tiger vnc xorg 111 patch (fedora tigervnc-1.1.0-5.fc18) (6.22 KB, patch)
2012-06-17 10:13 CEST, Arnaud GIBERT
Details | Diff

Description Bill Randle 2012-03-21 19:53:43 CET
Description of problem:
[   163.626] (II) LoadModule: "vnc"
[   163.634] (II) Loading /usr/lib/xorg/modules/extensions/libvnc.so
[   163.635] (EE) Failed to load /usr/lib/xorg/modules/extensions/libvnc.so: /usr/lib/xorg/modules/extensions/libvnc.so: undefined symbol: GetMaster
[   163.635] (II) UnloadModule: "vnc"
[   163.635] (II) Unloading vnc
[   163.635] (EE) Failed to load module "vnc" (loader failed, 7)

Version-Release number of selected component (if applicable):

How reproducible:
100% consistent

Steps to Reproduce:
1. Install tigervnc-server-module
2. include Load "vnc" line in xorg.conf
3. restart Xserver and view Xorg.0.log file

Seems to be a common problem as a Google search turned up similar problem with Fedora 16, which now has rebuilt package to solve the problem.
Comment 1 Bill Randle 2012-03-28 18:47:56 CEST
Changing priority to High, as this is very important to my usage, as the system this is installed on is remote. I also looked at some alternatives, such as x11vnc but it does not seem to be as smooth as Xvnc (as used on a Mageia 1 system). I hope someone will rebuild this package soon.

Priority: Normal => High

Comment 2 Marja Van Waes 2012-05-26 13:03:11 CEST

This bug was filed against cauldron, but we do not have cauldron at the moment.

Please report whether this bug is still valid for Mageia 2.

Thanks :)

The same bug seems to be corected for Fedora :

This bug is still valid for Mageia 2.

tiger vnc xorg 111 patch (fedora tigervnc-1.1.0-5.fc18)

This xorg 111 patch version don't use unexported GetMaster function.
Comment 5 Arnaud GIBERT 2012-06-17 10:17:59 CEST
I've apply this patch against the last mageia tiger-vnc package.
You can test the result here: ftp://ftp.rx3.org/pub/arc/pkg/tiger_vnc/1.1.0/

On my mageia/2 it seems to work.
More tests are needed.

The problem resurfaced in Mageia 3. Currently running Cauldron for Mageia 3.

Comment 7 Arnaud GIBERT 2013-05-11 23:47:14 CEST
IMHO, this bugs has never been officially corrected: the patch I've proposed has never been release...
One year later on my Mageia 2, it's run smoothly.

Hardware: i586 => All

Comment 8 Samuel Verschelde 2013-08-26 15:01:48 CEST
I had a look at the package in cauldron: patches already have been synced from Fedora so the cauldron version should work now. 

I'll see if I can provide update candidates for MGA2 and MGA3.

See bug #10181
The update Alfonso Vera is preparing should fix you problem at the same time.

Comment 10 Vincent D 2013-09-04 00:23:58 CEST
Same problem here, and unable to find and compile some .src.rpm for mageia 3 (x64): in any case (original or Comment 5 version) xserver110.patch fails.

What is the status of this bug ? Is there a good rpm somewhere ?

Comment 12 Vincent D 2013-09-09 19:57:50 CEST
Precompiled packages work fine for Mageia 3.

But compilation of tigervnc-1.1.0-3.1.mga3.src.rpm fails ending by:

  CC       Xvnc-buildtime.o
  CXXLD    Xvnc
../../xkb/.libs/libxkb.a(ddxLoad.o): In function `Sha1Asc':

Anyway thank you for the upload !
Comment 13 Alfonso Vera 2013-09-09 22:58:57 CEST
Hi Vicent:
I can't reproduce your problem :-(

I build done 
mga2: tigervnc-1.1.0-3.1.mga2.src.rpm 
mga3: tigervnc-1.1.0-3.1.mga3.src.rpm 
rpmbuild --rebuild tigervnc-1.1.0-3.1.mgaX.src.rpm 

Comment 14 Samuel Verschelde 2013-09-10 10:21:02 CEST
Vincent, the Mageia 3 update candidate should be discussed in bug #10181, this one is now for the Mageia 2 update.

About your build problem, make sure you use openjdk-devel in version 1.6

Comment 15 Dave Hodgins 2013-09-11 04:32:40 CEST
Is tigervnc-server-module intended only for headless servers?

I'm testing under virtualbox, using the procdure at
and having the module loaded stops X from being displayed in
the guest.

I can ssh into it, and use vncviewer, though so far only
see a black screen with the clipboard options, and the option to send
the primary selection to viewers.

If I don't load the module in Xorg.conf, then the script from
works, so both the guest and the vncviewer can work with the same screen.

Comment 16 Dave Hodgins 2013-09-11 05:20:33 CEST
Looks like the problem in comment 15 is only under VirtualBox.

I tested on real hardware, and it's working.  I'll test x86_64 tomorrow.

Comment 17 Dave Hodgins 2013-09-12 02:12:51 CEST
Advisory 5045.adv committed to svn.

Testing complete on x86_64.

I'll hold off validating this update until Mageia 3 has been tested too.
