Bug 1226161

Thanks for reporting, please update and see if it launches now, I think I fixed it (I saw the same error and now it launches on my intel notebook).

If you watch Slimbookteam's github, it seems they are refactoring these amd and intel controller apps heavily currently. No idea when these changes will end up in new releases...

Unfortunately it still fails with:

Obviously you haven't read the manual, this app doesn't run without a config file in the expected place below your home directory.

I'm sorry - I didn't want to sound rude, and the manual I linked isn't very clear about needing this config file as a prerequisite to launching.
A basic file is provided below /usr/share/slimbookintelcontroller/src/configuration/ - copy this to ~/.config/slimbookintelcontroller, and try again.
Possibly you have to add your CPU to the config file as described in the manual.

Sorry,
I skipped that part because I assumed it's needed for non-slimbook devices only.
