[all variants] ext4 option "data=writeback" makes breaks my system

latebeat

Hi there,
I'm new to linux so please forgive me if my questions are kinda "naive" or stupid!
I've read an article on how to speed-up ext4 by using the following options when mounting:

Code:

defaults,data=writeback,noatime,barrier=0,extents,journal_checksum

This is just a test pc, not my main pc so I don't mind the instability issues or the consequences of enabling writeback cache.
All other options work fine however when I add data=writeback in the /etc/fstab for my root partition the system doesn't boot with the following error:

Code:

Could not start the X server due to some internal error. blabla, please restart gdm when the problem is corrected

Any ideas on how to correct this and enable writeback cache?
