unity_support_test was rewritten from scratch in nux 0.9.38, so your crash should not exists anymore. Can you reproduce it with the latest packages in natty?

[qamelian (carl-godfrey)]

I'm not able to test it at the moment, as I can no longer get unity nor compiz to work on this netbook.

[qamelian (carl-godfrey)]

I just did a fresh re-install of 11.04 and completed all updates. The problem does appear to be resolved.

[Omer Akram (om26er)]

given the fact that unity_support_test was re-written and also a confirmation for the issue not happening anymore, I am closing this bug as fixed, if someone still faces this same issue please let us know or even report a new crash so that we actually know the new issue is the same as this one.

[wayne law (lawreway)]

U*sing computer janitor when the report thing came up to say there was a problem . I had just logged on.

[Asylum (davidjellison)]

Is still occurring.. fresh upgrade from 10.10 dell gx620 with ATI dual head graphics card. added flgrx for HW GL in unity, reboot then this..

[Didier Roche-Tolomelli (didrocks)]

@Jay: see bug #767504, seems it regressed.

(subscribing loic as well on this bug report)

This is a dup of #747286 which has been marked as invalid. See https://bugs.launchpad.net/unity/+bug/747286/comments/5.

[Loïc Molinari (loic.molinari)]

Didier, Sébastien: Feel free to mark it as duplicate it if you agree with my previous comment.

[Timo Witte (spacefish)]

i have that problem with newest oneiric updates today, after installing fglrx, but could also be related to updated libunity

[Braiam Peguero (braiampe)]

It seems that installing fglrx trigger the bug. While I don't have fglrx all work ok; after the installation and reboot apport shows the bug report. I unistalled fglrx and everything runs normal.
