Description Dominik 'Rathann' Mierzejewski 2018-12-31 00:03:29 UTC
Created attachment 142919 [details] Xorg.log with intel+nouveau drivers I'm getting black output on HDMI-connected display driven by nVidia GeForce GT 525M (GF108M). Mouse cursor is visible on both built-in display and on the external HDMI-connected display. This used to work on Fedora 27. I can see this on Fedora 29, but I can't pinpoint which package update broke it because I haven't checked the external display (a projector) for quite some time. This machine is a Dell XPS 15 L502X with Intel HD3000 integrated graphics and nVidia GeForce GT 525M discrete GPU in Optimus configuration. Here's my xorg.conf snippet: Section "Monitor" Identifier "Internal LCD" DisplaySize 345 195 EndSection Section "Monitor" VendorName "Benq" ModelName "W1100" Identifier "Projector" DisplaySize 16900 9400 EndSection Section "Device" Identifier "Internal Graphics" Driver "intel" Option "Monitor-LVDS1" "Internal LCD" Option "TearFree" "on" EndSection Section "Device" Identifier "Optimus Graphics" Driver "nouveau" Option "Monitor-HDMI-1-2" "Projector" EndSection Switching both drivers to "modesetting" makes the issue go away. I'm attaching Xorg logs for both configurations.

Do you still get the problem if you use intel as the main driver and modesetting as the "GPU" driver?

Created attachment 142925 [details] Xorg.log with intel+modesetting drivers Yes, the same thing happens with intel driver for the integrated GPU and modesetting for the nVidia GPU. Xorg.0.log attached.
