ly display manager does not render correctly (running in tty2)

山猿 · 2023-07-29 22:15:21

Hello,

I am running Arch Linux with bspwm and ly. I have recently removed lightdm and replaced it with ly (see the base config file here). As I understand it, ly pulls from .xinitrc to render. At the moment, my .xinitrc file looks like this:

#!/bin/sh

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap


xrandr --output HDMI-0 --primary --mode 1920x1080 --rotate normal --output DP-1 --mode 1920x1080 --rotate normal --above HDMI-0 --output DP-3 --mode 1920x1080 --rotate normal --right-of DP-1 --output DP-5 --mode 1920x1080 --rotate normal --right-of HDMI-0

# merge in defaults and keymaps

if [ -f $sysresources ]; then







    xrdb -merge $sysresources

fi

if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi

if [ -f "$userresources" ]; then







    xrdb -merge "$userresources"

fi

if [ -f "$usermodmap" ]; then
    xmodmap "$usermodmap"
fi

#xrdb ~/.Xresources

# start some nice programs

if [ -d /etc/X11/xinit/xinitrc.d ] ; then
 for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do
  [ -x "$f" ] && . "$f"
 done
 unset f
fi

playerctld daemon &

wal -R

#xclock -geometry 50x50-1+1 &
#xterm -geometry 80x50+494+51 &
#xterm -geometry 80x20+494-0 &
#exec xterm -geometry 80x66+0+0 -name login

exec bspwm &

I have ensured that this file is executable, as suggested by the README on the ly github page. However, the line involving xrandr:

xrandr --output HDMI-0 --primary --mode 1920x1080 --rotate normal --output DP-1 --mode 1920x1080 --rotate normal --above HDMI-0 --output DP-3 --mode 1920x1080 --rotate normal --right-of DP-1 --output DP-5 --mode 1920x1080 --rotate normal --right-of HDMI-0

does not appear to do anything. I have tested this by placing the same line in my bspwmrc file and commenting it out; my display only renders correctly when this is uncommented, irrespective of whether the line in .xinitrc is commented or not.

Interestingly enough, I believe that the line above did work in .xinitrc when I was using lightdm. I am not sure if this is because ly runs within tty2 or if it is something else entirely. I found also that my mouse is using the default X cursor icon instead of the now common black arrow from Adwaita. Any help you could provide would be much appreciated, thank you.

Issue partially solved by doing the following:

Edit /etc/default/grub as follows:

/etc/default/grub
...
GRUB_GFXMODE=1920x1080
GRUB_GFXPAYLOAD_LINUX=keep
...

Update the grub file by running this command:
```
sudo grub-mkconfig -o /boot/grub/grub.cfg
```

The boot loader now displays the correct resolution, as does the display manager. My other screens, however, remain off until I launch into my windows manager, bspwm.

When I run xrandr -q, I am given the following output:

Screen 0: minimum 8 x 8, current 3840 x 2160, maximum 32767 x 32767

   720x480       59.94  
   640x480       59.94    59.93

So as I understand it, a 'screen' does exist, treating my square of 4 1920x1080 monitors as a single 3840x2160 panel (if I understand right), allowing me to, for instance, tile a feh image as a background across all 4 screens, as if the image was stretched across them. Is there a way to do this for GRUB and (or least, if not both) the ly display manager? I do know that I managed to display all 4 screens via lightdm. Thank you.
