[Dorset] X through ssh mystery
Hi I've noticed for some time something which baffles me with X forwarding over ssh and using Firefox (Iceweasel in Debian). I can open a remote Iceweasel session, served up locally, in the normal way: localmachine$ ssh -X remotemachine iceweasel However, if I already have a local iceweasel session running, the above command just opens another local iceweasel session. What am I missing here? Debian Squeeze on both machines. This is specific only to Iceweasel (as far as I know). Nothing immediate leaping out at me with -v or -vv.

Thunderbird is the same, and Firefox too IIRC. It must detect the other session via the X server somehow. I haven't tried it, but might this help? http://kb.mozillazine.org/Run_multiple_copies_of_Thunderbird_at_the_same_time#Making_Thunderbird_behave_differently -- Next meeting: Bournemouth, Tuesday, 2012-12-04 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue

What am I missing here? Curious isn't it? Thunderbird is the same, and Firefox too IIRC. It must detect the other session via the X server somehow. Yes, it looks through the X window hierarchy for its `Mozilla' properties and finds the window that best matches, e.g. Firefox, same user, same profile. $ xlsatoms | gi mozilla 440 _MOZILLA_VERSION 441 _MOZILLA_LOCK 442 _MOZILLA_COMMAND 443 _MOZILLA_RESPONSE 444 _MOZILLA_USER 445 _MOZILLA_PROFILE 446 _MOZILLA_PROGRAM 447 _MOZILLA_COMMANDLINE $ $ xprop -id 0x1c000ff | g _MOZILLA _MOZILLA_PROFILE(STRING) = default _MOZILLA_PROGRAM(STRING) = firefox _MOZILLA_USER(STRING) = ralph _MOZILLA_VERSION(STRING) = 5.1 $ To tell the Firefox you've started not to do that use -no-remote AIUI. However, don't let it try and use the same profile as another running Firefox and profiles aren't designed to cope. Instead, give it another profile name with -P. -ProfileManager lets you create a new one.

I'm sure you realized this, but it's perhaps worth pointing out that if you are running a version locally and version remotely on your local X, -no-remote would be safe to use unless you are doing something really bizarre with mounting shared user profiles over the network. -- Next meeting: Bournemouth, Tuesday, 2012-12-04 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread on mailing list: mailto:dorset@mailman.lug.org.uk How to Report Bugs Effectively: http://goo.gl/4Xue
