Black screen with X cursor after upgrade from Yakkety

[kayvee]

Just upgraded my Yakkety installation to Zesty. Download and installation went well and was prompted to reboot the machine. After reboot, I end up with a black screen and an X shaped cursor. I am wondering that this could be due to the presence of nVidia graphics card using proprietary drivers. Is there a way for the use of nouveau drivers instead? I need to do this from the command line.

There could be several possibilities. One is that ~/.Xauthority had an ownership change to root. You can check that from a CLI.

Another could be that Zesty's kernel doesn't support the dkms NVidia needs. Oshunluver & VINNY found this out. Try oooting using the previous kernel (in the recovery section of the Grub menu).

is this a clean install or did you do a net upgrade ?

eather way try this ,,,, https://askubuntu.com/questions/3878...stalled-ubuntu ,,,,,, to boot with the nomodeset option

and see if you can get booted in .

Thank you all for your responses. I think acheron is correct. There was some kind of issue with nvidia modules. I don't exactly remember how I came around to seeing that error message (I was fiddling around to get the display server use nouveau drivers instead of nVidia drivers) but that's what made me completely purge my system of nVidia drivers. Then I was able to login fine using nouveau drivers. Once I had the graphics up and running, I decided to reinstall nVidia drivers just to see if it works and it did. In hindsight, looking at the links acheron has posted, it all makes sense.
