Enable Anydesk on Linux

 By default, Anydesk doesn't work on Ubuntu as it uses a different display server than what is expected by Anydesk (it expects the traditional X11 rather than Wayland).

Dump this into a file, say, "fix_anydesk.sh", and then run it with

sudo bash fix_anydesk.sh

The script:

#!/bin/bash
# Check if the user has root privileges
if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 
   exit 1
fi
# Backup the GDM configuration file
GDM_CONFIG="/etc/gdm3/custom.conf"
if [[ -f "$GDM_CONFIG" ]]; then
    cp "$GDM_CONFIG" "$GDM_CONFIG.bak"
    echo "Backup of custom.conf created."
else
    echo "GDM configuration file not found."
    exit 1
fi
# Disable Wayland by uncommenting and setting the 'WaylandEnable' option to false
sed -i 's/#WaylandEnable=false/WaylandEnable=false/' "$GDM_CONFIG"
# Inform the user
echo "Wayland has been disabled. The system will use X11 instead."
# Restart GDM to apply the changes
systemctl restart gdm3
# Inform the user that the script is done
echo "Display manager restarted. You may need to log out or restart the system for changes to take full effect."

Pause a program which is using too much CPU

Sometimes your battery is running low and you need to pause a program without quitting it or force-quitting it, so that you can preserve battery but not lose the job that the program is doing. To do this,  Step 1. open a terminal Step 2. type:  ps ax | grep -i  "<program name>" so for example, if it's photoshop you need to pause, replace "<program name>" with "photoshop" Step 3. Next to the results on the far left you'll see a number, usually with 5 digits. E.g. 12345. Step 4. Type:  kill -STOP 12345 where 12345 are the numbers obtained in Step 2-3. Step 5. When you want to resume the program, type kill -CONT 12345 It should then continue to operate or run as usual without problems.
