Hi, @Precious
Hmmm... Does your old 64-bit PC - that is running Ubuntu MATE 22.04 LTS ("Jammy Jellyfish") - have an "Intel HD Graphics" as its "Graphics card" (also known as "Video card"), by any chance? If you don't know if that's the case or not, you can run "MATE System Monitor" (in the Ubuntu MATE Menu, search for MATE System Monitor or navigate, from the Ubuntu MATE Menu, to "System Tools -> "MATE System Monitor"). When the "MATE System Monitor" window opens, in the first (default) tab ("System"), check what appears in the "Hardware" section, and specifically in the "Graphics:" line of that Hardware section.
In case you find that your PC does have an "Intel HD Graphics" card: here in the Ubuntu MATE Community, in another older somewhat similar discussion, started in September 2022, by @Ygor6889 (Ygor Oliveira Silva) - "Ubuntu Mate 22.04 auto ending Sessions when I do something specific" - the user @esan_br (Elias Andrade), that has a "Dell Latitude E6410" which also has an "Intel HD Graphics" as its Graphics card, solved the issue that was also happening to him, in "Ubuntu MATE 22.04 LTS" ("Jammy Jellyfish") by:
1 - Creating a file "/etc/X11/xorg.conf.d/20-intel.conf"
2 - Putting the following content in that file:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "TearFree" "true"
EndSection
3 - And then rebooting the computer.
Link to that post from @esan_br that he wrote on 1st October 2022:
In that same discussion, the user @Ygor6889 (Ygor Oliveira Silva), that started that topic and that also has a computer with an "Intel HD Graphics" video card, says that @esanbr's solution worked for him as well:
So, @Precious, if your old 64-bit PC does have an Intel HD Graphics card, then I suggest that you try @esan_br's solution, see if it works for you and then reply again in this same topic where we are now, to tell if that solution also worked for you (or not).
Good luck!
