I have a 2008 HP-2133 laptop machine running 32-bit Ubuntu 16.04. The machine has been running satisfactorily for several years, the only chronic glitch being a loss of speaker sound sometime after the 16.04 installation. Also,
Unity no longer ran and I have been running
Xfce. I have delayed upgrading to 18.04 because I have always had difficulties with OS upgrades as support for my hardware dwindled. Of course, 16.04 reached end of life in April 2021, meaning no further support for that version....
