82A4 IdeaPad Slim 7 14IIL05 Just arrived today.
Clean install of Windows 10 2004, everything works fine.
Installed Ubuntu 20.04.1, no trackpad, graphical artifacts like crazy. VERY sluggish.

Installed 5.9 after another forum member mentioned adding the grub arguement 'GRUB_CMDLINE_LINUX_DEFAULT="pci=nocrs quiet splash" but only after upgrading to 5.8+
This didn't help
