I'm using Acer TimelineX from beginning of using 12.04, Compiz is crashing more than twice daily. Up to today I've been trying to solve this problem by:

  1. Using another driver and graphic card.
  2. Using newest kernel and Xorg from Quantal backports.
  3. Resetting Compiz settings and whole profile.
  4. Changing Alt+Tab button bindings (I've readed that can be related).

What can I do more to resolve this issue?

I had these and other problems in compiz. You can find a bug report here. In short, the solution to that particular bug was to install an alternative, older version of the packages:

sudo apt-add-repository ppa:vanvugt/compiz-preproposed
sudo apt-get update
sudo apt-get install compiz=1: compiz-core=1: compiz-gnome=1: compiz-plugins=1: compiz-plugins=1: compiz-plugins-default=1: libdecoration0=1:

Restart compiz:

compiz --replace &

If that does not work better for you, the packages will be replaced during the next system update. Or just do

apt-get update
apt-get dist-upgrade

If, however, you have better experience with that older package (that was my case), you can make the change more permanent ("pin" the package at a certain version). For this, install synaptic:

apt-get install synaptic

Synaptic is an alternate package manager that also allows to pin the packages.

Alternatively, you can run:

{ echo compiz hold ; echo compiz-core hold ; echo compiz-plugins hold ; echo compiz-gnome hold ; echo compiz-plugins-default hold ; echo libdecoration0 hold ; } | sudo dpkg --set-selections

Solved by disabling HUD! – qMic Aug 29 '12 at 12:28
Compiz downgrade also helped in some situations. Now i have stable system at last. – qMic Aug 30 '12 at 0:07
