Supposing the lag is caused by suspend, I also find that changing the markers for highlighting and for page cropping can be extremely laggy. These are events that have a lot of prior touch events. Further the device sometimes fails to come out of suspend. (See this
thread about quirky power behavior.)
I remember my desktop on Arch Linux having trouble pulling the then new AMD CPU Ryzen 2600 back to maximum performance after a suspend: basically remaining at 1.5GHz instead of 3.5GHz. I had to manually adjust it:
Code:
cpupower frequency-set --governor performance
. The trouble has disappeared with newer kernels.
What would be a good approach to test this on the Pocketbook 740-2? I am reading the
Arch Linux Wiki, but can't find directly relevant information, yet. Did you already include tools in your package that could be used to troubleshoot this?
