You appear to have bbswtich referenced in your dmesg. Bumblebee is more likely to just mess things up, and adds nothing over the runtime pm functionality present in nouveau since 3.12 or so. [There are situations where that's not working for one reason or another, but this is the minority of situations.] Do you have customized xorg.conf settings? If so, try moving them out of the way. (I notice that you're probably explicitly loading glamoregl -- no reason to do that, can only cause trouble...) Probably the big difference between 1.15 and 1.16 is DRI3, perhaps something is going wrong there... you could either try a git xf86-video-intel ddx or disable DRI3 (either at build time or with Option "DRI" "2" in the driver section). However I'm moderately sure this has worked fine for others. DRI3 does not work "out of the box", you'd need some work. But for now try disabling DRI3! Looks like for prime + dri3 to work, you need render nodes. I thought they were enabled by default in 3.16, but that is not the case. You can enable them by adding "drm.rnodes=1" to the kernel cmdline. Or you can upgrade to 3.17. Upgrading to kernel 3.17, or booting 3.16 with drm.rnodes=1 do not make it work. Recompiling xorg-server 1.16 without dri3 make it work. A last note: for DRI3 you dont have to do the xrandr --listproviders xrandr --setprovideroffloadsink nouveau Intel dance anymore, it works without! You can disable the compositor as well with DRI3. Closing as fixed, feel free to reopen if something is still unclear. |
