S15pup 64, 22.02
Sony Vaio, Legacy Boot, originally Windows 7,
The screen runs at full brightness how can that be fixed the function keys f7 and f8 don't change the brightness - they don't in Windows 10 either but there is a way to do it. They do work on Debian XFCE.
Alternatively, I could use another Pup. But the Debian and the Ubuntu based ones don't start up.
