Thanks for posting this summary!
(I'm experiencing some of these, and misery loves company :-) )
*Lots* of balls in the air: Xen, Qubes, Fedora, KDE..... Hard to know
which causes what, but ISTM bare-metal Fedora/KDE users are experiencing
many; so like others, I try to visit Google and Fedora/KDE user groups
first before mentioning issues here. (e.g. Sleep is one for me - and
apparently for the bare-metal Fedora/KDE community as well.)
So it is nice to see a summary such as yours - not to complain to Joanna
and Merak - but to share a big Xen/Qubes/Fedora/KDE picture.
