My new laptop HP CR2000TU is not functioning properly with Ubuntu 18.04...
1. The touch pad not detecting
2. Wifi not working
3. The brightness change is not working
Can anyone help me to make the system work properly....
I can work with external mouse....
Yes, we may, with some hardware specifications and one problem per thread, please.
But first, why 18.04? Why not 20.04?
And before anything else, please update UEFI firmware.
As CelticWarrior already said, make sure UEFI is updated. Then, grab a copy of 20.04. It will more likely have the drivers that you need to make most, if not all, of the things work.
