Ubuntu 安装vlc之后无法正常打开命令行输入`vlc`,显示如下错误信息:
```sh
> vlc
/usr/share/libdrm/amdgpu.ids: No such file or directory
amdgpu: unknown (family_id, chip_external_rev): (146, 32)
libGL error: failed to create dri screen
libGL error: failed to load driver: radeonsi
VLC media player 3.0.20 Vetinari (revision 3.0.20-1-g2617de71b6)
[00006310db453a10] main libvlc: 正在以默认界面运行 vlc。使用“cvlc”可以无界面模式使用 vlc。
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Qt: Session management error: Could not open network socket
Fontconfig warning: FcPattern object width does not accept value [75 100)
[1] 238348 segmentation fault (core dumped) vlc
```
<!--more-->
解决方案如下:
```sh
sudo rm /var/cache/fontconfig/*
rm ~/.cache/fontconfig/*
fc-cache -r
```
上述命令执行完之后再次打开vlc需要等待一段时间然后就可以正常使用。
第二种解决方案是使用 `sudo apt install vlc` 安装不要用snap。先卸载snap的vlc再安装就可以正常打开了。
具体是什么原因不是很清楚,本地网络不通也会出现这个错误。
