After upgrading to 535.43.02 ddcutil (ver 1.4.1) can’t find any display. It used to work in 530.41.03. Setting options
NVreg_RegistryDwords=RMUseSwI2c=0x01;RMI2cSpeed=100 doesn’t help.
fixed in 535.54.03. Thanks!
I just upgraded to 535.43.03 and DDC/CI stopped working for one of my monitors, both are DP connected. This is with OpenSUSE Tumbleweed with kernel 6.3.7-1-default. I have always used the RegistryDwords settings - and I’ve confirmed they’re still set:
grep RegistryDwords /proc/driver/nvidia/params
RegistryDwords: "RMUseSwI2c=0x01;RMI2cSpeed=100"
The monitor that is no longer recognised is a old HP ZR24w which was detected fine with 525.116 and earlier. I’m using ddcutil as my DDC/CI tool.
