//g') && [[ -n $pid ]]; then

ls -l /proc/"$pid"/fd | grep '.pdf' | awk -F ' -> ' '{print $2}' > ~/.okular_open_files.txt

fi

For the Slideshow option on Desktop Settings / Wallpaper, and the user is using the Random order and a new file appears in one of the wallpaper folders, make that image the next one to show.

Hello,

I'm trying to get kwin-wayland to use just a part of my monitor, with X11 I did it with xrandr, but I'm not sure how to best do that with Wayland.

I have a messed up monitor and using only the bottom right corner makes it more acceptable, but for that I need no pixel lit on the top left corner.

Thanks for any hint!

I'm a new user of KDE having recently installed OpenSUSE Tumbleweed. I'm happy with most of it, but I have one big annoyance: the incessant appearance of tooltips and them not going away when the mouse moves. This is on X11, not Wayland.

I often have windows overlapping or next to each other. When switching windows and moving the mouse, I move over an inactive window to the active one. A tooltip then appears for an item of the inactive window that is in the background. In my opinion it shouldn't, because the window is inactive, but it does. What is even more annoying is that the tooltip will remain on screen, over the active window, even when I maximize the active window. It will be displayed on top of it. It often happens that I fullscreen a video only for there to be a tooltip from an inactive window displayed over it, or a tooltip from the program that spawned the fullscreen video.

The only way to remove the tooltip is to activate the inactive window, move my mouse so the tooltip disappears, switch to the previous window again and then very carefully make sure I don't trigger any new tooltips in the inactive window. I'm not always successful at this, which means I have to repeat this process. This seriously impacts my enjoyment of the system.

I have already tried some solutions, disabling tooltips for titlebars in the System settings/Appearance/Window Decorations/Titlebar Buttons section and unchecking the "Display informational tooltips on mouse hover" checkbox in Workspace behaviour. Signing out and back in and rebooting have no effect. The options just don't do anything, except remove the window preview tooltips from the Task Manager, which I do need to navigate between windows. These previews should not be classified as tooltips in my opinion, but that's another matter.

What are some other options I could try? Even though I appreciate tooltips sometimes to help me learn about this new system, at this point I'd rather there be none at all than having to deal with this annoying behaviour. Ideally I would like to disable tooltips for inactive windows, or conversely only show them for active windows. If that's not possible however, I'd like to learn how to disable them completely since the options in settings have no effect.

Some software information:
KDE: 5.27.8
KDE Frameworks: 5.110.0
Qt: 5.15.11
Kernel: 6.5.6-1-default (64-bit)
Graphics platform: X11

Thanks for any suggestions.
