• Dell XPS 13 (9350) - Bottom edge of videos flickering


    https://wiki.archlinux.org/index.php/Dell_XPS_13_(9350)
    There is no such cocumented at the archwiki, and this is exact your model…
    But as you already know there are some others with the same artifacts inside chromium e.t.c.
    The problem under GNOME/Wayland is that the compositor almost have no configuration possibilities, so you can only get around by options directly injected to the driver.

    • kernel parameters
      one of the following options may help i915.enable_rc6=1 i915.enable_fbc=1 i915.enable_guc_loading=1 i915.enable_guc_submission=1 you can find this options on ArchWiki + one of the answears on reddit say that this is a working way nto get around he problem.

    • /etc/X11/xorg.conf.d/20-intel.conf
      Do you try already to create this and adding the tearfree option?

    Section "Device"
      Identifier  "Intel Graphics"
      Driver      "intel"
      Option "TearFree" "true"
    EndSection
    

    are the two places where you can do this.

  • Hey @joekamprad,

    I did the 2nd option (creating the 20-intel.conf file), and performed a reboot, but the problem persists unfortunately.

    For adding the kernel parameters to GRUB, should I follow the steps in the following document to add the ones you defined in your post:

    Thanks again for all of your time and help so far, it is greatly appreciated @joekamprad !

    Thanks,
    Asif

    Adding and experimenting with kernel boot parameters is easiest done by writing a menuentry into file /boot/grub/custom.cfg.

    Simply copy the relevant menuentry from your current /boot/grub/grub.cfg into this custom.cfg, and add kernel parameters on the line starting with word “linux”.

    Additionally, you can make the menuentry simpler by removing all unnecessary stuff there.

    Here are some examples of menuentries in custom.cfg:
    https://forum.antergos.com/topic/9039/grub-boot-examples-custom-cfg

    Maybe this is close to what you need:

    menuentry "Antergos LTS" {
        savedefault
        set kernel=linux-lts   # or remove the "-lts" suffix if you use the default kernel
        search --set --file /boot/vmlinuz-$kernel
        probe -u $root --set=uuid
        linux  /boot/vmlinuz-$kernel root=UUID=$uuid rw quiet
        initrd /boot/intel-ucode.img /boot/initramfs-$kernel.img
    }

    Edit /etc/default/grub and append your kernel options to the GRUB_CMDLINE_LINUX_DEFAULT line:
    sudo nano /etc/default/grub

    GRUB_CMDLINE_LINUX_DEFAULT="quiet i915.enable_rc6=1 i915.enable_fbc=1 i915.enable_guc_loading=1 i915.enable_guc_submission=1 resume=***"
    

    save with [Ctrl+X]
    And then automatically re-generate the grub.cfg file with:

    sudo grub-mkconfig -o /boot/grub/grub.cfg
