Fedora Tips & Tricks

This is a followup post to ealier post on Fedora

• Mount folders without requiring passwords

Usually, mount folder permission is only available to root user. In order to allow this for normal user, we need to add a policy rule for polkit

sudo vi /etc/polkit-1/localauthority/50-local.d/10-mount-without-password.pkla

[storage group mount override] 
Identity=unix-user:madhur 
Action=org.freedesktop.udisks2.filesystem-mount;org.freedesktop.udisks2.filesystem-mount-system 
ResultAny=yes 
ResultInactive=yes 
ResultActive=yes

• Similarly, if you want to allow normal user to manage systemd units

/etc/polkit-1/localauthority/50-local.d/service-auth.pkla

[Allow yourname to start/stop/restart services]
Identity=unix-user:madhur 
Action=org.freedesktop.systemd1.manage-units 
ResultActive=yes

• Set a default font in Fedora Linux

<?xml version="1.0" encoding="UTF-8"?>
<match target="pattern">
   <test name="family" qual="any">
      <string>monospace</string>
   </test>
   <edit binding="strong" mode="prepend" name="family">
      <string>JetBrains Mono</string>
   </edit>
</match>

• Change the CPU governor policy for maximum performance

echo "performance" | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

• Auto login user through LightDM

/etc/lightdm/lightdm.conf.d/12-autologin.conf

[SeatDefaults]
