是否 因爲 硬體 的差別
等一下 再查

Google Earth 完全正常

Google Earth 有 2D 及 3D 顯示
如果只是需要 2D 的需求 這個部分 會正常
差別只有在 3D 的需求 部分

另外 如果你所說的 完全正常
如果是在 mate 桌面環境
那對 3D 的支援 應該是不足的

MATE (Spanish pronunciation: [ˈmate]) is a desktop environment forked from the now-unmaintained code base of GNOME 2.

如果我沒記錯的話
GNOME 2 一樣可以玩 Compiz 玩的很兇，自己還包含特效的設定頁面

內建 Intel® G31

0. 晶片與顯卡
0-1. 晶片 : G31/G33
0-1-1. 內建 顯卡 GMA 3100 graphics
0-2. 晶片 : GL960/GM965
0-2-1. 內建 顯卡 GMA X3100 graphics

1. 顯卡演進及比較

1-1. GMA 3000 : 獨立顯卡

The 946GZ, Q965, and Q963 chipsets use the GMA 3000 chip.[5][6] The GMA 3000 3D core is very different from the X3000, despite their similar names. It is based more directly on the previous generation GMA 900 and GMA 950 graphics, and belonging to the same "i915" family with them. It has pixel and vertex shaders which only support Shader Model 2.0b features[citation needed], and the vertex shaders are still only software-emulated. In addition, hardware video acceleration such as hardware-based iDCT computation, ProcAmp (video stream independent color correction), and VC-1 decoding are not implemented in hardware. Of the GMA 3000-equipped chipsets, only the Q965 retains dual independent display support. The core speed is rated at 400 MHz with 1.6 Gpixel/s fill rate in datasheets, but was listed as 667 MHz core in the white paper.[7]

The memory controller can now address a maximum of 256 MB of system memory, and the integrated serial DVO ports have increased top speed to 270Mpixel/s.

1-2. GMA X3000 : 獨立顯卡 (是 GMA 3000 獨立顯卡 的 重新設計)

The GMA X3000 for desktop was "substantially redesigned" when compared to previous GMA iterations[8] and it is used in the Intel G965 north bridge controller.[9] The GMA X3000 was launched in July 2006.[10] X3000's underlying 3D rendering hardware is organized as a unified shader processor consisting of 8 scalar execution units. Each pipeline can process video, vertex, or texture operations. A central scheduler dynamically dispatches threads to pipeline resources, to maximize rendering throughput (and decrease the impact of individual pipeline stalls.) However, due to the scalar nature of the execution units, they can only process data on a single pixel component at a time.[11] The GMA X3000 supports DirectX 9.0 with vertex and pixel Shader Model 3.0 features.

The processor consists of different clock domains, meaning that the entire chip does not operate the same clock speed. This causes some difficulty when measuring peak throughput of its various functions. Further adding to the confusion, it is listed as 667 MHz in Intel G965 white paper, but listed as 400 MHz in Intel G965 datasheet. There are various rules that define the IGP's processing capabilities.[11]

Memory controller can now address maximum 384 MB memory according to white paper, but only 256 MB in datasheet.

1-2-1. GMA X3100 : GMA X3000 的 內建顯卡版本

The GMA X3100 is the mobile version of the GMA X3000 used in the Intel GL960/GM965 chipsets and also in the GS965 chipset. The X3100 supports hardware transform and lighting, up to 128 programmable shader units, and up to 384 MB memory. Its display cores can run up to 333 MHz on GM965 and 320 MHz on GL960. Its render cores can run up to 500 MHz on GM965 and 400 MHz on GL960. The X3100 display unit includes a 300 MHz RAMDAC, two 25–112 MHz LVDS transmitters, 2 DVO encoders, and a TV encoder. In addition, the hardware supports DirectX 10.0,[3] Shader Model 3.0 and OpenGL 1.5.[12]

3. 從 上面 看來
顯卡 GMA X3100 應該比 GMA 3000 性能 好一點

4. 關鍵就是 有沒有合適的 顯卡驅動 及 桌面環境 讓他發揮

5. G31/G33 並不支援虛擬技術
Intel® Virtualization Technology
G31/G33 : No
5-1. 946GZ/946PL 也應該不支援虛擬技術
5-2. 這個意思 是 任何 藉助 虛擬技術 的 程式 對這些 顯卡 可能 都沒有幫助
5-3. VirtualGL 是 Compiz 的 3D 技術之一 是否受到影響 值得關注與體驗
5-4. 這個 Bug report
Bug #861061
[regression] All apps have a lower frame rate under Unity.
有一百多篇貼文 看看是不是 有這個影子 :
summary: - compiz 3d performance regression + Running compiz makes 3D apps like glxspheres (VirtualGL) perform worse.
總結: 執行 compiz 3d 效率衰退 使得 glxspheres (VirtualGL) 立體球形 執行更差
5-5. 這個 Bug report
Bug #988079
Much slower OpenGL frame rates with unityshell loaded, than plain compiz
是上面那一篇 Bug Report 的後續 追蹤
5-6. 既然 VirtualGL 對於 Compiz 會產生影響
那完全不支援 VirtualGL 的顯卡 會 如何執行 Compiz ?

這個笑話我就轉貼了XDDDDD

我記得我之前說過了....我知道你們有些過節，但是我在這邊還是要說，希望你針對別人發言有不同意見的話能夠不要使用這種方式來進行，盡量保持著對別人的尊重。

希望不要再讓我多說第三次，麻煩了....
