[debian-users:39896] savagefb
坂本と申します。
silinuxをAdvantech社のPCM9372にいれているのですが、fb consoleとして
savagefbを使って見たいのですがまともにモニタに映すことが出来ないでいます。
(ちなみにvesafbでは何の問題もありません)
si-linux-chroot_2.00pre1を使用して
カーネルはkernel.orgの2.4.19に、DirectFB(http://directfb.org/)の
patchの下のsavagefb-0.4.0-linux-2.4.19.patch.bz2をパッチあてています。
ちゃんと認識しているようですし、エラーも出ていないのですが、解像度が変わっ
た時点でモニタに信号は出力されているようですがモニタの範囲を超える周波数
になってしまっている感じです。
これを解決できる方法があるのか、liloでsavagefbに与えるパラメータもどうい
うものがあるのかというような情報はないでしょうか。
海外のサイトとかも検索して見たのですが情報が少なく有用な情報が得られませ
んでした。
