我使用具有預設驅動程式的 ElementaryOS，並且我的 Gala 進程不斷使用大量 CPU（有時超過 200%）。
我到處找過但找不到解決方案。我嘗試安裝專有的 ATI 驅動程序，但無法登入系統（黑屏）。
我的顯示卡是 ATI Mobility Radeon 5730。

我想我終於修好了！
我需要創建一個 xorg.conf 檔案並將正確的驅動程式添加到 radeon；之前是fbdev。
Section "Device"
### Available Driver options are:-
### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
### <percent>: "<f>%"
### [arg]: arg optional
#Option "ShadowFB" # [<bool>]
#Option "Rotate" # <str>
#Option "fbdev" # <str>
#Option "debug" # [<bool>]
Identifier "Card0"
Driver "radeon"
BusID "PCI:1:0:0"
EndSection
現在我的 glxinfo 不再顯示 libvmpipe：
OpenGL renderer string: Gallium 0.4 on AMD REDWOOD
GL_MESA_texture_signed_rgba, GL_NV_conditional_render, GL_NV_depth_clamp,
GL_MESA_window_pos, GL_NV_blend_square, GL_NV_conditional_render,
Gala 現在的 CPU 使用率為 0%。 @mikeserv，你的評論為我指明了正確的方向。我知道我的 X 是以某種方式被軟體渲染的，但不知道具體是如何渲染的。謝謝。
