The installation went great on my samsung n150 plus netbook, but my HP DV7 laptop was a different story.

Fix White Screen of Death (ati video cards)

Fix Stuck Splash Screen and X Crash During KDE Startup

Fixing Missing SSH Keys

sudo rm /etc/ssh/ssh_host_*
sudo ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key
sudo ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key
sudo ssh-keygen -t rsa1 -f /etc/ssh/ssh_host_rsa1_key
sudo /etc/init.d/ssh reload

Fix Missing libkontactinterface.so.4

If you get this error message:

kmail: error while loading shared libraries: libkontactinterface.so.4: cannot open shared object file: No such file or directory

Then do this to fix it:

 
 
 
 
sudo apt-get --reinstall install kdepimlibs-dbg
 
 
 
 

Fix Lockups When Minimizing or Maximizing Windows (ati video cards)

First you need to prepare the sources.  This is done like this (see the next problem below too):

prepare-kernel-sources
cd /usr/src/linux
cp -rf include/generated/* include/linux/

Then download and install the ati fglrx binaries for either 32 bit or 64 bit from here (specific for your video card):
http://support.amd.com/us/gpudownload/Pages/index.aspx

Install the drivers. Configure the video card to use fglrx driver.

Fix prepare-kernel-sources

If you run `sudo prepare-kernel-sources` you will realize the script has an error. Not only does it have an error, but it also has other issues, like “WARNING: Symbol version dump /usr/src/linux-source-2.6.38/Module.symvers”

To fix this, edit the file /usr/bin/prepare-kernel-sources with your favorite editor, mine is vi….

Go to the line that has `cp /boot/` and change that to `# cp /boot/` to comment it out.

On the next line add:

sudo cp /usr/src/linux/.linux /boot/config-${VER}

 

Here is my entire modified so it works prepare-kernel file:

#!/bin/bash
echo "if you are compiling a custom kernel, what do you want appended to the name?"
echo "i.e., if you want custom.1, then your kernel will be called linux-2.6.38-custom.1"
echo "it must contain a period followed by a number"
read CUSTOM_NAME
 
VER=`uname -r`
echo "[*] apt-getting linux-source..."
sudo apt-get install linux-source
cd /usr/src/
echo "[*] extracting sources, please wait"
sudo tar jxpf linux-source-${VER}.tar.bz2
echo "[*] doing stuff..."
sudo rm -rf linux
sudo ln -s /usr/src/linux-source-${VER} /usr/src/linux
cd /usr/src/linux
sudo zcat /proc/config.gz > .config
#cp /boot/
sudo cp /usr/src/linux/.config /boot/config-${VER}
sudo make oldconfig
sudo make scripts
sudo make prepare
make KDEB_PKGVERSION=${CUSTOM_NAME} deb-pkg
sudo ln -s /usr/src/linux /lib/modules/${VER}/build
echo "[*] tada!  Done building kernel and dpkg image"
 
echo -e "this is the differences between your running kernel config and the new kernel config.\n\nYou should review them closely before installing the kernel and rebooting."
diff /boot/config-${VER} /usr/src/linux/.config
 
while true; do
    read -p "Do you want to install the kernel?" yn
    case $yn in
        [Yy]* ) dpkg -i ../linux-image-${VER}_${CUSTOM_NAME};;
        [Nn]* ) exit;;
        * ) echo "Please answer yes or no.";;
    esac
done
