Suggestion for README: reboot after changing i2c group permissions #74

Closed kirkpsmith closed 4 months ago

Hi, this worked great for me, thanks for this tool!

I have one suggestion that may make this clearer in the installation README, highlighted in bold below:

Finally, you need to install an udev rule to allow members of the group i2c to access i²c devices:

$ sudo cp /usr/share/ddcutil/data/45-ddcutil-i2c.rules /etc/udev/rules.d

Rebooting your computer may be necessary for these new permissions to take effect.

Now, you can verify that ddcutil is working correctly:

This may make installation more straightforward. I didn't realize I had to do this to get it to work.
