I have a Samsung laptop with a Radeon graphics chip.
Live-Images and graphical installation have always worked on this laptop with the proper resolution of 1366x768. However, after Ubuntu had been installed, I ran into the black screen problem which so far, I solved by setting nomodeset temporarily during the first boot which gave me a resolution of 1024x768. Having booted like that, I would then install the fglrx driver, reboot and enjoy my Ubuntu with the proper resolution.
Since I can't use the fglrx driver in Ubuntu 16.04 I am stuck with either a black screen (without using nomodeset) or a distorted display due to the wrong resolution of 1024x768. I tried setting the resolution manually with xrandr but I think since I have to use nomodeset there's no way that I can do that.
Is there any way to fix this? I know that I could stick with Ubuntu 15.10 but I would really prefer an LTS version.
amdgpu
driver?sudo apt-get install xserver-xorg-video-amdgpu libdrm-amdgpu1
. Both packages were already installed...
