[Bug 728017] Re: xwindows over ssh causes instability
It sounds like the core of the problem is compiz (your window manager) refusing to draw other windows while it is waiting for firefox to update. Please give the output of: cat /etc/lsb-release and try doing apport-collect 728017 on the laptop again, which hopefully will give us more info about what's going on with compiz. ** Also affects: firefox Importance: Undecided Status: New ** Package changed: openssh (Ubuntu) = compiz (Ubuntu) ** Also affects: openssh (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. https://bugs.launchpad.net/bugs/728017 Title: xwindows over ssh causes instability -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 728017] Re: xwindows over ssh causes instability
I see, I thought you were saying there was instability on the host.
I've just tried to reproduce this ssh'ing from a ubuntu lucid to a
ubuntu natty laptop and running firefox, with no success.
Additional information which would help to debug this:
1. The next time this happens, please do 'apport-collect 728017' which
should give us more details.
2. Can you give me a particular site which always reproduces this?
3. Please do 'wmctrl -m' and 'wmctrl -lG' on the client and give output
here. ('sudo apt-get install wmctrl' if needed to get the program)
4. Please give ps -ef from the client

[Bug 728017] Re: xwindows over ssh causes instability
Sorry, two more questions: 1. is there any other program which can make this happen? Can you run 'xterm' or 'gnome-terminal' or 'xeyes' with no problem? If not, then we should probably mark this bug as affecting firefox as well. 2. exactly what happens on the client when it is misbehaving? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. https://bugs.launchpad.net/bugs/728017 Title: xwindows over ssh causes instability -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 728017] Re: xwindows over ssh causes instability
1. apport-collect 728017 Package openssh not installed and no hook available, ignoring It then says no addition info gathered. 2. Not any particular site, when firefox is open across the network, even when not browsing anything, just moving the window around the screen will cause momentary freezes for the whole gui, client side. Also, keep in mind that I think you need a slow host or connection to the host to replicate this. FF takes over 2 minutes just to launch after typing in the command. 3. $ wmctrl -m Name: compiz Class: N/A PID: N/A Window manager's showing the desktop mode: OFF $ wmctrl -lG 0x04200041 0 758 166 1276 1088 compy Inbox (148 total) - Evolution 0x0163 -1 02352 1920 24 compy Bottom Expanded Edge Panel 0x01600028 0 001920 24 compy Top Expanded Edge Panel 0x0180001e -1 001920 1200 compy x-nautilus-desktop 0x03400084 0 086 1920 1133 compy Bug #728017 in openssh (Ubuntu): “xwindows over ssh causes instability” - Mozilla Firefox (Build 20101206121716) 0x0484 0 1538 658 657 435 compy enb@compy: ~ 0x04a0009d 0 10 94 1328 711 compy *Untitled Document 1 - gedit 4.

[Bug 728017] Re: xwindows over ssh causes instability
Simply interacting with the firefox window, like moving it around or resizing it, seems to cause it to freeze up, and when it does, so does the rest of the gui, including local apps and the taskbar, etc. firefox seems to be the only app over ssh that seems to cause it so far, xeyes and other things don't. Something that might be related, is that when I am connecting to a mint debian machine over ssh, and try to launch something that asks for permissions, such as synaptic, it freezes everything up to the point that I have to ctlr-alt-f1 and kill the ssh terminal just to get everything to work in ubuntu again. This might happen if the host is something other than mint debian, but I haven't had a chance to test that yet, or try it on a different ubuntu client either. ** Changed in: openssh (Ubuntu) Status: Incomplete = New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to openssh in ubuntu. https://bugs.launchpad.net/bugs/728017 Title: xwindows over ssh causes instability -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Could you please provide a bit more information, in particular: 1. precisely which version of Ubuntu you are using both on the client (from which you ssh) and the server (into which you ssh to run X commands) 2. What is running on the server while you've ssh'ed in? Please give 'ps -ef' output on server) and what window manager you use on the server. 3. What sort of network link are you doing this on 4.
