Comment 38 for bug 115774

Kubuntu 14.04 still hangs on boot when the disk is full.

My disk was full and the result was that after the normal login the system simply hangs. After switching to the console and removing some files I could restart and login.

I think, that if the disk is full, kubuntu should popup with a message and (more important) switch to the console. And should create a warning if the disk space is getting low.
