Apologies, let me rephrase, touchpad was working from the start, is also still working, but very stuttery, almost like there are driver issues. Almost no recognition when tracing your finger over the pad.
Awesome, then issue resolved for the keyboard!
However, might it be that the lenovo " Buttonless glass surface multi-touch touchpad, supports Precision TouchPad (PTP)" has some sort of proprietary driver which makes it hard to interact with linux?
Well, my solution was short lived... keyboard died again after a sleep mode.
I did not have synaptics installed, just installed it, now going to reboot.
I know exactly what the OP is going through, I've had both issues. With my old workstation computer that Zorin is on, the touchpad can by stuttery/twitchy just like the OP has said. And on my MSI gaming machine. My Corsair K95 Platinum mechanical keyboard, doesn't usually power up properly with the computer on the first try, and requires a restart, or further restarts, until it does connect properly.
We can't simply write these issues off as distro specific. Cause both OS's are based on Ubuntu, so all I am saying is. If we figure out what is going on with the OP's machine, the results of that, could also benefit me, as well as other's.
So I will be watching this thread closely. Also, how are things going since you installed Synaptics?
Alright, we got the keyboard working, however the keypad is still forming an issue, I'm going to scour around the interwebs for a bit and see if I can find something.
If anyone has any suggestion regarding this issue, feel free to share
Current attempst:
Adding pci=nocrs to /etc/default/grub did not provide any changes.
It can be hard to tell.... But it is no big deal. All you need to do is install the older kernel, then boot into the recovery mode, select that kernel, then boot from it. Then test the results. If it doesn't work out, just reboot and the computer will boot into the higher kernel.
Fellow ZorinOS users, and who knows maybe someone in the future, at this time Lenovo does not like the 5.11 kernel. A downgrade to 5.8 seems to resolve ALL issues that I have mentioned:
Non working keyboard
Bad working touchpad
Weird horizontal screen flickering when scrolling/ moving the mouse
