John & Will,
I made the change in XFreeConfig-4 that said John and, efectively, full
screen games, like pingus, run again (remember that pingus doesn't need
3d-acceleration).
The conclusion of John is true:
At least for Vodoo3 3000, DRI has a bug and switching resolution is controled
but this module; if you try to change resolutions or a game or other type of
aplication try to do that, doesn't matter if they use or not 3d acceleration,
DRI make the action and crashes X.
I have posted a bug report to XFree86, I hope they will work on the problem.
I will post in the expert list any comments that the XFree86 team sent to me
about this subject (I hope a patch or so on).
Note for the person of the mandrake team in charge of the X: could you check
that and also communicate to the Xfree86 team, I am sure they will work
faster if they know that Mandrake is also interested in the problem. :-)
Thanks.
See you soon, I hope wit good news
