enter image description here 2: Screen-ruler image: https://imgur.com/qpvIQTk.jpg

Ubuntu v. 18.04 LTS OS. Lately display weird, unusual partially greyed-out main-menu drop-down-items, concerning: „GParted“ and „Screen-ruler“ (Bildschirmlineal) applications.

At first all these drop-down-items were permanent visible. For details see two attached display-photo / images. IMGUR: takes only one photo

How to solve this? (Guessing: missing or broken third-party „theme-libs“)

  • What theme are you using? Have you tried to go back to the system's default theme? (Is it called Yaru on 18.04 too?) Do these problems show if you use the system's default theme? – Levente Feb 25 '21 at 01:24
  • Hallo Levente, thanks about your care. How do i find out what theme is used? How do i go back to the system default themes? – Linuxfreund Feb 25 '21 at 18:12
  • I am on 20.04, so I will have to guess what's it like on 18.04. I will guess you could use the Settings app for that. It has an Appearance item in the sidebar. It offers a choice between "Window colors", like Light, Standard, and Dark. This is the system-default theme, and its variants. (At least on 20.04.) So the normal Settings app will let you choose only this theme. If you have additional themes installed, they were probably/possibly enabled with the Gnome Tweaks app. With this app you can switch between all themes (including 3rd party themes) that are present on your system. – Levente Feb 25 '21 at 18:22
  • How do i find out by terminal command if Yaru or something else is in use? Sidebar Icon named: "KDE-Systemeinstellungen" and says Kubuntu is activ. – Linuxfreund Feb 25 '21 at 18:44
  • On 20.04 it's gsettings get org.gnome.desktop.interface gtk-theme – Levente Feb 25 '21 at 18:47
  • Oooohh KDE! I know nothing about KDE! :) Are you on Kubuntu? By all means put a KDE tag on your question. And also kubuntu, if that's your flavor. And also theme. – Levente Feb 25 '21 at 18:51
  • This is an other problem, some times ago my originally UBUNTU v. 18.04 OS installation start-screen changed into KUBUNTU from itself!. Terminal command says: "Ambiance" – Linuxfreund Feb 25 '21 at 18:56
  • Search for stories like "Ubuntu turned into PopOS" and "Ubuntu turned into Elementary OS". I think your story is pretty similar and will have a similar solution. This site had a few such threads in the past months; but try to search with external web search too, maybe it finds them easier. If you get stuck while de-KDE-ifying, post a new question specific to that. – Levente Feb 25 '21 at 19:19
  • Thanks so far as.- – Linuxfreund Feb 25 '21 at 19:25

My request to the developer of the „Screen-Ruler“ Mr. Ian Mcintosh: A fault concerning the context drop down menu comes up. All items in this drop down menu are visibly only in grey. Only when putting the cursor onto these items they become colored. The functions behind these items work well at all!

The developer answers 26.12.2020: „I think screenruler has totally normal menus.  Are the menus weird in any other app, or just screenruler?“ My answer: The same phenomenon happens elsewhere.

Reply from Mr. Mcintosh: „Hmm it sounds like you have a problem with your "theme" and it might not be related to screenruler at all! :D“
