Linux Luban cat screen and touch [Switch the screen to MIPI-1080P when using Luban cat for the first time] [Rotate the screen to horizontal screen display] [Permanently modify the screen and touch direction]

First use Luban cat to switch the screen to MIPI-1080P

Luban cat information:
boards are purchased from the following address: https://detail.tmall.com/item.htm?_u=110jcean66aa&id=694560455663&spm=a1z09.2.0.0.56f52e8dj4eUdI&skuId=5156903694777

tutorial: https://space.bilibili.com/356820657/channel/collectiondetail?sid=1352573
The physical picture of the board is as follows:

Burn the Luban cat image
According to the video tutorial, here use EMMC to burn the image, select the following image:
E:\Study\Luban cat\3-Linux image\Debian system image\universal image (extboot)-applicable to all boards\ 20230712\LubanCat-rk3566\lubancat-rk3566-debian10-xfce-20230712_update\lubancat-rk3566-debian10-xfce-20230712_update.img
Note: Short circuit the MR point first, and then power on again. At this time, the software can recognize the MASKROM device (as shown above ), then disconnect the MR point, and then click the upgrade button to burn the
image. After successful burning, you can see the following print indicating that the system is running, but because the default screen uses HDMI, and the screen we connected is MIPI, so we can't see the display:

here use the serial port to log in to the system

to modify the screen to MIPI
Enter the "fire-config" command to enter the configuration interface:

enter the screen configuration:

select 1080P here:
Note: use the space bar to switch here (please see the following instructions: https://doc.embedfire.com/linux/rk356x/quick_start/zh /latest/quick_start/fireconfig/fireconfig.html)

select finish and exit, then enter the "reboot" command to restart:

you can see that the screen is displayed normally:

Luban cat modified the screen to adapt to MIPI

Rotate the screen to landscape

But now the screen is vertical, and our usage habit is horizontal. Enter the system and enter the following command:
"xrandr --output DSI-1 --rotate left"

You can see that the screen has become the horizontal screen we want
insert image description here
, but here we find that the touch is abnormal

Abnormal touch of Luban cat

Here use "fire-config" to modify the touch direction:
insert image description here

Rotate 90 degrees to the left:

After selecting finish, you can see that the screen returns to normal:

Luban cat touch is normal

Screen and touch direction modifications are permanently saved

But I tested and found that this method will return to the original vertical screen at the next restart. Here we need to find a way to save the screen settings! According to Lubanmao’s official statement, the solution to this problem is to
start a self-starting service. This service is used to modify the direction of the screen, although I think this is not the most authentic method, and then modify the "/etc/X11/xorg.conf.d/20-modesetting.conf" file according to the official reminder to permanently modify the screen and touch direction , the modified "20-modesetting.conf" file is as follows:

root@lubancat:~# cat /etc/X11/xorg.conf.d/20-modesetting.conf   
Section "Device"
    Identifier  "Rockchip Graphics"
    Driver      "modesetting"

### Use Rockchip RGA 2D HW accel
#    Option      "AccelMethod"    "exa"

### Use GPU HW accel
    Option      "AccelMethod"    "glamor"

    Option      "DRI"            "2"

### Set to "always" to avoid tearing, could lead to up 50% performance loss
    Option      "FlipFB"         "none"

### Limit flip rate and drop frames for "FlipFB" to reduce performance lost
#    Option      "MaxFlipRate"    "25"

    Option      "NoEDID"         "true"
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Device      "Rockchip Graphics"
    Monitor     "Default Monitor"
EndSection

### Valid values for rotation are "normal", "left", "right"
Section "Monitor"
    Identifier  "Default Monitor"
    Option      "Rotate" "left"
EndSection

Section "InputClass"
         Identifier "Goodix Capacitive TouchScreen"
         MatchProduct "Goodix Capacitive TouchScreen"
         Option "TransformationMatrix" " 0 -1 1 1 0 0 0 0 1 
EndSection

Among them, "Monitor" modifies the direction of the screen, and "InputClass" modifies the direction of the touch. The effect is actually the same as these two sentences:

xrandr --output DSI-1 --rotate left
xinput set-prop 9 'Coordinate Transformation Matrix' 0 -1 1 1 0 0 0 0 1

The final effect is as follows:

Luban cat screen and touch permanent save

There is another problem here, that is, the log will be output to the screen when booting. After the above modification, the desktop screen is reversed, but the screen is not reversed when printing the log. Here, modify "/boot/uEnv/uEnv. txt" file as follows:

uname_r=4.19.232
size=0x1000000
cmdline="earlyprintk console=ttyFIQ0 console=tty1 fbcon=rotate:3 consoleblank=0  
loglevel=7 rootwait rw rootfstype=ext4"

#dtoverlay=/dtb/overlay/rk356x-lubancat-pwm15-ir-m1-overlay.dtbo
"/boot/uEnv/uEnv.txt" 51L, 2575C written

The main thing here is to add the content "fbcon=rotate:3"
and the final effect is as follows:

Luban cat boot log screen rotation
