I wanted to try a light weight distro to see how my Acer Aspire Revo computer reacted, and what I had to do to get it installed.

Also why I picked this Linux distro, Performance boost (using cgroup, the notorious “4 lines of code better than 200″ in user-space.)

 

Installation:
1. Boot on to bootable DVD.
2. Go through the pages until you have the system installed.
Installation used around 3G’s of hard drive space. The Acer Aspire Revo seems to be even more responsive because of the light weight XFCE.

 


 

One problem I found after installation is the user I created didn't have a home directory so I could only login as the root user.

To fix the problem:

# userdel username

# useradd -m username

# passwd username

 

Give the user permission to SUDO

# usermod -g sudo username

 


 

To install the Nvidia drivers:

$ sudo su -

# init 1

Type root passwd

# /usr/local/bin/sgfxi will start the nvidia driver installation.

# reboot

Now I had to run this tool again to get the Video driver installed properly.

# /usr/local/bin/sgfxi

# reboot

 


 

To get the sound to go through the HDMI cable:

Create a /etc/asound.conf and add below:

 

pcm.!default {

type plug

slave {

pcm "hw:0,3"

}

}

ctl.!default {

type hw

card 0

device 3

}

 

Restart your computer.

Next go to Applications > Multimedia > Mixer and choose  Switches and only have check mark in IEC958 1, You should now have sound going through your hdmi cable to your monitor.

 


 

 

Hardware Sensors Setup:

# apt-get install lm-sensors if it isn’t installed.

# sensors-detect and hit enter on most of the questions except for this one,

Do you want to add these lines automatically to /etc/modules? (yes/NO) Type YES and hit enter.
After a restart you can now monitor the some of your hardware, I use conky for this. Make sure and go to Control Center -> Services -> Put a check mark on lm-sensors.
# sensors will show you all the hardware it is monitoring.

 


 

Error that I received and how to correct:

I received this message when booting up the system,

ACPI: resource nForce2_smbus [0x4d00-0x4d3f] conflicts with ACPI region IP2_ [0x4d00-0x4d04]
ACPI: resource nForce2_smbus [0x4e00-0x4e3f] conflicts with ACPI region SM00 [0x004e00-0x004e3f]

Edit your grub configuration file and add acpi_enforce_resources=lax
sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=”acpi_enforce_resources=lax quiet”
# sudo update-grub or sudo update-grub2

 


 

Install Flash and multimedia codecs:

# apt-get install flashplugin-nonfree

# installrestrictedmultimedia

 


 

Performance Adjustments I like to do:

Swap Tweak added to the sysctl.conf file. sudo sysctl -p
# Change the system on how it uses Swap Space (Default 60)
vm.swappiness = 10

# Don’t shrink the inode cache aggressively (Default 100)
vm.vfs_cache_pressure = 50

Network Performance Adjustments.
net.core.rmem_max = 4194304
net.core.wmem_max = 4194304

# Decrease the time default value for tcp_fin_timeout connection
net.ipv4.tcp_fin_timeout = 30
# Decrease the time default value for tcp_keepalive_time connection
net.ipv4.tcp_keepalive_time = 1800
# Turn off the tcp_window_scaling
net.ipv4.tcp_window_scaling = 0
# Turn off the tcp_sack
net.ipv4.tcp_sack = 0
# Turn off the tcp_timestamps
net.ipv4.tcp_timestamps = 0

Change I/O Scheduler: Seems to give a better feeling on the desktop, no hesitation when doing big copies, backups etc, may affect other workloads on the system.

sudo nano /etc/rc.local
test -f /sys/block/sda/queue/scheduler &&
echo deadline > /sys/block/sda/queue/scheduler

File System Tweak
This can help with reads and writes to hard drives, SSD drives may really like this.
# sudo nano /etc/fstab and add below.
tmpfs /tmp tmpfs defaults,noatime,mode=1777 0 0
