Comment 16 for bug 148208

The commande "xrandr --output default --mode 1680x1050" doesn't change anything.

With the initial settings, after reinstallation of kubuntu, I check Monitor & Display>Display Format. It was set to 4:3. I change to 16:9 without effect.

I remember that with Opensuse, the problem was solved with a graphical tool which permit to slighty modify the monitor frequency. Do you know such a tool on command line?
