xrdp server that ships with SLES 11 SP3 takes 10 times more bandwidth then MS Windows Terminal Server. when we connect a Windows Terminal Server, each session consumes only 40kbps, while connecting from the same clients to xrdp server takes atleast 300kbps. I came to know that the issue could be fixed via installing xrdp-master ver 0.9 available to download from https://github.com/neutrinolabs/xrdp/archive/master.zip.

and start following the installation manual @ http://www.xrdp.org/index.php?option...ments&Itemid=7 all went good/smooth else when I run the "sh buildx.sh /opt/X11rdp" I got the following error:
checking for XDRIINFO... yes
checking for library containing glXGetProcAddressARB... no
configure: error: in `/opt/xrdp-master/xorg/X11R7.6/build_dir/xdriinfo-1.0.4':
configure: error: cannot find GL library - make sure Mesa or other OpenGL package is installed
See `config.log' for more details
configuration failed for module xdriinfo-1.0.4

I then went to YaST > Software Manager, search for "opengl" and install all the packages even I installed the packages from SLED 11 SP3 media , but still got the above error. please help me how to proceed further and resolve this dependency ?
