Geo*_*ata 10 nvidia vlc vdpau drivers 20.04
VLC 无法在 Ubuntu 20.04.3 LTS 上运行。
它随机冻结图像，但音频继续播放。
或者它随机崩溃。
或者它会随机冻结整个电脑。
我首先尝试了 VLC 的 snap 版本。
然后我切换到了sudo apt install vlc以便从终端启动它并记录一些错误：
$ vlc 4.mp4

我有 GTX 1080 和 Intel i7 7700k。
在Additional Drivers我选择了：Using NVIDIA driver metapackage from nvidia-driver-470(proprietary,tested)。

无论出于何种原因，Ubuntu 都看不到 Intel 驱动程序，即使我安装了它们：
$ sudo apt-get install xserver-xorg-video-intel

xserver-xorg-video-intel is already the newest version (2:2.99.917+git20200226-1).
The following packages were automatically installed and are no longer required:
gyp javascript-common libc-ares2 libjs-inherits libjs-is-typedarray libjs-psl libjs-typedarray-to-buffer libnode-dev libnode64

python2-minimal python2.7 python2.7-minimal
Use 'sudo apt autoremove' to remove them.

我也删除了~/.config/vlc/很多次以重置VLC但无济于事。
我认为 VLC 在 Ubuntu 20 上就被破坏了。
这降低了生产力，因为我没有花几个小时观看教程，而是花了几个小时来找出 VLC 出了什么问题，但一无所获。
我需要一个能够显示字幕、改变播放速度、能够来回跳跃、保存视频播放列表并且在播放 2 分钟后不会崩溃的媒体播放器。
我尝试过图腾，但它缺乏这些功能。
这台机器的历史是什么？这里第一次安装的是哪个版本的Ubuntu？
我已格式化所有可用驱动器，在一个驱动器上安装 Ubuntu 20.04.3 LTS，在另一个驱动器上安装 Windows 10 Pro x64。
这是我第一次安装和使用Ubuntu。

使用相当旧的 Nvidia GT425M 和 Ubuntu MATE 22.04 LTS（开发版本）进行确认。需要注意的是，我在真实硬件上没有 Ubuntu 20.04 LTS，因此测试了最新版本。
您刚刚发现了众所周知的错误 1890815。请将自己标记为受影响。
可以通过使用以下命令手动下载并安装包含nvidia_drv_video.so的相关软件包来修复：
cd ~/Downloads
wget -c http://archive.ubuntu.com/ubuntu/pool/universe/v/vdpau-video/vdpau-va-driver_0.7.4-6ubuntu1_amd64.deb
sudo apt-get install ./vdpau-va-driver_0.7.4-6ubuntu1_amd64.deb
并重新启动。
