I installed 11.10 ~two weeks ago and run into some strange troubles recently.
Installation was on brand new laptop with clear 160GB SSD. I opted for encrypting home directory. Apart from that I accepted defaults during the installation. There is no other OS on my laptop.
I had circa 40GB in use when (for the third time) I got to see this very unpleasant window:
Twice situation was pretty bad and whole system slowed down considerably. After reboot I could not login to graphical interface (with an error message informing about insufficient space) and had to remove some files from command line first.
Third time I still managed to quickly delete some files and it helped.
My laptop is mainly work environment: so no torrents, games, just two movies. Only media filling space are ~20GB of pictures, and bunch of pdfs. Working mostly on PostgreSQL & PostGIS, GeoServer and QGIS recently.
Although I had lots of opportunities to test and practice my backups I would be extremely grateful if somebody could point me to any potential solutions to this problem.
My laptop has been bought just before I installed Ubuntu, and it came without OS. Could that be hardware issue?
Or is the encrypted
home causing me headaches?
Thanks for help!

Yet another window with low memory message :/
Working recently mostly on VirtualBox and using Remmina.
Following this information I deleted virtually everything from my home directory. Rebooted. There was ~20GB in use after that [~10GB for VirtualBox disk image which I wanted to keep if possible]. Following SarveshLad comment I was trying to recover more space and running Bleachbit application when I got another error of low space on HD. Then the system froze. How on earth can my Ubuntu fill up HD with over 100GB within minutes?
