Description Adam Jackson 2012-05-23 12:29:18 UTC

Field testing of SNA is hampered by the inability to switch between it and UXA at runtime, instead requiring a driver rebuild.  This means issues like bug #49721 are closed as WORKSFORME because SNA happens to work, even though SNA is not the default and does not rendering correctly enough for distributions to enable by default.

commit e45629135065d0cc73c285f8df35ab4e1d07c6dc
Author: Chris Wilson <chris@chris-wilson.co.uk>

    Allow runtime switching of AccelMethod between uxa/sna and even glamor
    
    Section "Device"
      Option "AccelMethod" "uxa/glamor/sna"
    EndSection
    
    The appropriate backend must also be enabled at compile time for the
    runtime option to be available (i.e. --enable-uxa (default) --enable-sna
    --enable-glamor)
