HELP! Cannot use mouse or keyboard any more

[Kevin O'Gorman]

I'm running Xubuntu, and have done for quite a while.  Right now it's at
14.04.   I just hosed it somehow, and when I reboot I cannot log in because
the keyboard and mouse are being ignored.

It's not the hardware, because the grub menu works with the keyboard, and
going to a recovery version of the kernel also works but it's console mode,
not X.  But when I try a normal boot, the cursor stays in the middle of the
desktop and the keyboard cannot enter my password.  I have to do a hard
reset because 3-finger salute is also ignored.

The last thing I did was to change my nVidia settings by deleting one of my
monitors.  That means X configuration, which also affects mouse and
keyboard.  But I cannot find an xorg.conf file anywhere.

Probably I just need to find out where the config settings are kept, and I
can reset them from a backup.  Does anybody know?
