X2Go clean sessions script is a daemon script. It should be possible to execute multiple instances, but it should fork into background. There is no --help and --version available, so these optioned commands will just start another instance of the daemon. Interesting, thank you for the explanation. Is there an advantage over letting the user to decide to start in the foreground or in the background by using the ampersand »&«? The script needs root privileges on the file system and it is launched via invoke-rc.d x2goserver start It is not supposed to run with user privileges. Please read the script's Perl code for further insights.

Re: [X2Go-Dev] Attention @Alex, @Mike: Urgent problem with Flash and Iceweasel
Hello, The about:config change works at least for Flash player. If you use Ubuntu/Firefox you can make the fix global by putting in /etc/firefox/syspref.js the following: // prevent flash player windows from overlapping other tabs pref("plugins.force.wmode", "opaque"); Now I don't know the difference between "opaque" or "transparent" and I haven't spent much today to find it out (first google hits didn't help). What I did notice is that this fix doesn't prevent adobe acrobat reader from still having a similar behaviour but I can live without it as it's a horrible browser plugin and there are open source alternatives as long as you don't need pdf forms in the browser. -Original message- From:Stefan Baur Sent:Mon 27-08-2012 09:18 Subject:Re: [X2Go-Dev] Attention @Alex, @Mike: Urgent problem with Flash and Iceweasel To:x2go-dev@lists.berlios.de; Am 26.08.2012 21:07, schrieb John Williams: > I switched from Firefox to Chromium months ago because of this issue.

Yes, Windows client 3.99.2.2. I am using Chromium on linux, not Chrome. I have occasionally had Chromium crash and lockup Xorg, but not very often. I assumed that was just a Chromium issue (it doesn't receive a lot of testing), but I suppose it could be x2go related. > With the link you provided, I found > http://www.nomachine.com/tr/view.php?id=TR04J02675 - that page doesn't seem > to offer a workaround, but links to the page you mentioned. > > What's confusing me here is that that page says "two *more* workarounds", > which means there should be three. > > Any idea what number three might be? I saw that too. I can only guess that it is the way their bug tracking system works, but they are not using it correctly. I don't think there is a third workaround.

In my case, vcxsrv crashes whenever I try to access the proxy settings in Chrome, see my message from back in May: https://lists.berlios.de/pipermail/x2go-dev/2012-May/003991.html I'd be interested to know if you're using Chromium from the stock Debian Squeeze repository or if you're on Wheezy or using a totally different repository for it. Also, could you check what happens in Chromium when you try to access the proxy settings? I'm curious if it works with Chromium, but not with Chrome. -Stefan ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev

I'm curious if it works with Chromium, but not with Chrome. It may be I am seeing similar crashes to you. When I said Xorg locked up, I only meant that nothing in my x2go session would respond (not only chromium, but all mouse clicks were ignored). It may very well be that VcXsrv on the client is crashing, since I was able to recover by quitting and restarting x2go. I think I may even have had to use Windows task manager to kill VcXsrv, but I don't remember (it has been a while since it last happened). I am using the Chromium x86_64 package from the Archlinux "extra" repository. Currently it is at version 21.0.1180.81-2. I never use proxy settings, so I was unsure what exactly you wanted me to test. I just accessed Chromium: Settings...Network...Change proxy settings... and I was shown this message in a new tab: "When running Chromium under a supported desktop environment, the system proxy settings will be used. However, either your system is not supported or there was a problem launching your system configuration. But you can still configure via the command line. Please see man chromium for more information on flags and environment variables." ___ X2Go-Dev mailing list X2Go-Dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/x2go-dev

No, not the same, see below... > I am using the Chromium x86_64 package from the Archlinux "extra" > repository. Currently it is at version 21.0.1180.81-2. Hmm. Debian Wheezy has Chromium-Browser 20.0.1132.57. I might try that soon. > I never use proxy settings, so I was unsure what exactly you wanted me > to test.

Indeed that is what I meant, only that back when I last tried it, Chrome had an option like "advanced settings" that you had to click before the change proxy settings button becomes available. > and I was shown this message in a new tab: > > "When running Chromium under a supported desktop environment, the > system proxy settings will be used.

Please see man > chromium for more information on flags and environment variables." And this is the tab I only get to see after killing all x2go-related processes on the client and reconnecting, as in the very moment when I click the button, vcxsrv goes "zap" on me and dies with the error message shown in my message from back in May. Well, since I have one box running Wheezy, I guess I'm going to give both the latest Chrome and Wheezy's Chromium-Browser a try soon.
