Uwe Brauer scripsit:
Ah yes, that's a problem. Please install
"equivs", then build a
dummy gtk-qt-engine-trinity package and install that ober your
current package:
I finally found a working solution
1. Goto to the (trinity) control center (maybe ubuntu specific)
2. Goto Appearance, deactivate use my TDE style in GTK2/3 applications.
3. Delete in .conf the geogebra directory
4. Restart geogebra
5. DONE.
Thanks very much for you help and Slavek whose comment I did not
understand at first.
