Ground floor apartment here. Winter is hell, the storage area in the basement below us is unheated, so the apartment feels like Siberia. Summer is glorious though, nice and cool even in the middle of the most brutal heatwave.

Not really. Default drivers should work just fine. If you want to make sure they’re installed and running, run the following in a terminal:

glxinfo | grep Mesa

If you have any output, you have Mesa. It’ll tell you what version you have as well.
