Comment 3 for bug 83167

Update #2: installed all available updates today, including the revised 8.32.5 fglrx driver - no change in issue. Even more interesting is that gedit will not launch unless the system is booted without the network attached as listed above. Attempting to launch gedit after connecting network results in nothing (sudo), or a white, empty box (gksudo). In response to this, I installed leafpad, which works without issue no matter what state the machine is in.

Removed/purged all driver files and manually built 8.33.6 driver only to have the build fail. Launched ATI graphical installer, but this also failed.

Brought machine back up with Mesa drivers: still won't boot with net cable attached. Retested gedit failure: still present. Interesting: just launching gedit works fine, it's only when invoked via sudo or gksudo that the problem appears. Still no error messages.

Unknown what common linkages exist between network-manager, fglrx, & gedit.
