Create legion-linux-onresume.service

[st0nie]

Some modifications, such as the changes made by ryzenadj, cannot be preserved after the machine goes through the suspend-resume cycle. Therefore, we can create a file to allow the Legion service to automatically start once the machine resumes.

sudo mv this_file_path /usr/lib/systemd/system-sleep/legion to make it working require systemd, of course tested on my machine

Now I create legion-linux-onresume.service and it seems better Just enable the service,legion-linux will auto restart on system resume

[st0nie]

The reason why I use restart instead of try-restart is that legion-linux.service will be inactive after a while, and try-restart only restart service which is active

That why I noticed some times systemd was degraded and the service failed to start. Thanks to find a solution I will just need to do some changes to the packaging.

IDK whether the fancurve-set will preserve its modification But changes made by ryzenadj will 100% lost after resume

We can also introduce a timer to ensure the cpu tune is working

I giving a look now and my service was failing because I change to a kernel without the kernel module install. This seems to be a bug only with ryzenadj since the fan curve mantain after a suspend.

Well I also thinking of use the legion_cli.py as deamon instead of a seperate bash script, but we can add this systemd service in the mid time. The ryzenadj support just exist because some of cpu limit stuff in the gui dosen't work in some older model, so user can use ryzenadj to also set cpu option (and ryzenadj have more option), but it can be edit to other tool if you are using intel.

legion-linux.service as a daemon is probably better than now Now this is a script and we cannot make sure it is really working after we exec it. If it is a daemon, we can do some check after /sys/firmware/acpi/platform_profile changed and or pluged off the AC After all, daemon is simpler for user, they just need to enable the service, and legion-linux daemon do all the things

just a quick note also work in /usr/lib/systemd/system/legion-linux-onresume.service
