Bug 309401

evolution - hidden border - top-left

compiz-0.5.2-13.6b86f3.fc8

now i can move the window once again with [alt]+[mouse]

if i open some applications eg. thunderbird, firefox, evolution, ...
the top-border is hidden under the  top-gnome-panel

sometimes firefox does remeber his last position on the desktop iand s not
hidden in the top-left corner.


hardware:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS,
943/940GML Express Integrated Graphics Controller (rev 03)
driver:
xorg-driver "i810"  because "intel" does not work at the moment.

compiz-0.6.0-1.fc8

the top-panel is now visible for a short time while the logon then it disappers
until i click on the desktop. the problem is still the same with new windows


without "desktop effects" the top-panel is ok.

Comments #1 #2 and #3 dont' reflect my current experience and the description of
this bug.  I get no window borders or title bars at all--it isn't that they are
hidden under the panel.  It acts as if no window manager is running at all.  All
my existing windows lose their decorations.  The decorations come back when I
turn off Desktop Effects.

I've since updated to compiz-0.6.0-1.fc8, and the same problem remains.  I'm
using the radeon driver on ATI FireGL Mobility T2.  I looked into this further
and if I run "compiz --replace" from a terminal I get these errors:

>compiz --replace
compiz (core) - Fatal: GLX_EXT_texture_from_pixmap is missing
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

glxinfo showing GLX_EXT_texture_from_pixmap

The GLX_EXT_texture_from_pixmap error doesn't make sense.  Here is my glxinfo
showing that I do have GLX_EXT_texture_from_pixmap available as both a server
and client glx extension.

Is this maybe a Mesa or radeon driver bug?

what happens when you unset your active_plugins with `gconftool-2` or
`gconf-editor` ?


$ gconftool-2 --unset /apps/compiz/general/allscreens/options/active_plugins


$ gconftool-2 -g /apps/compiz/general/allscreens/options/active_plugins

[glib,gconf,dbus,png,svg,video,screenshot,decoration,clone,place,fade,minimize,move,resize,switcher,scale,plane]

I had the same problem with compiz-0.6.2-2.fc8, but the above fixes it. Thanks.

On a new user account, compiz is working fine now.

On my existing user account, I had to unset active_plugins per Comment #6, and
it is now working too.

Are gconf settings not upgraded/migrated automatically?  Seems like a bad idea
since we support upgrading Fedora from one release to another.

Changing version to '9' as part of upcoming Fedora 9 GA.
More information and reason for this action is here:
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

For me removing the ~/.gconf directory solved the problem. There may be some old
data in there that causes the problem.

X configuration file

FWIW, I see this behavior with Fedora 10, using compiz:

compiz-0.7.8-4.fc10.i386


Strangely enough, it hasn't always happened.  Everything was working fine
with desktop effects enabled, until a few days ago.  Not sure if a recent
update broke this of what, but it's consistent now: desktop effects enabled =
no window decoration.

Attaching my xorg.conf file in case it may be helpful.   See 

https://bugzilla.redhat.com/attachment.cgi?id=331345

happened here too, but i was playing with a new videocard and ccsm.

iirc this steps solved it:
1; disable desktop effects
2; logout, login  (or reboot)
3; unset  "apps/compiz/general/allscreens/options/active_plugins"
with `gconf-editor` or `gconftool-2`
4; enable desktop effects
5; check the settings for desktop effects and/or ccsm


$ gconftool-2 -g /apps/compiz/general/allscreens/options/active_plugins
[core,glib,gconf,dbus,png,svg,video,screenshot,decoration,wobbly,clone,place,fade,minimize,cube,rotate,zoom,move,resize,switcher,scale,obs]

Trying that didn't alleviate the problem for me.  

[prhodes@voyager ~]$ gconftool-2 -g /apps/compiz/general/allscreens/options/active_plugins

[core,glib,gconf,dbus,png,svg,video,screenshot,decoration,clone,place,fade,minimize,move,resize,switcher,scale,wall,obs]


And I still lose the window decoration if I enable desktop effects.

Also, starting X as a new user, which some people have reported as a workaround for this problem - didn't help either, FWIW.

FWIW, today's batch of updates brought in a new compiz:

compiz-0.7.8-7.fc10.i386

But the same problem still exists.

This message is a reminder that Fedora 9 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 9.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '9'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 9's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 9 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
