dmesg

On every boot, there is a kernel WARNING related to Xorg. The WARNING line is:

[  142.852681] WARNING: CPU: 0 PID: 1584 at mm/filemap.c:221
unaccount_page_cache_page+0x12b/0x180

This warning is always related to the Xorg process. I don't know if this
WARNING is harmful, but it happens on every boot.

As the system is Xubuntu 18.04, Xorg version being used is 1.19.6. Kernel is
drm-tip and Mesa is git.

Processor: Intel Core i3-6100U;
Video: Intel HD Graphics 520;
Architecture: amd64;
Mesa:  19.3.0-devel (git-c7e5d24d8f);
