Description Fabio Pedretti 2008-12-24 02:18:55 UTC
1) the man page should say that disabling DRI also disable EXA Composite (RENDER acceleration) and AIGLX. Also it would be nice if that option also says why DRI is not enabled by default (stability?).

2) Option "ScaleType" documentation in the man page:
a) the "ScaleType" option appears to work not only for "Sets the scaling mode for laptop flat panels when used together with an external screen." but also when the requested screen size is different than the real screen size, but this is not clear on the man page.
Also:
b) "center means not to scale but center the image on the panel i.e. apply a
black frame around the image on the panel in case the panel
resolution is lower than the one of the external display."
here "in case the panel resolution is lower than the one of the external
display." should be changed to "if the resolution of the external
display is lower than the panel resolution." (the same of the "none" mode).
c) the difference between "default" and "none"/"center" is not very clear to
me; are "none"/"center" supposed to modify aspect ratio?
d) the "scale_keep_aspect_ratio" comment is not very clear.

We still have stability issues enabling 3D and 2D accel at the same time, that's also why DRI is still disabled by default.

Agreed. Rewording patches welcome.

Fixed.
