I have installed the closed source nvidia driver(nvidia-driver-440), and > I am able to successfully get every display on every single boot. Cool-so we at least should be able to trace the nvidia blob to figure out what's going on. Do you think you could grab an mmiotrace of the nvidia blob with all of your displays hooked up? https://wiki.ubuntu.com/X/MMIOTracing You might also need to add: iomem=relaxed To get that working. fwiw as well, that guide says somewhere to stop X afterwards before stopping the trace. That may or may not work, and it should be fine if you just leave X running when stopping the trace instead. For submitting the mmiotrace to me, it's probably going to be somewhat large so I would recommend compressing it with xz and just sending it directly to my email. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
