Dear Maintainer,

In previous versions of debian, If you crashed the X server, or just wanted a quick shell as an other user, It is a simple
matter to switch virtual terminals, and get back to work. but lightdm adds the -novtswitch option to the X server to disable
this functionality. the patch bellow would alleviate the immediate symptoms, but another configuration option would be
better.

What “functionality”? The novtswitch is just for user experience, as far
as I understand it, you can still vt switch perfectly fine.

Dear Maintainer,

Some time ago i noticed, that i can not switch between VT, but thought it
was related with mutiseat experiments. But, now i have a new Debian
installation, and my integrated videocard is disabled in BIOS. And I still
can not switch in TTY[1-6], it just crashes my DE and brings me bach lo
lightdm-greeter.

Sometimes it shows me terminal, but can not catch it now to see the logs.
Will attach one, if possible.

Best regards, Dmitrii

Can you try with a different DE?

I think it'd help having ssh access to the box to debug that, to see
exactly what crash (Xorg, the session, something else...)

Yes, i tried both e17 and xfce, and it is no difference. I even can not use
tty when lightdm-greeter is on my screen, only "service lightdm stop", as a
workaround in use now.

About ssh - where must i send authentication data, to avoid publicity? (I
hope it is configured properly)


Best regards, Dmitrii

That looks more related to an issue with X than with lightdm, actually.

I wasn't asking for an ssh access *for me*. I was asking you to use ssh
from another box of you so you can properly debug X issues yourself.

Hi,


the hardcoded command line option breaks usage of alternate X servers.

E.g. when using Xephyr as xserver command for multiseat setups.

This should really be fixed.

I've implemented a configuration variable,
"xserver-allow-vt-switch", which inhibits the hard-coded
"-novtswitch" flag.

I've emailed the patches to the maintainer and have pushed the
changes to the "vtswitch" branch here:

I hope this helps others.  I'm on sid and this is still an
issue, so I figured I should try and fix it...

cheers,
