Yesterday I installed Ubuntu 14. 04 on my notebook and had many troubles with it.
- Installed Ubuntu 14. 04 configured everything how I like it (minimal changes) and then enabled in additional drivers new Graphic drivers ("Nvidia binary driver -version 331. 38" (propretiary, tested)). The result was that Ubuntu has been damaged and I could not boot etc. No solution of solving this problem I found on the forums worked for me.
- I used my previous Clonezilla Image and reinstalled Ubuntu 14. 04. With the opensource drivers everything ok (but it does not run as smooth as it does with the Nvidia drivers).
My notebook was running while I was not near it. When I came back my Notebook was in sleep mode. After I pressed the Power Button it tells me that I am offline (Wi-Fi). When I try to reconnect it shows really all Wi-Fi Routers near me, but not my personal Wi-Fi Router Access. Under "more networks" I can't find it too. When I go to Dash and search for Network there is a huge list of available Networks, but not my own. When I switch to an other OS with the same Notebook I can find my Wi-Fi SSID. And I am sure that it will work again when I reinstall Ubuntu again. But this would be the third time and I don't want to reconfigure all again.
So is there a solution for this problem?
