Hey folks, since kernel 4.6.2 I got a lot of X11 freezes as well as unusable gui tools (delayed inputs, scrolling and broken display rendering). Also all the virtual box clients are behaving the same. Only the chromium gui and xterm were usable (well, xterm only on my host, not on the virtual box clients).
I tried my best and here are the changes I made that stopped the system from a total freeze since four days:
I just got the following entry on my boot up today:
systemd[1]: Failed to start Create Volatile Files and Directories.
After a while of searching using my favorit searchengine, I (as usual ;-)) found the most fitting solution in the bbs.archlinux.org.
The solution is given in the manpage of the tmpfiles.d.
tmpfiles.d(5) wrote:
If the administrator wants to disable a configuration file supplied by the vendor, the recommended way is to place a symlink to /dev/null in /etc/tmpfiles.d/ bearing the same filename.
So all you have to do is:
# sudo su
# cd /usr/lib/tmpfiles.d
# cp journal-nocow.conf journal-nocow.conf.bak
# rm journal-nocow.conf.bak
# ln -s /dev/null journal-nocow.conf
And thats it. Fingers crossed you system will boot without errors.
