GUIDE - Fresh Setup of Raspberry Pi 2 (B)


Recommended Posts

So little did I know that today the RPi 3 would be announced, However I got my RPi a few days back. Alot needs to be done to get it to work "properly" out of the box. Now I got the RPi with the 8GB Memory card from here.

 

https://www.modmypi.com/raspberry-pi/rpi2-model-b/raspberry-pi-2-model-b-new-and-8gb-microsd-card-bundle

 

Could not be happyer with ModMyPi. Extremely Fast Order Processing and Shipping.

 

So a few things I noticed (or rather what I have done with it so far...)

 

I am basing this from Raspian by the way, It works fine so far.

 

Anyway the first thing ANY Linux user should do is the obligatory.....

 

sudo apt-get update
sudo apt-get upgrade

 

Self Explantory....

 

Next ....

 

There are a built in set of tools to do a few "Advanced things" by all means play around with the other settings, However there is a specific option to make available ALL the disk space. Run this on the command line...

 

sudo raspi-config

 

I installed a few monitoring tools of my own preference. 

 

sudo apt-get install rpi-update htop iftop iptraf

 

If you are running it as a headless server, This implies you have SSH access and your Pi is shoved behind a <<Insert generic place to put your Pi>> Especially if your using it as a low powered server and not the GUI for any Media Center Apps etc. 

 

Remove the following....

 

sudo apt-get remove aspell desktop-base desktop-file-utils dictionaries-common dillo fonts-droid fonts-freefont-ttf fontconfig fontconfig-config galculator gnome-icon-theme gnome-themes-standard gpicview gsettings-desktop-schemas gsfonts gsfonts-x11 hicolor-icon-theme leafpad lightdm lightdm-gtk-greeter lxappearance lxde lxde-common lxde-core lxde-icon-theme lxmenu-data midori mime-support openbox omxplayer penguinspuzzle x11-common wpagui python3 python3-minimal python-pygame x11-common

turn off the swap space, the SD card might be slower so we dont need to use that.

 

sudo apt-get purge dphys-swapfile dphys-config

 

THIS alone is worth its waiting gold, A DNS Based Ad Blocker. I highly recommend it and I highly recommend you donate to the author. Copy and paste this command directly. 

 

curl -L install.pi-hole.net | bash

 

Update the RPI Firmware

 

sudo rpi-update

 

You should have a good basic system to do with whatever you want by now. 

 

Back up the System to an Image File so you can easily restore it. 

 

dd if=/dev/mmcblk0p1 of=/path/to/img/file/raspi.img bs=1M 

I installed transmission, Granted I mounted a USB hard drive to torrent from and to. But you can do whatever you like just be sure to mount it. These are the settings you need to change.

sudo apt-get install transmission-cli transmission-common transmission-daemon
sudo service transmission-daemon stop
sudo nano /var/lib/transmission-daemon/info/settings.json
**************************************************
*************Change the Following Settings***********

    • My father still uses a programme written in dbase3. Still manages to work with a little help from dosbox. 
    • Microsoft hides these secret Windows 11 performance boost settings available on every PC by Sayan Sen Windows enthusiasts often look for ways to extract as much performance out of their systems as possible, and it's often the case that they try and do so while trying to minimize the heat and power consumption. This is especially relevant in the case of mobile Windows PCs since laptops and notebooks tend to get hot and management of that heat and power is harder in such a form factor. As such users often turn to techniques like under-volting which can be used to squeeze out the maximum capabilities of a chip while also maintaining lowered power levels. There are official apps from AMD and Intel with the likes of Ryzen Master and XTU (Extreme Tuning Utility). While these are quite handy, most enthusiasts probably prefer to dig into the BIOS and play around with settings there like Curve Optimizer on Ryzen, which lets users set various frequency-voltage scaling values. These are essentially called P-States. If you are not familiar with them, Processor Power Management is done through Advanced Configuration and Power Interface (ACPI) P-states and C-states. While P-states or performance pwoer states handle CPU voltage-frequency scaling, C-states deal with CPU sleep states so that some of the CPU functions, which are not necessary at that moment, can be disabled. The P-states and C-states work together to make the processor run more efficiently. It helps the OS and apps determine which cores can be parked and which should be boosted. Of course not every user is an enthusiast or knows the technicalities and integrities of how things like overclocking or undervolting work. Thankfully for them Windows itself offers something pretty cool, though it is hidden by default on all systems. By default, Windows only has two P-States, "Minimum Processor State" and "Maximum Processor State." However, this can be changed with a Registry trick to expand the options under a secret "Processor performance boost mode" dropdown. This essentially enables the HWP or hardware P-States available on a device, and these are not controlled just by the OS itself as the underlying hardware gets involved too. In total there are five Processor Performance Boost Mode profiles that control how Windows requests and allows CPU turbo/boost behavior under the different power policies. They are: Disabled: In this mode, processor boosting is effectively turned off. The CPU will avoid entering turbo or boost frequencies and instead operate closer to its base frequency ceiling. This can significantly reduce power consumption and heat output, but at the cost of reduced burst performance and responsiveness in short workloads. Enabled: This is the standard behavior where boost functionality is allowed under normal conditions. The processor can opportunistically increase frequency when workload demands it, balancing performance gains with power and thermal constraints as managed by the system. Aggressive: Aggressive mode favors performance more heavily, allowing the CPU to enter higher boost states more readily and sustain them longer. This should in theory improve responsiveness under bursty or heavy workloads but increases power draw and thermal output compared to the default enabled behavior. Efficient Enabled: This mode still allows boosting, but with a stronger bias toward energy efficiency. The system attempts to use boost more selectively, avoiding unnecessary frequency spikes when the performance gain is marginal. Efficient Aggressive: This is a hybrid approach where boost is still performance-responsive, but the system continuously weighs efficiency more heavily than in Aggressive mode. It aims to deliver noticeable performance improvements while reducing wasted power in less demanding scenarios. Here's how to enable the Processor performance boost mode: Open Registry Editor: Press Win+R, type regedit, and click OK. Go to: HKLM\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\be337238-0d82-4146-a960-4f3749d470c7 (where HKLM stands for HKEY_LOCAL_MACHINE_) Modify the value of Attributes from 1 to 2 (you can find modify option by right-clicking) After that, exit Registry, you should now be able to see the new "Processor performance boost mode" dropdown menu: As you can see there are now five new P-States or CPPC states or power profile available that help define the boost mode processor setting on your PC. Wrapping it up here's a quick run-down of the settings as defined by Microsoft itself. Setting Description Disabled The corresponding P-state-based behaviour is disabled. Collaborative Processor Performance Control (CPPC) behaviour is disabled. Enabled The corresponding P-state-based behaviour is enabled. CPPC behaviour is Efficient Enabled. Aggressive The corresponding P-state-based behaviour is enabled. CPPC behaviour is Aggressive. Efficient Enabled The corresponding P-state-based behaviour is Efficient. CPPC behaviour is Efficient Enabled. Efficient Aggressive The corresponding P-state-based behaviour is Efficient. CPPC behaviour is Aggressive. Aggressive At Guaranteed Windows calculates the desired extra performance above the guaranteed performance level, and asks the processor to deliver that specific performance level. Efficient Aggressive At Guaranteed Windows always asks the processor to deliver the highest possible performance above the guaranteed performance level. In the next part we shall be comparing these settings to explore how much of a benefit or regression they can provide in terms of performance and power efficiency. If you decide to change the values on your system and are experiencing problems like crashes or an overheating PC, make sure to revert the steps back to the original state.
    • I think he means you haven't reviewed previous UFC games. Of course it doesn't matter... Every time you just report on something that involves the President even if just simply what happened you guys usually get accused of being anti-Trump. We live in fun times.
    • So how did you solve the problem? Disabling Secure Boot isn’t a solution.
