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
我尝试用两种方法做到这一点:
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
这将更新所有内容,但最终我遇到了一个问题:
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. Linux 版英特尔(R) 图形安装程序:
我从本网站
然后运行程序,让它执行操作。最后我得到了这个错误:
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.
两个错误看起来相同,但我不太明白。
如何升级我的显卡驱动程序?
答案1
首先删除 ppa,因为它是不需要的,这就是导致你出现问题的原因
sudo rm /etc/apt/sources.list.d/glasen-intel-driver-saucy.list
要安全地添加密钥,请执行以下命令
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 -
对第二个键重复上述操作
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 -
关于添加密钥的更多信息可以在这里找到http://www.debian.org/doc/manuals/securing-debian-howto/ch7.en.html#s-deb-pack-sign
现在执行这些命令来添加英特尔下载安装程序 14.04 64 位
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
现在运行英特尔图形安装程序,在打开的终端中运行以下命令
intel-linux-graphics-installer
按照英特尔安装程序 GUI 提供的说明进行操作。保存所有未保存的工作并重新启动以使更改生效。
答案2
要从 01.org 正确下载,您需要导入他们的 GPG 密钥,如发行和安装说明。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 -
