I presume this is a bit premature to judge the effect of this workaround, but this has solved multiple problems I was having:
- Random X crashes/hangs: It can now run safely with Beryl without me trying to make it crash (by openning many OpenGL windows simultaneously, resizing/max-minimizing, switching repeatedly to desktop/fullscreen mode).
- Switching to and from VT is no longer the problem.
- TV-Out is working nearly perfect (somehow I couldn't make my TV pans, albeit in Clone mode)
netllama, will you please investigate this option and possibly stickified this unique workaround when everything is cleared ?, it seems to work with several cards in GeForce Go family, but the others may take a shot.
