Hi, does this still happen with Oneiric? We have made a bunch of changes to unity_support_test and so it would be great to test again. Marking as incomplete pending some info!

[Oded Arbel (oded-geek)]

I get this constantly in Oneiric, using normal log in - without NX.

[Neil J. Patel (njpatel)]

@oded Does apport let you report the crash? We need an updated stack trace to be able to fix it and the one in this bug is pretty old.

[David Barth (dbarth)]

This bug was reported on a development snapshot of Unity but lacks elements for it to be actionable:
- there seems to be no reports of further occurences of the issue
- the bug cannot be reproduced reliably
- the information provided is not sufficient to track down the issue to a particular programming error.
Could you please check if this issue is present in the current version, and if it is reopen the bug to a NEW status.

[Jay Taoko (jaytaoko)]

This is happening on a Radeon 9600. Which is pretty old GPU. Please run "/usr/lib/nux/unity_support_test -p" and report what you get. Also try on Ubuntu Oneiric Beta 2 if possible.

[Jay Taoko (jaytaoko)]

I have tested a Radeon 9800 which is of the same familly has the Mobility Radeon 9600 M10 reported in this bug.
The Radeon 9800 runs Unity 3D correctly and unity_support_test does not crash. I haven't tested this bug in the NX environment as I am not able to do so.
I will mark this bug as fix released. Re-open if the problem still occurs.

Status changed to 'Confirmed' because the bug affects multiple users.
