lubuntu-qt

[farinet at arcor.de]

First of all: Is this the right place to ask about LXDE-qt and lubuntu-qt?

If not, please point me to the right place.

Anyway, here comes my first problem:

I installed lubuntu-qt/LXQT (and installed the ppa as well). Now, from
the lightdm login i can choose LXQT or lubuntu-qt.

LXQT starts. lubuntu-qt tries to start but the turns back to the login.
One problem both have in common is, they tell me they cannot set the
<Fn><F6> thru <Fn><F8> (= audio off, lower, raise). In LXQT i see the
volume icon (mixer) is dead. May be there's missing a qt native mixer?

And: Could the missing mixer be the reason why lubuntu-qt refuses to start?

TIA!
