Black Screen with Movable Mouse Pointer after Logging into my Xfce Session in Linux Mint 22 Wilma

Reboot/Retry

Sometimes this issue is only erratically reproducible, and you might be lucky to get a working session at least.

Remove obsolete Intel Video Drivers

Xfce forum admin suggested to remove the driver package.

The kernel has built-in intel driver support that is more recent than the actual driver package and better supports newer intel graphics chips.

sudo apt remove xserver-xorg-video-intel package && sudo reboot

If the drivers are not obsolete, revert/reinstall using sudo apt install xserver-xorg-video-intel.

Disable Screensaver and Update Software

switch to a non-graphical console using Ctrl+Alt+F1,
if there is no cursor, try typing any key to make a prompt appear, and
log in,
remove the blackbox screensaver and update kernel and software:

sudo apt remove blackbox
sudo apt update
sudo apt upgrade

After a successful upgrade, use Ctrl+Alt+F7 to switch back to the graphical desktop session.

So far, so good. Problem solved, next startup without problems. However, the next day, the problem occurred again. I retried the same solution/workaround, but still only a black screen with movable mouse pointer after Ctrl+Alt+F7.

Start X session explicitly in a console session:

switch to text console using Ctrl+Alt+F1,
as there was no cursor, type any key,
log in at the login prompt,
ensure software is up to date: sudo apt update && sudo apt upgrade
explicitly start the graphical system: startx or startxfce4
switch back to the graphical desktop session using Ctrl+Alt+F7
type or click anywhere and wait for the desktop session to initialize.

This is generally not a good idea.

Killing running startx, startxfce or lightdm processes isn’t either.

Cons:

two conflicting X sessions
respawning apps with no additional debug information

BIOS/Kernel Fixes

update UEFI BIOS
upgrade kernel
downgrade kernel
switch to default kernel
switch to vendor-provided kernel (e.g. 6.11.0-120029-tuxedo #29~24.04.1tux2)

find and fix potential configuration errors or incompatibilities

see ~/.xsession-errors
- delete or rename existing error file to remove irrelevant noise
- reproduce the error
- check the file again: tail ~/.xsession-errors
