Lubuntu : session won't open : where to find the logs
I finally fixed it.
I found some post on the internet that recommended to have a look at: ~/.cache/lxsession/Lubuntu/run.log
which contained some nasty error messages but started with this:
** Message: utils.vala:85: System system path location : ~/.config/lxsession/Lubuntu/desktop.conf
** Message: utils.vala:89: Final file used : ~/.config/lxsession/Lubuntu/desktop.conf
and on the previous day, I had been changing config in lxsession-default-apps which writes things in this exact same file: ~/.config/lxsession/Lubuntu/desktop.conf
So I moved this file somewhere else, and the next startup worked. A new ~/.config/lxsession/Lubuntu/desktop.conf
was generated and I am good to go.
Though it is really bad that things crash this way just by changing settings into a lxde program... But I don't know exactly what was the source of the problem so I can't really make a bug report.
Thanks for support!

I have a huge problem here.
As I turn on my laptop, I reach the session login splash screen. I select my user name, but straight after my desktop is loaded, a really quick message appears (too quick to read it) and I'm logged out...
I guess something is wrong in a script that should be loaded on startup, but I don't know how to debug that...
Where can I find the logs of session opening?
I tried
script filename
to register in another console, but that did not work, I tried to edit ~/.config/lxsession/Lubuntu/desktop.conf but without success either.Any advice will be appreciated! Thanks
I'm using Lubuntu 13.10
EDITThanks @Ash for reply. Here my
/var/logs/Xorg.0.log
file extract, looks like an error there:(EE) BUG: triggered 'if (priv->num_active_touches == 0)' (EE) BUG: ../../src/synaptics.c:2658 in UpdateTouchState() (EE) (EE) Backtrace: (EE) 0: /usr/bin/X (xorg_backtrace+0x3d) [0x7f5ced093fdd] (EE) 1: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f5ce4524000+0x2c74) [0x7f5ce4526c74] (EE) 2: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f5ce4524000+0x4b40) [0x7f5ce4528b40] (EE) 3: /usr/lib/xorg/modules/input/synaptics_drv.so (0x7f5ce4524000+0x6752) [0x7f5ce452a752] (EE) 4: /usr/bin/X (0x7f5cecef1000+0x91ee8) [0x7f5cecf82ee8] (EE) 5: /usr/bin/X (0x7f5cecef1000+0xba930) [0x7f5cecfab930] (EE) 6: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7f5cebff1000+0xfbb0) [0x7f5cec000bb0] (EE) 7: /lib/x86_64-linux-gnu/libc.so.6 (__select+0x33) [0x7f5ceacfdde3] (EE) 8: /usr/bin/X (WaitForSomething+0x19c) [0x7f5ced09159c] (EE) 9: /usr/bin/X (0x7f5cecef1000+0x54fb1) [0x7f5cecf45fb1] (EE) 10: /usr/bin/X (0x7f5cecef1000+0x447ba) [0x7f5cecf357ba] (EE) 11: /lib/x86_64-linux-gnu/libc.so.6 (__libc_start_main+0xf5) [0x7f5ceac2cde5] (EE) 12: /usr/bin/X (0x7f5cecef1000+0x44aff) [0x7f5cecf35aff] (EE)
I googled this error, and I don't have the feeling it's related to the problem I have though...

Ash over 9 yearsSo you can get to a terminal okay? Can you check
/var/log/Xorg.0.log
and see if there is anything that looks like an error? -
Augustin Riedinger over 9 yearsUpdated my question with log extract.

Ash over 9 yearsHmm, it doesn't look like a happy log, but as you say I'm not sure it's related or how to go about fixing it. There is a question with similar symptoms (askubuntu.com/questions/223501/…) but it's Ubuntu, not Lubuntu, so not sure if any of the suggested answers apply. Not sure what things you could try sorry, hopefully someone else can suggest something!
