![使用带有视频加速 (VA) 的 nvidia 驱动程序时出现“失败请求的 X 错误:BadRequest”](https://linux22.com/image/1057487/%E4%BD%BF%E7%94%A8%E5%B8%A6%E6%9C%89%E8%A7%86%E9%A2%91%E5%8A%A0%E9%80%9F%20(VA)%20%E7%9A%84%20nvidia%20%E9%A9%B1%E5%8A%A8%E7%A8%8B%E5%BA%8F%E6%97%B6%E5%87%BA%E7%8E%B0%E2%80%9C%E5%A4%B1%E8%B4%A5%E8%AF%B7%E6%B1%82%E7%9A%84%20X%20%E9%94%99%E8%AF%AF%EF%BC%9ABadRequest%E2%80%9D.png)
我想简单地展示一个使用 gstreamer-1.0 的测试源。当我使用(我猜)非加速输出时,gst-launch-1.0 videotestsrc ! xvimagesink
一切都正常,但当我尝试播放它时,gst-launch-1.0 videotestsrc ! autovideosink
我收到以下错误:
Setting pipeline to PAUSED ...
libva info: VA-API version 0.35.0
X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 153 (DRI2)
Minor opcode of failed request: 1 (DRI2Connect)
Serial number of failed request: 15

我已安装NVIDIA-Linux-x86_64-367.44.run
如下Ubuntu 14.04.5
:
- 删除旧驱动程序:
sudo apt-get remove --purge nvidia*
- 通过运行脚本将旧驱动程序列入黑名单(它会要求你这样做,然后退出)
- 重启
- 停止服务:
service lightdm stop && service x11-common stop
- 安装驱动程序:
./NVIDIA-Linux-x86_64-367.44.run --no-x-check
- 已安装 VA 相关内容https://wiki.ubuntuusers.de/Video-Dekodierung_beschleunigen/:
sudo apt-get install libvdpau1 vdpauinfo vdpau-va-driver vainfo
- 重启
以下是一些有用的输出,但仍会产生错误:

有人能提供提示吗?我知道按照说明操作后这台电脑曾经能用,但现在好像出了点问题。

通过将所有内容恢复为原始 Ubuntu 来修复它,但视频加速仍然不起作用:
- 删除前任司机:
sudo ./NVIDIA-Linux-x86_64-xxx.xx.run --uninstall
- 卸载与 nvidia 相关(通过 搜索相关软件包
dpkg -l
):nvidia、cuda、primus、vdpau-va-driver、vainfo、libvdpau1、vdpauinfo - 删除 nouveau 驱动程序的所有黑名单内容:删除
/etc/modprobe.d
- 通过以下方式恢复 xconfig:
sudo X -configure && sudo cp xorg.conf.new /etc/X11/xorg.conf
- 重新安装
mesa-vdpau-drivers-lts-<your release>
- 重要的:删除 gstreamer vaapi,以便它在使用类似
autoconvert
或autovideosink
的插件时不会尝试使用加速:sudo apt-get remove gstreamer1.0-vaapi gstreamer1.0-vaapi-doc libgstreamer-vaapi1.0-0:amd64 libgstreamer-vaapi1.0-dev
现在,测试程序glxinfo
再次glxgears
按预期运行。
无论如何:失败的尝试:我仍然不知道为什么即使使用官方 ppa,VA 东西也无法与原始驱动程序一起工作:
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install --install-suggests nvidia-340
glxinfo
并glxgears
正常工作,但vainfo
仍然vdpauinfo
输出错误。我设法vdpauinfo
通过使用驱动程序和导出来输出错误以外的内容mesa
(如果变量指向专有驱动程序,它将不起作用):
export VDPAU_DRIVER_PATH=/usr/lib/x86_64-linux-gnu/vdpau/
export VDPAU_DRIVER=va_gl
但这只是显示驱动程序,对吧。所以我需要告诉 VA API,它必须vdpau
像这样使用(?):
export LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri/
export LIBVA_DRIVER_NAME=vdpau
但在那种情况下,vainfo
无论我选择哪个驱动程序名称,都只会回复错误。
如果有人知道如何使其工作,请帮忙。 但目前,gstreamer 可以再次运行(但 CPU 负载较高)。
