It looks like you might be affected by this Debian bug: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=578587
Regarding the wireless problem, is your network device firmware configured properly? One way to tell is to run "ifconfig -a" and make sure a wlan0 entry shows up.
Yes, the interface is visible in 'ifconfig -a'. I have Intel card that never caused any problems under Linux. I tried starting gnome-keyring-daemon manually. The only imporvement I got was asking me for a password to securely store my wifi password but it wasn't saved anyway.
Other than that, I have noticed that nm-applet is not exactly user-friendly; if one little field is not configured correctly it won't enable the "Connect" or "Save" buttons, and it won't tell you what you did wrong either.
I think I got all the fileds right. I'm getting a bit frustrated about NM. It caused me a lot of problems in the past and it's causing them once again. In fact these error seems to be exactly the same as the one I was getting on suse 12.2 and KDE3. Looks as though nm-applet had no permissions to manage connections.
Did anyone have similar problems with gtk-qt packages I mentioned earlier? Right now GTK appications look horrible, I'd like to get integration working. Surprisingly I see files .gtkrc-2.0-kde4 and .gtkrc-2.0-kde-kde4 in my ~, though I didn't use KDE4.
And a few other things: - can I disbale the "Press Ctrl+Alt+Del" dialog in KDM? - is there a package that provides DMZ cursor theme for X? - can I decrease the size of panel applet responsible for switching between desktops? In KDE3 when I select "elegant" as a background option the applet becomes small so that each desktop is represented by a square icon, while in Trinity this applet is actually quite wide. I don't know if it's clear what I want to achieve. If no then I'll provide a screenshot.
