 |
|
Hello there,
I'm playing around with some desktop environments at the moment.
After installing dwm, I was not able to start Xorg server via .
It doesn't matter if I'm emerging the gentoo package of dwm or compiling it directly from the suckless sources.
My .xinitrc in my home-directory only contains
| Code: | | exec dwm > .dwm.log |
It shows the error
| Code: |

Starting X with root privileges works, but I think that's not the appropriate way of handling this problem.
tty7 has 620 privileges, same as every other terminal. My user is part of video, input, users, and tty group.
No display manager like lightdm is running as a service.
xorg-server is compiled with elogind, xorg, ipv6 and udev flag.
I hope someone has an idea...
Thanks in advance!

| This looks like the usual problems with elogind. Your Xorg server needs elogind to help it get control of the terminal, and for some reason, that is not happening. What is the output of rc-update show | grep elogind ; loginctl list-sessions, when logged in at the text console as your user (not root)? |

for tty7 to work for groups the permissions would need to be 660 and for all users 666 (6 because the terminal needs to be written to)
Or alternatively you could do startx -- vt1 (assuming you're on console 1)

elogind | boot
SESSION UID USER SEAT TTY
4 1000 <username> seat0
1 sessions listed.

| That is the good output, and seems to show that elogind is working correctly. My guess was incorrect. I have no further advice at this time. Hopefully, someone else can help you solve this. |

Thanks anyway.
I figured it out myself... or at least partially.
I followd the post of | Anon-E-moose wrote: | | startx -- vt1 |
to start X via another terminal, this works just fine.
Anyway I figured out that when I switch to tty7 there is no login screen, just a black screen with a blinking cursor. It seems that some service or something else is using this terminal...
Thank you both!

If elogind is set up correctly, when you log in on a tty, the environment should automatically have variable XDG_VTNR set to the tty number. If you are using Gentoo's /etc/X11/xinit/xserverrc file, it should be passing a -keeptty option and a correct vtn argument to Xorg if XDG_VTNR is set and not empty, without you having to specify any arguments in the startx invocation. Somehow this is not happening here.

Yes. because you worked around the problem by passing the vtn argument yourself.

Yes, because Xorg has taken tty1. Nothing is using tty7. Xorg takes an unused tty only when running as root. |

Is rc_tty_number in /etc/rc.conf modified to a lower number then 7? |
No, it's set to 12.

I think I get your point. XDG_VTNR is not set in my system, so it's using vt1 as an argument. How can I fix this behavior?
Your said "correctly configured elogind" - what is the correct setup?

It isn't? Can you post the output of loginctl show-session <session identifier> and env | grep XDG_? <session identifier> is the identifier that loginctl with no arguments shows for the tty you used to log in, i.e. "4" in your previous output (it can change each time you log in):
| HansHelm wrote: | | Code: | SESSION UID USER SEAT TTY

1 sessions listed. |

(I just noticed that the "TTY" column was empty, is that a typo?)
For example, on my computer:
| Code: | $ loginctl
SESSION UID USER SEAT TTY
c1 1000 <my username> seat0 tty1
1 sessions listed.
$ loginctl show-session c1
Id=c1
User=1000
Name=<my username>
Timestamp=Mon 2021-03-08 22:15:33 -03
TimestampMonotonic=21782878
VTNr=1
Seat=seat0
TTY=tty1
Remote=no
Service=login
Leader=500
Audit=4294967295
Type=tty
Class=user
Active=yes
State=active
IdleHint=no
IdleSinceHint=1615252728693999
IdleSinceHintMonotonic=217003261

$ env | grep XDG_
XDG_SEAT=seat0
XDG_SESSION_TYPE=tty
XDG_SESSION_CLASS=user
XDG_VTNR=1
XDG_SESSION_ID=c1
XDG_RUNTIME_DIR=/run/user/1000 |
As you can see, XDG_VTNR is there. |
