Whenever I try to open LibreOffice, Ubuntu stops running and opens the text-y DOS looking screen and restarts light display manager. Every time I open any of the LibreOffice office programs it crashes. I have no idea what is happening, I am a bit new to Ubuntu. Please help.
I had Ubuntu 14.04 for a few weeks, then today when I turned on my PC it prompted me to update to 14.10. After downloading and installing everything, it told me to restart my computer. It turned off and turned back off, but the screen never displayed anything. The computer is on but it won't display, it just says "no signal". What can I do to fix this?
I want to reset Ubuntu. I have searched it on Google many times and I am new to Ubuntu so I am wondering how to reset it without too much complication. I have already tried re-installing it but my computer will not boot from the DVD. I am using Ubuntu 14.04.2 LTS.
I want to completely delete everything and have it start like it did when it was originally installed. Completely erase everything and restart, reinstall, and reconfigure Ubuntu.
