What can I do to address mouse cursor vanishing under Linux Mint 21.2 (“Victoria”)?

I have a mouse cursor intermittently failing on me. My search did not find anything in questions here, but https://forums.linuxmint.com/viewtopic.php?t=377066 did seem to indicate the same problem, but without pointing out a solution that works on my computer.

The recommended solution was to create /etc/X11/xorg.conf.d/20-nouveau-swcursor.conf with content:

#--makes mouse cursor re-appear
Section "Device"
    Identifier  "Device0"
    Driver      "intel"
    Option      "AccelMethod" "uxa"
    Option      "SWCursor"    "on"
EndSection
#--

I changed the Driver to "i915" after running inxi -Gx:

Graphics:
  Device-1: Intel 4th Gen Core Processor Integrated Graphics vendor: Mitac
    driver: i915 v: kernel bus-ID: 00:02.0
  Display: server: X.Org v: 1.21.1.4 driver: X: loaded: modesetting
    unloaded: fbdev,vesa gpu: i915 resolution: 1920x1080~60Hz
  OpenGL: renderer: llvmpipe (LLVM 15.0.7 256 bits)
    v: 4.5 Mesa 23.0.4-0ubuntu1~22.04.1 direct render: Yes

However, this does not appear to have resolved the disappearing mouse cursor.

How can I request that the mouse cursor not disappear randomly, or perhaps not disappear at all?

Thanks,
