I'd like some help to fix another unity issue. After last update, my system broke. For example, when I execute a 'ls' command, the screen breaks and does not show anything. Sometimes, just the beggining is shown.

How can I fix it?

I don't want use another X, for now...

    Hello, I get this issue fixed! When I was trying to re-install my drivers with commands: sudo add-apt-repository ppa:sarvatt/intel-sna && sudo apt-get update && sudo apt-get dist-upgrade -y sudo add-apt-repository ppa:xorg-edgers/ppa && sudo apt-get update && sudo apt-get dist-upgrade -y A message was showed to me, so I did follow the tip and create a xorg.conf with with content: Section "Device" Identifier "intel" Driver "intel" Option "AccelMethotd" "uxa" EndSection Just it! I hope it helps! Thanks

Before removing Compiz you might wanto to try and reset it

1.Press Alt + ctrl + F1

2.Login using your username and password

3.Reset compiz by executing gconftool-2 --recursive-unset /apps/compiz-1

4.Reset unity , by executing unity --reset

5.Optionally you can reset launcher icons by executing unity --reset-icons

6.Press Alt + ctrl + F7 to get back to login screen. However I recommend a restart by executing sudo reboot. Let us know if it worked.

Cerdits to Web-E

To remove compiz and compiz packages type this in a terminal:

sudo apt-get purge compiz compiz-plugins-main-default libcompizconfig0

Warning: Removing compiz also removes the packages unity & ubuntu-desktop.

Warning: Removing libcompizconfig0 also removes ubuntu-tweak.

Thus you will lose the ability to log into the unity or unity-2d desktops.

You can try Ubuntu Gnome. It doesn't use Compiz and still has as much, of not more eye candy as Ubuntu.

I have a multi boot system, and Ubuntu Gnome is one of them.


Instead of trying to delete compiz, which will have many dependencies issues with Unity and Gnome etc, how about just going ahead to install other Window Manager? The last time I tried to uninstall / delete Unity/compiz, I ended having to reinstall the entire OS.

For example: Xubuntu:

apt-get install xubuntu-desktop.

Or you can try i3, awesome, lxde etc.

And then at the login screen, select the appropriate windows manager - making sure you avoid Gnome, Unity or compiz.

After logging in, "ps -ef" and you can easily verify that compiz is not running.
