I don't know what happened, until yesterday my notebook was working great, today I turned it on, did not connect to WiFi, after rebooting even the tray icon disapeared. I try to get into some configuations like Time & Date no permision, Network no permision, Network Connection I can access it but I can't do anyting, everything is grayed.
Under Session & Starup Network is listed to autostart
It looks like my user lost some rights and isn´t running some services. I don't remeber changing anything of this, I just downloaded some movies from youtube last night and played cards
<strike>I tried to log in as su from the GUI but looks not to be possible, from a terminal is it possible but I'm not skilled at all with all linux commands</strike>
Shame my self, I've used the wrong user su instead of root
I logged as root and found my network is disabled, when I enable it a message appearsThe configuration could not be saved Invalid data was found
for the wired config I just choosed DHCP
I'm using xfce
If someone could give some tips how to recover it I would appreciate any suggestion and guidelines
