Using the Librem Mini connected to a KVM switch, and i was able to setup a sys-usb VM which is working fine.
Temperatures are about 60°C, mostly below 60°C, if there is something CPU intens work between 60-70°C.
Been using the Mini with Qubes on it as my primary computer for about six months. Initially suspend mode worked about 60 percent of the time. Now it hardly works at all. Not a big deal though as I simply leave the computer on. Mouse movement becomes choppy after a few days of use though. Not sure what causes that. Debian 10 template stopped working three months ago. Not sure if that is a software or hardware related issue. I use Fedora as my template now. Overall works ok, but not as well as Qubes on my Librem 15.
Not that this looks like Librem Mini v1, because the current version v2 has Intel Core i7-10510U.
This is strange that suspend does not work. All Purism hardware should support Qubes well, they even test it themselves. You should ask for help on Purism forums.
Also, you can create a new topic about your Debian 10 template problem, and we will try to help.
I believe the Librem key was intefering with the suspend. I must not have had the key properly configured. I decided to do away with the key and I no longer have problems with suspend. No more choppy mouse movements either. So everything seems to be working fine now. I think the latest Qubes updates also helped.
The Librem Mini V1 has the Intel 8650U chip. I was originally using Pureboot with the Librem Mini and every time I booted the machine I would have to regenerate the TOTP and reset TPM with 4.1. Also suspend never worked. So I reverted back to Coreboot. Suspend now works better. It crashes upon wakeup “only” 50 percent of the time now. It crashed upon Restore Backup the first time I attempted. I had to reboot the system. The second time I was able to restore without an issue. Everything else including the audio, ethernet, and usb ports appear to work fine. This is my report after several days of use. On a 1 to 10 scale of usability (10 being best) I would rate the machine a 7 with Qubes 4.1.
