Rotating the linux console with Intel HD graphics

I've never gotten this to work with Nvidia cards, but with my mac mini with Intel Iris graphics, you can: /bin/echo "3" > /sys/devices/virtual/graphics/fbcon/rotate To rotate the display counter-clockwise 90 degrees, which is very helpful if you are trying to restore a system with monitors in portrait mode.

Failure at installing Fedora 20 on a mac mini

This was an attempt to put Fedora 20 on a 2008-ish mac mini. Even though this box has a 64-bit processor, it has 32-bit EFI.  Fedora installers come in 1 of 2 configurations: 64-bit EFI / x86_64 32-bit Bios /  i686 Rather than go through the rigmarole of wrapping my own 32bit EFI with x86_x64, I went with the easy approach of 32-bit Bios + i686.  The box only has 2GB of RAM, so I am not really missing out on anything. I've grown quite accustomed to XFCE so I downloaded the i686 spin: http://download.fedoraproject.org/pub/fedora/linux/releases/20/Live/i386/Fedora-Live-Xfce-i686-20-1.iso Download and installed base system Post installation configuration: systemctl enable sshd.service systemctl start sshd.service yum -y update yum -y install vim-enhanced yum -y install yum-plugin-keys yum-plugin-fastestmirror yum-plugin-remove-with-leaves yum-plugin-show-leaves yum-plugin-verify yum  -y install xfce4-cpufreq-plugin xfce4-icon-theme xfce4-volumed xfce-the...
