I bought new raspberry pi 3 b+ and using etcher i installed kali linux ARM image file on sd card 32 gb . At first boot up everything looks good kali starts with graphical login window and i did all first thing UPDATE , UPGRADE , DIST-UPGRADE and after that i downloaded a library from github for the KUMAN 7 inch touchscreen 800?400 LCD 7 B . When i gave the command to load the settings for KUMAN 7 inch screen kali linux restarted and from that point i never see graphical login window now everytime i start kali linux it takes me tty type login where it asks me username and password but i don't see anything graphical now it's all console type

Someone help me to solve this so i can use again kali linux in graphical mode thx
