Ubuntu 15.04 black window border

Question

I just updated to ubuntu 15.04 and all my windows have a black border.

Is there a way to fix this?

Answer 1

I had a similar problem with the black borders after upgrading to 15.04... i switched from Nvidia 340 to 346 and back and ran the following

dconf reset -f /org/compiz/
setsid unity

You might try just running the latter.

Answer 2

I always have the same problem after resuming from suspend. I've found three different solutions.

- Change the appearance theme to something else and back from the command line. Eg. if your current theme is "Ambiance":

    gsettings set org.gnome.desktop.interface gtk-theme "Radiance";
    gsettings set org.gnome.desktop.interface gtk-theme "Ambiance";

[edit - the above only fixes currently open windows.]

• Run unity --replace from a terminal or the Run Command Prompt (Alt + F2). This will reinitialize Unity, which will take a few seconds, but you shouldn't lose any work.

  

• Install and run CompizConfig Settings Manager (sudo apt-get install compizconfig-settings-manager; ccsm;). Open the settings for "Ubuntu Unity Plugin", click the "Decorations" tab, then check and uncheck "Override Theme Settings". This way requires more work, but doesn't involve your desktop disappearing for a few seconds.
