Hallo
If you canât get Ubuntu-Mate or one of the other âlightweightâ Ubuntus to run well have a try with âantiXâ (https://distrowatch.com/table.php?distribution=antiX). I installed it last year on an IBM notebook (and I donât mean Lenovo) that was bought in early 2005. The desktop is very simple but it runs well. If you need to get that hardware running and canât upgrade the RAM this may help you.
