Всем доброго Суть: На p9/branch и выше, на графике Интел Broadwell GT2 (gen8),с драйвером intel_drv, акселерация необратимо сваливается в UXA с серьёзным падением производительности. Вместо SNA, которая должна использоваться по-умолчанию. p9/branch: $ grep 'model name' /proc/cpuinfo | sort -u model name : Intel(R) Core(TM) i3-5005U CPU @ 2.00GHz # cat /etc/X11/xorg.conf.d/10-monitor.conf # Generated by xsetup Section "Monitor" Identifier "Monitor0" EndSection Section "Device" Identifier "Card0" # Driver "modesetting" Driver "intel" Option "AccelMethod" "SNA" EndSection # glxinfo | sed -n '59,61p' OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2) x86/MMX/SSE2 OpenGL core profile version string: 4.5 (Core Profile) Mesa 19.0.4 # grep 'SNA\|UXA\|oad' /var/log/Xorg.0.log [ 28.466] (II) Loader magic: 0x82ac6c0 [ 28.482] (II) LoadModule: "glx" [ 28.488] (II) Loading /usr/lib/X11/modules/extensions/libglx.so [ 28.598] (II) LoadModule: "intel" [ 28.599] (II) Loading /usr/lib/X11/modules/drivers/intel_drv.so [ 28.635] (**) intel(0): Option "AccelMethod" "SNA" [ 28.648] (II) Loading sub module "fb" [ 28.648] (II) LoadModule: "fb" [ 28.651] (II) Loading /usr/lib/X11/modules/libfb.so [ 28.667] (II) Loading sub module "dri2" [ 28.667] (II) LoadModule: "dri2" [ 28.718] (II) UXA(0): Driver registered support for the following operations: [ 30.261] (II) AIGLX: Loaded and initialized i965 [ 30.583] (II) LoadModule: "evdev" [ 30.583] (II) Loading /usr/lib/X11/modules/input/evdev_drv.so [ 30.605] (II) LoadModule: "libinput" [ 30.606] (II) Loading /usr/lib/X11/modules/input/libinput_drv.so [ 30.840] (II) LoadModule: "synaptics" [ 30.841] (II) Loading /usr/lib/X11/modules/input/synaptics_drv.so Субмодуль dri3 не загружается. Вместо SNA используется UXA акселерация. $ man intel | col -bfx | sed -n '131,144p' Option "AccelMethod" "string" Select acceleration method. There are a couple of backends available for accelerating the DDX. "UXA" (Unified Acceleration Architecture) is the mature backend that was introduced to sup‐ port the GEM driver model. It is in the process of being super‐ seded by "SNA" (Sandybridge's New Acceleration). Until that process is complete, the ability to choose which backend to use remains for backwards compatibility. In addition, there are a pair of sub-options to limit the acceleration for debugging use. Specify "off" or "none" to disable all acceleration, or "blt" to disable render acceleration and only use the BLT engine. Default: use SNA (render acceleration)

Зачем сделали disabled sna for i586? https://packages.altlinux.org/ru/sisyphus/srpms/xorg-drv-intel Которая работает в текущей Слаке 32 бит (post 14.2) по-умолчанию, но сейчас не работает в альтах 32 бит на p9.
