GDM Autologin not working..

[krishna.988]

Hi All,

I removed lightdm since I was not able to login as it was booting to a blank screen. Hence I installed GDM and everything was fine. Now when I try to use the Autologin option through GUI interface and also by editing the

/etc/gdm/custom.conf

AutomaticLoginEnable=true
AutomaticLogin= <My User name>

Autologin fails in GDM also. It goes into a black screen.


Can anyone help me out on how to reset lightdm to ubuntu defaults..and autologin?

Btw I tried

sudo dpkg-reconfigure lightdm etc...commands

Do I need to reinstall ubuntu for Autologin to work again?

Should I post in any other section? Why no one is replying?

Nevermind..I reinstalled Ubuntu it was fine..But later on I realized this might be the reason..which might help others facing the same issue

Although normal software updates will bring your system up to 12.04.3, the Hardware Enablement Stack (HWE; the *-lts-raring packages) is not part of those updates (by policy).
You can install the HWE packages manually, but there are some caveats.
To upgrade use this command line only:
sudo apt-get install --install-recommends xserver-xorg-lts-raring
The --install-recommends is important: it makes sure that the xserver will install completely. Without it, xserver will only install partly, and apt will remove most of your system. You do not need to add linux-generic-lts-raring, as it is already recommended by the xserver package, and the 3.8 kernel will install too.
When you upgrade like this you may notice that there are configurations left over, among others those of the original xserver-xorg. You can purge them (I always do), but beware: this will remove the symlink /etc/X11/X that is used to start the XServer, so on next boot it won't start. To prevent this, after purging left over configurations, do the following before the next boot:
sudo dpkg-reconfigure xserver-xorg-lts-raring
This will recreate the necessary symlink and everything is fine again.
