Hello everyone, this is my first post on a thread ever. Usually I have always been able to fix my issues myself, but this one really has me stumped. So I'm on a late 2011 27 inch iMac. I dual boot Mac OS el capitan and Kali 2.0. I have been using kali for quite a while now, with no issues.
Yesterday however, I was working on a C project, using CLion, and after I built the project, and the executable file was saved, the system began to be really slow and laggy. A little while after I tried figuring out what had happened and why everything was so slow, a message came up telling me that my filesystem root has 0 bytes of space left.
The system was running so slow, that it was just painful to use, so I figured I'd reboot and just use terminal to clean up some files and free up space. I rebooted the machine, but decided to see if I log back in, how slow my computer would be and whether it was just a fluke.
However, I could now not get past a certain point during the startup messages letting me know all services are starting up ok. It hangs on after the ok message for started update utmp about system runlevel changes. I tried pressing alt + f2 to log in just using terminal, and found that it's actually putting out loads of gnome-shell messages about int3 errors.
After a while, it stops, and I can log in into terminal, but that's it, it doesn't graphically boot. I deleted some files and some old gz log files that were taking up space, freed about 5 GBs, but the df command still lists my root installation dev/sda4 as 100% used. Freeing up the space didn't do anything, I still get the same error. I can provide any more information if required, I just want to get this fixed ASAP. Thank you all for your patience and reading through this wall of text.
