Failed to log in while xorg.conf exists in /etc/X11
 

Hi all!
Yesterday I have upgraded my Asus U50V from Debian 8 to Debian 9 and found inoperative touchpad ElanTech ETPS/2.
Trying to solve that I have copied /usr/share/X11/xorg.conf.d/70-synaptics.conf to /etc/X11/xorg.conf with copy-pasted output of synclient (afer restoring touchpad operation) and met another problem.

Now after rebooting I'm unable to login in graphic shell (GNOME) - it falls in endless loop prompting me to enter password again and again. The same happens with using "not in list" button.
That can be avoided by loging in from another virtual terminal (Ctrl-Alt-F2) and renaming /etc/X11/xorg.conf. Then Ctrl-Alt-F1 - and normal login is available.

So, three questions in one :-) : can I easy have by default
1) left-handed mouse (well, there are a lot of posts on that, I didn't try yet) 2) with operative touchpad and
3) possibility to login without terminal switching :-),
like it was two days ago under Debian 8?
Thank you!
Vladislav.

sorry for my harsh critique, but that is complete nonsense.
just delete that file and reboot.
does Xorg now start again?

while it is possible to fix a non-operative touchpad through Xorg config files, it can also be fixed with configuration after login.

let's see the oputput of these terminal commands:

Yes, that is the way how it works now. String
is added to ~/.profile

Maybe my xorg.conf is wrong? I have inside:

Sorry, I am newbie here, I don't know how to roll up such long pastes.

Thank you!
Vladislav.

so it works like this?
then copy /usr/share/X11/xorg.conf.d/70-synaptics.conf to /etc/X11/xorg.conf.d/70-synaptics.conf, and add those options to it (the syntax might differ slightly, check that beforehand).

ondoho thank you! (Really thank you!) You have given me two hours of fascinating investigation. The result is: suggested /usr/share/X11/xorg.conf.d/70-synaptics.conf can work (I mean do nothing) only in it's original untouched state in both /etc/X11/xorg.conf.d/70-synaptics.conf and /etc/X11/xorg.conf places. Any added string like in code below results in endless login.

At least I have understood that it is far beyond of my knowledge of Debian.

Thank you!
Vladislav.

A lot of thanks to everybody. I have got it. xorg.conf does not accept raw output of synclient. It should be instead of Now everything works. I'm marking this thread as "Solved".
