Dell Latitude D530 - Install Linux

Attempting to resurrect old laptop with 2GB RAM and 120 GB hard drive

1. Absolute Linux - worked okay until I used control panel to update and upgrade. Then Gslapt stoppped working.

2. Thought maybe 32 bit was the problem, so installed Q4OS. Screen glitchy and frequent unwanted refreshes

3. Installed Linux Mint and so far so good. All I want is to keep Firefox updated, so I can distract myself with NetFlix.

4. I have other laptops for running GNU Radio, CubicSDR, Aircrack-ng and WiFite.
