[ddccontrol-users] Missing monitor: ACR0050

[Mikko V. <t8m...@ca...>]

Hi! Thanks for this lovely tool. I ran it and it asked me to email you. However, the required command (LANG= LC_ALL= ddccontrol -p -c -d) would not complete but instead keep printing

Non-fatal error: Invalid response, magic is 0x6e
Invalid response, length is 110, should be 8 at most

over and over again. Instead, here's the output of

LANG= LC_ALL= sudo ddccontrol dev:/dev/i2c-1 -c -d

in case this is of any use. I can do other printouts if not, just ask. (I could change brightness just fine. This is an acer x223w just it case it's not obvious)
