Hello, misc; I've been having an issue with my OpenBSD install, specifically when the system turns off the monitor after a period of no use. After the monitor goes blank I can't use the start using the machine and must restart, that is after keypress and mouse movement the system does not show anything on the monitor. I suspect something is wrong due to hardware. I've checked the logs, nothing seems to be off. I've turned off apmd as to not interfer with power management and still no response after the monitor goes to sleep. Here's a list of the hardware: - AMD Ryzen 5 3400G Processor - Asus Prime B550M-A/CSM Motherboard - Radeon RX 580 POLARIS10 GPU Has anyone else experience any issues with like this? Is there still no support for polaris GPUs? Thank you in advance. Ben Raskin
I've had this issue as well with a Ryzen machine with an R9290x graphics card (ie not supported by AMDGPU). My monitor is using DisplayPort but the same behaviour is present when using HDMI monitors as well.
I've found the only way I can get output to the screen again is by switching consoles with CTRL+ALT+F1 and then switching back to the xorg console with CTRL+ALT+F5.
Not sure what the cause is, but I've always assumed it was an issue the the radeon driver.
