Automatic Startup of uShare on Jaunty Jackalope (9.04)

Issue: Because I am running wireless the ushare would always fail to load because it was loading to quickly before the wireless had a chance to reconnect with the router.


Solution

Created a simple script with the following lines:

sleep 10
ushare -x -c /sharepath

This makes it so that it waits 10 seconds before running the command. Then make the script executable.

sudo chmod -x scriptname

Add the script to the Startup Applications list:

System >> Preferences >> Startup Applications

create a new entry and point the command to the script you created.

Now reboot and test if it works, if it doesnt you may need to add more time to the sleep command in the script.

How to fix Desktop Effects aren't enable for intel integrated graphic in Jaunty

First, download Forlong's compiz-check

You can use this command to download it to your home directory:


wget http://blogage.de/files/9124/download -O compiz-check

Afterwards, you have to make it executable:

chmod +x compiz-check

And finally run it like this:

./compiz-check

If they output shows that Your intel graphic card is in the blacklist, this is the perfect solution for you.

Edit the compiz script file

sudo gedit /usr/bin/compiz

Then go down and look for blacklist, then add the # to take your intel graphic out of the blacklist.

Then the script should look like this

# blacklist based on the pci ids
# See http://wiki.compiz-fusion.org/Hardware/Blacklist for details
#T=" 1002:5954 1002:5854 1002:5955" # ati rs480
#T="$T 1002:4153" # ATI Rv350
#T="$T 8086:2982 8086:2992 8086:29a2 8086:2a02 8086:2a12" # intel 965
#T="$T 8086:2a02 " # Intel GM965
#T="$T 8086:3577 8086:2562 " # Intel 830MG, 845G (LP: #259385)
BLACKLIST_PCIIDS="$T"
unset T

Save, then restart

After reboot, go to System > Preferences > Appearance >Visual Effects
then tick on the middle or the last option.

Now your compiz should work back as normal.

How To: Add the Computer, Trash, and Home icons to the Desktop

This how-to will explain exactly how to add these icons to your desktop, in a completely graphical way.

1. You're going to follow this path in the Ubuntu panel:
Applications --> System Tools --> Configuration Editor.

2. If the above path existed, skip this step.

Sometimes System Tools isn't in the menu by default. It's simple to change by simply hovering your mouse over the taskbar, and Right-click --> Edit Menus. However, it is much easier to press
ALT + F2, and in the dialog box, copy/pasting

gconf-editor

3. On the left side of the configuration editor, follow this path:
Apps --> Nautilus --> Desktop.

4. Now, on the right side, select the checkboxes for "computer_icon_visible", "home_icon_visible", "trash_icon_visible", and whatever else applies to your wants/needs.

Howto enable ATI unsupported cards in Jaunty with full effets

The latest open source git drivers seem to have a lot of this fixed. While I'm sure you can wait until the next release when we get newer drivers, here is how to do this in Jaunty and get your system fixed now. Worst case scenario of doing this is that on your particular card all the cleanup hasn't been done yet, but on my x1200 this worked wonderfully.

Open up a terminal and run the following commands

sudo apt-get install build-essential autoconf automake libtool pkg-config git-core

sudo apt-get install libdrm-dev x11proto-gl-dev mesa-common-dev xutils-dev x11proto-xf86dri-dev x11proto-fonts-dev x11proto-randr-dev x11proto-video-dev x11proto-xext-dev x11proto-xinerama-dev x11proto-render-dev xserver-xorg-dev

git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-ati

cd xf86-video-ati

sudo ./autogen.sh --prefix=/usr --enable-dri

sudo make

sudo make install

Now restart your machine and you're using the new drivers. Try bumping up your visual effects to max and see what happens. If you're lucky like me, everything will work flawlessly. If not, then you may want to wait a couple weeks and try it again, but you're no worse off then you were before.

Ubuntu Cooling Tip

If you happen to have a clear fan with a blue led light, here is a helpful tip. Dust particles can build up on the intake of these fans and you will never be able to see it. I only discovered it because rising heat issues caused me to remove the side panel in order to use an exterior fan.


For whatever reason I happen to hold the the panel up in the air at a certain angle to the light and saw dust build up which looked in appearance to be similar to dryer lint which is removed from a clothes dryer. A few shots of compressed air to the inside of the fan to blow the buildup away from the intake does the trick. My 120mm fan is now happy again.

These are my after temps:
temp1: +29.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor
temp2: +16.0°C (low = +127.0°C, high = +127.0°C) sensor = thermal diode
temp3: -2.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor
cpu0_vid: +2.050 V

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +34.0°C (high = +78.0°C, crit = +100.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +34.0°C (high = +78.0°C, crit = +100.0°C)

Prior to cleaning my temps were 8-10 degrees higher across the board.
