Public bug reported:
On my laptop (Clevo P650RA) with Skylake / Intel Core i7 6700HQ with
Intel HD Graphics 530 IGP and a nvidia GTX965M DGP, glxinfo crashes when
running in IGP mode,
The laptop uses Optimus / MSHYBRID technology to be able to utilize both
IGP and DGP.
After setup I install nvidia-361 driver, which will make the system run
using DGP mode by default. Using prime-select intel I can switch to
using the IGP. After logging out and in again, the IGP is being used.
However, when doing certain tasks, the system will crash. Running
glxinfo is one of them. Another one is:
cat /proc/acpi/bbswitch
In addition, it sometimes seemingly at random, probably when some kind
of desktop effect is performed. It seems that some kind of interaction
with ACPI / IGP will make it crash.
This is running Kubuntu 16.04 Xenial Beta 2.
Some version numbers:
Kernel version (uname -r): 4.4.0-18-generic
linux-image-4.4.0-18-generic: 4.4.0-18.34
xserver-xorg-core: 2:1.18.3-1ubuntu2
xserver-xorg-video-intel: 2:2.99.917+git20160325-1ubuntu1
sddm: 0.13.0-1ubuntu5
plasma-desktop: 4:5.5.4-0ubuntu1
lsb_release -a:
Distributor ID: Ubuntu
Description: Ubuntu Xenial Xerus (development branch)
Release: 16.04
Codename: xenial
I'll attach a kern.log and a Xorg.0.log from a Intel IGP session on this
laptop. Please let me know if I should provide other information, and
how to collect this after a full system freeze.
