Public bug reported:
I'm using Ubuntu 12.04.1 LTS. With the kernel update to version linux-
image-3.2.0-32-generic (ubuntu kernel) the system boots but the display
always turns black instead of displaying the ubuntu splash screen and
stays that way.
Despite all that the system is useable in the sense that I can use it
blindly, so loging into Gnome 3 (non fallback version) etc. works, just
without any graphics. It is also possible to use ALT+F1, blindly start
the network manager and use the system via SSH.
When starting the system in the resue mode and then choose "resume" the
system starts properly (with graphics being displayed), yet without any
graphics acceleration (which leads to Gnome 3 fallback mode).
I've tested the mainline linux versions and it seems that the problem
was introduced between mainline version 3.2.28 (works) and 3.2.29
(fails).
The system is a Dell Latitude E5510 laptop, with an Intel Core i5 M 520
with integrated graphics. I've attached the syslog of a failing start,
yet I don't see any error message being raised. It seems as if the
system does not even know that it does not display anything, even
programs like glxgears, rhythmbox, etc. run perfectly fine.
Thank you for your help, if you need any additional debugging
information please let me know. I unfortunately do currently not have
the time to perform a kernel bisection.
