# Vi0L0: it's my switching script, version 2.1:
# * switching xorg.conf - it will rename xorg.conf into xorg.conf.cat
#   (if there's fglrx inside) or xorg.conf.oth (if there's intel or radeon inside).
#   And then it will create link to xorg.conf depending on what did you choose
# * running aticonfig --px-Xgpu
# * running switchlibGL
# * adding/removing fglrx into/from /etc/modules-load.d/catalyst.conf
#
# You can do with it whatever you want :P
# NO WARRANTY OF ANY KIND

# Set local language always to C
export LC_ALL=C
