This is my first post. I have used this site to fix many (if not all issues) I have had over the years with my Linux installations and now I am stumped.
I am noticing a lot of lag with the GUI especially when using the Cinnamon Main Menu and scrolling through the applications list and/or using the search in the menu. This lag also continues through in Firefox (Both Quantum Dev 68.0b(4 and 7) and Quantum 67 ) and other applications.
My main HD is an m2 that has the clean install of Mint 19 (installed 2-3 weeks ago - I didn't notice the lag to begin with but now after using it it is prevalent). I have a 2nd internal SSD that I store my data on (this HD also has a previous installation of Linux mint 19.1 that I am yet to uninstall) and an external mechanical HD that I use for Timeshift and CrashPlan backups.
I have search for the last few weeks to find a solution to no avail.
I believe I have done all the "usual" performance checks / tweaks e.g. turning off all windows effects etc.
Any help is greatly appreciated.
P.S. I am sorry if I havn't posted this in the correct category, or, if I haven't given enough information about the question. If you need any more information let me know!
Thanks in advance.
