Hello, I recently installed OpenBSD 6.5 on an i386 router. The intallation process went fine. However, I got a black screen after rebooting.
I tried opening a SSH session, but the computer doesn't reply. The screen is attached using a VGA cable. The computer send a signal over that cable. If I detach it from the router, the screen turns off. If I plug it back, the screen turns on (but nothing is displayed). I send you the dmesg output. I took pictures of the output and used an OCR to convert them to text format. Thank you !
