Routing display through another drm card
idk-some-guy opened this issue · comments
Hi, First of all, let me describe my setup:
my main adapter is drm card1, but my display output is routed through TB into card0-DP-3
If i run gamescope -- glxgears from TTY, everything works as expected. However when gamescope session tries to launch, if I specify -O DP-3, it will appear to work, however it will choose card0 as the vulkan device to render according to logs, and as that is not a real card in my system (i do not have an iGPU), only a display route, nothing will actually get displayed. If I add --prefer-vk-device [card1-id], the logs say that it correctly picked the card, but does not find any connected port. would it be possible to specify card1 as renderer and card0-DP-3 as output connector, so it would work similiarly to running gamescope in TTY?
