Created attachment 595690 [details] Xorg log file When I install media-libs/mesa-19.2 or higher on my system, X will fail to start up. When I start X with media-libs/mesa-19.2 installed on the system, all connected monitors will go blank and stay blank, except for a small white line in the upper left corner. (Looks like the text input cursor in text mode, except it's not blinking.) Pressing NumLock, ScrollLock or CapsLock on the keyboard will not toggle the respective LED lights on the keyboards. The system is still pingable over the network, and I can still log into the system using ssh. The same thing happens with version 19.3.0_rc2. With media-libs/mesa-19.1.7 installed, these problems do not happen, and X starts up normally. The system has one graphics card with an AMD "Navi" chip (Sapphire Radeon RX 5700 XT Pulse), with three monitors attached, all of them connected via DisplayPort. sys-kernel/linux-firmware is at version 20191022.

The problem went away for me (at least for mesa 19.2) after upgrading LLVM to version 9 and recompiling mesa.
