When gnome 3 first appeared in sid, I noticed that plugging in my external monitor to the laptop didn't work automagically, as it had done in gnome 2. In particular, I remember wrong resolution and/or fuzziness/shakiness like you report. What worked for me then was to fix my setup in a few steps instead of one step. What I mean is that I chose a worse resolution first, and confirmed that change when asked. Then as a second step I chose the desired setup and confirmed that. I don't have the external monitor now so I can't test this again for you, but something like this worked for me. Play around with various settings, and confirm them even if they don't work well. You can also try disabling and re-enabling the laptop screen, maybe with different resolutions. (I was actually using only the external screen most of the time.) Eventually you can go back to what you really want and hopefully have it work properly. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
