  • 红帽触摸屏屏幕180旋转

    红帽开机取消5秒等待 

    sed -i "s/GRUB_TIMEOUT=.*$/GRUB_TIMEOUT=0/g" /etc/default/grub

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

     reboot

     

    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

    /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
     

    触摸旋转鼠标旋转:
    步骤1.yum install xorg-x11-drv-libinput.x86_64
    步骤2. cp /usr/share/X11/xorg.conf.d/40-libinput.conf /etc/X11/xorg.conf.d/

    步骤3. 编辑/etc/X11/xorg.conf.d/40-libinput.conf
    找到 touchscreen 的部分。在里面添加以下语句,然后保存即可
    Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
    步骤4. 最后reboot
