Upgraded from 15.04 to 15.10 but on reboot my video is not coming up. I am using a AMD Radeon HD 8200/R3 series.

The AMD Catalyst driver is having issues to work with kernel 4.2.

Reference : A Fix For AMD Catalyst On Ubuntu 15.10 Is Coming.

As a workaround uninstall the AMD proprietary drivers meanwhile. 

sudo apt-get purge fglrx

There is a workaround fix in wily-proposed but it is recommended to wait until it is tested.

Use the open source radeon drivers in the meantime until the final Catalyst fix is released.

Note :

In case you are experiencing problems to do this from the desktop you can use a virtual console.

From login screen press Ctrl + Alt + F1 - enter user name and password - execute the command.

  • Might be a good idea to also include the steps on doing this from a tty1 (i would assume problems with "video" means not getting a desktop ;) ) – Rinzwind Oct 28 '15 at 15:30
