I just had this same issue (except trying to go from 1400x1050 -> 2800x1050 dual screen), but just running amdcccle and restarting X fixed it for me. Could a note for this go in README.Debian, or have debconf display a notice on upgrades, or something?
And FWIW, this information appears to be stored in /etc/ati/amdpcsdb, in the [AMDPCSROOT/SYSTEM/DDX/RECENTMODE/SCREEN00] section for me (`Width', `Height', and `Refresh'), though I assume you're not meant to edit that directly. -- Andrew Deason adeas...@uiuc.edu -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
