Dmitry Shachnev, thanks for your quick response. >"Christopher, why do you think this is a bug in gnome-panel?"
I'll let you make the call on what is the root cause package. Despite this, as per https://launchpad.net/ubuntu/+source/gnome-panel gnome-session-flashback is provided by gnome-panel (not gnome-session), which this report was supposed to be scoped to how xrdp'ing (among other protocols mentioned) doesn't properly present a GUI when using gnome- session-flashback (and Unity). What I can speak to is the issue that I thought this bug report was scoped to still isn't addressed. However, if you find that this report should be re-scoped, I'm happy to file a new report on it. "I see that gnome-panel is not even started in your screenshot." I'm not sure what you are talking about. To clarify what you are seeing, it is my host computer (whose environment is irrelevant, could be Windows, etc., but happens to be using Ubuntu) using a remote desktop client (Remmina), remoting into a gnome-session-flashback environment (the horizontal black/white lines, with a white diagonal line). >"I don't have the environment needed for reproducing this so can't look at it" Have you ever tried virtualization with Virtualbox? It's available via the Ubuntu repositories, and works quite well. Also, one may setup a temporary live environment as noted in https://bugs.launchpad.net/ubuntu/+source/gnome- session/+bug/1251281/comments/58 . ", but patches are welcome." As I'm not a developer by profession, nor have that as a background, this will unfortunately not be coming from me. Ryan Tandy, thanks for testing to this issue, it is greatly appreciated. >"Whether or not this works with xrdp probably depends on how your session is set up." Hmmm. All I did was a default install from http://cdimage.ubuntu.com /daily-live/current/ , install xrdp and gnome-session-flashback, log into gnome-session-flashback and attempt an RDP. >" I just tried installing gnome-session-flashback and xrdp on the vivid daily CD; the default configuration does nothing, but the following ~/.xsession: env DESKTOP_SESSION="gnome-flashback-metacity" XDG_CURRENT_DESKTOP="GNOME-Flashback:Unity" gnome-session --session =gnome-flashback --disable-acceleration-check does load the session. (but the keyboard layout seems wrong somehow... :/)" Unfortunately, I'm not following you here. Could you please provide this information in a keyboard click-for-click fashion? As well, just to clarify, making the modifications you advised above allows you to see an actual desktop GUI (icons, windows, etc.)? >"If xrdp needs to be adjusted to set this up by default, or documented somehow, maybe that should be a separate bug against xrdp." I already started a support article on xrdp at https://help.ubuntu.com/community/xrdp . Once I can reproduce your results, I'm happy to put it up there in a keyboard click-for-click fashion. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-panel 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) Status in The GNOME 2 Session Manager: Fix Released Status in gnome-panel package in Ubuntu: Incomplete Status in gnome-session package in Ubuntu: Fix Released Status in gnome-panel source package in Trusty: Incomplete Status in gnome-session source package in Trusty: In Progress Status in gnome-panel source package in Utopic: Incomplete Status in gnome-session source package in Utopic: In Progress Status in gnome-panel source package in Vivid: Incomplete Status in gnome-session source package in Vivid: Fix Released Status in gnome-session package in Debian: New Bug description: == Impact == It was impossible to launch a gnome-session-based desktop on a system where hardware accelerations is not available (such as old hardware, or when using a remote desktop). That looks like a quite popular use case — more than a hundred of people marked this bug as affecting them. == Test Case == The original bug description below contains a test case. == Proposed Fix == The fix backports an upstream commit which adds --disable-acceleration-check commandline option, and makes Upstart user session pass that flag to gnome-session when the session is gnome-fallback (aka gnome-flashback-metacity). Of course, that option can be used with other sessions as well. This was fixed in vivid in version 3.14.0-2ubuntu4. == Regression Potential == The option was accepted upstream, and nobody complained so far. So the regression potential should be low. This bug will cause static grey or black screen instead of opening remote session using Forwarded-X/XRDP/VNC/NX/X2GO/Chromoting from x2goclient, rdpclient(reminna/vinagre/mstsc), SSH, VNC, NOMACHINE and etc. == Original Description == 1) lsb_release -rd Description: Ubuntu 14.04 LTS Release: 14.04 2) apt-cache policy gnome-session gnome-session: Installed: 3.9.90-0ubuntu12 Candidate: 3.9.90-0ubuntu12 Version table: *** 3.9.90-0ubuntu12 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main amd64 Packages 100 /var/lib/dpkg/status 3) What is expected to happen is when one installs xrdp on the host and attempts to use remmina or vinagre on a Ubuntu 14.04 client to RDP in, it works. 4) What happens instead is it shows a gray static screen as per attached screenshot.
