I bought a new gaming laptop for work but as always i would like to run Ubuntu on it. As i’ve tried Ubuntu 20.04LTS on a lived-USB, the touchpad doesn’t seem to work. I decided to install it completely and the touchpad worked after kernel upgrade.
1. Download Ubuntu and create lived-USB installer
2. Since touchpad is not working, just use keyboard shorcuts for installing Ubuntu 20.04
3. After successful installation, Open “Software Updater” and click “Partial Update”
4. Touchpad should be fixed, Kernel should be updated to the latest On Linux 5.11.0-38-generic #42~20.04.01-Ubuntu
NOTE: On Linux 5.11.0-38-generic #42~20.04.01-Ubuntu, the touchpad should work but:
- Brightness (Fn+F5 and Fn+F6 keys) wont.
To fixed the brightness issue follow the steps below:
- Edit /etc/default/grub and add parameter :
GRUB_CMDLINE_LINUX="amdgpu.backlight=0"
2. Execute update-grub
update-grub
3. Reboot the laptop, backlight control should work after
