Help out a Noob please! AK620 Digital Pro

[jgor9061]

Hi everyone,
I've recently built a new computer with an AK620 Digital Pro, and wanted to escape the Windows ecosystem (latest Linux Mint Cinnamon). I'm trying to get your solution to work, and when I follow your installation instructions (download the latest version - 0.7.3 alpha) I get to the stage of trying to make it executable with your terminal instruction, and receive the following message:
"chmod: cannot access 'deepcool-digital-linux': No such file or directory"
I also tried right-clicking on the file and in Properties->Permissions, clicking on "allow executing file as program", and nothing seems to work there either.
The file is currently in my Downloads folder - do I need to move it somewhere else? Do I need to download the other two files (the .zip file and the .tar.gz file?)
Is it not running because I haven't installed the zenpower3 driver you recommend? I'm running a Zen5 CPU if that has any bearing on the situation.
I really appreciate your patience with me - I've literally just jumped into Linux on a whim with this new computer, and my web searches asking why I can't make this file executable aren't proving fruitful.

Hi. You've downloaded the correct file. The archives (zip, tar.gz) both contain the source code used for building the executable. Since you cannot find the file, it might be that you're running the command from a different folder.
If you're not yet familiar with the terminal:

1. Print the working directory to check you're at the right place:

pwd

2. List files / folders in the current directory with details to check permissions:

ls -l

If you see x, execution is enabled:

...
-rwxr-xr-x  ...  deepcool-digital-linux
...

More information about permissions

3. If you can see the file deepcool-digital-linux, but without the x, make it executable:

chmod +x deepcool-digital-linux

4. Check the permissions again if needed with the ls -l command.
5. Try running the executable:

./deepcool-digital-linux

Ok, so I ran the command, and got the following error message:

After doing some googling, I ended up using journalctl _PID=854 to try and see whether that would show me more information, but it didn't give me any more information than what's above. Looking at your command vs what I tried, I think I can see why it didn't give me anything new...

Now, being as clueless as I am, I found my way to a discussion on Stack Overflow (I know, dangerous to poke around there with my low level of knowledge) where with a similar error, they said "The solution was to specify in the new .service what user to run it as", and added the following lines in the .service file under [Service]:
WorkingDirectory=/home//
User=

I haven't gone and tried it because I assume if that was the solution, there would have been more people than I having issues getting this to work - I'm guessing I'm just that special.

Potentially silly question - does the .service file need to be executable as well?

I had very little time to look into it, but this error message triggers when the program has no access to the /sys/class/powercap/intel-rapl/intel-rapl:0/max_energy_range_uj file, which serves as an offset value for the CPU energy (power consumption) readings.

It seems that the file is not yet available (or readable) during the boot process, only after logging in and running the program manually.

I haven't used Linux Mint before, and when I have some time, I'll check if I can reproduce the issue. I'll update you if I find something.

Thanks for all your help, I look forward to hearing whether you find anything.

At the moment, it's a nice-to-have. If I have to manually run the program when I start the computer and then relegate it to a background task so I can close the terminal and continue on with my day, then so be it (it can remain a party trick for when I'm feeling particularly spicy).

Good evening everyone!

I hate to be that guy on the internet, but my problem seems to have resolved itself. For reasons unknown, after doing some system updates today, the damn thing turned on by itself, and is now automatically running on startup.

The only other thing I can possibly think of maybe having an impact on it was that I was trying to get Steam to recognise my other M.2 drives in the system (so I could choose where to install my games), and in the process I had to change access permissions on my drives from root to my user account. Maybe that was the trick?

Thanks :)

It is possible that you accidentally changed permissions on kernel files, making CPU resources or your USB device inaccessible. I'm glad you managed to fix it, so everything works as expected.
