https://bugzilla.kernel.org/show_bug.cgi?id=121481 Bug ID: 121481 Summary: No video output after loading nouveau module Product: Drivers Version: 2.5 Kernel Version: 4.7-rc6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: demfloro@xxxxxxxxxxx Regression: No Created attachment 222091 --> https://bugzilla.kernel.org/attachment.cgi?id=222091&action=edit dmesg for just modprobe nouveau OS: Arch Linux Video adapter: GeForce GTX 780 Ti Since 4.7 loading nouveau module results in black screen, but when I load nouveau module with parameter debug=trace the issue does not appear, screen successfully switches to correct resolution and Xorg can be successfully started. I did following: - after OS booting I issued command "modprobe nouveau", in this case execution of the command took about 44 seconds; - when "modprobe nouveau" returned control to shell I blindly issued command "startx" on terminal in VT; - after that machine was rebooted with "reboot" - after reboot I issued command "modprobe nouveau debug=trace", it took about 11 seconds to finish; - after that I issued "startx" and Xorg started sucessfully. If I compile nouveau module in kernel then I lose video output right after kernel loads if I don't pass nouveau.debug=trace parameter. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
