我打算重新安装Ubuntu,并想知道安装ATI Catalyst Video Driver的正确方法是什么?
这个问题有多个有效答案,涵盖了多个版本的Ubuntu。为了您的方便,以下各索引:
首先,确保您的Ubuntu OS是最新的。要对此进行检查,请单击右上角的电源图标。从菜单中选择“关于此计算机”。现在,检查是否有一个“安装更新”按钮(可能在“检查更新”按钮之后几秒钟后出现),该按钮可用于更新,如下所示。如果不是,则您的系统是最新的。
(首先您可能会看到此信息)
(然后这个)
(按“安装更新”后,您将看到此信息)
还可以使用如下所示的terminal命令进行更新:
sudo apt-get update && sudo apt-get upgrade
然后转到AMD网站,手动选择驱动程序,然后下载。如果不确定要安装哪个驱动程序,则可以在Windows操作系统中安装“驱动程序检测软件”,然后查看应安装的驱动程序。
Check the release notes and installer notes of whichever driver you are going to install without fail. See if your OS meets all the system requirements mentioned in the release notes.
Then follow the steps in the installer notes to install your driver.
1: If you installed the wrong driver(or made some other mistake with installing the driver), Unity might crash or you may get "The system is running in low graphics mode" problem (or some other issue). Whatever the problem is, you have to first delete the driver you installed. For this, start a tty session by pressing CTRL+ALT+F1. Then use this command :
sudo aticonfig --uninstall
This should delete your driver. If not refer this . Now use the command:
sudo shutdown -r now
to reboot your system. This should help you to get back to unity without problems. Now you can again get to the AMD site, get a supported driver and install.
If this didn't solve your problem referring to these questions might be useful:
2: Also if you don't know if your OS satisfies the system requirements of the driver mentioned in its release notes, then the following commands might help:
uname -a
: will let you know about your KernelXorg -version
: will let you know about your Xorgldd --version
: will let you know your glibcAlso it is not necessary that your OS needs to specified in the release notes. Just see if you meet the system requirements and if your graphic card is mentioned in the release notes.
3: Make sure you update your OS before installing your graphics driver as stated above. While your OS might support your driver before updating, after your OS update it might not.
4: Also don't be startled if your driver installer appears like this (without any text):
In this case see the installer notes and with the help of the screen shots provided there install your driver.
P.S.:
以我的拙见,默认的开放源代码驱动程序可以满足所有正常的计算需求。因此,仅在确实需要时才安装专有驱动程序(例如,您是“高手”游戏玩家或诸如此类)。另外,如果您试图安装专有驱动程序只是为了获得最大屏幕分辨率,则可以参考此答案。
