Fedora 14 Laughlin on Laptop

Fedora 14 Laughlin on Laptop



Firstly, to use Fedora you have to be quite comfortable with GNULinux Operating System in general.
What Fedora offers over other GNULinux
(Needless to say Mac OS X sucks with the price tag and the lack of new useful features):

1)It is cutting edge, new features are introduced into Fedora frequently unlike "Rock Solid" Distro like Debian Stable.

2)Fedora runs out of box rather nicely because it is updated, new hardware have a good chance of running smoothly without recompiling hardware kernel driver modules.

3)Fedora developers are the people working on GNOME hence if you like to use GNOME as the desktop manager, Fedora is a good choice.

4)Ubuntu IMO tends to be too hand-holding hence it is rather filled with GUI centric applications, in contrast Fedora runs fast and light.

5)Being a supported distro, it offloads the task of package recompiling to the people maintaining it hence you do not have to constantly recompile new packages when released like Gentoo.

Actually I did try to think of ways how to make a simple guide on how to install Fedora on the laptop but I did too many tricks to get it working such that I dont think it is suitable for the mostly GUI oriented users.

However I will share my observations on Fedora Laughlin.

There are a few small bugs regarding GNOME and the rendering of display IF YOU use the default GTK themes I had to use the Solaris Nimbus theme or the Nodoka theme as a workaround.

Next I recommend you use the Nvidia Developer Driver 260.19.14 for Linux instead of the WHQL because it provides very aggressive power saving settings I do notice a slightly improvement in battery life.

I am glad to say that suspend/resume works with the above combination.

You have to append nomodeset and vga=318 to the end of the kernel line to get a nice Plymouth splash and WITHOUT removing nouveau driver as a fallback.

To change cursor you have to edit the "default" text file in /usr/share/icons to point to the cursor theme you want to use.

You can use the same tweaks in the OpenSUSE Guide.

By default, all filesystems are now mounted with relatime enabled. To suppress this feature across an entire system, use the boot parameter default_relatime=0. If relatime is enabled on a system by default, you can suppress it for any particular file system by mounting that file system with the option norelatime. Finally, to vary the default length of time before which the system will update a files atime data, use the relatime_interval= boot parameter, specifying the period in seconds. The default value is 86400.

The fact that the rpmfusion drivers sucks means that it is difficult for GUI people to install it therefore I gave up on writing a guide.

However those who are quite the superuser and wish to try Fedora can still ask me for some opinions (not a expert though).

For Users with Nvidia Graphics Adapters

1)Grab the install media, use unetbootin to convert the bootable iso to bootable thumbdrive.
For users with internet the Live CD x86 (32bit) or the x86_64(64bit) will do.
The full DVD includes package it is for users who do not have access to internet hence needs to install the packages by DVD Media.
2)Format the disk partition as instructed, make sure there is empty space on the harddisk to install Fedora to.

3)Enable Sudo and add your user account as wheel.
Open Terminal:
#su
#visudo 
Press i to enter insert mode.
Change 
#%wheel  ALL=(ALL)       ALL
To
%wheel  ALL=(ALL)       ALL
Press Esc" then ":wq" to save and exit.
Go to Main Menu -> System -> Administration -> Users & Groups
Select your User Account then Properties go to Group Tab then check "Wheel".

4)Adjust the boot entry in /boot/grub/menu.lst by opening terminal entering:
sudo gedit /boot/grub/menu.lst

Comment out Hidden Menu
#hiddenmenu
Set Default to the default boot entry number (eg 0=First Boot Entry, 1=Second Boot Entry etc)
Add the following behind the kernel boot parameters:
rhgb quiet nomodeset default_relatime=0 vga=0x318

More VGA Settings can be found here, however the value above 0x318 which is for 1366X768 resolution is strangely not found in the site above.

You can edit the title of your Windows Boot Entry to
title Windows 7

Example (Highlighted Notable Changes in Blue):
default=1
timeout=3
splashimage=(hd0,4)/grub/splash.xpm.gz
#hiddenmenu
title Fedora (2.6.35.6-48.fc14.x86_64)
    root (hd0,4)
    kernel /vmlinuz-2.6.35.6-48.fc14.x86_64 ro root=UUID=0ee4372e-2c84-4238-b822-d83759547d4b rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=us rhgb quiet nomodeset default_relatime=0 vga=0x34D
    initrd /initramfs-2.6.35.6-48.fc14.x86_64.img
title Windows 7
    rootnoverify (hd0,0)
    chainloader +
5)Run all updates
Go to Main Menu -> System -> Administration -> Software Updates
Reboot and boot into the latest Kernel

6)Managing Kernel Entries
Fedora dependency is good so to remove older kernels:
Go to Main Menu -> System -> Administration -> Add/Remove Software.
Search for Linux and uncheck the "Filter" "Show only Newest package"
Find the old kernel then uncheck and apply to uninstall it.

7)Installing the Nvidia Drivers
Download the latest Nvidia Driver For Linux from http://developer.nvidia.com/object/cuda_3_2_toolkit_rc.html

8)Install the development tools as follows:
You need to have the following installed

______________________________________________________________________________

Chapter 2. Minimum Software Requirements
______________________________________________________________________________



Software Element Min Requirement Check With...
--------------------- --------------------- ---------------------
Linux kernel 2.4.7 `cat /proc/version`
XFree86/X.Org 4.0.1/6.7 Xorg -version`
Kernel modutils 2.1.121 `insmod --version`


If you need to build the NVIDIA kernel module:

Software Element Min Requirement Check With...
--------------------- --------------------- ---------------------
binutils 2.9.5 `size --version`
GNU make 3.77 `make --version`
gcc 2.91.66 `gcc --version`
glibc 2.0 `ls /lib/libc.so.*` 
 
Use terminal to run the commands underlined if you are missing any packages 
you need to install it with root permission either using sudo or su.
Make sure you have the kernel headers required installed.
Run in terminal:
sudo yum install kernel-devel
9)Reboot upon seeing the grub entries scroll to the kernel press e on it and append init 3 to it.
10)To install login in then type
$su
#cd Downloads
# sh devdriver_3.2_linux_64_260.19.14.run
The filename of the driver maybe different from the above.
Accept and press ok when you see ok.

To uninstall run:
$su
# sh devdriver_3.2_linux_64_260.19.14.run --uninstall

Reboot with the command
#init 6
11)Adjust the xorg.conf file by opening the terminal
$sudo gedit /etc/xorg.conf

Adjust to look like the below:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 260.19.14  (buildmeister@builder103.nvidia.com)  Mon Oct 18 21:52:42 PDT 2010

12)Install the Nimbus GTK Theme as a workaround to that lag bug:
$sudo yum install nimbus-theme-gnome
Change to the Nimbus theme

13)Install Cairo Dock:
$sudo yum install cairo-dock

14)Install Java
$sudo yum install java-1.6.0-openjdk-plugin

15)Change the cursor in Fedora 14

16)Remove icons from GNOME Desktop

17)Install Global Menu:
$sudo yum install gnome-applet-globalmenu

18)Install OpenOffice (let the dependencies resolve themselves):
$sudo yum install openoffice.org-calc openoffice.org-writer openoffice.org-draw openoffice.org-impress

19)Install GIMP (Powerful OpenSource Photoshop alternative)
$sudo yum install gimp

20)Adding tmpfs to /tmp
Add this line to /etc/fstab to make /tmp folder a RAMDisk so /tmp will be automatically cleared during shutdown.

tmp              /tmp            tmpfs    defaults   0 0
noatime is already implemented by the default_relatime=0 boot parameters.


21)Disable the scale when you move the cursor to the top right hand of the screen:
$sudo yum install ccsm compiz-backend-gconf
Then access compizconfig setting manager and disable the scale plugin -> initiate Window Picker

22)Install Chromium
Flash for Chromium

23)Install gsynaptics to enable 2 finger scroll. It works in Fedora 14! Sometimes it works sometimes it doesnt.
$sudo yum install gsynaptics

24)Install Systemd and switch to it instead of upstart.
$sudo yum install systemd
Then append init=/bin/systemd to the end of the kernel parameters.
I notice some speed up in suspend and resume operations but then it might just be me.

Once you get the hang of installing by terminal you are somewhere there
You may want the following software as well:
Adobe Flash
Skype
To fix the Skype Video you need to change the launcher command as shown below:

Change it to:
sh -c export XLIB_SKIP_ARGB_VISUALS=1 && LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so /usr/bin/skype

Windows Fonts

There you go! If you still need GUI for every step Fedora is probably not for you. You should try Ubuntu or Mint or OpenSUSE instead.
Feel Free to leave comments if you feel that something is omitted.

Fix Notebook Laptop Keyboard

Fix Notebook Laptop Keyboard


Damage to the notebook/laptop keyboard can be grouped into several types

  1. When the notebook is turned on, the sound tiit ... tiit ... tiit ...
  2. When a button is pressed once, the button will appear continuously. Example, when pressed the "D" one time, appeared ddddddddddddddddddddddddddd ....
  3. When pressed a button, the screen does not show anything. Example, when pressed the "F", the screen does not show anything.
How to remove the notebook keyboard
How to remove the notebook keyboard
1. Push the panel to the top
2. Pull up the keyboard
How to remove the notebook keyboard
1. Remove the top cover
2. Open the bolt keyboard

Fix Notebook Keyboard
1. After the keyboard is removed, clean the keyboard cable with a pencil eraser, do it vertically
Fix Notebook/Laptop Keyboard
 2. Release all keys. Do it carefully
Fix Notebook/Laptop Keyboard
 3. Arrange all the keys in the order
Fix Notebook/Laptop Keyboard
 4. Clean the keyboard
Fix Notebook/Laptop Keyboard
 5. Attach the keyboard, then turn on the notebook
Fix Notebook/Laptop Keyboard
 6. The observation
  • When the notebook / laptop is turned on, the sound of tiit.......... (video)
  • When the "D" is pressed once, appears ddddddddddddddddddd (video)
  • When the "," or "<" is pressed once, appears ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, (video)
  • When the "F" is pressed, the screen does not show any or the "F" does not work (video)
Conclusion
When the notebook / laptop is turned on, the sound of tiit ..... This is because, there is damage to the "D" "," "<" "F" (the observation number 2, 3, 4)

Fix Notebook/Laptop Keyboard
Rubber buttons

7. Solution
For the "D" = remove rubber buttons, and then plug it back without using adhesive / glue (see video)
For the "F" = remove rubber buttons, and then reinstall using the adhesive / glue.
Slide the rubber position, until the right position, then stick with glue
For the "," or "<" = remove the rubber button, then plug it back without using adhesive / glue (see video)
Fix Notebook/Laptop Keyboard
 8. Turn on the notebook and do the test. If no damage is found, your keyboard is back to normal, but when the notebook is turned on the sound still tiit ... tiit ... tiit ..., meaning that there is an error in the keyboard. Search and find a broken button, do the repairs as the instructions above.

There are three characters damage the notebook keyboard
  1. When the laptop is turned on the sound, tiit ... When entering the windows, keyboard error.
  2. When the laptop is turned on there was no sound, tiit ... When entering the windows keyboard error.
  3. When the laptop is turned on no sound tiit ... When entering windows normal keyboard, and when worn typing, the keyboard error.
In principle, we must find the button that was damaged, and do the repairs in a way
  1. Cleaning the keyboard from dirt
  2. Shift the position of keyboard so that the rubber is in the right position, then stick with glue (in the case of the "F")
  3. Remove and reinstall the rubber keyboard, without using glue (in the case of the "D" "," "<")
I hope this information useful. Thanks

Crazy Stuff I Did To Lower The Temperature Of The Laptop

Crazy Stuff I Did To Lower The Temperature Of The Laptop


Here is the deal:
You have encounter high temperatures especially during gaming.
You contacted the Repair Centre.
They told you to update the BIOS (usually the fix include making the fan spin more often).
You have sent the laptop back and forth until you have given up.

Finally the warranty run out and you can only depend on yourself.

Below are the following mods you can do.


For me I did the following:

Note: Most steps require dismantling of the system it will help with expert supervision and googling and down loading of service manual to dismantle it.

  • Throw away the thermal pad on the GPU and use Arctic Silver 5 instead
  • Remove the original CPU thermal paste and use Arctic Silver 5 instead.
Arctic Cooling MX-2
Arctic Silver 5

  • Remove and throw away the "air filter" below the Laptop bottom cover to allow better air flow (I decided to do this after realizing this is the only part you can feel that air actually goes into the laptop, hence obstructing it restricts air flow hence remove it)
  • Sand the surface of heatsink which comes into contact with the GPU or CPU chip, using FINE SILICON CARBIDE PAPER
  • Sharpen the edges of the air vent casing (I got this inspiration by observing other Acer Aspire Laptop (Aspire 4935G) models, I noticed their vent size is gigantic compared to the vent size of this particular model hence it could be one of the gaming overheating factors. The new Acer Aspire 4736ZG Series Air Vents actually have even bigger holes than 4935G!)
Original (Top view)

Modified (Shave the vent corners)(Top view)

Actually the best cutting should be a wing shape pointing into the chassis.
The smaller the air drag the better.


Wikipedia

Not sure how much of this helps
But now my gaming temperatures fall below 90 degrees (around 85) and my idle temperature falls below 60 degrees (around 55) for the GPU.

Check out my recently modded laptop thermal exhaust:

Compare it to your original Aspire 4530 exhaust spot any difference?
Originally it has 16 dividers I cut out 8 of them so it looks like this.

5) I added Aluminium tape to bridge the laptop bottom chassis which is made out of metal to the heatsink.


Aluminium Tape

How I did it.

I rolled and flatten out one piece of Aluminium Tape to thicken it made sure it stucked in between the two interface without falling off (but not too tight).
Then I stick a tape over the heatsink and the chassis for better conduction.
The lowest temperature is now under 55 degrees hence it pretty much works.

6) UnderVolt the AMD Processor

7) Set the Graphics Mode to performance.
