I'm noticing some very sluggish GUI behavior on certain applications when using x2go. I'm using x2go with a Windows client against an Ubuntu 14.04 server using LXDE window manager.
Certain graphical applications are very slow (to the point of being unusable):
- gedit
- eclipse
- Sublime Text
- Google Chrome
Other graphical applications perform quite well:
- Firefox
- Terminator
- Libreoffice
I suspected it was a 'libcairo2' issue, as I've seen this before on older Ubuntu systems.
https://bugs.freedesktop.org/show_bug.cgi?id=32014
However, both gedit and libreoffice use libcairo2 and exhibit vastly different performance: $ ldd /usr/lib/libreoffice/program/soffice.bin | grep cairo libpangocairo-1.0.so.0 => /usr/lib/x86_64-linux-gnu/libpangocairo-1.0.so.0 (0x00007fbbdfa13000) libcairo.so.2 => /usr/lib/x86_64-linux-gnu/libcairo.so.2 (0x00007fbbdf708000)
$ ldd which gedit | grep cairo
libcairo.so.2 => /usr/lib/x86_64-linux-gnu/libcairo.so.2
(0x00007f898c8e9000)
libpangocairo-1.0.so.0 => /usr/lib/x86_64-linux-gnu/libpangocairo-1.0.so.0
(0x00007f898afbb000)
libcairo-gobject.so.2 => /usr/lib/x86_64-linux-gnu/libcairo-gobject.so.2
(0x00007f898a430000)
Could it be a GTK version thing? Anyone have any ideas? Not sure what the commonality is between applications that perform well vs. poorly and where to go from here.
Thanks, Eric
