[SOLVED] Can't start i3wm after setting Nvidia as main GPU

erfanjoker · 2020-12-23 02:18:28

Hi,
In continue to this topic, I was able to set Nvidia as my main GPU and I'm able to succesfully use GNOME with the prefered settings (using GDM)
But the problem is when i try to log into i3wm using GDM, I get a black screen and my VGA external monitor gets disconnected (like it's shutdown and recieves no input) and my laptop screen is just black (total black cause it's turned off, not the black with backlight)
In this step, i am able to access other TTY's and system is working properly, so it's not a HW issue, maybe a misconfiguration or etc, here is my journal : https://mega.nz/file/izRX2SDJ#iI-Ws5EYq … 1t6Adeisxc

I also have to mention that after Nvidia configurations, I was getting a fake VGA display detected in my system which was set as my primary display, I managed to disable it in gnome display settings in DE Level and is working fine, also in Startup Manager Level like GDM, i used this workaround by turning it off :

^^>>> cat /etc/X11/xorg.conf.d/11-monitor.conf                     05:45:33 
Section "Monitor"
	Identifier "VGA-0"
	Option	"Ignore"	"True"
EndSection

And here is my .xsession file :

^^>>> cat ~/.xsession                                              05:28:19 
xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

My guess is it has something to do with the /etc/X11/xorg.conf.d/11-monitor.conf as it's turning of the VGA-0,
I don't know what mechanism does i3wm use for handling displays, but i was not really able to save my monitors config in i3wm ever, I always had issues and used to do a config after reboot using arandr.

Post your i3 config.
I'm not sure whether GDM executes ~/.xsession

Edit, and please use code tags or ix.io, not some mega drive where one has to download files

Thanks, but for some reasons my config file is getting re-written everytime i boot ! Thus i have never tried editing config file for startup stuffs, as i always add keyboard layout by using setxkbmap manually, i always added this to config file and on the next reboot it was gone !

Is there anyway convert arandr config to xrandr command ? or force xrandr to use arandr config ?

Archlin · 2020-12-23 15:01:14

That your config gets overwritten (every time) when you reboot that's kinda odd.
I must confess I never seen such a behavior but it seems to me to get that fixed at first.

I also never used arandr but is is not a graphical front end for the CLI xrandr?

I would like to fix it, and im planning to start a new thread for that, but first i have to get it to work properly on my screen
arandr is GUI for xrandr, but its changes are instant as it applies via running command, it also can generate config file but not at the default config directory of xrandr, It just generates bash script and needs to run at startup (I prefer config file, to startup exec command)

Do you use some overlay FS for your $HOME?

About the i3 config, there's no randr call in that.
Since I don't think that GDM cares about ~/.xsession, add a PreSession script to setup the randr config, https://help.gnome.org/admin/gdm/stable … on.html.en
This will be required because GDM launches a second X11 server for the session.

Alternatively just drop GDM…

I disabled GDM service and enabled Lightdm Rebooted and oops, the same as i3wm, when it enters GUI, it just turns off monitors and uses it's dream fake monitor, the thing is GDM and Gnome may use something other than system default monitor config

Here is my correct xrandr config :

xrandr --output LVDS-1-1 --mode 1366x768 --pos 1920x0 --rotate normal --output VGA-1-1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output HDMI-1-1 --off --output DP-1-1 --off

Where could i just add this command to get Lightdm, or i3wm working ?
I placed it in i3wm config file and set its permission to 444 so it wont get overwritten, then logged into i3, and the same result, like it is not executing this config file, or sth else

Thats why i dont really like executing xrandr command and prefer a global config file

That part has nothing to do w/ GDM and I would eye more sth. like xinit/startx…
If I should name a DM that's even worse than GDM it'd likely be lightdm…

Where could i just add this command to get Lightdm … working ?

https://wiki.archlinux.org/index.php/Li … ng_monitor

I placed it in i3wm config file

Placed it "how"?

You can just add those outputs w/ the desired config to your /etc/X11/xorg.conf.d/11-monitor.conf ?

man xorg.conf

Thanks for answering, I added the command directly to i3wm config file, then i figured out i have to use "exec Command" and it did the trick

Glad it worked

Guess you did not see the last line in my example which should have pointed that out.
