安裝ubuntu 10.04的難題-解析度

00.一開使使解析度是1024*768
01.先到系統->偏好設定->螢幕->隨便調800*600->套用->回覆先前的組態->砍了這個檔 ~/.config/monitors.xml

02.開啟終端機，輸入$ gtf 1920 1200 60 -x

出現
# 1920x1200 @ 60.00 Hz (GTF) hsync: 55.92 kHz; pclk: 106.47 MHz
Modeline "1440x900_60.00"  193.16  1920 2048 2256 2592  1200 1201 1204 1242  -HSync +Vsync

再輸入sudo gedit /etc/X11/xorg.conf
