A million bugs after updates. Can not login

You're welcome. And, welcome to Kubuntu Forums . Net!

Because you are on an 'older' Kubuntu release, let's look to see if you have any of the removed kernel's header packages still installed and remove them if they exist. In the console type:

sudo apt-get purge linux-headers-3.0.0-12-generic

Repeat for the following:

3.0.0-16-generic
3.2.0-24-generic
3.2.0-25-generic
3.2.0-26-generic
3.2.0-27-generic
3.2.0-29-generic
3.2.0-30-generic
3.2.0-31-generic
3.2.0-32-generic
3.2.0-33-generic
3.2.0-34-generic
3.2.0-35-generic
3.2.0-36-generic
3.2.0-37-generic
3.2.0-38-generic
3.2.0-39-generic
3.2.0-40-generic
3.2.0-41-generic
3.2.0-43-generic
3.2.0-44-generic
3.2.0-45-generic
3.2.0-48-generic
3.2.0-49-generic
3.2.0-51-generic
3.2.0-52-generic
3.2.0-53-generic

I tried but it doesnt look like

bender@oneiric-vaio:/home/work/Notes/QuadraticNonlinearity$ sudo apt-get purge linux-headers-3.0.0-12-generic
[sudo] password for bender:

Go ahead and do it for the others "just to be sure", unless you already have.

81% in use for your root partition (/dev/sda5) seems still 'high' as far as I'm concerned, especially if you only have the two kernels (now) installed and the package cache has been cleaned up.

Ok I did it for others - few of them were in a system
Now I have

bender@oneiric-vaio:/home/work/Notes/QuadraticNonlinearity$ df -hT --exclude-type=tmpfs --exclude-type=devtmpfs
Filesystem     Type  Size  Used Avail Use% Mounted on
/dev/sda5      ext4   23G   18G  4.6G  80% /

/dev/sda9      ext4  179G   85G   86G  50% /home/media
/dev/sda8      ext4   74G   27G   43G  39% /home/work
bender@oneiric-vaio:/home/work/Notes/QuadraticNonlinearity$ dpkg --list | awk '/linux-image/ {print $2}'
linux-image-3.2.0-53-generic
linux-image-3.2.0-54-generic
linux-image-3.2.0-55-generic
linux-image-generic

Also after all of this updates the graphics environment changed very strongly and few minor things are displaying a little bit incorrectly (like popping menu in let say second monitor window) or things a overlap with each other in K menu - is there any way to check that graphics environment works correctly? I mean as for right now i figured out just a couple minor things but maybe there is a way to check that everything with graphics is correct?

My advise, as to what we have just finished going through, is to keep only two kernels installed: the latest one and the one prior. In your case, keep 3.2.0-55-generic (which you are booted into) and 3.2.0-54-generic (as a 'life boat'). Go ahead and remove linux-image-3.2.0-53-generic. Then, when that is done, type:

sudo update-grub2

This thread can now be closed, as the initial 'major' issue has been solved.

Please open separate threads for your other questions. As you are using 3.2.0-55 (Precise), please open the new threads in that sub-forum.

Ok I did. Thank you @vinnywright and @Snowhog again.
