How do I restore or recreate it?
Hi, please elaborate your question more: like which Jetson device and what version of L4T you are using,
or we cannot help you given such a vague question.
Also try if you can launch it through terminal:
$ gnome-control-center

Jetson TX2 Developer Kit
Ubuntu 18.04(L4T)
JETPACK 5.1.1
You mean the icon disappeared from the application launcher, right?
Do you encounter similar problem with any other apps, or only Setting?
If you can still launch Setting with terminal as shown in my previous reply,
you may manually add it back using tricks like this.
Or if it not the case, do a backup first and re-flash the board to see if it helps.
If you flashed JetPack 5.x+ on a TX2, then this is why it failed. TX2 is not compatible with those newer releases. You have to reinstall using JetPack 4.x. You can clone first if you have something you want to save.
I forgot though, you can start with “sdkmanager --archivedversions” to see some older release; if you can run 5.1.1 as a 4.x series, then that should work.
To flash the whole system again?
I just didn’t know why sdkmanager auto update the jetpack if the newer version is not compatible with TX2?
Hi,
What is the exact question here? TX2 will not be upgraded to jp5.x. There is totally no support for jp5 on TX2 at all.
What icon? On jetson or on your host machine?
It is weird. I will check it again.
The “Setting” icon was on the sidebar of L4T(TX2) but now disappeared.
Yes. It was on the application launcher. I can still use the setting from the drop-down menu and the functions are almost the same but the appearance is different. I prefer using the “setting” on the sidebar launcher.
I mixed up the versions of sdkmanager and jetpack. Actually, the sdkmanager is 5.1.1 and the jetpack 4.6.1.

So all you should do to is to find it from the application launcher, right click on it, select “Add to Favorites”, and it will be added to the sidebar.

$ gnome-control-center cannot bring back the setting icon.
Check this post to re-install it and see if it helps:
Thank you! It works. Actually, the disappeared icon is “System Setting”(now restored) but not “Setting”. They are somewhat different
