Hi everyone, First, I am a big fan of the remote display capabilities of X, thank you very much to all who have worked on this project over the years.
Also, I am not sure if this is an Xorg issue per se or a bug in my own code, however am at wits end and am hoping someone can point me in the right direction. For my open source project - eBrainPool (ebrain.in) - I have been working on a tunnel plugin working over the Retroshare network that will allow SSH X forwarded sessions. The tunnel works for the most part of it, though I am seeing the following behaviour that I have not yet been able to debug : - The test configurations for the below tests have two machines. Machine 1: Debian Unstable with X server 1.18.4 and OpenSSH 7.3 (also tried with OpenSSH 6.9). This machine is an i7 with Intel accelerated graphics and uses the intel Xorg driver. Machine 2: Debian Testing with X server 1.16.x and OpenSSH 6.7. This machine is a Core2Duo with Radeon graphics and the radeon Xorg driver. Both machines use Gnome3. - Simple X clients such as xclock, etc run without any hitches through the tunnel over the Internet via Retroshare. More complex X clients such as gnome-calculator,gedit,etc work for a short while before causing a freeze of the entire X server. I have to kill SSH by going into a tty before I can resume using my Gnome session. Once the SSH session is killed, the session resumes normally and I don't need to log back in. - If I use SSH X forwarding between my two machines over LAN and without my tunnel, then everything works without a hitch. - If the X server is within a Virtualbox guest running either Debian Stable, Unstable or Ubuntu 14.04 then all works fine through my tunnel. I can forward applications to this X server through my tunnel and use them without any hitch. - If I start Xephyr on either machine and use ssh to forward to this display, then even through my tunnel, all works well. No X freezes - neither of the primary Xorg server nor of Xephyr. - I tried using the Vesa xorg driver instead of the Intel driver on Machine 1, just to see if that had any change in behaviour (even though I see this same behaviour with the radeon driver). No joy. When using the tunnel, the X server still hangs up. Again, I am not sure if this is an issue with Xorg, SSH, Retroshare or most likely my own tunnel code, however since it all works within Virtualbox and Xephyr but not otherwise I am at wits end as to where to look. I realize the above information is sketchy however I feel to debug this any further I require guidance from someone with more intimate knowledge of X than myself. Am hoping someone will be able to see something here that I am missing, or point me out as to how I can gather more information that would help debug this. Thank you so much for your time, I truly appreciate any help.
