Samsung nc110 with 12.3

I have a Samsung nc110 which happily was running 12.1. I’ve upgraded to 12.3 and have a number of issues:

  • It runs hot - CPU freq scaling not working?
  • Volume & brightness up & down doesn’t work
  • (Microsoft) wireless mouse has persistent “blackouts” - just stops working. Never works after restart from hibernate.

All was OK on 21.1

Any advice / guidance about how to get it to work?

Thanks
David

I’ve found half an answer. I’ve installed samsung-tools from the buildservice maintained by Paul Artsishevskiy (polter), and have added acpi_backlight=vendor to the grub command line.

That just leaves the overheating and the wireless mouse disconnects to fix.

p.s. the wireless mouse disconnect is fixed reliably by unplugging the little usb sender, and plugging it into another usb port.
