Hi Neal

Thanks for the pointer to the work around.

Do we know why this started to happen with F24?

Thanks again.

Hi

I'm connecting from a Mac (X2Go Client v. 4.0.5.1 (Qt - 4.8.7)) to Fedora 24 with a xfce session using the x2goserver-4.0.1.19-11.fc24.x86_64 packages from the fedora repos.

On starting emacs, I get the error below. This issue seems to have been around for a while in similar forms, but didn't affect me under Fedora 22.

Is anyone in a position to confirm this issue on Fedora 24 and suggest a work around? I tried setting various environment variables suggested on various web pages for similar issues and in the bug report noted in the error message (and checked /etc/PROBLEMS), but nothing was effective.

emacs starts fine in an xfce session at the console.

Thanks

No, maybe an update to gtk?

  I have run into some random problems with the x2go server crashing

when I invoke programs, sometimes vi, sometimes synaptic.

Dear all,

Have there been any further developments regarding the problem of Emacs crashing when run over x2go? I'm experiencing the same issue and would love to know if there is any workaround that doesn't involve recompiling Emacs or running it in text mode (as mentioned in the Fedora bug report at <https://bugzilla.redhat.com/show_bug.cgi?id=1349412>).

I can't speak for Robert's problem, which seems to be unrelated. In my case, Emacs is the only program that crashes, though other GTK+ programs have problems displaying the pull-down menus. See the "GTK+ pull-down menus not displayed" thread in this list.

Are you running with an Nvidia card?

The client has an Nvidia card, yes. The remote server doesn't.

I had to install VirtualGL and run some application through a proxy to get them to work.

vglrun -c proxy xterm -ls

It's not clear to me how or where you're suggesting I use VirtualGL. Do you mean that I should configure my x2go client to launch "vglrun -c proxy xterm -ls" instead of just "xterm" as the "Single Application"? If so, that doesn't work; the x2go session connects but then terminates immediately.

If I use x2go to launch a remote xterm as usual, and then type your vglrun command in that xterm, then it returns with the error "Invalid MIT-MAGIC-COOKIE-1 key[VGL] ERROR: Could not open display :0.".

Yes, that was the workaround referenced in my original post. As I said, I'm not particularly keen on recompiling from source. This isn't even possible for users who connect to a remote system on which there are no development tools and no root access to install them.

This is rather old, I missed that when reading it, sorry.

But here's a small example code that might trigger the problem:

Great news for Fedora users. If there's no fix or workaround coming in the near future, I might do the same for openSUSE, if I can wrap my head around OBS.

Incidentally, here's a similar bug report for openSUSE:

I'm not affected by this bug, as I'm not an Emacs user myself, but I recently discovered: <https://copr.fedorainfracloud.org/coprs/nbecker/emacs-x2go/>

I'm assuming this "nbecker" is the Neal Becker <ndbecker2@gmail.com> who chimed in on this thread before.
