I’m new to Linux. I just got a Lenovo IdeaPad 3 i3 processor, 4G RAM, 256G SSD. How do I update all the computer drivers like touchpad? Not all hardware seems to be detected.
Can you please open Software & Updates from your app menu. Ensure that in the first tab, "Software restricted by copyright..." is checked ON.
Then open a terminal with ctrl+alt+t and enter into it:
sudo apt update
That command ensures that you are searching the APT for all the latest packages.
sudo apt full-upgrade
This command will upgrade all packages, even if deletion of the old packages is necessary in order to do so. The other command is sudo apt upgrade or you can use sudo apt dist-upgrade - this till upgrade only the packages that do not require deletion of the old packages.
Once this is complete, please reboot and test. IF you still need help, then you can start a thread for each bit of hardware that needs further attention.
