'FN -> Super' not working (MSI Modern A11SB)

[msigurd]

Application works great. It has most features available in MSI Center Pro on Windows 10/11, except for FN -> Super which is currently greyed out and not working in MControlCenter. I've reported this in tested_devices.md.

Providing current configuration and EC dumps for additional info.

Can you check on the application in the mcontrolcenter.tar.gz archive?

[msigurd]

That made it work perfectly. Great job!

[msigurd]

Reopening as I realized you might want to have this issue opened till you've merged with main. Sorry about that!

[msigurd]

So FN -> Super works now all of a sudden, on the current MControlCenter release (0.3.0) without using the fix that you provided above.

Not sure what fixed it, as I both received a Linux kernel update (6.0.3), and had the EC reset after my laptop's battery depleted, earlier today. So not sure whether it was the update of the kernel or the reset of the EC that did the trick.

Might also note that mcontrolcenter.desktop now finally shows the MControlCenter icon, instead of just the placeholder cog, in the application menu. This happened simultaneously with the FN -> Super starting to work.

Don't know if it's useful but here's another EC dump:

[dmitry-s93]

In the previous dump, you had a non-standard parameter value. In the current dump, the value is standard, so the function works without using the fix.

[msigurd]

Oh, alright. Guess a simple EC reset might do the trick for anyone else having problems, then.

[dmitry-s93]

Might also note that mcontrolcenter.desktop now finally shows the MControlCenter icon, instead of just the placeholder cog, in the application menu. This happened simultaneously with the FN -> Super starting to work.

Most likely, when updating the system, the icon cache was updated and the application icon began to be displayed
