I just did this and was able to recover closer to 100MB (now have 128MB available)… still a great improvement. Boot times don’t appear to be impacted, though compression is slower (almost 3-4x slower).

This is what I did… I currently use a refurbished Latitude 7420 with Pop!_OS as my daily driver (personal and work). Many of the Latitude, Precision, and XPS machines are actually Ubuntu certified, so you can have a high level of confidence of Linux working on them.

I’ve been using Linux on Latitudes for about 18 years and have had very little issues in terms of hardware support (although, tbf, I mainly stick to all Intel models as someone mentioned above). Highly recommended.
