Static Multi-monitor setup - Desktop Scrambled at startups - xfce-pbw.sh makes it worse

I think this is the solution. In my environment, there is graphic support in the Intel processor and there is a pci video card. All the monitors are connected to the pci video card. Blacklisting i915 module in /etc/modprobe.d/99-no-i915.conf seems to have solved the monitor/output identifiers changing from boot to boot.

/etc/modprobe.d/99-no-i915.conf

A better way to disable i915 is to add module_blacklist=i915 to the kernel boot parameters in GRUB_CMDLINE_LINUX_DEFAULT found in /etc/default/grub.

The original solution became unstable after latest update.
