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 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1660619 Title: kernel: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe B To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1660619/+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
