如何使用ubuntu驱动程序更改图形卡驱动程序？

Question

我想核实什么驱动程序是目前使用的NVIDIA，然后切换驱动程序到nvidia-331-更新，如有必要。

我该如何做到这一点？

sudo ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00000FFBsv00001462sd000010DBbc03sc00i00
model    : GK107GLM [Quadro K2000M]
vendor   : NVIDIA Corporation
driver   : nvidia-331-updates - distro non-free
driver   : nvidia-304 - distro non-free
driver   : nvidia-304-updates - distro non-free
driver   : xserver-xorg-video-nouveau - distro free builtin

sudo ubuntu-drivers list
nvidia-304
nvidia-331
nvidia-331-updates
nvidia-304-updates

(我尝试了sudo ubuntu-drivers autoinstall和sudo ubuntu-drivers autoinstall nvidia-331-updates -绝望地，因为缺少有用的帮助文本-但没有结果)

最近也提出了一个类似的问题(如何使用命令行中的ubuntu驱动程序(公共或软件)属性来更改图形驱动程序？)，但提问者接受了一个没有真正回答问题的答案。所以我想再试一次。

首先，我之所以对此感兴趣，是因为在试图设置第二个监视器之后，图形化的“附加驱动程序”-tool突然停止工作。

不，你不能。至少用那个工具不行。没有一个命令可以帮助您安装不同的驱动程序：

list: Show all driver packages which apply to the current system.
debug: Print all available information and debug data about drivers.
devices: Show all devices which need drivers, and which packages apply to them.
autoinstall: Install drivers that are appropriate for automatic installation.

list不安装，而是列出。debug只是打印更多的信息。devices信息丰富。autoinstall不允许其他参数：

def command_autoinstall(args):
    '''Install drivers that are appropriate for automatic installation.'''

    cache = apt.Cache()

    packages = UbuntuDrivers.detect.system_driver_packages(cache)
    packages = UbuntuDrivers.detect.auto_install_filter(packages)
    if not packages:
        print('No drivers found for automatic installation.')
        return

    # ignore packages which are already installed
    to_install = []
    for p in packages:
        if not cache[p].installed:
            to_install.append(p)

    if not packages:
        print('All drivers for automatic installation are already installed.')
        return

    ret = subprocess.call(['apt-get', 'install', '-o',
        'DPkg::options::=--force-confnew', '-y'] + to_install)

    # create package list
    if ret == 0 and args.package_list:
        with open(args.package_list, 'a') as f:
            f.write('\n'.join(to_install))
            f.write('\n')

    return ret

您可以忽略该工具，并使用apt手动安装包，然后按照您获得的输出。只需移除一个软件包并安装另一个：

sudo apt-get install nvidia-331-updates
