Bug#489141: xserver-xorg: X server sometimes refuses local xclients to connect

[Raoul Borenius <raoul@shuttle.de>]

Hi,

I'm seeing the same problem since my upgrade to lenny, /home is an
NFS-mount.

In my case the problem does not disappear by itself but I always need
to do run 'mount -o remount,rw /home' on the NFS-client which solves
the problem for some time.

Both client and server are up-to-date lenny-systems:

client:

nfs-common                                   1:1.1.2-6lenny1

server:

nfs-common                                   1:1.1.2-6lenny1
nfs-kernel-server                            1:1.1.2-6lenny1

/etc/exports:

/home           calvin(rw,async,no_root_squash,no_subtree_check)

/etc/fstab:

gw:/home         /home       nfs     rsize=32768,wsize=32768,intr 0 0

This configuration did work without any problems for several years
up to and including 'etch'.

If there's anything I can do to narrow down the problem I'll be happy
to do it.

P.S.: running 'xauth list :0' instead of 'mount -o remount,rw /home'
as suggested by Michael Hanke does also solve the problem in my case:

raoul@calvin:~$ xclock
No protocol specified
Error: Can't open display: :0.0
raoul@calvin:~$ xauth list :0
calvin/unix:0  MIT-MAGIC-COOKIE-1  8acb0bbe4feaeb354a32d9c0ea683f8a
raoul@calvin:~$ xclock
 (works)
