 Posted: Sun Oct 29, 2023 6:21 am Post subject: Trying to run a script before LightDM |
 |
|
Hello, i installed Gentoo and tried to install NVIDIA drivers, i was not getting any image(only blank screen on my laptop) but after i connected the HDMI all was working normally on the second screen, then i ran the command bellow and then i got image on both of my screens.
| Code: |
xrand --setprovideroutputsource modesetting NVIDIA-0
xrand --auto
|
I created a sh file usr/local/bin/prepare-optimus.sh, then made chmod +x to the file and added on lightdm config as bellow
| Code: |
#etc/lightdm/lightdm.conf
greeter-setup-script=/usr/local/bin/prepare-optimus.sh
|
but on the log of ligthdm it appears
| Code: |
#DEBUG: [LightDM] contains unkown option greeter-setup-script
|
How could I make this work?. thanks in advance |

You should have in lightdm.conf
| Code: |
display-setup-script=/usr/local/bin/prepare-optimus.sh
|
not
greeter-setup-script

Please post your full lightdm.log.
I suspect the problem is different.
Do you have a xorg.conf for nvidia?
Also plz pastebin your ~/.local/share/xorg/Xorg.0.log

Do you use a DE? I have a similar script (xmodmap not xrandr) to disable some mouse buttons in my homedir which I added to the startup and shutdown->autostart in kde, I'd imagine gnome/mate etc have something similar. I suppose you could add the xrandr commands to .bashrc as well.

Right now im using Xmonad with Lightdm, the problem is that there is only a black screen if there is no second monitor connected to my laptop. thanks why im trying to get the command execute before lightdm as in the manual, but lightdm conf doesnt recognize de parameter |

In the end it was because the display-setup-script or greeter-setup-script should be bellow [Seat:*], but even this could not get my laptop screen working |
