Compiz won't start after the 10.04 Beta 2 update

[Zachary Larsen]

Binary package hint: compiz

Compiz won't start after updating from Ubuntu 10.04 Beta 1 to Beta 2. The system attempts to initiate it when the command "compiz --replace" is run manually, but falls back to the default window manager after briefly flickering. When run from a terminal, "compiz --replace" returns the following:
Couldn't find a perfect decorator match; trying all decorators
Found no decorator to start
compiz (video) - Warn: No 8 bit GLX pixmap format, disabling YV12 image format

The package compiz and compiz-gnome were removed with the partial-upgrade.
Maybe thats the reason. I have the same problem now, but when trying to install these two packages again, Synaptic wants to remove metacity and ubuntu-desktop, so i didn't do it!

[Sven Bendel (ubuntudroid)]

I can confirm the problem, jango described.

[mrtwister (mrtwister)]

Same here. Nvidia current. Like Zachary I have also a Dell Latitude D820 notebook.

[Stefan Hammer (j-4-deactivatedaccount)]

I have an Thinkpad T400 with Intel GMA 4500MHD. So it is probably not
driver related.

[Pfanne (pfannenwender)]

I had the same problem.
I just did "apt-get update" and installed compiz-gnome.
Everything works fine again.

[mrtwister (mrtwister)]

Didn't synaptic wanted to remove metacity when installing compiz-gnome?

[Pfanne (pfannenwender)]

Nope,
nothing like that.
But then, I didn't use synaptic.

[greg (grigorig)]

Manually downloading and installing compiz-core, compiz-plugins and compiz-gnome should fix it in the meantime.

[Net-Zwerg (net-zwerch)]

Had the same Problem, "sudo aptitude install compiz-gnome" fixed it for me.

Synaptics indeed wanted to remove metycity and ubuntu-desktop.

[Bordi (borderlinedancer)]

Same problem...

but

apt-get update && apt-get install compiz-gnome -y

dosn't fixed it. :(
