The issue is that shadow_fetch() fails for ACPI. It tries to read a 0xf800-sized image and apparently can't. Both the fast and slow methods end up the same. Also it's NPDE is set to "HYB$", although looking at the code that shouldn't really matter. However something's there, since it gets far enough to e.g. check the NPDE. Either the _ROM method is buggy, or we're driving it slightly incorrectly. -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.

Created attachment 134558 [details] dmesg with nouveau.debug=trace + acpidump + xorg.conf I've got a portable computer with an Intel graphic card and a nvidia discrete card (G 105M). I've installed Fedora 26. Everything should run fine with nouveau and Prime. However, xrandr --listproviders only send me 1 provider, which is the Intel card. I've seen a problem with the BIOS and the nvidia card : [ 2.777871] nouveau 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0x0000 [ 2.777887] nouveau 0000:01:00.0: bios: unable to locate usable image [ 2.777895] nouveau 0000:01:00.0: bios ctor failed, -22 ----------- $ lspci |grep -E "3D|VGA" 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) 01:00.0 VGA compatible controller: NVIDIA Corporation GT218M [GeForce G 105M] (rev a2) $ xrandr --listproviders Providers: number : 1 Provider 0: id: 0x46 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 4 associated providers: 0 name:Intel
