Nevertheless, I can't get the X modesetting driver working on my Optimus hardware (HP ZBook 15 G2, hybrid graphics Intel/NVidea), whatever setting I choose in BIOS for Hybrid Graphics (Enabled/Disabled/Auto). Maybe this is beyond the scope of this mailing list, but it might be also important to decide how and when to replace nouveau/nv by this built-in modesetting driver.
I don't think there is yet enough predictability as to which hardware works better with the built-in modesetting driver.
Even if I uninstall xf86-video-nouveau and xf86-video-nv and call mkinitrd the module gets into trouble:
[ 13.343] (II) modesetting: Driver for Modesetting Kernel Drivers: kms ... [ 13.361] (WW) Falling back to old probe method for modesetting [ 13.361] (EE) open /dev/dri/card0: No such file or directory ... [ 13.363] (II) UnloadModule: "modesetting"
I had no /etc/X11/xorg.conf and no extra kernel parameters at all, just to make sure. Did I miss something?
Maybe a key difference between OP's gfx and yours?

Just forgot to mention: I got it working just when disabling Hybrid Graphics in BIOS, but just along with the intel video driver. But I want to activate the NVidia device.
I saw no evidence that the OP was using hybrid gfx. AFAIK, fully functional hybrid video demands special video drivers, Optimus, Bumblebee, Prime, or maybe something else???
Interesting here (on this HP ZBook 15 G2 - Optimus hardware) is the fact that if I set the BIOS option Hybrid Graphics to Enabled, KMail 5 doesn't crash and I don't have to launch it by prepending "LIBGL_ALWAYS_SOFTWARE=1 kmail". But the second display doesn't some sometimes appear (unpredictable). On the other hand, if setting Hybrid Graphics to Auto, Kmail 5 starts to crash in the way described in https://bugs.kde.org/show_bug.cgi?id=369514, but the second display does appear reliably. Disabling Hybrid Graphics means there's just the on-board Intel graphics available, but not NVidia. The NVidia card is a NVIDIA Quadro K610M with 1 GB. In a separate discussion in the Bumblebee project they found out after several tests, that Bumblebee does work for my hardware just if booting from EFI, but not the legacy BIOS like me. See https://github.com/Bumblebee-Project/bbswitch/issues/118. I'll retry migrating to UEFI as soon as I can, maybe this will improve the situation. Otherwise doesn't probably make sense to use any Optimus switcher, because the ACPI table contents are wrong. Anyway, most reliable is still the NVidia proprietary driver (370.28), although there are rendering issues in Plasma desktop and it doesn't use Optimus technology, though. And recompiling after each second update is uncomfortable. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
