Re: [Ltib] How to start X.

[Stuart Hughes]

Hi Kevin,

The ISP I use to host the GPP (and bitshrine/ltib.org) is just a
bog-standard (that's an English expression) account.  They're pretty
good, but I think from time to time there are outages.  Also wget has a
timeout (adjustable), which will bomb out if the remote URL takes to
long to reply.

Regards, Stuart
