Public bug reported:
In the live-boot USB stick of Ubuntu Desktop 20.04 LTS:
My mouse pointer does not visually reach the left edge of the screen.
Logically the pointer functionality does reach the left edge, in the
sense that it can select and copy text that extends to the left edge,
but the pointer cannot be viewed performing this action; the displayed
pointer stops (appears frozen) about two millimeters from the left edge.
The pointer reaches the upper, lower, and right edges of the screen
without any problem.
My mouse and screen are brand new. My computer is 5 years old (launch
2016, purchase 2019).
I have the same problem with my Linux Mint (Cinnamon and Mate desktops),
which is based on Ubuntu. I perform regular updates to the system. The
file /var/log/Xorg.0.log does not show any errors or warnings related
to the mouse.
The problem in Linux Mint persists even if I change:
- Screen resolution
- Theme
- Windows settings (Focus mode)
- General settings (VSync method, Compositing)
- Mouse acceleration and sensitivity
- Disabling of all Effects
Note that there is no problem with the mouse pointer with a live-boot
USB stick containing Linux EndeavourOS.
