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 PD mailing list which causes a restart when I try to type in a new object.
Any help would be appreciated.
