Fix [drm:intel_pipe_update_start [i915]] *ERROR* Potential atomic update failure on pipe B in Fedora
Raw
workarround.md

To solve screen is flickering

sudo -e /etc/default/grub

Add i915.enable_psr=0 to GRUB_CMDLINE_LINUX="...... i915.enable_psr=0"

For BIOS systems:

sudo grub2-mkconfig -o /boot/grub/grub2.cfg
reboot

For UEFI systems:

sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
reboot

To check if it's working:

for i in /sys/module/i915/parameters/*;do echo ${i}=`sudo cat $i`;done

Also it helps to disconnect and connect the HDMI cable, it works for a while.
