Bug#489141: xserver-xorg: X server sometimes refuses local xclients to connect
Hi Michael, Michael Hanke michael.ha...@gmail.com (09/02/2009): Yes, it still happens -- less frequently then before, but since the whole thing seems to have some random element I would not put any weight on that observation. still happening with squeeze or higher? Is your $HOME on a particular (e.g. network-based) filesystem? KiBi. signature.asc Description: Digital signature

Unfortunately, I won't have physical access to the machines that showed that behavior for the next months and I don't think they have been upgraded to squeeze yet.

I did still happen last week, but I will check again today. In the meantime I investigated whether clock differences caused this behavior, but syncronizing server and client with NTP did not help.

Bug#489141: xserver-xorg: X server sometimes refuses local xclients to connect
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-server1:1.1.2-6lenny1 /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: [EMAIL PROTECTED]:~$ xclock No protocol specified Error: Can't open display: :0.0 [EMAIL PROTECTED]:~$ xauth list :0 calvin/unix:0 MIT-MAGIC-COOKIE-1 8acb0bbe4feaeb354a32d9c0ea683f8a [EMAIL PROTECTED]:~$ xclock (works) Raoul -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Bug#489141: xserver-xorg: X server sometimes refuses local xclients to connect
Hi, I want to confirm that I'm experiencing the same problem after a fresh lenny install: Occasionally, for an interval of about a minute the xserver seems to block new connections. X applications started during this time return messages like $ xterm No protocol specified xterm Xt error: Can't open display: :0.0 The same for iceweasel, xcalc etc. Michael noted that accessing .Xauthority (rather, the home directory) with ls solves the problem immediately. Might some NFS-related delays be part of the problem? At least in my case the home directory is on an nfs-mount. Gernot P.S.: I'm not sure which information might be helpful. xserver-xorg 1:7.3+18 xserver-xorg-core2:1.4.2-7 xserver-xorg-video-intel 2:2.3.2-2+lenny4 nfs-common 1:1.1.2-6 nfs-kernel-server1:1.1.2-6 NFS-server: nfs-common1.0.10-6+etch.1 nfs-kernel-server 1.0.10-6+etch.1 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Bug#489141: xserver-xorg: X server sometimes refuses local xclients to connect
Hi, I'm still seeing this behavior occasionally. But recently I'm made another observation. During the time when no X clients can cannot I see this: [EMAIL PROTECTED]:~$ xauth list :0 xauth: /home/hanke/.Xauthority not writable, changes will be ignored balin/unix:0 MIT-MAGIC-COOKIE-1 18f7c5d44dfa751698177b1e48daab42 When looking at the permission, I have: [EMAIL PROTECTED]:~$ ll .Xauthority -rw--- 1 hanke users 2,4K 21. Aug 10:52 .Xauthority but now, the next call to xauth looks _always_ (n=10 so far) like this: [EMAIL PROTECTED]:~$ xauth list :0 balin/unix:0 MIT-MAGIC-COOKIE-1 18f7c5d44dfa751698177b1e48daab42 and after that the problem is _always_ fixed, ie. client can connect again. The timing seems to be irrelevant, as soon as I do this, no matter how quick or slow after I discovered the problem, it is fixed.

Bug#489141: xserver-xorg: X server sometimes refuses local xclients to connect
Package: xserver-xorg Version: 1:7.3+10 Severity: normal Hi, first I have to say that I am not sure if this is the appropriate place to report this bug. However, I have no clue what causes it, which makes it difficult for me to convince myself that it was not reported elsewhere or what place would be more appropriate. So, I'd be glad if you could forward this any other/better place. Thanks. Since a few weeks I'm experiencing the situation that from time to time local X clients cannot connect to the local X server: [EMAIL PROTECTED]:~$ xcalc No protocol specified Error: Can't open display: :0 While at the same time foreign clients (via SSH connection) can connect without problems: [EMAIL PROTECTED]:/media/local2/working/hanke/catface2$ xcalc Warning: Cannot convert string calculator to type Pixmap Warning: Cannot convert string gray3?foreground=gray70background=gray85 to type Pixmap This appears to happen randomly and this situation resolves itself after a few minutes. I first discovered this issue on a machine at work which is running lenny (from which I am filing this report). But recently it also started to happen on my laptop and my home desktop machine. While I cannot determine the exact time where the problem started on the 'work' machine (which I update almost daily) I was able to track it down to a single APT upgrade on my desktop machine. Unfortunately, (as I do not upgrade it that often) it involves almost 700 packages, so I'm not sure whether this really adds useful information. But I can nevertheless provide it, if helpful. I also tried looking whether the xauth would provide something helpful, but this output looks identical in both cases: [EMAIL PROTECTED]:~$ xauth list balin:0 MIT-MAGIC-COOKIE-1 1bacbd81d88b69b5d089c69454cac1a6 [fe80::219:99ff:fe2b:e81c]:0 MIT-MAGIC-COOKIE-1 1bacbd81d88b69b5d089c69454cac1a6 balin/unix:0 MIT-MAGIC-COOKIE-1 1bacbd81d88b69b5d089c69454cac1a6 Help is very much appreciated.
