红帽屏幕180旋转

 

终端显示旋转180度 

 

 

 

 

 

sed -i "s/rhgb/fbcon=rotate:2/g" /etc/default/grub

 

grub2-mkconfig -o /boot/grub2/grub.cfg

reboot

 

 

图形化界面显示旋转180度 

要用到“fbdev”驱动，系统默认是已经安装

将/etc/X11/xorg.conf的“Driver”的驱动内容替换为“fbdev”

增加Option “Rotate” “UD”进行180翻转

 

cat >> /etc/X11/xorg.conf <<EOF

 

Section "InputClass"

        Identifier "libinput feitian catchall"

        Driver "libinput"

        Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"

EndSection

 

Section "Device"

Identifier  "Card feitian"

Option    "Rotate""UD"

Driver      "fbdev"

EndSection

 

EOF
