Xorg.0.log including the segfoult
History (maybe only partly related to the problem):
I followed this guide to update my drivers:
<a href="https://github.com/ValveSoftware/Proton/blob/proton_3.7/PREREQS.md">https://github.com/ValveSoftware/Proton/blob/proton_3.7/PREREQS.md</a>
sudo add-apt-repository ppa:paulo-miguel-dias/mesa
sudo apt dist-upgrade
sudo apt install mesa-vulkan-drivers mesa-vulkan-drivers:i386
which worked fine for some days. I updated my system as normal (via apt) and
after a reboot the machine came up with a black screen.
I found a segfault in my Xorg.0.log (attached). Blacklisting the module
"amdgpu" lets me boot into the desktop using only the integrated Intel GPU.
Some information that are hopefully helpful:
$ lspci -k

$ uname -a

2018 x86_64 x86_64 x86_64 GNU/Linux
My PC is a notebook with an integrated Intel GPU and a dedicated AMD GPU.
OS is Linux Mint 19 Cinnamon
CPU is Intel© Core™ i7-7500U CPU @ 2.70GHz × 2
What else is needed?
Can I somehow re-install or downgrade the amdgpu-drivers?</pre>
