https://bugzilla.kernel.org/show_bug.cgi?id=99041 --- Comment #1 from Florent Le Coz <louiz@xxxxxxxxx> --- The issue is still present on kernel 4.0.7. Little precision, that may be useful to diagnose the problem: - If I boot with that HDMI-connected screen turned off and then I turn it on with my X session already fully started, it is not automatically detected (the screen says “no signal”), but this used to work on older versions of linux (can’t remember which one introduced this “regression”). Next, if I manually configure it with that command: xrandr --output DVI-0 --mode 1920x1080 --output DVI-1 --right-of DVI-0 --mode 1920x1080 --output HDMI-0 --right-of DVI-1 --mode 1920x1080 the image on the screen works, but not the sound. - However, if I boot while that screen is already turned on (or if I turn it on while still on the gdm login screen), it is automatically detected and both the image AND the sound BOTH work immediately. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
