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
我尝试通过两种方式执行此操作:
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。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
然后运行该程序,让它完成任务。最终我得到了这个错误:
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.
两种错误看起来都一样,但我不太了解。
如何升级显卡驱动程序?
首先摆脱ppa,因为它是不需要的,这就是导致您出现问题的原因
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 -
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,请参见http://www.debian.org/doc/manuals/securing-debian-howto/ch7.en.html#s-deb-pack-sign
现在执行以下命令以添加适用于14.04 64位的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
现在要运行intel图形安装程序,请在打开的终端中运行以下命令
intel-linux-graphics-installer
请按照intel安装程序GUI提供的说明进行操作。保存您可能拥有的所有未保存的工作,然后重新启动以使更改生效。
