Linux Mint 19.3 Tricia (Ubuntu 18.04), GForce RTX 2080 TI OC 11G with two Iiyama 30" Monitors via Displayport.
I’ve got a strange issue since last evening. Did some updates, Kernel 4.15.0-1nvidia-bug-report.log.gz.txt (798.7 KB) 22 generic (because the 2080 has strange issues with Kernel 5.x).
After reboot, both monitors went dark when starting the nvidia driver. After a while I found out: removing one of the two DP cables gives the image back on one monitor.
Updated the NVIDA driver to 455, reverted to kernels up to 4 versions before - nothing changed.
Could this be a hardware problem? It worked flawlessly since September 2019 .
