Well, the problem is that when I press B to make a border select or a circle select (B pressed twice) it doesn’t updates at real time…i can select but the circle or rectangle does not follow my mouse, only when i have the LMB pressed…dont know if you understand what i mean…
I really do not know what is happening, maybe is just a mishap on that version of your OS or kind of certain incompatibility of blender + ubuntu. it is the first time that you install blender on ubuntu? or it happened recently, (your problem)… try reinstalling it… that’s what i would do… or install a newer or older version of blender to see where’s the bug, by the way i think that ‘B’ is for “Box select” not “border” well, it is irrelevant…
This looks like a 4 year old thread someone zombied, but for what it’s worth, I’m using Compiz now (successor to Beryl) with Blender 2.49 on Ubuntu and all is well, even with all the 3D desktop effects turned on. It’s actually pretty nice to have it running in its own side of the desktop cube while other surfaces have coding stuff and whatever on them.
