Wow, my system crashes hard - right after login! I've heard about quite some crashed with Ubuntu 12.04. ... any suggestions on how to proceed?

Here is the link to the logfile of Boot-Repair - which I tried without success (details see below):

http://paste.ubuntu.com/1630291/

Also, running memtest86 from the boot-up program resulted in 0 errors found. Neither, did a check on the harddrives yield an error message.

Further Details

Ubuntu will boot fine up to the login screen. Then - after I enter the password and hit login - it will hang. I am not able to enter anything at the resulting screen (see image - larger view here).

Screen after crashing

The first time this occurred was right after I cleaned my computer carefully with aerosol. Maybe a hardware damage? But I don't think so, it was minimal maintenance mostly focusing on the cooling-fans. Also, I removed an old harddisk (no boot partition, just mp3 data).

Regarding Boot-Repair ... ran it through UbuntuSecureRemix (a Ubuntu boot mix CD) a and used the standard option "Recommendend repair - repairs most frequent problems".

You can reach the login screen, so the problem is located after the bootloader (GRUB). SO Boot-Repair can't help. I would bet you have a memory (RAM) problem. Try checking it. –  LovinBuntu Feb 10 '13 at 22:35
    
Ran memtest86 from the boot-up program and it reported 0 errors after 2 passes. From what I've read none of the memory modules should be faulty/replaced in this case? Any further suggestions? –  somethis Feb 11 '13 at 0:35
    
Just got through checking the harddrives ... no errors reported either. Rebooted the system to the same ... crash! :( –  somethis Feb 11 '13 at 0:51

Ok, got back into my system and it is running.

To help others, here is the simple fix:

All I had to do is boot into an older kernel! :) (here is an explanation on how to do it http://askubuntu.com/questions/97731...keeps-crashing )

Note though, that I had to go back to a kernel as low as 2.6.x. I won't reinstall for now - there are too many issues reported with 12.04. or 12.10. - but if I notice unusual behavior I will. Now, is a good time to run another backup on /home.

glad you found a workaround. I strongly recommend you create a bug report (via the ubuntu-bug linux command), so that developers can fix the bug in next Ubuntu releases. –  LovinBuntu Feb 14 '13 at 16:08
    
this is fun ... ubuntu-bug linux responded with "Problem in linux-image-2.6.32-45-generic ... The problem cannot be reported: This is not an official Ubuntu package. Please remove any third party package and try again." –  somethis Feb 14 '13 at 18:03
    
ok. Then report the bug directly here: bugs.launchpad.net/ubuntu/+source/linux/+filebug –  LovinBuntu Feb 17 '13 at 22:20
