 If you also want to increase reliability further, you can make a dependency/cache check with "sudo apt-get check", which is normally very quick.
 For that, under debian/whonix do: `sudo apt-get check && sudo apt-get update -t *-testing && sudo apt-get dist-upgrade -t *-testing`.

+### How do I change display resolution on a Linux HVM?
+
+You only get one resolution at a time.
+In the HVM's `/etc/X11/xorg.conf`, in Subsection "Display" for Depth 24, make a single mode like this:
+
+~~~
+...
+    Subsection "Display"
+        Viewport 0 0
+        Depth 24
+        Modes "1200x800"
+    EndSubSection
+EndSection
+~~~
+
+Only some modes will work. check wikipedia. if your host display is
+1080p(1920x1080), then an hvm at 1440x900 works well. if its more than that, might
+as well do 1080p in the hvm.
