Dynabook SS 2010 + Ubuntu で全画面表示を高速化
前回の記事で、VESAドライバを使えば
Dynabook SS 2010で全画面表示ができるところまでは検証した。
1024×768で表示されるのはうれしいけれど、VESAドライバじゃ、やっぱ遅い。
もうちょっと何とかならんか？
lspci で調べてみると、ビデオチップは、
Trident CyberBlade XP Ai1
らしい。これ、Xorgのサポート対象に入っている模様。
ということで、早速、ドライバを “trident" としてみるが、
800×600の表示になってしまう。うーむ、、、
調べてみたら、FreeBSDな方の記事が見つかった。
dynabook C7/212CMENにFreeBSDをインストール
http://www10.plala.or.jp/dsuke3/bsdinstall.html
これによると、どうやら、水平・垂直の同期周波数
（HorizSync, VertRefresh）を指定するのがキモらしい。
ということで、xorg.confのビデオ周りを
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
HorizSync 28.0-50.0
VertRefresh 60.0-60.0
EndSection
Section "Device"
Driver "trident"
BusID "PCI:1:0:0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1024x768"
EndSubSection
EndSection
としてみたら、見事に、tridentのドライバで1024×768の表示ができた。
ありがたや。
体感的にはちょっと早いような気がするけれど、よくわからない。
ということで、ベンチマークテスト。
