Error with Screen Resolution or Mouse seetings
I have a 10yr-old Dell laptop that works just fine with Fedora 43 KDE Desktop. Last night i was typing something, and i must have accidentally keyed-in a keyboard shortcut that completelly messed up the viewing seetings of my screen. I can only describe it like this: my screen resolution looks like it is being reduced (similar to 1200x720 or whereabouts, but the actual settings are showing Full HD on Display Configuration) and windows are larger than my screen, and therefore all edges of all windows are outside of my screen. However when i move the mouse towards the required direction of any windows (i.e. top-left, or top-right) my cursor moves toward the required destination normally, but at the same time the required destination comes toward my cursor simultaneously as if it is automatically scrolling towards the cursor with just one finger on the touchpad!!! And that happens with one finger on the touchpad. Needless to say i checked the mouse properties, touchpad properties, display resolution and there was nothing wrong. I restarted the laptop and this feature remains as is despite several restarts. I also waited for an package update from Discover, i installed eveything, restarted and the problem still persists.
Does anyone have an idea what it is, and how to turn it off? It doesn’t look like it is a computer glitch, but rather a design feature of KDE for screens incompatible with the resolution of some software or sites, because it happened when i accidentally mistyped (???) by error some keyboard shortcut that i didn’t know it existed. Other than that, tha laptop works fine but all apps (Firefox, Libreoffice, Dolphin etc) are all oversized, all windows are way too big (low res?) and all edges of windows are outside of the visible area of screen.
Any assistance will be very much appreciated.
