Re: Logging in/out on console while logged in in X removes hardware acceleration

Thanks for the reply. In the first place, I was wondering if creation of /dev/drm1 (same major and minor) is even possible. In Linux I can create as many devices I need pointing to the same major & minor numbers (for example creating a /dev/null for a chroot jail). If the logic is the

| Well then, I guess I just stop switching around between different login sessions What about avoiding Ctrl+Alt+F1 (and ... F5 wich is X) and use ... +F2, +F3, etc.? You could still miss some settings, I am not sure. I wonder if /etc/fbtab is able to support multiple tty entries and manage them

Logging in/out on console while logged in in X removes hardware acceleration

Dear all, logging in and out changes the owner of the /dev/drm0 file, so that one loses hardware acceleration in X when additionally logging in and out on a console. Here's what I do: 1) Boot Openbsd and log into X with xenodm. Ownership of /dev/drm0: $ ls -l /dev/drm0 crw---
