I'm quite confused and not sure how to exactly describe the issue, but I'll start with the statement that everything was fine for over a week (since I actually started using Ubuntu) until 30 minutes ago.
When I started Gimp, it showed up on the launcher bar, but it wasn't responding at all. The launcher looks as below:
You can see a sort of empty arrow next to Gimp. When I click it nothing happens,
when I press Ctrl+W it's not brought to front. I've tried reinstalling it, but that didn't help.
Does anyone know how to fix this problem?
Best Answer
The application is definitely running, and probably correctly.
There are a few possibilities:
Gimp
is running on one of your other workspaces / viewports.In the first case, either disconnect the screen or switch it on to see the application window. In the second case, navigate through the other workspaces with the keys Ctrl+Alt+ up/down/left/right arrow keys.
Note
In some occasions, after unplugging a second monitor, the monitor still appears as a "phantom" monitor in System Settings > Displays, causing the same issues as above. In that case, switching it off in display settings should solve the issues.
