Hello,
I am using a dock connected to my laptop via USB C. The dock is Dell K20A001. I have my peripheral devices connected to the dock via a USB hub via one of the USB ports on the Dell dock. I have an external Display connected via the Dock using the Display port.
Sometimes (very frequently), when I wake up my laptop from suspend (i.e. pressing the laptop’s power button), the display wakes up fine but my external keyboard and mouse do not work. My laptop’s keyboard/trackpad works fine, though.
I looked at journalctl but could not find anything useful (I am not that knowledgeable about low-level kernel staff). Can anyone help me with this issue, please?
Note: I also tried Hibernate, which also caused the same problem as Suspend.
Here is the output from journalctl:

I have also executed that command dmesg | grep -i taint which revealed this info:
[ 7.151121] nvidia: loading out-of-tree module taints kernel.
[ 7.151136] nvidia: module license 'NVIDIA' taints kernel.
[ 7.151138] Disabling lock debugging due to kernel taint

[ 7.913695] nvidia_uvm: module uses symbols nvUvmInterfaceDisableAccessCntr from proprietary module nvidia, inheriting taint.
So it looks like my Nvidia card/drivers are causing the problem? I am not sure.
