Intel Xorg driver in Fedora 27 does not have UseEdidDpi and DPI options

I’ve “always” set the Xorg DPI value to a lower value than the default. On Fedora 27 this
didn’t any more work through /etc/X11/xorg.conf.d/xorg.conf.

How to add a new virtual console resolution for a VirtualBox VM?

On VirtualBox host:

$ VBoxManage setextradata "VM name" "CustomVideoMode1" "1400x1050x16"

On VirtualBox VM’s grub boot loader stage, press ‘e’ and add “vga=864” as a new kernel parameter.

If you add an invalid value for vga, i.e. vga=871, you’ll get the list of available resolutions.

Edit 20180316: It seems that vga= expects the value in decimal but the Linux kernel converts the value to hex.

How to convert values from decimal to hex:

$ echo -e "obase=16 \n 864 \n" | bc -l
