While Wayland is installed here, I don't actively use it. I'm sure it is running since things are switching in that direction tho. I just still use the old X stuff as far as what I select when logging in. Unless it changed without me knowing it. > >>> You can automate the rotation of this file with logrotate.

I'll do that if the file shows up again and starts getting some size. I have no idea how logrotate is setup nowadays. I haven't messed with it in ages. I do logout and back in once a week tho. Whenever the updates are done. Dale :-) :-)
