OK, it is working now. I previously forgot to manually install the gcc4.9 dependencies.
Just to summarize in case someone went through the same struggle:
1 - Installed Ubuntu 15.10
-> Instead of being prompted for my disk encryption password I get a black screen! The screen actually goes of! This is related to my "AMD Radeon HD 7850"...
-> Luckily it is possible to enter the password in the "dark" - Workaround: add "GRUB_GFXPAYLOAD_LINUX=auto" to grub.
2 - Obviously, if you buy this graphic card you kind of plan to use it, so I installed fglrx (updates and no updates)
-> system no longer boots, and it is not possible to enter the disk encryption at all.
-> To address the disk encryption issue had to remove "splash" from grub configuration, leaving it like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet", the previous (1) grub hack no longer works can be removed...
-> the driver itself does no work, had to remove it after booting in single mode.
3. Installed the packages proposed on the previous post (updates)
-> Together with the previous (2) grub hack everything is working again. I mean, not as good looking as it should but, it is working.
This was the reason I left Fedora 4/5 years ago!!!
