I’m running ArchLinux, with the following package versions: linux 3.17.6 mesa 10.4.1 xf86-video-nouveau 1.0.11 Please tell me if I can do anything helping you to fix this bug.
You haven't really described the issue beyond "not working". http://nouveau.freedesktop.org/wiki/Optimus/ Where in those instructions do you run into trouble? I would advise against bumblebee -- nouveau will automatically put the card to sleep if it's not being used, and bumblebee will only interfere with that.
Created attachment 111620 [details] Xorg.8.log Well, in Bumblebee, this result in the attached Xorg.8.log, this is when trying to run glxinfo through optirun, and glxinfo works, but the output states this is not nouveau, but Gallium using LLVM pipe. With bumblebee and bbswitch disabled, and after clean reboot, the result of modprobing nouveau is naturally still the same, and I can’t use DRI_PRIME since: xrandr --listproviders Providers: number : 1 Provider 0: id: 0x49 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel

I had assumed you had one of the new-fangled optimus situations where the screens are attached to the igpu and 3d offloading can be done to the secondary gpu -- is that not the case? Using an xorg.conf with Device entries tends to mess all of that up, btw. (b) That error should have caused some nasties to be printed to dmesg.

That is supposed to be the behavior of Bumblebee (two X.org server, one with the integrated card only, another with the dedicated one only, fired up at demand, i.e. when you do optirun something), unless I misunderstood something somewhere. > I had assumed you had one of the new-fangled optimus situations where the > screens are attached to the igpu and 3d offloading can be done to the > secondary gpu -- is that not the case?

About xorg.conf files, I have /etc/bumblebee/xorg.conf.nouveau, which is used by Bumblebee and is attached, but I’ve also just seen that I have this in /etc/X11/xorg.conf.d/20-intel.conf: Section "ServerLayout" Identifier "Layout0" Option "AutoAddGPU" "false" EndSection I’m going to comment that section and restart X to see if it changes anything about DRI_PRIME. > (b) That error should have caused some nasties to be printed to dmesg.

X has to start after nouveau loads, otherwise it doesn't know about the nouveau adapter. (This may no longer be the case with DRI3-based offloading actually...)

Then, is there a way to force nouveau to load at boot, and else, is restarting X after loading nouveau supposed to work (for the record, tried that, and it doesn’t work either, but I’m not sure if it is supposed to work since it looks like I’m indeed affected by the issue you’ve linked).

You would still be able to use reverse-prime though, I think. (i.e. use the intel gpu to render to screens attached to the nvidia gpu -- sometimes HDMI/etc are that way). > > > X has to start after nouveau loads, otherwise it doesn't know about the > > nouveau adapter.

Depends on the "it" that you're talking about. You should be seeing NOUVEAU(GPU-0) messages in your xorg log if you start X after nouveau has loaded. Do you not?

OK, but that’s pointless here, I’ve choose this laptop after being sure that HDMI and mini-DP were wired to the Intel GPU. > > > X has to start after nouveau loads, otherwise it doesn't know about the > > > nouveau adapter.

I was talking of restarting X after loading nouveau, since I know no way to force nouveau to load at boot. I wasn’t seeing those lines, but I’ve figured out it was because of this section of the multiple xorg.conf files: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "Backlight" "intel_backlight" EndSection Since I’m currently not needing it (because in my actual configuration it has no effect, but that’s another story), I commented this out, and it does “work”, in the sense that I get the attached Xorg.0.log, and obviously the following lines in dmesg: [ 6509.306972] nouveau E[ PBUS][0000:02:00.0] MMIO write of 0x00000000 FAULT at 0x418880 [ IBUS ] [ 6509.307022] nouveau E[ PIBUS][0000:02:00.0] GPC0: 0x419eb4 0xbadf1000 (0x3800820c) [ 6509.307071] nouveau E[ PBUS][0000:02:00.0] MMIO write of 0x3f800000 FAULT at 0x405804 [ IBUS ] [ 6509.307263] nouveau E[ PIBUS][0000:02:00.0] HUB0: 0x404170 0x00000012 (0x0e008201) [ 6511.309246] nouveau E[ PGRAPH][0000:02:00.0] HUB_INIT timed out [ 6511.309254] nouveau E[ PGRAPH][0000:02:00.0] 409000 - done 0x00000204 [ 6511.309263] nouveau E[ PGRAPH][0000:02:00.0] 409000 - stat 0x00000000 0x00000000 0x00000000 0x00000000 [ 6511.309273] nouveau E[ PGRAPH][0000:02:00.0] 409000 - stat 0x00000000 0x00000000 0x00000002 0x00000009 [ 6511.309276] nouveau E[ PGRAPH][0000:02:00.0] 502000 - done 0x00000300 [ 6511.309281] nouveau E[ PGRAPH][0000:02:00.0] 502000 - stat 0x00000000 0x00000000 0x00000000 0x00000000 [ 6511.309285] nouveau E[ PGRAPH][0000:02:00.0] 502000 - stat 0x00000000 0x00000000 0x00000000 0x00000000 [ 6511.309287] nouveau E[ PGRAPH][0000:02:00.0] init failed, -16 Also: xrandr --listproviders Providers: number : 2 Provider 0: id: 0x69 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 6 associated providers: 0 name:Intel Provider 1: id: 0x3f cap: 0x5, Source Output, Source Offload crtcs: 0 outputs: 0 associated providers: 0 name:nouveau But after “xrandr --setprovideroffloadsink nouveau Intel”, “DRI_PRIME=1 glxinfo” results in X.org crashing with: [ 7519.419] (EE) [ 7519.419] (EE) Backtrace: [ 7519.419] (EE) 0: /usr/bin/Xorg.bin (xorg_backtrace+0x56) [0x594276] [ 7519.419] (EE) 1: /usr/bin/Xorg.bin (0x400000+0x1983c9) [0x5983c9] [ 7519.419] (EE) 2: /usr/lib/libc.so.6 (0x7f51e163a000+0x33b20) [0x7f51e166db20] [ 7519.419] (EE) 3: /usr/bin/Xorg.bin (0x400000+0x1632a4) [0x5632a4] [ 7519.419] (EE) 4: /usr/bin/Xorg.bin (0x400000+0x1632dd) [0x5632dd] [ 7519.419] (EE) 5: /usr/bin/Xorg.bin (DRI2Connect+0x3d) [0x56537d] [ 7519.419] (EE) 6: /usr/bin/Xorg.bin (0x400000+0x16611a) [0x56611a] [ 7519.419] (EE) 7: /usr/bin/Xorg.bin (0x400000+0x37807) [0x437807] [ 7519.419] (EE) 8: /usr/bin/Xorg.bin (0x400000+0x3b9a6) [0x43b9a6] [ 7519.419] (EE) 9: /usr/lib/libc.so.6 (__libc_start_main+0xf0) [0x7f51e165a040] [ 7519.419] (EE) 10: /usr/bin/Xorg.bin (0x400000+0x25dce) [0x425dce] [ 7519.419] (EE) [ 7519.419] (EE) Segmentation fault at address 0x28 [ 7519.420] (EE) Fatal server error: [ 7519.420] (EE) Caught signal 11 (Segmentation fault).

Oh, and thank you for you very quick answers and your help figuring this issue out!
