I apologize for not being specific enough. I found a fix for this on my
machine, but I am unsure what options you may need that I have gathered
together to get things to work but found that I had missed replying to
this bug. I can post material more in depth as needed. Some of these
options helped me with other fixes for bbswitch. There are many options
for grub2 below, but mostly I wanted to mention the i915 material that
helps this bug.
I currently running:
* Linux 4.13.0-32-generic x86_64 GNU/Linux
* An MSI laptop with Intel HD Graphics 530 (Nvidia modules blacklisted so
bbswitch can load them as needed)
Added the following in my /etc/default/grub helping with this bug and disabling
Nvidia until bbswtich loads it ; note that 'acpi_osi' items may not be useful
on your system so search that part up as needed; note the '{your version #}'
meaning the package you have installed such as nvidia-384 or nvidia-387:
GRUB_CMDLINE_LINUX="nogpumanager
modprobe.blacklist=nouveau,nvidiafb,nvidia-modeset,nvidia-uvm,nvidia,nvidia-{your
version #} acpi_osi=! acpi_osi=\"Windows 2009\" intel_iommu=igfx_off
i915.semaphores=1 i915.enable_fbc=0 i915.modeset=1 i915.enable_rc=7
i915.enable_dc=2 i915.enable_ppgtt=3 i915.enable_guc_loading=1
i915.lvds_channel_mode=2 i915.lvds_use_ssc=1"
Added the following to /etc/modules :
i915
bbswitch load_state=0
Finally, ran the following manually to make sure things got updated:
sudo grub-mkconfig -o /boot/grub/grub.cfg
sudo grub-mkconfig -o /boot/efi/EFI/ubuntu/grub.cfg
sudo update-initramfs -u -k all
sudo update-grub2
