一般Ubuntu都默认包含了Intel显卡的驱动，如果没有，那么先确定是不是显卡太高，比如I7第7代的CPU核显在Ubuntu 16.04中是没有的，导致画面会很卡，原因是Linux 4.4内核不包含Intel HD Graphics 630驱动，解决方法只能是在Ubuntu 16.04中升级Linux内核为4.7的。
以下是两种解决方法：
一、一般Intel显卡驱动安装及升级
下载intel-graphics-update-tool进行安装，中途会出现依赖问题：
wget https://download.01.org/gfx/ubuntu/16.04/main/pool/main/i/intel-graphics-update-tool/intel-graphics-update-tool_2.0.2_amd64.deb
sudo dpkg -i intel-graphics-update-tool_2.0.2_amd64.deb
sudo intel-graphics-update-tool
sudo apt-get install -f
sudo intel-graphics-update-tool
wget $(echo"https://download".01.org/gfx/RPM-GPG-GROUP-KEY-ilg) -O - (专业提供视频软件下载)
sudo apt-key add -
sudo apt-get update
然后运行sudo intel-graphics-update-tool会出现如下错误提示：
W:GPG error: https://download.01.org/gfx/ubuntu/16.04/main xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 56A3DEF863961D39, W:The repository 'https://download.01.org/gfx/ubuntu/16.04/main xenial InRelease' is not signed., W:Data from such a repository can't be authenticated and is therefore potentially dangerous to use., W:See apt-secure(8) manpage for repository creation and user configuration details., W:There is no public key available for the following key IDs:

解决方法是添加两个签名：
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg -O - (专业提供视频软件下载)
sudo apt-key add -
wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-4 -O - (专业提供视频软件下载)
sudo apt-key add -
然后运行sudo intel-graphics-update-tool会出现如下错误提示：
W:https://download.01.org/gfx/ubuntu/16.04/main/dists/xenial/InRelease: Signature by key 09D6EF97BFB38E916EF060E756A3DEF863961D39 uses weak digest algorithm (SHA1), E:Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi', E:Sub-process returned an error code
解决方法：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 09D6EF97BFB38E916EF060E756A3DEF863961D39
sudo apt-get update
sudo pkill -KILL appstreamcli
wget -P /tmp https://launchpad.net/ubuntu/+archive/primary/+files/appstream_0.9.4-1ubuntu1_amd64.deb https://launchpad.net/ubuntu/+archive/primary/+files/libappstream3_0.9.4-1ubuntu1_amd64.deb
sudo dpkg -i /tmp/appstream_0.9.4-1ubuntu1_amd64.deb /tmp/libappstream3_0.9.4-1ubuntu1_amd64.deb
sudo apt-get update
然后运行sudo intel-graphics-update-tool会出现如下错误提示：
Error running transaction: GDBus.Error:org.debian.apt.TransactionFailed: error-dep-resolution-failed: The following packages have unmet dependencies:
libgles1-mesa: Depends: libglapi-mesa (= 12.0.6-0ubuntu0.16.04.1) but 17.0.7-0ubuntu0.16.04.1 is to be installed
The following packages have unmet dependencies:
libgles1-mesa: Depends: libglapi-mesa (= 12.0.6-0ubuntu0.16.04.1) but 17.0.7-0ubuntu0.16.04.1 is to be installed
解决方法：
sudo add-apt-repository ppa:paulo-miguel-dias/pkppa && sudo apt-get update
然后运行sudo intel-graphics-update-tool后基本正常安装了。
但是以上方式即使全部安装之后都不能解决Intel HD Graphics 630显卡的驱动。
二、解决Intel HD Graphics 630显卡驱动问题
升级Linux 4.7的内核，如下（Ubuntu 16.04升级Linux内核为4.7.0最快的方法）：
