* 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- disabled n_xserver-optimus-autoconfig-hack.patch, which I believe is superseded by: commit 078277e4d92f05a90c4715d61b89b9d9d38d68ea Author: Dave Airlie <airlied@redhat.com> Date: Fri Aug 17 09:49:24 2012 +1000 xf86: autobind GPUs to the screen - added pkgconfig(libxcvt) - cvt binary moved to libxcvt0 package OBS-URL: https://build.opensuse.org/package/show/X11:XOrg/xorg-x11-server?expand=0&rev=804
