Re: Monitor control issues after update

Hello Vasile,

$ sudo ddcutil setvcp 60 0x1b Display not found

I'd look at the source of the ddcutil program to see what conditions can make it print ‘Display not found’ as that might give a clue as to what particular step is failing. There's also looks to be lots of documentation on ddcutil's site, e.g. https://www.ddcutil.com/config_steps/ suggests ‘ddcutil environment’ and ‘ddcutil usbenvironment’. There are other pages on that site worth looking at. -- Cheers, Ralph.
