Light DM issues

[statmonkey]

I hadn't rebooted for a while ... oh lets say a couple of months and when I did lightdm seems to be failing google gives me some bug reports but no answers.  I can start x with no issues logging in and running startx but I see the same issues in my logs and running lightdm in test mode repeats the same error:

*** Error in `lightdm': double free or corruption (fasttop): 0x00007f6f371e8ab0

Has anyone else seen this or does anyone have a hint to a solution?

Thanks

Aye.. Suffered through a power outage last night and when I turned the machine back on I am getting the same exact thing. I noticed an update to LightDM yesterday and I am sure this is the issue.  For the record, please explain how you are restarting X so that others may learn from this

Me too, I think it has something to do with systemd....
It booted fine yesterday before I updated, I'm pretty sure I saw both lightdm and systemd update...

Code: [Select]

$ systemctl status lightdm.service

Edit: As a workaround I installed xinit and added "exec startfluxbox" to my ~/.xinitrc.  It didn't autoload my .Xresources though...

[PackRat]

Yes, both systemd and lightdm have had recent upgrade(s). I haven't had any issues with lightdm though.

@orbea add xrdb to your .xinitrc file. Something like -

Code: [Select]

xrdb -l ~/.Xresources &
that's pretty basic, and the default for xrdb, I think. Man page has a lot of other options.

Not really much to it.  When the system quit complaining about lightdm it gave me a login prompt.  Logged in as my user and ran startx.  Of course that caused other issues so it's not ideal.

I have done a little research and noticed that things for lightdm are completely different.  For example lightdm-set-defaults is completely gone and things have been moved around.  Of course I would suspect that lightdm which is horribly documented and is pretty much made for F_ubuntu is probably looking for some upstart conditions.  I am speculating here but ... grrr. Will look further.

I appear to be completely lost... I am not able to even start startx

I booted to this partition which is the last Build partition before 3.16 (something I always do is change to the latest kernel on a totally new build partition)

Did a search and found no startx on this partition or on the new one (3.16) either

What am I missing?  (It has been a very very long trying day)

If this is the first bomb of systemd shutting out something as critical as the DM, then it sets a bit of panic down my spine...

[orbea]

Did you install the xinit package?  I was surprised when I noticed vsido didn'thave xinit by default which has startx.

[VastOne]

No and xinit is not necessary (nor is starx) to successfully boot to X..  and is not a part of VSIDO by design

I recall using startx in the past from another package though... it also seems to me that smxi also depends on startx .. I will research more and find it in the hallows of my fading memories

I recall using startx in the past from another package though... it also seems to me that smxi also depends on startx .. I will research more and find it in the hallows of my fading memories

Out of curiosity, what other ways are there to boot to X without xinit or a display manager?  I looked at packages.debian.org, but the only package I can find with startx is xinit, I'm wondering what you are recalling now too.

[VastOne]

LightDM is that DM and with it broken then so goes the boot

Still racking my brain but am more concerned with the fix to lightDM or systemd

[statmonkey]

I can't imagine that startx would be removed.  That is curious.  Just checked again and I have no issues using startx.  Still no idea what they have done to lightdm and why it is failing but clearly it's structure has changed.

Just an update.  If I run startx - get into an xsession and then run my lightdm default.sh as a user it runs with no errors and it seems I am in a lightdm session.  Soooooooooo I would speculate that during boot lightdm is calling for a file that isn't there and defaulting to failure.  More as it unfolds.

[VastOne]

Xinit is not installed and therefor startx is also not a part of VSIDO... I have used startx in the past most likely trying to resolve nVidia issues.  Having gone to lightDM and pure nouveau as my drivers I do not miss xinit or startx

For clarity, I am on the build server partition now that had been my main build all through kernel 3.14 and 3.15.  It does not have xinit and startx either and until today it has not been used or useful

I am working now on changing the lightdm-gtk-greeter.conf around to see if that makes a difference

Not sure if it's related but my system is really lagging. In fact unusable typing this on my phone. I noticed in the service.lightdm file a comment about only using this structure until the dms catch up and that it is starting lightdm directly and ignoring all configuration files. That explains a lot. I also saw my logs filled with errors. I am pretty anal about keeping it clean so something has changed more than lightdm on my system at least.

I switched to xdm and got to a login screen with no issues.  System is still laggy for example can't use terminal at all.  I am not sure what is going on this may just be a sid issue but I have not seen any warnings on upgrade and don't see anything on googling. Hmm. Strange times.

OK, since 15 minutes ago, (last post, which was right after a dist-upgrade), I've lost 'spacefm'  from the menu or the terminal.  Due to IG's decision to go on hiatus, this is a bummer.  I really love spacefm!  Not the end of the world however.
I also am not having any of the issues you guys are having.  One thing of note;  I'm using the Liquorix Kernel 3.16-2.dmz.1-liquorix-amd64.
My lightDM screen definitely looks different, but works great.  No java related issues either.  (or icedtea)  The errors from terminal with spacefm are making me think GTK related...
I'll keep looking...
