xorg-x11-server/xserver-1.3.0-no-pseudocolor-composite.patch
Adam Jackson 115cc5d8ad * Mon Apr 09 2007 Adam Jackson <ajax@redhat.com> 1.2.99.905-2
- xserver-1.3.0-pci-bus-count.patch: Allocate the PCI bus array dynamically,
  so as not to run off the end of it.
- xserver-1.3.0-mmap-failure-check.patch: Check for failure when mmap'ing
  bus memory. (#234073)
- xserver-1.3.0-rom-search.patch: Look for the sysfs ROM file in the (flat)
  /sys/bus/pci/devices tree, instead of the (bus-topological) /sys/devices,
  so we don't fail to find ROMs merely because they're behind a bridge.
- xserver-1.3.0-no-pseudocolor-composite.patch: Refuse to initialize
  Composite when Render is missing or when the root window is using
  a pseudocolor visual. (#217388)
- xserver-1.3.0-xnest-exposures.patch: Fix Motif app redraw in Xnest. (#229350)
