I recently got a Dell XPS 13 Developer edition running Ubuntu 13.04 (Intel Ivybridge Mobile driver) and have tried using pd-extended 0.43.4 64 on it. For the most part it runs fine. However, I've noticed that in some situations, such as an old patch not being able to find external abstractions, it causes the screen to go black and then log me out. This also happens in some patches when I try to type in the name of a new object on the canvas.
I'm not exactly sure what is causing this. I've attached a patch that I grabbed from the list which causes a restart when I try to type in a new object
Any help would be appreciated.
Antonio
Hi,
I noticed that on my computer too a few months back. I had the same problem with Audacity and Kicad (both wxwidgets apps).
For what I understand, this has been tracked down to a bug in the Intel driver in conjunction with a Xorg bug when using unaccelerated graphics. But I may be wrong.
So first, double check you are using hardware acceleration. I thought I was and I wasn't for months :).

How can I check this on Ubuntu 13.04? I don't appear to have any proprietary drivers installed but does that mean it's not using hardware acceleration?

Check in the Xorg.log file (on my computer it's /var/log/Xorg.0.log) for lines talking about acceleration and intel.
The driver is open source straight from Intel (thanks guys). The acceleration can be disabled for some reason.
Maybe there is also an advanced configuration panel somewhere.

It turns out I just needed to upgrade my intel graphics drivers, which is described here http://puredata.hurleur.com/sujet-9448-solved-crashes-server
Thanks for the hardware acceleration tip ;-)
