Public bug reported:
Running Ubuntu 18.04 on Dell Latitude-E5420 with 3.7 GB RAM Gnome 3.28.2.
Updated from Ubuntu 16.04. Applications freeze after about an hour continuous
use, while applications are running RAM use increases gradually typically from
about 55% to 100%.
The solution is to use lightdm as the display manager. Default Ubuntu DE
appears to work fine with lightdm.
I tested other DEs with gdm3 and the same problem was present. The problem has
been reported in forums
https://ubuntuforums.org/showthread.php?t=2390915 with a number of users
reporting that the solution is to use lightdm,
