Hi Michele,
since I want to keep my older version installation intact, I installed on another disk drive the stock Debian 12 with the previous version of TDE 14.0.13. On this clean installation, I tried Fn+F1 (XF86Sleep) and the function worked perfectly - the laptop went to sleep. The same for XF86MonBrightnessUp/Down.
I then upgraded to the latest version of TDE 14.1.0 and rebooted just to be sure. From now on XF86Sleep nor XF86MonBrightnessUp/Down initiation does not work. The only thing that has changed on this setup is the TDE upgrade from 14.0.13 to 14.1.0.
In conclusion - I assume that this test shows that the problem must be somewhere on the TDE side. Maybe the binding of some XF86* events is disconnected? Hard to say for me ...
Cheers -- Petr Palacky

I don't have any special ACPI programs or utilities for the older installation, and it's practically a standard installation of Debian 9 + TDE 14.0. In the case of a newer Debian 12 + TDE 14.1 installation, this is also a fairly standard installation. I checked the installed modules (older versus new installation) and they are pretty much the same everywhere.
Hi Petr, I don't know if it is something easily feasible for you, but a good test to determine whether it is a kernel issue or a TDE issue would be to update the old installation to R14.1.0 but keeping the existing 4.9 kernel. If the problem shows up on R14.1.0 with the old kernel, it is definitely something in TDE. If R14.1.0 works fine, it is more likely not a TDE issue. Alternatively (or as additional test), running R14.0.13 on the new Debian 12 would also help providing further info.
I don't have a Dell with TDE, but usually brightness and volume controls work fine, so I would be surprised if they didn't on a Dell. Until 7 years ago I had a Dell and they were definitely working back then (I was running R14.1.0-dev) although it was long ago.
Cheers Michele
