Display manager problems

[Tomosius]

Hello,

Sorry i am having again few questions:

Id i use nvidia optimus, and use xorg.conf with my custom setup and .xinitrc, it is fine, i can use optimus with XRAND settings:
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

but problem starts here:
if i try to setup any of these managers, that support xrandr commands (i tried all i could find display managers, even kdm), all of them give me black screen and xfce4 is not loading. i would say it is quite strange, because startx is working, optimus is working. what could be wrong?

xorg.conf:
ection "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
Inactive "intel"
EndSection

Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:01:00:0"
EndSection

Section "Screen"
Identifier "nvidia"
Device "nvidia"
# Uncomment this line if your computer has no display devices connected to
# the NVIDIA GPU. Leave it commented if you have display devices
# connected to the NVIDIA GPU that you would like to use.
Option "UseDisplayDevice" "none"
EndSection

Section "Device"
Identifier "intel"
Driver "modesetting"
EndSection

Section "Screen"
Identifier "intel"
Device "intel"
EndSection




P.S.: i have no idea, but in section "BusID "PCI:01:00:0" i had to put this way, because BusID "PCI:01:00.0" was not working. maybe this is a problem?

lightdm works well. The xrandr setup script goes into /etc/lightdm/lightdm.conf:display-setup-script

Hi Nell,

Than you for reply, but it does not work, as i have mentioned above. it is very strange for me, but it does not work...
i have looked on Gentoo wiki, arch linux wiki, all those Display managers... nothing works.....
but startx is fine, and i get it working when try to run test: glxspheres64.

Tonight i will try to recompile all system and tomorrow will give another try.
