Thanks Ted. I appreciate the info and the advice to hold off. I too have read that some graphic cards can cause lock-up. I'll leave all alone. I'll upgrade, if anything is now upgradable since the install is so recent. Still.... Have a great day! On 6/7/20 10:00 AM, Ted Pomeroy wrote:

Brian, Yes, wait on taking action. Try to identify the problem. Also, I recommend staying clear of EFI partition for now.  It is for compliance with the UEFI  standards for hardware and kernel boot. You can read the Wikipedia.com article. I have had to adjust the EFI boot order, but only on certain machines. If you boot and login okay no changes needed. So, right, plenty of ram, more swap might be desirable, but seems unnecessary. I would make it a habit to run and read 'top'  on a regular basis to see what is running and what is using ram. Virtual memory is not an issue. In top Shift+e changes the units for ram to make it easier to interpret. Also look at idle(id) and waiting(wa) percentages. I have found these interesting and instructive. Even after closing Firefox and then starting top, I find it takes several seconds to get idle up to 96% or so. So, try to re-create or better identify the series of events that lead to freezes. Have you read the release notes? Some graphics cards are a boot up issue, and the new kernel is different from previous ones. You might roll back if you have an option during boot, to get to the lowest kernel number. Once in awhile new kernels leave off support for older parts. or special graphics cards. Audio and wifi not likely to be the issue. Keep up and join us at the next NMGLUG if you can. Thank you, Ted P
