 Posted: Tue Jul 29, 2014 2:42 pm Post subject: [solved] gdm 3.12.2 and Nvidia Optimus |
 |
|
When I launch gdm (systemctl start gdm), I end up with a black screen. The same happens when I run xinit. This xorg.conf worked well with Xfce4.
Here is my ~/.xinitrc:
| Code: |
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto
exec gnome-session
|
Here is my /etc/X11/xorg.conf:
| Code: |
Section "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
Inactive "intel"
EndSection
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
EndSection
Section "Screen"
Identifier "nvidia"
Device "nvidia"
Option "AllowEmptyInitialConfiguration"
EndSection
Section "Device"
Identifier "intel"
Driver "modesetting"
EndSection
Section "Screen"
Identifier "intel"
Device "intel"
EndSection

How do I notify GDM that I am using optimus? Do I need to edit something in the /etc/gdm/ directory?
Solution:
I was able to resolve this issue by editing my /etc/gdm/Init/Default to contain the necessary xrandr lines:
| Code: |
#!/bin/sh
# Stolen from the debian kdm setup, aren't I sneaky
# Plus a lot of fun stuff added
# -George
PATH="/usr/bin:$PATH"
OLD_IFS=$IFS
## THESE ARE THE LINES THAT I ADDED!
exec xrandr --setprovideroutputsource modesetting NVIDIA-0
exec xrandr --auto
gdmwhich () {
COMMAND="$1"
OUTPUT=
IFS=:
for dir in $PATH
do
if test -x "$dir/$COMMAND" ; then
if test "x$OUTPUT" = "x" ; then
OUTPUT="$dir/$COMMAND"
fi
fi
done
IFS=$OLD_IFS
echo "$OUTPUT"
}
sysresources=/etc/X11/Xresources
# merge in defaults
if [ -f "$sysresources" ]; then
xrdb -merge "$sysresources"
fi
sysmodmap=/etc/X11/Xmodmap
XMODMAP=`gdmwhich xmodmap`
if [ "x$XMODMAP" != "x" ] ; then
if [ "x$GDM_PARENT_DISPLAY" = "x" ]; then
if [ -f $sysmodmap ]; then
$XMODMAP $sysmodmap
fi
else
( DISPLAY=$GDM_PARENT_DISPLAY XAUTHORITY=$GDM_PARENT_XAUTHORITY $XMODMAP -pke ) | $XMODMAP -
fi
#

if [ "x$PROCESSOR" = "xsparc" ]; then
if $XMODMAP | grep mod4 | grep Alt > /dev/null 2>/dev/null
then
$XMODMAP -e "clear Mod1" \
-e "clear Mod4" \
-e "add Mod1 = Alt_L" \
-e "add Mod1 = Alt_R" \
-e "add Mod4 = Meta_L" \

fi
fi
fi
SETXKBMAP=`gdmwhich setxkbmap`
if [ "x$SETXKBMAP" != "x" ] ; then
# FIXME: is this all right? Is this completely on crack?
# What this does is move the xkb configuration from the GDM_PARENT_DISPLAY
# FIXME: This should be done in code. Or there must be an easier way ...
