Dynabook SS 2010 + Ubuntu で全画面表示をもっと高速化
Tridentのドライバを使うようにして、
ある程度は早くなったSS2010のUbuntu君。
それでもまだまだ鈍い感じは否めない。
もっと早くしてやろうと思えば、
解像度を下げるのも手だろうけど、さすがにそれはやりたくない。
他にできそうなことといえば、色数を減らすことか?
ということで、24ビットカラーを諦めて16ビットカラーにしてみる。
xorg.confはこんな感じ（ビデオ周りだけ抜粋）。
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 28.0-50.0
VertRefresh 60.0-60.0
EndSection
Section "Device"
Identifier "Card0"
Driver "trident"
BusID "PCI:1:0:0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 16
SubSection "Display"
Viewport 0 0

EndSubSection
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection
EndSection
「DefaultDepth 16」を指定しているのがミソ。
ということで、ベンチマークテスト。
まずは、24ビットカラーの結果。

だいぶ向上したようだ。
早速、YouTubeを見てみたが、残念ながら動画再生は厳しいようである。
まぁ、それでも24ビットカラーよりは多少はマシだけど。
とりあえず、描画の高速化についてはこれで一旦終了。
もっといい方法があったら教えてください。
