I had such a problem and solved it by installing firmware for the
graphics card.
From lspci:
VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri [Radeon R5 Graphics]
I *had* to install some sort of working Firmware before I could even get X to work. (I was limited to oversized Text Screens of 80x24, like the old IBM Monitors from my IBM Mainframe days!)
Installed Firmware: "firmware-linux-free", "firmware-linux-nonfree", "firmware-misc-nonfree", "firmware-amd-graphics", and "firmware-realtek".
Thank you.
