I had installed Debian on an Acer Aspire One Laptop. It has a 32-bit Intel Atom CPU with just 1GB of RAM. I obviously can't run it like a usual desktop anymore, it's way too slow.
I tried it to connect it to my TV with HDMI to create some sort of "Smart TV" setup, but that didn't work out because I can't even play 1080p videos on VLC with it smoothly.
So.... What now? Can I only use it for headless stuff like pihole, nextcloud, etc. now?
Is there any hope left for my unsuccessful "Smart TV" contraption?
You can try turning it into a retro gaming station by installing RetroPie. Some have got it working on as little as a Pi Zero. Of course, that laptop won't be able to run the more demanding emulators.
Probably or probably not. The only way to find out is to try. I've installed RetroPie on a number of old laptops; the oldest one being a 2002 Toshiba laptop. I got to play GBA games just fine with it.
