Bug 641596

Thank you very much for your report.

I tried to reproduce and here, the plugin fails to load completely.
Checkin my .xsession-errors, I can see lines like:
'/usr/lib64/compiz/libezoom.so' : /usr/lib64/compiz/libezoom.so: undefined symbol: _ZNK5boost13serialization13typeid_system27extended_type_info_typeid_012is_less_thanERKNS0_18extended_type_infoE

And you please verify if you have the same or a different issue? This would make it easier to identify the issue.

As far as I can judge it, the module get loaded for me:

tamas@milleniumfalcon:~> pstree -p | grep comp
        |                `-ksmserver(6870)-+-compiz(6920)---kde4-window-dec(6921)
tamas@milleniumfalcon:~> lsof -nP | grep 6920 | grep -i zoom
compiz    6920      tamas  mem       REG                8,2     39648  424735 /usr/lib64/compiz/libezoom.so


Additionally, I can't find the text 'zoom' in .xsession-errors.

I'm using the compiz packages shipped with openSUSE 11.3, not the ones from any extra repository. Can it be your problem?

BTW, my ~/.config/compiz/compizconfig-1/Default.ini file looks like this:

Some more additional info: I'm using the newest Xorg packages from http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.3 (otherwise my Xorg would crash several times a day), and I updated my kernel just now. However, desktop zoom plugins are known not to work since about switching compiz 0.8.6.

In fact this desktop zoom functionality is very useful. One of the main reasons I use compiz instead of compositing kwin (which seems to be only fancy but not quite useful).

Thanks for the info.. That means the problem changed between 0.8.6 and 0.9.0... but it surely did not get any better.

I donwloaded the compiz, compiz-plugins-main and compiz-plugins-extra SRPMS from http://download.opensuse.org/source/distribution/11.3/repo/oss/suse/src and recompiled 'em all bit without ANY patches. Now both desktop zoom and enhanced desktop zoom works! It assume it means that the problem is in one of SuSE's patches. My suspicion that the problem is in the compiz package, because firstly I only recompiled compiz-plugins-main (which hold the ezoom plugin), without patches, and this method didn't solve the problem. However, recompiling every compiz package without patches solved the problem.

Can you take a look at it, please? The zoom plugins are really amongst the most valuable features of compiz (if not the single best).

Hooray, I've found the root cause of the problem. Removing every single patches except one, I figured out that the symptoms are caused by the "bug-449168-avoid-independent-output-painting.diff" (https://build.opensuse.org/package/view_file?file=bug-449168-avoid-independent-output-painting.diff&package=compiz&project=openSUSE%3A11.1%3AUpdate) patch which changes only one line (or to be more specific only a single C operator).

This patch was originally made for compiz 0.8.4. Is it still necessary in 0.8.6? Too bad I'm not allowed to access https://bugzilla.novell.com/show_bug.cgi?id=449168

Can you take a look at this patch?

Anybody there?

Thanks for waking me up. This patch had actually been dropped from the X11:Compiz packages shortly after you found the pointer.

As for Compiz 0.8.6 as shipped with openSUSE 11.3: I created a branched package without this patch identified as the cause.

Can you please give the packages in http://download.opensuse.org/repositories/home:/dimstar:/bnc641596/standard a try? (only a new compiz package... the rest should not require a rebuild). Those are packages to be used on stock 11.3 compiz, without any other repos for compiz enabled.

if those works, we can check with maintenance if the issue is critical enough for an online update (but we need testing first of course).

(In reply to comment #9)
The repository at URL http://download.opensuse.org/repositories/home:/dimstar:/bnc641596/standard does not exist.

sorry, publishing was disabled.. the repo is now available.

I've done the update, and it seems to fix the bug.

needinfo

maintenance team: would you consider this worthy for an online update?
The patch added was long / old / unmaintained and according to upstream wrong anyhow (was an inheritance from early 0.7.x times I think).

without the patch, the reported issue seems to be resolved (update would be for 11.3 only I think. 11.2 had compiz 0.7.x). Factory does not need the fix, as there we are on compiz 0.9.2 already.

From my point of view: yes (+1)
