Gracias por responder, madpitbull_99 :
El directorio donde tengo configurado xampp es: /opt/lampp/
Aquí entro como root y encuentro estas carpetas:
bin
cgi bin
error
etc
htdocs
icons
libs
libexec
licenses
log
modules
phpmyadmin
sbin
share
tmp
var
Pero he "bicheado" por ellas y no encuentro .htaccess
El manual lo saqué de aquí
http://robersoft.blogcindario.com/2011/09/00022-instalar-xampp-servidor-web-en-linux.html, donde asegura que el usuario por defecto es lampp, aunque a mí no me funciona.
No sé si puede ser un problema con la base de datos, pues al reiniciar xampp me sale esto:
Starting XAMPP for Linux 1.7.7...
XAMPP: Starting Apache...
XAMPP: Starting MySQL...
[b]XAMPP: Couldn't start MySQL![/b]
XAMPP: Starting ProFTPD...
XAMPP for Linux started.
En los logs no he encontrado nada.Los pego por si acaso:
