Problem: The screen shuts down when I move the mouse over 3 "invisible" horizontal lines at the bottom of the screen, above the taskbar.
System:
Zorin OS 17.3 Core - the problem also occurred in Zorin OS 17.2
Hardware model: Dell Inc. OptiPlex 3070
Processor: Intel® Core™ i5-9500 CPU @ 3.00GHz × 6
Graphics: Mesa Intel® UHD Graphics 630 (CFL GT2)
Graphics driver: Intel i915
Window system: X11
Kernel: 6.8.0-52
When the mouse cursor reaches those areas, the screen shuts down, and only recovers if I move the mouse. The 3 horizontal lines cross the entire screen.
The screen only shuts down if I move the mouse slowly. If the mouse moves quickly, the screen stays on.
I changed the mouse dpi, it doesn't affect the problem. I also tested with multiple mice. The problem occurred with all of them.
I switched from Wayland to X11, the problem persists.
I tried multiple desktops, window managers, display managers, the problem persists regardless of the combination.
I tested with multiple kernels: 6.8.0-52, 6.8.0-50, 6.8.0-40. The problem occurred with all of them.
I tested multiple distributions on this hardware. All Ubuntu-based distributions tested have this problem (Ubuntu, Mint, Elementary, Zorin). I haven't tested with Debian.
I tested with Fedora instead - the problem was resolved, so it's something specific to Ubuntu (or Debian) systems.
The problem doesn't occur in Windows either, so it's not something physical, like faulty mice, cables, or ports.
The problem doesn't seem to be related to power management, I disabled all settings of this kind, in the system, and also what I found in the BIOS.
All BIOS settings, system files, drivers, applications are up to date.
Also, the problem disappears if I boot the system in "recovery mode"!
I know this isn't a Zorin OS specific problem, but I'm wondering if someone else has encountered it, and managed to fix it.
Sure, here's a screenshot, but I should emphasize, these aren't actual lines, but mouse cursor positions where the error occurs. The lines in the image are drawn by me to indicate where it happens.
Thank you, Aravisian, I'll try that tomorrow and post the outcome. Ponce-De-Leon, nothing of the sort, it's a newly installed system. But regardless, it did the same in other distributions, including live ones - all based on Ubuntu.
