I'm using Ubuntu 12.04 with LXDE desktop environment.

When I use the normal Ubuntu desktop, everything is normal. When I'm using LXDE however, the bar with all opened files is black. You can see what I mean here:

I think I have found a solution that works. I changed the LXDE theme to Radiance using lxappearance. Gedit has no black bars now.

The problem seems to be related to the LXDE themes not being GTK 3 compatible. There is some advice which will work around the problem and relevant links to more details here:

Since this didn't have good answers here and I was having the same problem in XFCE. I asked a very similar question on AskUbuntu

The fix is as simple as choosing a different theme from the xfce4-appearance-settings dialog available from the main menu under "Settings" -> "Appearance". In LXDE the way to change themes is with the lxappearance command as codefx states in his answer.

The "Raleigh" and "Industrial" themes have this problem. Many others such as "Greybird", "Orion", and "Radiance" do not.

Here is the problem fixed running with the "Orion" theme:

  • This method works, however the gui might be different (at least on my version). In the main menu: select preferences/customize look and feel. The tab is called widget instead of style. – Robin Manoli Dec 12 '14 at 09:49
