I have a 2-month-less-old harddisk, that shouldn't happen to me at all. I suspected Xorg, btrfs, chromium, firefox, but now I find the finnal solution. It's just because openSUSE's newly introduced btrfs snapshots manager "Snapper"! if you do not configure it yourself, by default it will snapshots and syncs your /, which is the whole disk, including /tmp! /var/tmp! /var/log! so I just edit /etc/snapper/configs/root and set SUBVOLUME to my home directory. Now the world is quiet and openSUSE is fast like sits on a rocket again. I think you guys should really reconsider this configuration and get it changed in later updates. If you can't even move a mouse on this computer, "data security" will be the least priority to you. Reproducible: Always Steps to Reproduce: just install it to a 1.73GHz computer and see. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
