xinit: XFree86_VT property unexpectedly has 0 items instead of 1

[IanTrudel]

InfiniteGlass fails to start withtin Xephyr, see log below. There might be some dependency for InifiniteGlass missing on my machine but Xephyr runs fine on its own. I have tried with and without an external monitor attached.

That is very strange. If you run Xephyr w just a terminal in it, does it work? If you then start glass-renderer from the terminal, does that trigger the bug?

[IanTrudel]

No, it doesn't. I'm getting a black screen though. There was an xterm opened and it seems to be behind the black screen. Opened another and it doesn't show either. I tried both starting from an xterm within Xephyr and from an outside terminal (with a DISPLAY env set to :100). No errors, just black screen.

[redhog]

Black screen is expected in this mode: The renderer doesn't have any desktop setup properties to tell it what to render.

[redhog]

Next step would be to run glass-theme before the renderer from the terminal. That should give you some graphics... hopefully.

[IanTrudel]

Running glass-theme results in:

    raise KeyError("Window %s has no property %s" % (self.__window__(), name))

[redhog]

Ah, that's because glass-animator isn't running, which is ok. You can set the mode to no_splash in your theme.yaml see if that works...

[IanTrudel]

And... we have progress! What are the artifacts? Doesn't seem quite right.

[redhog]

That looks distinctly wrong. Never seen! What version of Xephyr etc are you running? I'd like to try to reproduce this!

[IanTrudel]

That looks distinctly wrong. Never seen! What version of Xephyr etc are you running? I'd like to try to reproduce this!

xorg-server-xephyr 21.1.4-1 (xorg)

[IanTrudel]

I tried several applications and a couple of games on Xephyr just to make sure. Seems to be working fine otherwise.

[redhog]

The original problem seem to be some X server / xinit issue, not really directly InfiniteGlass related, see https://forums.linuxmint.com/viewtopic.php?t=254651

The following reproduces the error:

redhog@glittertind:~$ startx -- /usr/bin/Xephyr :100

xinit: XFree86_VT property unexpectedly has 0 items instead of 1
xinit: connection to X server lost

waiting for X server to shut down 
Couldn't get a file descriptor referring to the console
redhog@glittertind:~$ 

(note: no InfiniteGlass involved).

[IanTrudel]

Reproduced the test above:

startx -- /usr/bin/Xephyr :100

xinit: XFree86_VT property unexpectedly has 0 items instead of 1
/etc/X11/xinit/xinitrc: ligne 51: twm : commande introuvable
/etc/X11/xinit/xinitrc: ligne 52: xclock : commande introuvable

Installed the missing twm and xclock packages:

startx -- /usr/bin/Xephyr :100

[redhog]

So maybe that's not the real error, and it kinda works anyway, and then something else breaks?
