Bug Description

Trying to start vnc4server via "vnc4server -geometry 1400x990 :1" fails always; the .vnc/$HOST:1.log leads off with

  Unrecognized option: -extension

Doing an strace on the vnc4server binary shows that it's trying to execute Xvnc4 like so:

  Xvnc4 :1 -desktop "denisovich:1 (steve)" -auth /home/steve/.Xauthority -geometry "1400x990" -depth 16 -rfbwait 30000 -rfbauth /home/steve/.vnc/passwd -rfbport 5901 -pn -extension XFIXES -fp "/usr/X11R6/lib/X11/fonts/Type1/,/usr/X11R6/lib/X11/fonts/Speedo/,/usr/X11R6/lib/X11/fonts/misc/,/usr/X11R6/lib/X11/fonts/75dpi/,/usr/X11R6/lib/X11/fonts/100dpi/,/usr/share/fonts/X11/misc/,/usr/share/fonts/X11/Type1/,/usr/share/fonts/X11/75dpi/,/usr/share/fonts/X11/100dpi/" -co /etc/X11/rgb

but that Xvnc4 no longer recognizes the -extension argument. This was working with vnc4 4.1.1+xorg1.0.2-0ubuntu7 in lucid.

Backing out the change in, the only remaining (code) dependency fixes it so that Xvnc4 will start. And it is capable of launching a full gnome-session, as that's what I have my .vnc/xstartup configured to do.

The fix is rather easy: just replace
$cmd .= " -extension XFIXES";
#$cmd .= " -extension XFIXES";
around line 263 in /usr/bin/vnc4server

Eduard: yes, that's what the patch in the attached bzr branch does. It's also available in package form from my ppa at . It causes vnc to start; however, the vnc server is acting like the Super key is pressed all the time, which is making it less useful.

Steve: oh, thanks.
True, I can confirm that the SUPER key is always pressed. On my lucid test system, I was only viewing so I did not recognize.

@Eduard & @sbeattie: Can you try changing the line from:
$cmd .= " -extension XFIXES";

to the following combinations, and see if one of them resolves the issue. It would be good to get this fixes prior to the next upload:
$cmd .= " -clear_keys";
$cmd .= " -repeat";
$cmd .= " -repeat -clear_keys";

Both of these options are unknown to my Vnc4 version ( 4.1.1+xorg4.3.0-37ubuntu1). Both result in an unknown option error when trying to launch via vnc4server.

I confirm the "Super key" being like always pressed.
Should I open a new bug ?

Yes, please do (and report back here). Thanks.

Ah, it turns out the Super key issue ended up being bug 568401, which was an issue in the indicator-applet itself. Fortunately, this was addressed in a Stable Release Update.
