I'm using tigerVNC and I'm quite satisfied with it but I can't seem to be able to change the quality level. Appending arguments behind $vncviewer like QualityLevel=4 doesn't help, because it is choosing it automatically based on your bandwidth
CConn: Throughput 1275 kbit/s - changing to quality 6
And quality 6 is way too much. More over I don't have 1275 kb/s but 1024 kb/s.
It renders incredibly slow. Can't use it like this.
So the parameter that turns this feature off is
-AutoSelect=0
Manual says that
but it also affects QualityLevel among others
