not affected earlier. Maybe a reinstall might fix this issue? Two out of
three reboots lead to failsafe X. Sleep command improved the

On 14.04, with an Intel graphics card, installing GDM (and choosing
that as the default) instead of Lightdm worked for me. All of the
suggestions with 'sleep' or 'lightdm service restart' were useless for
me.

If I enter the password for my account then the black screen is displayed I am

This has just started happening today on my 13.04 64-bit install .
Yesterday updates to 3.8.0-19 were installed, don't know if that's just
a coincidence.
Have added sleep 2 as per comment #16, still got the issue.
This install is only about 1 week old, and was done from fresh (not an
upgrade).
Just wanted to mention that I ordered a new 512GB Samsung 840 Pro SSD,
for my ThinkPad X220, in anticipation of installing 13.04 from scratch.
And I can confirm what everyone else is saying.
The reboot after the installation hung. I powered down and powered it up
again, and it hung at a black
I'm experiencing this bug on every other boot since a few months now. At
first, I was using 12.10 but last week I updated to 13.04 and the issue
remains;

- a movable mouse cursor becomes visible in the center of the screen

I came across another fix, when changing the greeter stopped working.
For those who removed Unity, removing it sometimes uninstalls unity-

fixed my low resolution issue.

This has also hit me on fresh 12.10 AMD64 install with a Thinkpad T530

But it only started after the last kernel update (3.5.0-26.42). Before
then it was working fine.
The listed workaround of restarting lightdm also works for me.

Just add a comment here that I have a new fast PC + SSD + HD4000

12.10. I solved the low graphics mode issue long ago by changing from
lightdm to gdm. I have 2 screens and occasionally I boot up and get 1

I get this problem frequently following a restart from 12.04.

Same problem on two systems (one with Intel and one with radeon) both

The problem seems to be a race condition where the system boots so fast
that the graphical stack is not ready for lightdm to work.

I have the same issue with a fresh update to the 13.04 (Raring Ringtail)
alpha 2 from 2013-02-20.
It obviously affects the next version with the 3.8.0 kernel as well.
After I inserted a sleep 1 line in /etc/init/lightdm.conf after line
36 (as the first line of the main script code), the problem
I think I see the problem on an X230 with Intel graphics and a SSD. Does
black screen mean text login screen? I get that more often than the low

When I get the text login and look at the Xorg log I see the X server failed to
start with the following error:
