Ni hao and welcome. However, if we're talking software, gNewSense is probably
more stable than Trisquel at least based on their lineage (gNewSense is based
on Debian and Trisquel on Ubuntu).
One way to find out if certain hardware works is to walk to computer shop
with a Trisquel live CD or USB and try out the machines, if they allow you to
do that. https://en.wikipedia.org/wiki/Live_CD
Besides that you can try to gather general compatibility trends from
http://h-node.org However, note that this information cannot be trusted
because manufacturers swap chipsets without informing the buyer.
