Im new to Linux and therefore also Lutris, I have installed it and synced Steam but when i try to log in to GoG or Epic I just get a blank screen and when I run Lutris in terminal and try to log in to either off them i get this over and over “AcceleratedSurfaceDMABuf was unable to construct a complete framebuffer”
What can I do to fix it? 
Hi,
Please make sure you include your debug - the version of Lutris etc.
That said, interesting bug - looks like an issue outside of Lutris - a quick search shows a few people with NVIDIA cards have a similar message. You’ll want to do the same search for that specific error.
From what I’ve read, some people worked around it by adding the line WEBKIT_DISABLE_DMABUF_RENDERER=1
as a system-wide variable in the file /etc/environment (you’d need to use sudo to edit that file) then restart.
Once the package (or NVIDIA driver) is fixed, you’ll be able to remove it.
