[Bug 1021733] Re: Complete the Additional Drivers implementation

[Mathieu Trudel-Lapierre]

apt-daemon tends to die sometimes, after multiple install/removes have been done in succession:
Traceback (most recent call last):
  File "/home/mtrudel/Public/software-properties/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 1017, in on_driver_changes_apply

It seems that the daemon died.

Definitely something to investigate.

Title:
  Complete the Additional Drivers implementation

Status in “software-properties” package in Ubuntu:
  Triaged

Bug description:
  I've started implementing the design in
  https://wiki.ubuntu.com/SoftwareAndUpdatesSettings#drivers ; devices
  can be listed on systems that require binary drivers, and the new tab
  is there with the basic UI bits.

  What's left to be done:
   - hook up signals for Apply
    - Might be more efficiently done as two steps: when selections change, list the changes, then apply the list of changed packages as a batch in Apply.
   - Remove the Revert button and make sure the "window" Revert button works (hook up signals to revert changes, clear cache, etc.)
   - Add the progress bar when Apply is running, replacing the "No proprietary..." label.
   - Testing, testing, testing.
