launching applications on fullscreen kill compiz

Bug #138424 reported by Nemes Ioan Sorin on 2007-09-09
Affects Status Importance Assigned to Milestone
compiz (Ubuntu)

Bug Description

Binary package hint: compiz

Gutsy tribe 5.

After installing tribe 5 (I wanna do a fresh install - instead internet upgrade - to see what's new with the new installer) everything work ok with compiz.

After I do regular updates and Install Emerald - all OK again but ..let say after 20 minutes when I launch ..let say Inkscape - compiz die and I got metacity again in all cases.

NO frezee, no nothing - fallback is OK.

But I must restart compiz each time with compiz --replace (untill next 20 minutes).
Sometime is enough to open a folder.

I think is not a big problem to solve.

Thank you for your bug report.
About compiz and Emerald : Did you install them from the officiel repositories ?

I do a little test to see what programs OR what else can broke Compiz so I restart Compiz with compiz --replace.

All OK but when I try to open a SVG file with Inkscape - my desktop do a short tremolo and compiz gone, metacity come.

This is the message from terminal :
Floating point exception (core dumped)

After that, I tried to see if Compiz crash launching other applications but I can't - Compiz behaviour was stable.
I only can crash Compiz doing a doubleclick on a svg file. Then Compiz crash and Inkscape don't open the file.

If I do this without Compiz started, Inkscape open the file without problems.

Trying to crash Compiz just launching Inkscape I obtained different results - sometime crash ..sometime not.

I'll attach the svg file here.

I forget to say Emerald was just installed but I don't use it at the testing moment. So, Emerald was no implied.

I don't use Trevino repo OR Amarath repo.

Only pure Gutsy repositories.

OUT OF TOPIC FOR 2 MINUTES => I need an indication about WHERE, or WHICH team I have to contact about the Compiz / Emerald tray launcher.

Last week I tried Fusion-Icon which was made until Tribe 5 release ( this mean that fusion-icon think compiz is not started by default ) so if someone try to put fusion-icon in tray - Gutsy at start will start Compiz - then Fusion-Icon will start Compiz again for the second time.
Gutsy by default don't install this window manager which is a loss.
Fusion-Icon is the perfect solution to set up Compiz and Emerald or to choose other window manager if U wanna play a game for example.

The only thing that keep me away from Fusion-Icon is he start compiz for the second time and I don't like all those flick's on my screen when GDM start (fusion-icon contain exec a command like compiz --replace & emerald --replace).

If this behaviour can be corrected Fusion-Icon MUST be included in original Compiz installation. It's a logical move to have this option at your click - not to search all time for Apperance->Desktop Effects->Normal Effects.

I am unable to reproduce this error. I can open that file with inkscape just fine. Does this open happen when you use emerald?

Nope, I just don't use Emerald - Emerald was just a nice try - works OK - but for me Compiz + Metacity borders is enough.
I have a pretty nice UI (Clearlooks + NuoveXT + T'ish Lively.

Compiz work OK - almost no CPU usage (1 - 5 percents with all effects) - but sometime when a window is created by a program Compiz just stop working.

this is the message : Floating point exception (core dumped)

I have a lots of extra gnome libraries (I use Cinelerra and Kdenlive) maybe something is wrong there. Anyway the results is unpredictable today I had no problems with Inkscape but each time I launch gFTP - just stop working.

Will be helpful for me to find HOW TO trace this crash.

Also, maybe this bug has some replications - maybe you will find someone with the same problem and maybe linking those bugs we will find an approach. I just don't have enough time to search on the Compiz bugs stack, but I can try to catch this error is someone can tell me HOW TO.

Well I've managed to reproduce this bug - in a "scientific manner".

I tested window behaviours when the Compiz crashed.
Is not about programs - I can stop Compiz using any aplication that can open a FULLSCREEN window.

For exmple Nautilus.

By default I "trained" my folders on the desktop to open their windows at 50% from desktop not full screen

Now I put a folder on fullscreen mode - I close that folder - and next time when I open this folder (Nautilus memorize last size and position of windows for each folder and for some applications) - Compiz gone.

Same things for other applications.
-> When in non fullscreen mode - ALL OK.
-> When any folder OR application was opened directly in fullscreen mode - Compiz die.

About bug behaviour
When I launch some programs - they wont open windows - they crash Compiz then stop.
After Compiz gone and Metacity come - Applications work normal ( open ..close ..etc ).

For the latest testing series - I used UNREDIRECT FULLSCREEN WINDOWS option from Advanced Desktop Effects Settings -> General Compiz Options -> General - but no better results.

I made I think 30 tests - with the same predictable (from now) behaviour.

I hope this will help

After last Compiz upgrade on 13 Sept. 2007

Checking for Xgl: not present.
Blacklisted 'ati' driver is in use
aborting and using fallback: /usr/bin/metacity

Well I don't use FGLRX at all indeed.
Blacklisted 'ati' driver was good enough yesterday. ...or, Gutsy put the fglrx driver by themself ? - let's check ..nope
the same hardware configuration but updated compiz wont work so I can't give other reports on this bug.

in general lines ---- this is not the expected behavior, after an upgrade - my suggestion is to prevent testing user community - hey we put something new inside that need XGL so install XGL first.
second big interior question is where I can obtain this blacklist ? maybe I'll buy other card to support Gutsy.

Back to the bug report -> Regarding my last post referring to FULLSCREEN WINDOWS - I do an experiment before Compiz upgrade.

I put XFCE Desktop.
Guess what ...
Compiz work perfect with XFCE - no problems - ans I was used exact the same themes from GNOME - ClearLooks and Nimbus.

Well from here I'm afraid I can't help more - I don't know If I can put my Compiz back without reinstall Gutsy - so I have to wait for next TRIBE.

Best wishes to all

OK, problem solved ..need to point now to Compiz Developers

The strange behavior for Fullscreen opened windows (Nautilus or other applications) was caused by a Compiz plugin named PLACE WINDOWS under WINDOWS MANAGEMENT SECTION.

This plugin has 4 possible states = 4 possible ways to put a window on desktop when this window is generated.

1 Centered
2 Smart
3 Maximize
4 Random

The subject of this bugreport is RANDOM mode.
When RANDOM mode is activated - this plugin try to calculate a random X and Y start points for the new generated window.
This is in oposition with the case when a window try to start in fullscreen mode.

I will try to note this to plugin owners - maybe this mode can be disabled for windows opened in fullscreen mode.
