Description of problem: Intel Haswell controller (HD 4600) which feeds 3D rendering to a back-end nVidia chip (GK107GLM [Quadro K1100M]). The nvidia chip used to be listed as a provider under xrandrx and available for Source Offload. It is not longer listed.

Hi, Can you please do (directly after boot): dmesg > dmesg.log And then attach dmesg.log here ? Also please attach a recent Xorg.0.log here, likely you will find it in ~/.local/share/xorg/Xorg.0.log . Regards, Hans

For some reason nouveau does not seem to load at all, do you perhaps have a *.conf file in /lib/modprobe.d or /etc/modprobe.d leftover from an nvidia driver install which contains "blacklist nouveau" ? Also try regenerating your initrd. Can you do "lsmod | grep nouveau" and see if it outputs anything ? If not try explicitly loading nouveau with: "modprobe nouveau"

Thanks for looking into this, Hans! Do you mean regenerate initramfs (with dracut)? nouveau is not loaded (output below). If I load nouveau before starting x, no difference. (Will test again). How else can I help? ---- # lsmod | fgrep nouveau # modprobe nouveau # lsmod | fgrep nouveau nouveau 1564672 0 ttm 94208 1 nouveau mxm_wmi 16384 1 nouveau i2c_algo_bit 16384 2 nouveau,i915 drm_kms_helper 151552 2 nouveau,i915 drm 339968 13 nouveau,i915,ttm,drm_kms_helper video 40960 5 dell_wmi,dell_laptop,int3406_thermal,nouveau,i915 wmi 16384 3 dell_wmi,mxm_wmi,nouveau

I guess the nvidia hardware not showing in dmesg means that it is not found at boot. That seems like the biggest clue. I have tried loading the nouveau module before starting x (gdm), no change in the Xorg.0.log output.
