If my laptop boots with blue network logo, no networks detected, networking disabled (still connected to the internet, weird no?) Then my sound is also not working, the soundcard just displays a “Dummy” output. I have also noticed mounting/unmounting USB drive requires root permission window, instead of automatically handling, (it is possible suspend also requires root permission window.)
All this with the blue logo, one in three boots. All I can say; is Tumblweed unstable?
I found out just yesterday that plymouth can cause that your user session is not correctly registered with the seat.
As a consequence you don’t have permissions to mount/unmount drives, there’s no sound and so on.
Uninstalling or disabling plymouth fixes that.
Just try it. If it doesn’t help you can install it again.
Btw, the bug report is there: https://bugzilla.novell.com/show_bug.cgi?id=816942
Maybe you could post a comment there? (same login as here in the forums)
Because until now this is only confirmed for 12.3 when booting to runlevel 3 and starting KDM via “init 5”…
