FWIW: today I installed kernel 4.6.0-040600-generic from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.6-yakkety/ on my Kubuntu Xenial setup. On this kernel version the nvidia-drivers I was using, nvidia-361, didn't work anymore (it said that kernel 4.6.0 was not supported), so I upgraded to nvidia-464 from https://launchpad.net /~graphics-drivers
After this I had one more glitch, that is that even though nouveau is listed in /etc/modprobe.d/nvidia-graphics-drivers.conf as blacklist nouveau blacklist lbm-nouveau it would still be loaded, preventing the nvidia driver from working properly. By adding nouveau.blacklist=1 to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub I could prevent it from loading. Using this combination, I now have a fully working optimus setup. I can switch using nvidia-settings between nvidia and intel graphics and both run equally stable. It seems this issue was fixed in kernel 4.6.0 (possibly related to kernel bug https://bugzilla.kernel.org/show_bug.cgi?id=109081). I'm fairly certain that the newer nvidia driver doesn't influence it as even without that, the intel driver would work fine on 4.6.0. I just couldn't switch to the nvidia GPU. Will kernel 4.6.x make it into Xenial at some point? It seems that it's might be required for Skylake laptops to work completely. ** Bug watch added: Linux Kernel Bug Tracker #109081 http://bugzilla.kernel.org/show_bug.cgi?id=109081 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1569383 Title: Intel HD Graphics 530 crashes on glxinfo in MSHYBRID mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1569383/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
