我有 Ubuntu 14.04 x64 和明基EW2440L作為第二個顯示器。
我遇到的問題是第二個螢幕確實很滯後,幾乎無法使用。
我嘗試過 Compiz,並手動設定它,如下xrandr
所示:
xrandr -s 1920x1080 -r 50
但我明白了Size 1920x1080 not found in available modes
。
這是運行時的輸出xrandr

我的顯示卡肯定是打開的,因為運行glxinfo | grep rendering
會產生direct rendering: Yes
。
我在網路上找到的沒有任何幫助,所以我要么非常接近,但做錯了什麼,要么我遇到了完全不同的問題。
