Startx error

[zen3GR]

I tried to get x server up and running by giving startx after i logged in but nothing happened. I have to note two things:
a)it's a new problem, yesterday i had x running normally
b)i searched the last 2 lines of the log i give below but couldn't solve it (i tried this solution only [http://www.jaredlog.com/?p=115] because the most of threads i "met" was about freebsd).

startx output:

hostname: Name or service not known
xauth: (argv):1:  bad display name "laptop:0" in "list" command
xauth: (stdin):1:  bad display name "laptop:0" in "add" command

Thanks for having developed such a beloved and supporting community and for your time.

Please, would you post the content of:
1. /etc/hosts
2. /etc/hostname
3. /etc/hosts.allow
4. /etc/hosts.deny

Need to check if localhost and 127.0.1.1 (your hostname) are present or has not been modify...

It sounds to me like your hostname and hosts file don't match up. Can you post:

cat /etc/hostname
cat /etc/hosts

[zen3GR]

Thanks for your time!

1. /etc/hosts

laptop
#::1 localhost localhost.localdomain laptop.localdomain
#127.0.0.1 localhost localhost.localdomain laptop.localdomain

2. /etc/hostname

laptop

3. /etc/hosts.allow

# /etc/hosts.allow: list of hosts that are allowed to access the system.
#                   See the manual pages hosts_access(5) and hosts_options(5).
#
# Example:    ALL: LOCAL @some_netgroup
#             ALL: .foobar.edu EXCEPT terminalserver.foobar.edu
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
#

4. /etc/hosts.deny

# /etc/hosts.deny: list of hosts that are _not_ allowed to access the system.
#                  See the manual pages hosts_access(5) and hosts_options(5).
#
# Example:    ALL: some.host.name, .some.domain
#             ALL EXCEPT in.fingerd: other.host.name, .other.domain
#
# If you're going to protect the portmapper use the name "portmap" for the
# daemon name. Remember that you can only use the keyword "ALL" and IP
# addresses (NOT host or domain names) for the portmapper, as well as for
# rpc.mountd (the NFS mount daemon). See portmap(8) and rpc.mountd(8)
# for further information.
#
# The PARANOID wildcard matches any host whose name does not match its
# address.
#
# You may wish to enable this to ensure any programs that don't
# validate looked up hostnames still leave understandable logs. In past
# versions of Debian this has been the default.
# ALL: PARANOID

I'm getting the same thing with the last two RCs of Backtrack as well. I'm using the RCA out on a ATI video card and getting squat back. DVD Boots, i get a boot: prompt thru trial and error found out hitting enter gets past that (yet same releases in 64 bit didnt need it for the dual core running RC 2), i get the root@bt: prompt, k i know startx goes in there from the 64 bit version and pluhhhh..tv goes blue from no signal, DVD spins a few more times. Thats where it sits. This is the first time ive run the 32 bit versions and they aint dual cores so i cant rung the 64. Is there some Xorg Cheat idea like Puppy has to fool the installer to not use the out of the box desktop settings and force it to the output instead. Ubuntu 10,11,and 12 all pick up that output just fine and im really getting antsy to try the 32 bit RC3. No i dont have a spare monitor and thats half the problem, using tvs here...Any reply would be helpful, I am fairly noobish to this all so bear with me.

You should edit your /etc/hosts file. Try adding this:
127.0.0.1 localhost.localdomain
