Anybody try to configure for example ubutu to configure x2goserver

I have read that for example OpenNX client for neatx or freenx
server recommend to use this because libjpeg-turbo have speed
improvement than standard libjpeg and it will be use full to
reduce transfer for x2go session. I don't know how to configure
(or is it possible?) x2goserver on ubutu to use libjpeg-turboRegards
libjpeg-turbo support (from my perspective) is a distribution
issue. Libjpeg-turbo is pending for Debian sid inclusion: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=612341As we do not have plans to ship libjpeg-turbo within the X2Go
repository currently, I guess we will have to wait for distro
inclusion in Debian/Ubuntu.With other distros that already have libjpeg8 (optionally) replaced
by libjpeg-turbo, it should be possible to compile NX
(redistributed) against the faster libary.There also is another NX related project on git.ethersoft.ru that
provides NX with libjpeg-turbo. However, that repos only builds NX
for FreeNX.I have just tested an NX build against libjpeg-turbo. The
libjpeg-turbo libraries I obtained from here: http://people.debian.org/~fabo/libjpeg-turbo_1.1.90+svn704-1/The test system was a Debian squeeze (so backporting from some brand
new SID package is possible).When using 16m-jpeg-9 compression over a UMTS (HDSPA) uplink the
difference between libjpeg and libjpeg-turbo is smashing!!! It
becomes so much smoother...From my perspective, we should start testing on nx-libs with
libjpeg-turbo in the nightly repository in the very very very near
future.The change-over is easy: if libjpeg-turbo62 is installable in the
build chroot, NX builds against that one. If it is not present, it
builds against libjpeg62.@Developers: please give feedback on the proposed step.
Here is a recipe how to test NX with libjpeg-turbo:
ON SERVER
Install libjpeg-turbo from X2Go heuler repository (Debian-only)
apt-get build-dep nx-libs apt-get source -b nx-libs
(still on server) cd .. dpkg -i *.deb
ON CLIENT
Install your self-built packages libxcomp3 and nxproxy also on client
Happy testing
The above should work with Debian squeeze, wheezy and sid as test
system (amd64/i386).
Greets, Mike
