[SOLVED] Installing a Desktop Environment, Display Manager

I am trying to install LXQt and LightDM, similar to the wiki instructions

These were installed ok. I have an Nvidia hardware but use linux kernel rather than linux-lts, so I went with nvidia rather than nvidia-lts.
Code: [Select]
pacman -S xorg --ignore xorg-server-xdmx
pacman -S nvidia
pacman -S lxqt

but when it comes to the Diplay Manager, I don't know what to do. I cannot install displaymanager-openrc because I user runit. Should I then proceed just with lightdm or maybe lightdm-runit?
Code: [Select]
pacman -S lightdm-runit

The Arch wiki mentions that with lightdm I should also use a greeter, of which I would like to try the lightdm-webkit-theme-litarvan

So how should I proceedafter installing lxqt? How are all these DEs, DMs and greeters configured to work together?

Install your custom greeter and set the greeter-session variable in /etc/lightdm/lightdm.conf
Code: [Select]
greeter-session=lightdm-gtk-greeter

Ok, I installed lightdm-runit and also installed lightdm-webkit-theme-litarvan

I edited the lightdm.conf to use lightdm-webkit-theme-litarvan as greeter session.

I also told runit about the lightdm service:
Code: [Select]
ln -s /etc/runit/sv/lightdm /run/runit/service/

What now? I am still in the shell console. I tried a reboot, but except that Artix now uses a much wider shell font, nothing has changed.

I have no xinitrc in /etc/X11/xnit, so I could not copy it to ~. I created ~/.xinitrc with this content
Code: [Select]
exec lxqt-session

When I try to execute lxqt-session, I get this error:
Code: [Select]
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Aborted

Is this because I have not installed Qt? I did not install Qt explicitly, because I thought that if lxqt needs any qt components, it would install them as dependencies.

maybe missing libxcb?

Re: Installing a Destktop Environment, Display Manager

libxcb is already installed. I reinstalled it, just to make sure. I know I could probably just reinstall the system with the lxdm-runit ISO, but I found it appealing to install only the stuff I really need, so I went with the base package.

you can better use

exec dbus-launch lxqt-session

can you start now your lxqt session?


maybe /var/log/X.org.log can us help

Re: Installing a Destktop Environment, Display Manager

ok, I have changed the ~./.xinitrc but I still get the same error

Code: [Select]
exec dbus-launch lxqt-session

And I see that there I have no xorg log:
Code: [Select]
# ls -lA /var/log
total 224
drwx------ 2 root root     4096 Nov 14 10:42 audit
-rw------- 1 root utmp      768 Apr 19 18:48 btmp

-rw------- 1 root root    64064 Apr 21 05:02 tallylog
-rw-rw-r-- 1 root utmp    59520 Apr 21 05:02 wtmp

Can't find it anywhere else either:
Code: [Select]
# find / -iname "*\.log"
/var/log/dmesg.log
/var/log/lightdm/lightdm.log
/var/log/pacman.log

But I have installed xorg as it was in the wiki. Btw, do we still need to ignore xmdx?
Code: [Select]
pacman -S xorg --ignore xorg-server-xdmx

Ok, so try start xserver manually from terminal
Quote
startx
. Xserver will probably not starting due missing configuration, but  create Xorg.0.log.

If we will can start X server, we will start lightdm too.

Aha. We're closing in on the root cause.

Code: [Select]
startx
-bash: startx: command not found

you missing xorg-server ? :-)

pacman -S xorg-server

Re: Installing a Destktop Environment, Display Manager

Well, apparently, it's already installed

Code: [Select]
# pacman -S xorg-server
...
Total Installed Size: 3.50 MiB
Net Upgrade Size: 0.00 MiB

I reinstalled it, just in case, but startx is still not found.
