I'm having trouble since I installed the newest kernel update. I only have one desktop. I unistalled compiz. Then I get the message 'you don't appear to have a window manager installed' I reinstalled compiz, but it gives me a misty screen, with the cube desktop. How do I set compiz to a default setting? Plain and simple? Where is the config file? This may have started when I clicked a box 'enable indirect rendering' just to see what happened. I have an nvidia 9200 card on an Asus laptop.

Failing that, how do I reinstall Fed 12 without wiping out my home directory? Thanks

logout
at the login screen, select gnome or KDE.
log back in.

this should load gnome or kde's window manager.
you may need to update your nvidia driver.

how did you uninstall compiz?
how did you reinstall it?

compiz settings are handled through System > Preferences > CompizConfig Settings Manager.
eg.

Thanks. I'm narrowing down the problem: it goes mad when I go to Applicatins>System Tools > Compiz Fusion Icon Then the screen goes white, nothing works. A restart, and I have a single desktop again, but the windows are not working properly: the frame stays the same as a non-selected window.

I need to reinstall Fed.

I unistalled and re-installed using yum.

I just tried to change the settings in Preferences>Compiz Settings Manager. I set the numbers of desktops to 8, disabled all effects. But the problem persists.

Addition: I created a new user. Things seem to work ok. I'm not going to touch compiz. But I think there must be a local setting which has gone haywire.

I'm also getting a problem in the boot message nvidia segmentation fault.

Enabling the nvidia driver: /etc/rc.d/init.d/functions: line 520: 1113 Segmentation fault "$@"

[FAILED]

here is the code from rc.d/init.d/functions. Anyone know what's wrong?
The line beginning action is line 520
# Run some action. Log its output.
action() {
local STRING rc

STRING=$1
echo -n "$STRING "
shift

rc=$?

}

There is no way to figure out what went wrong because you hae not been clear about what you have done. You are just giving hints and half-descriptions. Do not make us guess.
So? Have you reinstalled fedora?
What? fedora? compiz? Which yum command did you use - a meta-package, a component list, what? Show the actual commandline so I can see what you did - don't make me guess: I'll get it wrong.
You still get a misty screen with a cube desktop? (That is the problem you reported.)
What do you mean by "things seem to be OK" - what has gone right? You got a new user but with the misty stuff? Or the new user does not have 3D effects enabled? What?
If you have none of the desktop problems as the new user, then the setting contributing to the issue is local: yes ... but we know that because compiz setting are changed locally by users as a matter of principle: cannot have users changing setting for everyone can we? Look in /home/$USER for hidden files. You can probably work around your problem by copying the hidden files over to your old user.
Perhaps the driver problem is creating your compiz problem?
Reinstall the nvidia driver from RPMfusion. (1st link in post #2)

... from post #2:
Did you logout, explicitly select a different session, and log back in?
Did you update the nvidia driver by the instructions provided?

I unistalled compiz, not Fed. But that didn't solve the problem, I have a messed up system for the old user. I made a new user. The new user has multiple desktops and everything works. There must be a local compiz config file for the old user that is messed up.

As new user, I have not even tried to start compiz, (I need my laptop) I presume it has default x settings. I like compiz, but if it only causes probs, better leave it alone.

But if you know how to reinstall Fed without wiping out the home directory, let me know please.

It is common ot install fedora using the advanced partitioning (whatever they call it now) and create a separate partition for your home directory. Next time you need to install, go to advanced again, but tell the partitioner not to format the home partition - but to mount it at /home instead.

You can sort-of do that now - resize your root partition ta make some space, create a ext3 partition on the empty space, copy /home to it, then edit /etc/fstab so the new partition is mounted to /home on boot. Reboot.

There is not normally an issue with compiz in fedora. It is normally enabled by default. your's wasn't, probably because of your video card - have you updated its drivers yet?

In general, nvidia support tends to wander a bit because maintaining proprietary binary-only drivers is hard and nobody can help nvidia do it.

The main thing to remember when you are new is that you look for software first in your repositories - in fedora, that means using yum. you'll probably be happier with a gui for it - something like yum extender (su -c yum install yumex). This will let you browse the repos.

mjmwired has a good guide to fedora install and configuration.

Thanks, that's a good idea, to create a home partition. I'm just not sure how to get it to be mounted on boot. An entry in fstab?

I don't really want to do a reinstall, as I have lots of things installed, and it takes time. I'll stay with the new user, and wait on nvidia driver updates. The problem may go away.

Do you know where to look for the compiz conf settings? In xorg.conf?? They must be somewhere. I can then compare the new user with the old user, maybe see what's wrong.

The per-user compiz setting are in that users home directory in a hidden file ".compiz".
Cpying this one over to your old user may be all it takes.

You put an entry in fstab to mount partitions at boot, yes.
You should already have some in there to copy.

Thanks!

No worries - don't forget the thumbs-up button.

Problem: there is no .compiz file or directory in the new user account. I don't even want to start compiz as New User, or it might cause problems again.

How do I tell bash to display hidden files? I have cd-ed to /home/peter, but dir only displays the normal files. I can't see any .compiz

Solved the dir problem, this is the result:
