Hello!
I’ve recently needed to reinstall my installation of bazzite.
Ever since this reinstallation I’ve had problems using my displaylink dock, fullscreen games will display a black image whilst focused. It spits out the following error:
Jan 22 16:44:34 laptop kernel: evdi: [E] evdi_painter_grabpix_ioctl:1090 Failed to map scanout buffer
I have enabled the drivers through the ujust enable-displaylink command.
Any help wound be appreciated
Just to get an idea of what you’re doing here, are you trying to have both the internal laptop GPU and an external desktop GPU active at the same time, by way of the displaylink dock?
The displaylink dock is connected to the usb-c port with displayport support, which I believe is internally connected directly to the dGPU. I run it in hybrid mode, so both the iGPU and dGPU are active. To the dock are two external displays connected.
Odd, 'cuz it worked fine before the reinstall. Switching my laptop over to just dGPU does fix the problem. I guess it has something to do with PRIME/Optimus? I launch the games with the following env variables: __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only
