Installing Selenium in Termux the right way

pip install selenium==4.9.1
yes | pkg install x11-repo -y
yes | pkg install tur-repo -y
yes | pkg install chromium -y

Ubuntu in termux over noVNC over hotspot.
Yes I AM GOING TO forget this so I am writing here

pkg up && pkg install git wget -y && git clone --depth=1 https://github.com/modded-ubuntu/modded-ubuntu.git && cd modded-ubuntu && bash setup.sh

# Follow the instructions of the setup.

# turn hotspot on, then run this, swlan0 is hotspot interface on OneUI, unlike aosp which is wlan1

sudo ip address add 1.1.1.1 dev swlan0

# execute the new bin we have:

ubuntu

git clone https://github.com/novnc/noVNC.git

# first we clone NoVNC
git clone https://github.com/novnc/noVNC

# then run vncserver
dbus-launch vncserver :1 -geometry 1080x2408 -depth 24 -zliblevel 0 -name modded-ubuntu -xstartup /usr/bin/xfce4-session

# although vncstart command exists, sometimes it goes to 5902, read automation below.

./noVNC/utils/novnc_proxy --vnc localhost:5901 --listen 1.1.1.1:1111;}
# Now should give a link, any device connected to your hotspot should be able to navigate to that link

# in termux, modify /data/data/com.termux/files/usr/bin/ubuntu, and append this to first line

su -c "ip address add 1.1.1.1 dev swlan0"

# to optioanally check for hotspot

[[ -z $(ifconfig | grep swlan0) ]] && echo "hotspot is off blud"

# in ubuntu, edit this file: /usr/local/bin/vncstart and define device as :1 so port can always be :1

dbus-launch vncserver :1 -geometry 1080x2408 -depth 24 -zliblevel 0 -name modded-ubuntu -xstartup /usr/bin/xfce4-session

# in ubuntu .bashrc, append this

host() { vncstart; ./noVNC/utils/novnc_proxy --vnc localhost:5901 --listen 1.1.1.1:1111;}

# now you can open termux, write "ubuntu", in ubuntu you write "host", and it is done.
