I updated tumbleweed, and when I access to kde (also secure mode), my screen result mirrored and turned over, a very strange behaviour, what the heck happened, how can I solve??
if I access in lxde it’s ok.

ciao, pier 
What do you mean “updated tumbleweed”, there is no Tumbleweed yet, only some git packages.
Pier,
Question: NVIDIA card? Did your update include the xorg-x11-server package? If so, reinstall the NVIDIA driver packages, reboot and see if this phenomenon has changed.
Another question: does the issue exist for a newly created user?
I intend update the packages (the blue ones in yast add remove software window) of tumbleweed repos :-))
yes, nvidia card, about xorg-x11-server I don’t know, I updated all the list, I reinstalled the NVIDIA driver packages in the hard way that isn’t hard, first with the last version, the 304, and it failed I think becouse an error about the different version of the gcc compiler of the kernel and the driver module (4.6 for the driver and 4.7 for the kernel, or reverse I don’t remember well), so I reinstalled the 295 version, now it works, thank you :-))
I don’t know, I didn’t tried, and now works so I cannot try :-))
