Huh... This is weird. Does vsync work for other programs?
try this as a normal user:
__GL_SYNC_TO_VBLANK=1 glxgears -printfps
It should print exactly the vertical refresh rate of your monitor. If it
doesn't, there's probably something wrong with your driver setup.
Just using -g by itself doesn't cause the CPU to
race, but it
can easily lock things up. (The keyboard locks up, the display
freezes, but the mouse still works) SDL mode is more stable and
doesn't seem to use the CPU any more than the OpenGL mode.
I don't mean to shift the blame on others ;) But this sounds a lot like a
buggy driver. I too have seen one or two complete lockups while resizing
the jack_oscrolloscope window. I guess that's what you get for using a
binary driver on a -rt kernel it wasn't made for...
