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?
(My wife is already asking me when I am going to return the reader...) |
Code:
# echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Try on pocketbook. The behavior you mention - setting stuff like backlight intensity is interesting, because it talks with monitor process (./pocketbook). This would imply that the command queue is clogged and monitor is slow to respond. A lot of stuff talks to this, and monitor also likes to snoop around the os and change behavior. Among other things, it checks if ssh is running.
