Tise hasn't been ported to Linux. I doubt that it will work under Wine
or other emulator. Technically it is possible to port Tise to Linux,
but I'm going to do this only if there is enough interest and support
from the community for this project. There are alternative methods to
type Tibetan in Linux, for example, using xkb capabilities
(Tibetan/Dzongkha layout by Chris Fynn), unfortunately, it's not EWTS.
Hopefully rendering engine for Tibetan opentype font is mature enough,
at least for KDE/Qt and Gnome, but I'd prefer to hear more about that
from other experts.
Thanks a lot for your answer.
So I gone have to stay with a dual boot because I do not have the tech capacity to get into the systeme.
BUT if one day some wizard can do something it would be marvellous.
All the best
