no icon in taskbar raspberry pi

[trevorjharris]

I logged in locally and ran startx. The desktop icon was visible but nothing on the task bar.
I then ran starti and got the following in jminim.log

I am away from home and can't try this at the moment. On my Pi3, I have used raspi-config to automatically start the desktop on boot and I don't see this problem. Can you try doing this as a test to see if it fixes the problem?

[trevorjharris]

Tried this and it did not fix the problem.

[simoncn]

Are you logging in as the default pi user? Did you install MinimServer as this user and did you use this user to run setup (without sudo)?

[trevorjharris]

I have solved the issue. I must have installed it as root at some time as it was a permissions problem.
I reinstalled as pi and all worked ok.

Sorry to have bothered you

[simoncn]

Thanls for letting me know. This will be useful if anyone else has the same problem.

[timster]

Not quite the same problem, but the Minim icon has disappeared from my QNAP's main screen. Shortcuts are on the login screen, but no matter if I toggle it on/off or all users/admin user only, it refuses to show.
Same problem on a different system perhaps?

[simoncn]

Definitely not the same problem. Please start a new thread to discuss this.

[trevorjharris]

Ah!! I thought I solved this but I think I have identified a problem. It seems I can only get the icon in the taskbar if only one desktop is running. I use 3 ways of connecting to the desktop console, xrdb and nomachine. The first desktop I start is ok but subsequent desktops dont not display in the taskbar. Eg if I start with the console it is ok. If I now loging with xrdb it will not display in the xrdb desktop. If I now log out of the console I can double click on the xrdb icon and the icon in the task bar will appear and so on..... So it seems minimserver interface can only work on one desktop at a time. Might explane I was getting so confused about this problem. I guess for most people it would not be an issue.

[simoncn]

MinimServer can only display one taskbar icon at a time. If you have a taskbar icon displayed and then start a second desktop, the second desktop won't show a taskbar icon.

I understand that this is an issue for users who use multiple desktops at the same time and I will look into whether it would be possible to remove this limitation.
