Wanted to decrease the sensitivity of my touchpad and have the setting remain after boot up. Follow this suggestion (caveat: I added two "Options" lines for Finger sensitivity and noise cancellation), I made an xorg.conf file.
Now on boot up, I arrive at a black screen with a cursor that is not blinking. I briefly see the Xubuntu start page before it goes black, but then nothing.
For reference, I'm dual booting Xubuntu 14.04 and Windows 10 on a Dell Inspiron 1550.
sudo reboot
from the console. – WinEunuuchs2Unix Sep 19 '16 at 10:17
