You-Cheng, i also tried removing pci=nocrs and rebooting and it did not work either.
I would like to try https://launchpad.net/~vicamo/+archive/ubuntu/ppa-1881322, should I delete all the grub parameters that i added? To add further information: - With the parameters I currently have, and with Mouse Click Emulation set in "Area" (in Tweaks), the right mouse button and middle mouse button does not work (In xev i can see that all are mapped to button 1) but the gestures as two finger scrolling work fine. - With Click Emulation set in "Fingers", xev shows button 1, button 2 and button 3 with one, two and three fingers, respectively. - The Option "Disable Touchpad while Typing" does not work with any of the previous configurations. Also, I think this is unrelated: - Sometimes when I boot ubuntu, the sound does not work, even the icon in the sound settings (top right corner) does not show, and the volume with the Fn keys does not change. - When you try to open an app (e.g. Firefox), a folder or a terminal, it needs around a minute to work for the first time, then you can open anything normally. - When I try to shutdown or restart, it shows a recurrent message "[ 56.603594] snd_hda_intel 0000:00:1f.3: No response from codec, resetting bus: last cmd=0x202f8100" - The initial number rises (e.g. the second message is [ 57.607631]) and the hexadecimal number also changes. - I have to force the shutdown. It usually requires one restart to fix, but sometimes i get in this situation two times in a row. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881322 Title: Touchpad not detected in 'Lenovo V15-IIL model 82C5' after installing Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1881322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
