Peroxide and then hypochlorite bleach. Not at the same time. There are products that contain them if you can’t get them neat. In fact I recommend those.
Try the peroxide first. Dilute as necessary. Wipe or spray on. Leave it on for a while to loosen anything and everything it can. After a while fill with hot (60-80C) water, but beware of thermal shock. Leave to stand until warm, not hot. Try to clean the glasses as best you can. This may be all you need.
If not, try the bleach. Same steps, but make sure you’re in a well ventilated area. I’ve found that while it stinks up the place, the mould just peels right off and into the hot bleach solution.
If the glasses smell of bleach afterwards, fill with warm water and leave for a day or two. Repeat as necessary. The bleach will dissipate eventually.
Sounds like a job for a USB trial run on a rainy weekend when you’re not doing anything else.
Nvidia supply OEM drivers for the Debian family (Debian, Ubuntu, Mint), if not others, assuming the open-source drivers don’t cut it for you. Microcode updates are released for both Intel and AMD.
You’ll probably run into issues with some games. Things are getting better on Linux, slowly and steadily, but many games are written specifically for Windows with no Linux port available. Steam’s store, for example, shows which games are SteamOS compatible, which usually means they’ll run on Linux too.
For other games it’s worth checking the Internet - e.g. www.protondb.com to see if anyone else has a particular game running under Linux. You’re probably aware that there are programs that attempt to provide some layer of Windows behaviour that form part of the solution. Some of the solutions may or may not involve command line use.
