雖然已經換M10，M8其實還是有它的用途，M8 原廠作業系統用起來卡的，很慢。
M8刷入 Android 7.1.1 牛軋糖快得像飛似的。

主要下兩個檔案

ROM
http://dwnld.aicp-rom.com/?device=m8

GAPPS-  ARM/7.1/stock
http://opengapps.org/

TWRP Recovery必備，且版本請到2.8.6.0以上


下面原廠寫得比我好，我簡單翻譯

下載ROM和GAPPS複製到手機SD卡，並將boot.img另外取出放到電腦手機SDK工具目錄。

fastboot flash boot boot.img

fastboot reboot

安裝ROM和GAPPS

  Step 12 – Now go back to the main menu and then tap on the ‘Install’ button. From the list, choose the ZIP file that you copied to your phone memory in Step 3.
  Step 14 – Once the installation is completed, you will be shown a similar screen like the following:
  Google Apps: Repeat the above step for the Gapps zip file as well and install it on your phone.

一杯咖啡的時間，一輩子的回憶

今年8月29日，也是全國小一新生入學的日子，應邀於我的母校天母國小，以過來人的身分，與新生家長分享如何陪伴小一新鮮人，快樂學習健康成長，並以親子陪伴孩子閱讀與運動為主軸，除揭示運動對孩子的重要性外，也分享他陪伴孩子每日睡前讀床邊故事的經驗，也藉此機會拋磚引玉，期待父母能每日花一點點時間，如喝一杯咖啡的時間，為孩子讀床邊故事，日積月累長此以往，卻是孩子一輩子的甜蜜的回憶。

如何陪伴小一新鮮人，快樂學習健康成長

$ packstack
如果失敗,解決問題後用以下指令繼續安裝
$ packstack --answer-file=/root/packstack-answers-xxxxxxxxxx.txt

Q&A

<<< DB >>>
Q1:
Icehouse  puppet DB pid error
A1:
$ vi /usr/lib/python2.7/site-packages/packstack/puppet/templates/mongodb.pp
pidfilepath => '/var/run/mongodb/mongod.pid'

Q2:
Error: Execution of '/usr/bin/yum -d 0 -e 0 -y install mongodb-server' returned 1: Yum command has been deprecated, redirecting to '/usr/bin/dnf -d 0 -e 0 -y install mongodb-server'.

ps: operatingsystemrelease, '23'  or 22 or 21 or other

Q3:
 packstack get python-eventle error
A3:
删除最新版本， pip uninstall eventlet

再重新安装0.15版本解决，用yum自带的吧yum reinstall python-eventle

Q4:
ERROR : Error appeared during Puppet run: x.x.x.x_keystone.pp
Error: /Stage[main]/Neutron::Keystone::Auth/Keystone_user[neutron]:

$ mysql

Q5:
ERROR : Error appeared during Puppet run: x.x.x.x_provision_demo.pp
Error: Failed to apply catalog: Can't retrieve net-show because Neutron or Keystone API is not available.

Unable to find network with name 'from gi.repository import GnomeKeyring'". Retrying for 5 sec.
Notice: Puppet::Type::Neutron_network::ProviderNeutron: Unable to complete neutron request due to non-fatal error: "Execution of '/usr/bin/neutron net-show --format=shell from gi.repository import GnomeKeyring' returned 1: /usr/lib/python2.7/site-packages/keyring/backends/Gnome.py:6: PyGIWarning: GnomeKeyring was imported without specifying a version first.

Error: Failed to apply catalog: Can't retrieve net-show because Neutron or Keystone API is not available.

A5:
** You can "fix" (?) this problem by modifying the top of /usr/lib/python2.7/site-packages/keyring/backends/Gnome.py, replacing this:

    try:
        from gi import Repository
        if Repository.get_default().enumerate_versions('GnomeKeyring'):
            from gi.repository import GnomeKeyring
    except ImportError:
        pass

With this:

    try:
        from gi import Repository, require_version
        if Repository.get_default().enumerate_versions('GnomeKeyring'):
            require_version('GnomeKeyring', '1.0')
            from gi.repository import GnomeKeyring
    except ImportError:
        pass

NOVA Client install
------------------------

$ yum install openstack-nova-compute sysfsutils

$ egrep -c '(vmx|svm)' /proc/cpuinfo

If this command returns a value of one or greater, your compute node supports hardware acceleration which typically requires no additional configuration.
If this command returns a value of zero, your compute node does not support hardware acceleration and you must configure libvirt to use QEMU instead of KVM.

    Edit the [libvirt] section in the /etc/nova/nova.conf file as follows:
    [libvirt]
    virt_type = qemu

$ service openstack-nova-compute start
$ service messagebus start
$ service libvirtd start

$ chkconfig openstack-nova-compute on
$ chkconfig libvirtd on
or
$ systemctl enable libvirtd.service openstack-nova-compute.service
$ systemctl start libvirtd.service openstack-nova-compute.service

nova image-list

這個問題,我已經更新到到最新的驅動程式及patch
試過了以下所有方法（請不要試）
1.改seting檔 2 or 1 to 0 強迫用 DirectX 10
2.刪除兩個遊戲目錄下的檔案....開遊戲更新後不就又恢復了嗎? 很呆, 但我是還試了.
3.把草的顯示品質調低
4.把垂直同步....等一堆功能調低或關閉......等等

以上都不是正確的解法

真正的原因....顯示卡出廠時就已經超頻了

1.下載 nvidiaInspector
2.程式開啟後點選Diver Version旁的圖案, 查看顯示卡官方出廠的GPU clock是多少,目前超頻了多少.
3.點選Show overclock,再右邊選項調低GPU clock至公版出廠值.
4.點選apply clocks&change你會發現左邊GPU會降低.
5.點選create clock shortcute,如果重開機設定會恢復, 在桌面點此捷徑可恢復降頻設定.

經過調整後GTA 5 再也沒有當機出現ERR_GFX_D3D的錯誤當機狀況
