Comment 14 for bug 272474

I think we have two different bugs discussed here. The original problem of immediate silent failure occurs on a stock intrepid desktop CD with an nVidia quadro board with a recommended nvidia-177 driver (nothing to do with the legacy driver issue from bug 288662). After using update manager to do a check for updates (but not installing any of them) jockey-gtk -e xorg:nvidia-177 runs for about 10 seconds then returns the following dbus error:

Traceback (most recent call last):
  File "/usr/bin/jockey-gtk", line 377, in <module>
    sys.exit(u.run())
  File "/usr/lib/python2.5/site-packages/jockey/ui.py", line 395, in run

nwadmin@nwadmin-laptop:~$ jockey-gtk -l
xorg:nvidia-173 - NVIDIA accelerated graphics driver (version 173) (Proprietary, Disabled, Not in use)
kmod:wl - Broadcom STA wireless driver (Proprietary, Enabled, In use)
xorg:nvidia-177 - NVIDIA accelerated graphics driver (version 177) (Proprietary, Enabled, Not in use)

I had jockey-backend running in a separate window as suggested above and about 30 seconds after jockey-gtk crashed the backend kicked to life and apparently installed the driver successfully.

It seems to me that the silent failure is related to a repository/package problem on the CD. The dbus failure might be a download timeout.
