xorg-x11-server/u_vesa-Add-VBEDPMSGetCapabilities-VBEDPMSGet.patch
Stefan Dirsch 540300e204 - Update to version 21.1.0 
* The meson support is now fully mature. While autotools support
    will still be kept for this release series, it will be dropped
    afterwards.
  * Glamor support for Xvfb.
  * Variable refresh rate support in the modesetting driver.
  * XInput 2.4 support which adds touchpad gestures.
  * DMX DDX has been removed.
  * X server now correctly reports display DPI in more cases. This
    may affect rendering of client applications that have their own
    workarounds for hi-DPI screens.
  * A large number of small features and various bug fixes.
- updated xorg-server-provides
- supersedes patches
  * U_Fix-segfault-on-probing-a-non-PCI-platform-device-on.patch
  * U_dix-window-Use-ConfigureWindow-instead-of-MoveWindow.patch
  * U_glamor_egl-Reject-OpenGL-2.1-early-on.patch
  * u_render-Cast-color-masks-to-unsigned-long-before-shifting-them.patch
- refreshed patches
  * N_fix-dpi-values.diff
  * N_zap_warning_xserver.diff
  * u_modesetting-Fix-dirty-updates-for-sw-rotation.patch
  * u_randr-Do-not-crash-if-slave-screen-does-not-have-pro.patch
  * u_vesa-Add-VBEDPMSGetCapabilities-VBEDPMSGet.patch
- disabled n_xserver-optimus-autoconfig-hack.patch, which I believe is 
  superseded by:
  commit 078277e4d92f05a90c4715d61b89b9d9d38d68ea
