Ubuntu 16.04系统Unity栏Files窗口无法打开求助

Hey there, sorry to hear your new System76 laptop's Unity Files launcher is acting up—let's walk through some tried-and-true fixes to get it working again. Since other launchers are fine, this is likely a localized issue with Nautilus (the underlying file manager) or Unity's launcher configuration.

Step 1: Restart the Nautilus Process #

First, let's kill any hung Nautilus instances and restart it. This is the simplest fix and often works:

1. Open a terminal with Ctrl+Alt+T
2. Run this command to quit Nautilus:

   nautilus -q
   

3. Then launch it again in the background:

   nautilus &
   

Now try clicking the Files icon again—if it was just a stuck process, this should resolve it.

Step 2: Reset Unity Launcher Configuration #

If restarting Nautilus doesn't help, the launcher's shortcut for Files might have become corrupted. Reset the launcher settings with:

unity-launcher --reset

After running this, log out and back in to apply the changes.

Step 3: Reset Nautilus User Configuration #

Corrupted user settings for Nautilus can also cause launcher issues. Let's back up your current config and start fresh:

1. Back up the existing config folder:

   mv ~/.config/nautilus ~/.config/nautilus.bak
   

2. Log out and log back in—this will generate a new, clean Nautilus configuration.
   (You can restore the backup later if this doesn't work by running mv ~/.config/nautilus.bak ~/.config/nautilus)

Step 4: Reset Compiz (Unity's Window Manager) #

Unity relies on Compiz for its interface, so a misconfigured Compiz setting could be the culprit. Reset Compiz and restart Unity:

1. Reset Compiz settings:

   dconf reset -f /org/compiz/
   

2. Restart Unity immediately after:

   setsid unity
   

Wait a few seconds for Unity to reload, then test the Files icon.

Step 5: Reinstall Nautilus and Unity Packages #

If all else fails, there might be corrupted system files. Reinstall the core packages:

sudo apt update && sudo apt install --reinstall nautilus unity unity-desktop

Once the reinstall finishes, restart your laptop and check if the launcher works.
