I think the above link will not gonna help because it's related to computer freezing when RAM is full, my computer wasn't with high usage of RAM on the freeze moment, it was using something about 50%
Another point is that zram makes computer use less RAM and my problem gone when I uninstalled zram, so the issue definitely is not related to high memory usage -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1809556 Title: zram freezes computer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1809556/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
