[Bug 47145] It's not possible to login through GUI when disk is full

[mnemo]

Public bug reported:


Currently when I try to login (through the X GUI normal ubuntu login screen) I get a message saying some auth file can't be written and then I'm returned to the login prompt. My / partition is full and I know this, but how can I login to fix it if ubuntu refuses me to login? This is "moment 22" kind of.

(as it turns out I could CTRL-ALT-Fx my way into a CLI mode terminal and
delete some files but most users cannot do this and really, this is not
something that we can expect from the average ubuntu user).

Last year, I ran into this exact problem on my schools Redhat systems
too... all in all, this is one of those bugs that people run into every
now and then and it generally causes a lot of problems for people. And
it would be pretty easy to fix it...

** Affects: gdm (Ubuntu)
     Importance: High
         Status: Confirmed
