= Graphical interface (X11) == Configuring your graphics card If you install X, a /etc/X11/xorg.conf.d directory will be created for you, containing XOrg configuration fragment files. In most cases the default configuration will be enough for you, but you can place your own fragments there if you want to manually fine-tune some of the settings. A common problem is to use a keyboard layout different to the default of the locale, for example you have a non-English locale, thus the default keyboard layout isn't English, either, but you want to have such one. In that case you need to edit the evdev configuration: ---- # vi /etc/X11/xorg.conf.d/10-evdev.conf ---- and change the `xkb_layout` option there to `us`, for example. == 3D acceleration, binary drivers If there is built-in 3d acceleration support for your card in X, UDev will detect the necessary drivers and X will enable support for them. If you have an NVIDIA card, you probably need the manufacturer's binary drivers. Obtaining the NVIDIA binary driver is fairly simple: ---------------------- # pacman-g2 -Sy nvidia ---------------------- == Allow root login in KDM/GDM By default, no root login is permitted on the GUI, the recommended way of running graphical programs as root is to use gksu or kdesu. To enable it anyway, the following lines should be edited: For KDM ('/etc/kde/config/kdm/kdmrc') 'AllowRootLogin=false' modify to 'AllowRootLogin=true' For GDM ('/etc/gdm/gdm.conf') 'AllowRoot=false' modify to 'AllowRoot=true'
