Seems like everytime there is a major kernel update, my monitor stops working, or rather I can’t boot because it shuts off. this is a new 32 in curved monitor connected with display port 1.4 cable.
I can’t use a different kernel that I currently have because the LTS kernels always give me a blinking cursor and don’t boot. my current fall back kernel gives a bunch of fail messages and doesn’t boot either.
My rig is a desktop with AMD Vega 64 GPU. I’m pretty sure I have the amdgpu driver, but, it happens with both it and the ati driver. I don’t have a HDMI cable to test if I can access the system connected with HDMI, but, I imagine so. I use dp because it is a new gaming monitor with freesync and you must use dp 1.4 for freesync to work.
I need to find a way to downgrade my kernel to the last one from a live USB and a fix for the display port problem for future kernel updates.
