Bug Description

We are staging xserver 1.11 for ubuntu 12.04 in xorg-edgers and don't currently have gesture/multitouch support in X, which means utouch does not work. Compiz segfaults when starting unity 100% of the time in this setup (see bt-full.txt attachment). According to Chase Douglas, geis_init returns NULL like it should because there is no utouch instance, but unity is not checking this situation. The multitouch/gesture stack is specific to Ubuntu for now, meaning this same situation will be hit by anyone else trying to ship unity.

Workaround if you got this bug after installing xorg-edgers ppa into Ubuntu 11.10: before system starts choose recovery mode in grub, then choose to continue normal boot, login into system, and type into terminal:
sudo ppa-purge xorg-edgers
After reboot Unity will work normally.

It looks like this revision of unity will fix it?

Is there nothing further on this? I imagine it will become critical for Precise fairly soon.

For now I just disabled geis from unity completely with http://sarvatt.com/downloads/patches/byegeis.patch in xorg-edgers, it wont affect precise because we can't upload a newer xserver if it doesn't have these crazy multitouch backport patches because people will blame X and 100+ packages built against the new abi will have to be reverted..

@Robert

Thanks for the work around, it now works. I am wondering what happens when there is an upgrade in Unity or Compiz, will the version of Unity in xorg-edgers be upgraded too? I am expecting some upgrades in Unity and Compiz as there are a few outstanding bugs in those packages and not sure will Unity be broken again.

Thanks.

not sure if this is related to the multi touch portion being removed or not but when I am using this PPA my touch pad on my ASUS u43F goes crazy. It becomes supper sensitive making it very difficult to click on anything.

You aren't the first person to mention that with newer synaptics snapshots in there. Can you file a new bug with ubuntu-bug xserver-xorg-input-synaptics about it and possibly also attach a /var/log/Xorg.0.log from a boot without edgers to compare?

Unity commit 1728 doesn't fully fix the issue because _root_instance is not always initialized properly. Ideally, it should be initialized to nullptr in the constructor.

Assigning to Mirco to finish the fix.

Is the fix going to ever land in oneiric-updates? unity is still at version 4.28.0 there:
