Hi, I have spent most of the last two weeks battling with tigervnc built from source on x86-64 kubuntu 9.10
The results are pretty good and certainly provide the basic tech support functionality I was looking for. However, I think I have found some significant bugs that you may want to look into. 1. display :0 size is not detected correctly 2. Bandwidth auto-detection is badly wrong in the context I am running. 3. performance is very poor unless I compress the the ssh link. What I built: x86-64 build using ubuntu source pkgs for xorg-xserver copied onto the tigervnc-1.0.0.tar.gz tree. ./configure CFLAGS="-g -O2" CXXFLAGS="-g -O2" FFLAGSS="-g -O2" \ LDFLAGS="-Wl,-Bsymbolic-functions" --disable-xvfb --disable-xnest --disable-xorg Target hardware: HP laptop using Intel GM45 and i915 from Xorg.0.log it loads i956_dri.so and used Modeline 1366 x 768 VNC context: All tiger vnc software is run on the remote kubuntu box via ssh from local linux system. r...@local# ssh -C -X -L 5900:localhost:5900 remote.dyndns.info r...@remote:~# vncviewer localhost:0 The bugs: 1. This works pretty well but the vnc server sends 1366 x1366 . Nearly the double of the correct size , the extra being a black areas below the desktop image in the client window. 2. The F8 connection information shows an estimated bandwidth of 20000 kb/s . This must not be testing the right thing. The link via internet is about 380 kB/s on remote and and only 88kB/s on local. 20Mb/s must be looking at localhost on remote. 3. I have to use compression on the ssh link to achieve reasonable performance. In this context 24b colour is a pretty sluggish but functional. 256 colours is usable provided there's not animated content. Starting ssh without -C , it takes about 2 minutes [sic] to redraw the desktop. What I have is not tops but adequate for remote tech support. As such it is satisfactory, but I think I have probably pinpointed a couple of issues that may have been outside current test contexts. If you would like more details on the conditions that produce these errors, please get back to me.
