Ubuntu Panel Menu Bar Applet Loses Transparency / KDE affects Gnome
At one point or another during all of the customizing I’ve been doing since I installed Ubuntu, my panel’s Menu Bar applet lost its transparency:
Even the Notification Area’s grab handle lost its transparency. I figured there may be something wrong with the panel itself, so I created a brand new one, added the Menu Bar applet, set the transparency, and yet again it wasn’t working.
I decided to create a brand new user account and log in to that to see if the transparency worked. And it worked! Obviously, this was a user-specific issue. I didn’t want to just start from scratch with a new user; I wanted to solve this.
On another note, I also noticed that when I changed my theme, the colors of most controls wouldn’t change. For example, when going through menus, the menu selection color was still the same and I couldn’t change it no matter what. Also, Amarok’s color theme wouldn’t change either. It was the same color as the old theme.
Then it dawned on me… Amarok is a KDE application. I have the KDE environment installed and that was my main environment for a while and I had customized it a lot. Could this be a KDE-affecting-Gnome issue? Is it even possible? But what would explain the menus and other Gnome components not changing colors?
I did some more research online and checked through a lot of my settings and files.
I finally found the culprit:
Under KDE, I had set the option of using my KDE style in all GTK applications, which – unbeknownst to me at the time – meant in all environments. I found this out in this post.
To fix it, I had to sign out of my Gnome Desktop and sign back into a KDE session. Then I went to [ KDE Menu > System Settings > Appearance > GTK Styles and Fonts ] and changed the “Use my KDE style in GTK applications” to “Use another style” and chose “Human” as the style.
I logged off from my KDE desktop, logged back in to my Gnome desktop, and I noticed a difference right away. It seemed the desktop loaded much faster and my controls were in their correct color.
I set the transparency on my panel and I was back to normal!
Thank god for a little research, Google, and the Ubuntu Forums, I didn’t have to resort to re-installing Ubuntu… which I was planning to do. It was much more rewarding to me, less time-consuming, and a good learning process than having to start from scratch.
