I'm using Ubuntu 14.04 LTS on my laptop. I installed the drivers for my graphics card from AMD Support (first download). Then I restarted my laptop. Now I have a black screen before the graphical login screen with the user selection. GRUB works fine; I can see its advanced options. This screen happens after the disc has been decrypted.
What's happening? How can I fix it?

This sounds alot like a problem I had recently, as detailed at https://unix.stackexchange.com/questions/241577/grub-menu-not-visible .
The short version is:
sudoedit /etc/default/grub
, find the line that says#GRUB_GFXMODE=640x480
and uncomment it (delete the#
), and save your changes.sudo update-grub
(This step is important. I missed it the first couple times and accomplished absolutely nothing.)If that works, you will see the grub menu on your next startup. Assuming it does work, follow the linked instructions to determine the screen resolutions your system supports and step up through them until things stop working, then back up one step.
Hope that helps.
