英特尔Graphis卡未更新。 ppa有问题吗?

我正在尝试更新我的显卡。 信息:

description: VGA compatible controller product: 2nd Generation Core Processor Family Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 

我尝试过两种方式:

1。 命令行:

首先添加存储库:

  sudo add-apt-repository ppa:glasen/intel-driver 

二,更新:

 sudo apt-get update 

这会更新所有内容,然后最终我遇到问题:

 W: Failed to fetch http://ppa.launchpad.net/glasen/intel-driver/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found W: Failed to fetch http://ppa.launchpad.net/glasen/intel-driver/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. 

2。 适用于Linux的英特尔(R)图形安装程序:

我是从这个网站下载的

然后运行程序,让它做到这一点。 最终我收到了这个错误:

 W:GPG error: https://download.01.org trusty InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY A902DDA375E52366, W:Failed to fetch http://ppa.launchpad.net/glasen/intel-driver/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found , W:Failed to fetch http://ppa.launchpad.net/glasen/intel-driver/ubuntu/dists/trusty/main/binary-i386/Packages 404 Not Found , E:Some index files failed to download. They have been ignored, or old ones used instead. 

两个错误看起来都一样,但我不太明白。

如何升级显卡驱动程序?

首先摆脱ppa,因为它不需要,这就是导致你的问题的原因

 sudo rm /etc/apt/sources.list.d/glasen-intel-driver-saucy.list 

要安全地添加密钥,请执行这些命令

 GET https://download.01.org/gfx/RPM-GPG-KEY-ilg | gpg --import gpg --check-sigs --fingerprint 75E52366 gpg --keyserver pgpkeys.mit.edu --recv-key 7CB0FA13 gpg -a --export 75E52366 | sudo apt-key add - 

重复第二个键

 GET https://download.01.org/gfx/RPM-GPG-KEY-ilg-2 | gpg --import gpg --check-sigs --fingerprint 2F4AAA66 gpg --keyserver pgpkeys.mit.edu --recv-key 144BD458 gpg -a --export 2F4AAA66 | sudo apt-key add - 

有关添加密钥的更多信息, 请访问http://www.debian.org/doc/manuals/securing-debian-howto/ch7.en.html#s-deb-pack-sign


现在执行这些命令,为14.04 64位添加intel下载安装程序

 cd && wget https://download.01.org/gfx/ubuntu/14.04/main/pool/main/i/intel-linux-graphics-installer/intel-linux-graphics-installer_1.0.5-0intel1_amd64.deb sudo apt-get update sudo apt-get install gdebi sudo gdebi intel-linux-graphics-installer_1.0.5-0intel1_amd64.deb 

现在运行intel图形安装程序在打开的终端中运行以下命令

 intel-linux-graphics-installer 

按照intel安装程序GUI提供的说明进行操作。 保存您可能拥有的任何未保存的工作,然后重新启动以使更改生效。

要从01.org正确下载,您需要导入他们的GPG密钥,如发行版和安装说明中所述 。 您可能还想禁用glasen ppa,除非您打算继续尝试该源。

 wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg -O - | \ sudo apt-key add - wget --no-check-certificate https://download.01.org/gfx/RPM-GPG-KEY-ilg-2 -O - | \ sudo apt-key add -
