画面の左右の上100ピクセルを削除するために変換を使用してみました1366x768
(下記参照)xrandr
。しかし、フレームバッファサイズが不足しているというエラーが発生します。
$ xrandr --output LVDS1 --fb 1366x768 --transform 1.171527,0.152543,-117.152659,0.000000,1.171527,0.000000,0.000000,0.000223,1.000000
xrandr: specified screen 1366x768 not large enough for output LVDS1 ( 1602x773+-118+0)
だからメッセージに言及されたサイズでサイズアップしました1602x773
!それは動作します:
xrandr --output LVDS1 --fb 1602x773 --transform 1.171527,0.152543,-117.152659,0.000000,1.171527,0.000000,0.000000,0.000223,1.000000
この追加領域は何1366x5+236x768+236x5
で、なぜ必要なのですか? !
変換対象領域が元の領域(元の画面サイズ)より小さいです!まあ、私はそれらが同じ長方形の面積を持っていると言うことができます。
ハードウェア、ドライバ、またはxorg関連の可能性があるため、ここに現在の設定を追加しました。
