如何在Ubuntu 18.04,18.10中通過PPA安裝Mesa 18.2.8

最新的Mesa圖形驅動程式18.2.8最終可以通過Ubuntu-X PPA安裝在Ubuntu 18.04和Ubuntu 18.10中。

Mesa 18.2.8兩週前發布了，有以下變化：

• 新增新的Vega M，Vega 10和Vega 20 PCI ID
• Meson構建系統foxes。
• Gallium“Nine”Direct3D 9狀態跟蹤器修復。
• VirGL驅動程式修復。
• 使用Steam Play在DXVK下進行Windows Yakuza遊戲的RADV掛起修復

對於堅持使用開源RadeonSI/RADV/Intel/Nouveau驅動程式並希望享受一些Linux遊戲的使用者，您可以按照以下步驟在Ubuntu 18.04和/或Ubuntu 18.10中安裝Mesa 18.2.8：

1.通過Ctrl + Alt + T鍵盤快捷鍵或從軟體啟動器開啟終端。 開啟時，執行命令：

linuxidc@linuxidc:~/www.linuxidc.com$ sudo add-apt-repository ppa:ubuntu-x-swat/updates
[sudo] linuxidc 的密碼：
 Updated versions of X.org drivers, libraries, etc. for Ubuntu.

This PPA is for stable upstream releases of X.org components. If you're looking for something even more bleeding-edge, please see the xorg-edgers PPA.

While Ubuntu does not "officially/formally" support these packages, if you discover problems when installing these debs please feel free to report bugs to launchpad. However, please make sure to clearly state that you are running packages from this PPA so we know the fixes need to come here.

If you are upgrading from one release to another with this PPA activated, please install the ppa-purge package and use it to downgrade everything in here beforehand. sudo ppa-purge ppa:ubuntu-x-swat/updates will do it.

[Directions for packaging drivers can be seen at https://wiki.ubuntu.com/X/DriverBuilding]

2.新增PPA後，通過命令進行系統更新：
