Mudar a resolução
Sem nenhuma configuração, meu Awesome
atribuía resoluções ruins para o monitor do meu notebook
(LVDS1
) e da TV ligada ao HDMI:
julio@julio-acer ~> xrandr -q
Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192
LVDS1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 293mm x 164mm
1366x768 60.0 +
1024x768 60.0*
800x600 60.3 56.2
640x480 59.9
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 connected 1024x768+0+0 (normal left inverted right x axis y axis) 160mm x 90mm
1920x1080 60.0 + 60.0
1280x1024 60.0
1280x720 60.0
1024x768 60.0*
800x600 60.3
640x480 60.0 59.9
720x400 70.1
DP1 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
TV1 unknown connection (normal left inverted right x axis y axis)
848x480 30.0 +
640x480 30.0 +
1024x768 30.0
800x600 30.0
Para consertar, utilizei o seguinte comando:
julio@julio-acer ~> xrandr - -output HDMI1 --auto
julio@julio-acer ~> xrandr - -output LVDS1 - -auto
Como não preciso usar o monitor do notebook eu posso desligá-lo usando:
xrandr - -output LVDS1 - -off
Scripts
xrandir
Salve o seguinte script em ~/Scripts/monitores
e adicione ao .xinitrc
:
#!/bin/bash
EXTERNAL_OUTPUT="HDMI1"
INTERNAL_OUTPUT="LVDS1"
# EXTERNAL_LOCATION may be one of: left, right, above, or below
EXTERNAL_LOCATION="right"
case "$EXTERNAL_LOCATION" in
left|LEFT)
EXTERNAL_LOCATION="--left-of $INTERNAL_OUTPUT"
;;
right|RIGHT)
EXTERNAL_LOCATION="--right-of $INTERNAL_OUTPUT"
;;
top|TOP|above|ABOVE)
EXTERNAL_LOCATION="--above $INTERNAL_OUTPUT"
;;
bottom|BOTTOM|below|BELOW)
EXTERNAL_LOCATION="--below $INTERNAL_OUTPUT"
;;
*)
EXTERNAL_LOCATION="--left-of $INTERNAL_OUTPUT"
;;
esac
xrandr |grep $EXTERNAL_OUTPUT | grep " connected "
if [ $? -eq 0 ]; then
xrandr --output $INTERNAL_OUTPUT --off --output $EXTERNAL_OUTPUT --auto $EXTERNAL_LOCATION
else
xrandr --output $INTERNAL_OUTPUT --auto --output $EXTERNAL_OUTPUT --off
fi

Xorg
Outro modo é editar o /etc/X11/xorg.conf
. Só que por algum motivo a segunda tela fica com
resolução errada:
