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.
