Yes, the display size is the problem. Currently the minimum supported display size is 1536x960.
I am planning to add support for smaller resolutions in the near future. In the meantime, I hope you can get your hands on a bigger monitor!
My biggest monitor is a 19 inch one. With a little luck, I can reach 1536x960. But I'm not 100% sure it will be the case. I'll wait for the revised version with smaller resolution.
Done. Try now.
It works really better now. Thanks a lot!
Amazing to see it works natively on Linux :)
Cool!
