beaker, i don't think you understand what we are talking about. (forgive me if you do)
Maya was fully operatable under Gnome. I changed alt key mapping, so there's no limitation in viewport operation. Can move, tumble,dolly...
The probelm was, mouse pointer, which supposed to be shaped as 'black/red arrow' most of the time, changed to "x" mark.
Usually, it changes to x when you call marking menu by hitting space bar, but as soon as you release the space bar, pointer shape will be _back_to_red_again_. But not in Gnome enviroment, it never come back to red arrow. so you have to operate maya with 'x' shaped mouse pointer which bugged first poster and me.
I just went thru twice thoese threads you linked . but i couldn't find they are talking about this problem. If they do, Can you quote correspond lines for me?
If there's anything not clear, please let me know...
