I have Ubuntu Studio 14.04, it is the only operating system on my machine. Every time I boot up, the BIOS loads, and then the screen goes dead and will stay that way unless I press ESC, in which case the prompt to enter my password for disk encryption appears, after which everything proceeds normally. It's always done this since I installed it a few months ago. But when I realized I only had to press ESC, I decided to ignore this (minor) matter. But sometimes the screen stays dead after waking it up from being suspended, and then nothing I do with the keyboard helps - which maybe is a separate question, or maybe is related.
What is this about and how can i address it?
Update: I installed a proprietary driver from Nvidia, based on Azendale's input that the graphics driver may be the issue. The problem has now been replaced by a different problem. My USB keyboard doesn't work until after the password for the disk encryption program is entered, so I keep a standard keyboard connected just to enter it. It still seems, as Zacharee1 mentioned in the comments, that the disk encryption software is the cause of both issues, and I need to remove it.
In case it wasn't clear and it in some way matters, only the ESC key would get the screen working before.
