[Bug 1421325] Re: xdmcp server ubuntu 14.04 login error
Hello, I am also affected by this bug - cannot login using any and all XDMCP clients that I know of into my server running Ubuntu 14.04. I am reluctant to switch to lightdm from gdm for a variety of reasons. I also would like to understand how active this bug is. It seems to me that if it's a "real" bug it should affect quite a lot of people - not just 2 of us. Or are we doing something wrong in the sense of not configuring something correctly.

Just to reproduce the problem you are welcome to get it from my ftp server: ftp://mplotkin.com (login as anonymous). Sorry, it can be slow - I am using a very old computer for ftp... You need to install all three (appropriate of course) packages on the server and just nxclient on the client. Michael.

I'm sorry - I don't understand this at all: local gnome-session always worked all right without this fix in trusty-proposed, and the remote gnome-session doesn't start at all with this fix in trusty-proposed but without other changes from ppa:rtandy/flashback repository. At least this was my result...

Did reasonably extensive testing last night of the proposed fix for Trusty. I believe that my results are very similar to Xavier: after I installed all updates related to this bug from trusty-proposed repository (pre-released) I couldn't start remote X2go session at all. In /var/log/messages I found information about segfault in libgnome-desktop-3-7: Apr 1 05:17:12 marina-net /usr/bin/x2goruncommand: launching session with Xsession-x2go mechanism, using STARTUP=gnome-session --session=gnome-flashback --disable-acceleration-c\ heck Apr 1 05:17:20 marina-net kernel: [ 1747.973711] gnome-session[7806]: segfault at 18 ip 7fc4c3952196 sp 7fff7f38a820 error 4 in libgnome-desktop-3.so.7.0.0[7fc4c393+3\ 1000] It appears that libgnome-desktop-3-7 wasn't update since July of 2014 and its version was 3.8.4-0ubuntu3. So I installed updates from ppa:rtandy/flashback repository according to Xavier instructions, which includes updating libgnome-desktop-3-7. After update the version of libgnome-desktop-3-7 became 3.8.4-0ubuntu4. Actually it updated 16 other packages as well at that time. After this update everything began working very well. So my conclusion is that the fix in the trusty-proposed repository as it stands there right now is not helpful at all, but the version in ppa:rtandy/flashback repository works fine.

Thank you Michael, very much, but in a sense my question was whether there is (there would be) a way to have this option - --disable-acceleration-check always (by default), so my users wouldn't need to change their existing setups of many NX client sessions that they already have. Also NX has an option to start different sessions (Desktops as they call it) including Gnome or, alternatively, run any specified command. If I specify to run gnome-session command - it doesn't work correctly at all. I don't know exactly how they lunch gnome-session when I select GNOME Desktop in their configuration menu (there are no sources as you know) and I didn't spend much time yet investigating this.

That's what you will have to do with X2Go at least. I wrote the logic in X2Go for --session=gnome-flashback. I still need to write the logic in X2Go for --disable-acceleration-check. Once I do, X2Go users can simply select GNOME as their session. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/1251281 Title: gnome-session-flashback/Unity fails to start without hardware acceleration in cloud/remote environments (Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-session/+bug/1251281/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Thank you Ryan for helping to resolve this problem. I've been waiting anxiously for this problem being fixed because it's the main reason I cannot start using 14.04 (and have to use 12.04) on a lot of systems. I have a question - do you see any problems using original NX software with this solution. For mostly historical reasons I've been using original NX software (NX 3 from NoMachine) and have their client software installed on quite a few computers. Thank you, Michael. On 06.03.15 14:38, Ryan Tandy wrote: I am happily running GNOME Flashback with the FreeNX server, and nx-libs from the X2Go stable PPA, on multiple Trusty terminal servers and it has been quite stable. The gnome-session --disable-acceleration-check option is needed, and also bug 1416081 has to be fixed to stop unity-settings- daemon from crashing. I have uploaded all the necessary patches to ppa:rtandy/flashback and attached them to these bugs. In the PPA I also patched gnome-session-flashback to use --disable-acceleration-check, but it's not really necessary -- just for symmetry :). Attached is the FreeNX config file I use. Note it relies on the Upstart session job to pass --disable-acceleration-check to gnome-session. For X2Go, /usr/bin/x2goruncommand has to be adjusted similarly; I will follow up to their tracker (http://bugs.x2go.org/cgi- bin/bugreport.cgi?bug=774) soon. I hope these patches can be considered for vivid, and maybe for trusty/utopic SRU as well.

Hello, I'm sorry to bother, I know that practically the same question was asked a few months ago by Nicholas DiPiazza, but it wasn't directly answered. - Is there any time frame to fix this problem in the official distribution of Trusty? Similarly to what was said previously - this is the main reason we cannot upgrade to 14.04 from 12.04. It's absolutely critical for us to use remote sessions using NX (or any other method to have remote gnome session that would provide speed as good as NX does).
