People (esp. John) have reported occurrences of a very sluggish behaviour of various applications when run in X2Go sessions.
Add me to that list (and my co-workers).
Noted! :-)
We developers can now confirm this. Ubuntu users reported this earlier, Debian user can now also experience such a sluggishness.
Reproduce on Debian:
- add squeeze-backports archive to your system
- install iceweasel (esr version)
This will drag in a libcairo from squeeze backports that is very probably the cause for making some applications very slow within X2Go sessions.
Libcairo is used in all GTK applications and is a layer between GTK and the rendering backend (X11, OpenGL, ...). With some recent version of libcairo the sluggishness got introduced...
Would it help to mask/block the libcairo from squeeze-backports? Or test with a newer version from wheezy? Maybe I can squeeze that in next week...
When blocking from squeeze-backports you block out latest
iceweasel/icedove and many other libcairo/gtk based packages as well.
For wheezy, an installation without the slow libcairo is rather unpossible.
Greets, Mike
