Thanks for the report. So
- the kernel default and current value is 65530 - Fedora changed to 1048576 (https://src.fedoraproject.org/rpms/systemd/blob/rawhide/f/10-map- count.conf) which was enough according to their testing - you are suggesting 2147483642 , which is several order of magnitude higher Unsure if there are possible side effects or downside of having a too high value but it's late in the cycle and 1048576 seems like a more reasonable default @Julian I think from a Desktop perspective we are +1 on bumping to at least 1048576, technically that should be done in systemd I think.

Today, Hogwarts Legacy, Star Citizen and few more games are crashing or just not starting because the vm_max_map_count is locked at 65530. If we change this value to a value > 200000, all games are working well and there is no bug linked to maps. Some others distribution like Fedora or Pop OS, have already made the change few month before. It's time to Ubuntu to makes the change also. Thanks in advance for applying this request.
