login - Low graphics error unless I boot via recovery mode


I recently upgraded to 12.10 (fresh install). I am a facing weird problem:


When I boot, I get a message notifying me of low graphics. For now, I have been switching to console using Alt+F1 and then rebooting.


Upon reboot, I select recovery mode, allow system to boot and then again reboot.


Now I select normal mode and my graphics load smoothly.


Could you please tell me what could be the issue? I have a Dell Inspiron 5230 with Intel 4000 onboard graphics.



It has absolutely nothing to do with the GPU. It's a problem with LightDM and SSDs (or some other "abnormally fast" piece of hardware, Nvidia cards cause the same issue)


Try adding


respawn

below


stop on runlevel

In /etc/init/lightdm.conf


Often times, if you run into this error, you can hit


[Ctrl] + [Alt] + [5] to enter a terminal. Login and try


sudo lightdm start

If that doesn't yield anything try


sudo service lightdm restart

As a side note, my SATAIII SSD was connected to the SATAII port on my logic board when I ran into this issue. Verify that your main SSD is on the correct port before you try anything.
