Most current documentation on the Internet states that the correct way to disable the GNOME Shell screensaver is to simply set idle-activation-enabled to false: $ gsettings set org.gnome.desktop.screensaver idle-activation-enabled false With Fedora 19, changing idle-activation-enabled to false does not stop the screen from dimming and locking your screen. In Fedora 19, this key is marked deprecated and ignored. You have to set org.gnome.session.idle-delay to 0 if you do not want to activate the GNOME Shell screensaver. $ gsettings set org.gnome.desktop.session idle-delay 0

It you are using a PAE (Physical Address Kernel) kernel in a Virtual Box guest and wish to install the VirtualBox Guest additions, you need to download the kernel-PAE-devel package as well as the kernel-headers package. PAE kernels are available for Fedora, Red Hat, CentOS and more. Otherwise you will end up failing to build the main Guest Additions kernel module and getting a misleading message in /var/log/vboxadd-install.log after attempting to run sh ./VBoxLinuxAdditions.run: *** Error: KERN_DIR does not point to a directory. That message is misleading as the real error is due to you not having the PAE headers Either of the following two methods will install and configure the VirtualBox Guest Additions on Debian Wheezy (7.0 or 7.1) – assuming you have clicked on “Install Guest Additions” option on the VM Menu. # apt-get update # apt-get install build-essential module-assistant # m-a prepare # mount /media/cdrom # bash /media/cdrom/VBoxLinuxAdditions.run or # apt-get update # apt-get install gcc make # apt-get install linux-headers-$(uname -r) # mount /media/cdrom # bash /media/cdrom/VBoxLinuxAdditions.run Contrary to what some people have experienced, I had no trouble invoking the GNOME 3 Shell in Debian 7.0 or 7.1 when running in VirtualBox 4.2.16 under Microsoft Windows |
