I have caffeine installed, and it works just fine in gnome-classic (no effects) for preventing sleeping for most processes. For example "vlc", "mplayer", and "totem" all work. I cannot get it to recognize quodlibet. It used to work in Lucid, but after a recent upgrade, it doesn't work.
I have tried
qoudlibet
and
python /usr/bin/quodlibet
and
/usr/bin/quodlibet
as the process name, and none of them work. Any ideas?
