Sorry: I mixed up the mailing lists... the bug I pointed out is with the radeonHD driver. Tip: I alway keep a terminal open and in focus, so that I can type "xrandr --auto" (or s.t. appropriate), in case the screen goes black. If you wish to use a GUI to switch resolutions, you can also have a terminal in the background running, and execute there: # sleep 30 && xrandr -q && xrandr --auto And then switch your resolution. That way you'll get a print of what happend, and then resolution returns to something working. Anyway, good luck :) Daniel -- PGP key @ http://pgpkeys.pca.dfn.de/pks/lookup?search=0xBB9D4887&op=get # gpg --recv-keys --keyserver hkp://subkeys.pgp.net 0xBB9D4887
