Hi all.
In reference to these threads
I have the following issue:
I am running a live usb with persistance and got low disc space leading to low graphics mode in reference to this thread How to fix "The system is running in low-graphics mode" error?

When i try to get to a tty with ctrl alt f1 or ctrl alt f1 to f8
In order to execute autoclean cmd
i get
Ignoring BGRT invalid status 0 (expected 1) No caching mode page found Assuming drive cache: write through Permission denied Error @wl_inform single bss frame error
Anyone knowing how to get to a terminal so i can free up some space?

By disabling Wifi I managed slightly to get rid of Error @wl_inform single bss frame error but I still cannot get to a terminal It shows error msg s33.postimg.org/h8ij4f2en/20160526_015953.jpg I followed youtube.com/watch?v=o31QGpjR8KE and it turns out it is NOT a graphics error which is insane per the error message. It is a LOW disc space.

I gather the keyboard layout on the live usb may have been set as wrongly as a default and that is why the combo ctr+alt+f*1-8 is not showing a terminal. I see some suggestions FN could be used to trigger F keys ubuntuforums.org/showthread.php?t=1712424 but not in my case. Any suggestions on how to open a tty to Clean up disk space and start my session???
