I have ~100 business users in 4 offices in 4 cities in 2 states doing all their daily office work in X2GO/MATE/Debian, and it just flies over the WAN. I just got finished watching (and listening to) Mike Gabriel's talk at Debconf on YouTube via X2GO over a 6mbit connection. Impressive. then I have something delicious for you, as well: 1. Install a fresh machine as X2Go Server (e.g. with MATE). 2. Upgrade to X2Go Server from the nightly builds 3. Install mTelePlayer server-side (NEWEST stuff): apt-get install mteleplayer 4. Install PyHoca-GUI from the nightly builds on your Linux client: apt-get install pyhoca-gui 5. Install the client-side part of mTelePlayer: apt-get install mteleplayer-clientside Open a (not too large, we are working on performance) video file (not a video on a website, a real video file!) inside an X2Go session with mTelePlayer and be happy...

Re: [X2Go-User] problem getting x2go to work.
Mike- I finally noticed in my client that when I killed the x2gostartagent process, if the client is still open when I issue the kill command, then a window appears in the client this message over and over: Connection failed my_username is not authorized at /usr/lib/x2go/x2gosqlitewrapper.pl line 526. The client really ought to show these kinds of errors without you having to kill the process on the server. But there is a bug in the Mac client where you cannot check the show details button until *after* a successful login. Therefore you never get to see the verbose output when your logins fail -- which is when it would be most useful to see it! Anyway after some digging on that error message, I figured out that my problem was that my Bitnami AMI had me signing in as username ubuntu which is really just an alias to the user bitnami. But because I was signed in as a different username than the name of the home folder, it was messing up. When I logged instead using bitnami as the username, then suddenly it worked... kind of. gnome-session --session=gnome-fallback does not work for me... I'd see the screen but was not able to click on anything. I thought, maybe I have the wrong bindings installed, so I tried to aptitude install x2gognomebindings but it just kept saying this error: Couldn't find any package matching x2gognomebindings. However, the following packages contain x2gognomebindings in their description: x2goserver-fmbindings So then I installed the x2goserver-fmbindings and I still couldn't get it to respond. I could see the desktop but nothing happens if I click. I could also not get on with just using the GNOME selection. I did have better luck with gnome-session --session=gnome-classic but it's still unusably slow. Even on 32k JPEG and with bandwidth set to WAN, stuff just happens way too slow, or doesn't happen at all. I know it's not my connection that's the problem. It's probably because it's an Amazon Micro instance, and it's just dog slow. If I use xfce4, I wonder if it would run faster? I'd like to try your xfce4 steps but I've already installed ubuntu-desktop, so will it hurt me to also install xfce4 alongside it? Can I have both installed? I just want to know if I should start over fresh with a new AMI. I don't need anything fancy, just want a GUI for managing files and running basic utilities like a git client.

You'll notice that it runs gnome-flashback.sh in my command, that's because it doesn't work to connect the normal way either, so I tried the steps outlined in this e-mail from this list: http://lists.x2go.org/pipermail/x2go-user/2014-May/002260.html There is no need to follow those steps because you are using Ubuntu 12.04.4, not Ubuntu 14.04. Ubuntu 12.04 has GNOME 3.2, not GNOME 3.8. GNOME 3.6 and earlier have gnome fallback session, which is compatible with X2Go. flashback isn't even available until GNOME 3.8, it's what fallback

OK, I think I see the problem. ubuntu-desktop. You have the UNITY desktop environment installed, not vanilla GNOME. Please try specifying UNITY as your session type. Our logic in the x2goserver package will make sure Unity runs in Unity 2d mode. This mode is provided by package unity-2d. ubuntu-desktop depends on unity-2d, so you do have unity-2d installed. Also, as for XFCE: It's lightweight and it never tries to use 3d effects, so it runs faster to one degree or another. I recommend installing it according to my instructions. Absolutely, you can have both desktop environments installed. If you had a physical machine, you would select which desktop environment to use at the display manager's greeter (the graphical login screen.)
