Transform Windows keyboard to Ubuntu
Transform Windows keyboard to Ubuntu
Why should there be a windows key on a Ubuntu computer ?
This question has bothered many Linux users, so here�s what you can do.
With a nail sandpaper, sand the top of the key until you see no image there (careful not to damage the key). |
Alternative: if you use a transparent nail polish on the key and remove it using acetone (after a while), the image can be erase easily. |
After remove the image, pass nail polish on the key. |
Print the image you want to put on the key on a normal sheet (i made it 0,6cm x 0,6cm). |
Pass transparent nail polish on both sides of the sheet over the image. The sheet will become a little �plastic�. |
Cut the image carefully, using a knife. |
Paste the image on the key (you may paste with the nail polish) and pass more nail polish to fix it and protect. |
And your done. |

Ubuntu Logitech diNovo Edge Bluetooth Wireless Keyboard Part 2
Ubuntu Logitech diNovo Edge Bluetooth Wireless Keyboard Part 2
I reported on problems with Ubuntu Logitech diNovo Edge Bluetooth Wireless Keyboard, and now in Ubuntu 11.10 Oneiric and Ubuntu 12.04 Precise the problem resurfaces each time you do a fresh install or Distribution Upgrade. But the solution is slightly different than before.
Update: The problem appears in Ubuntu/Kubuntu 12.04 Precise also, but the solution is the same.
This solution is using for the Logitech diNovo Edge in Ubuntu/Kubuntu. Symptoms are the bluetooth-device-manager kept prompting me to connect to the device but nothing I did ever worked.
Here is the solution / fix for getting the keyword to work. The source for this information is here.
The problem is in the udev rules. In 11.04 there was a special line in /lib/udev/rules.d/70-hid2hci.rules for Logitech devices that started with KERNEL=="hidraw*".
These seem to be missing in default configurations. This fix adds this line into another file instead which makes things work.
Edit the file: /lib/udev/rules.d/##-bluez-hid2hci.rules (where the ## is the number on your system. Just search for the keywords bluez-hid2hci.rules in the /lib/udev/rules.d/ directory. For example, on my system in Ubuntu 11.10 it was number 62 and on Ubuntu 12.04 is was 97.)

Keyboard Shortcuts
Unity comes equipped with easy and useful keyboard shortcuts. Keyboard shortcuts by pressing combinations of keys can be used to handle applications, windows and graphical user interface without using the mouse. Using keyboard shortcuts may seem a bit awkward at first, but the key combinations are easy to remember and once you get used to, it helps us to handle our computer with high speed without having to take your hands off the keyboard to hold the mouse.Starter

Ubuntu Logitech diNovo Edge Bluetooth Wireless Keyboard
Ubuntu Logitech diNovo Edge Bluetooth Wireless Keyboard
I use the Logitech diNovo Edge in Ubuntu/Kubuntu and I love it. When I installed Kubuntu 10.04 Lucid, this wireless keyboard failed to work. The bluetooth device manager kept prompting me to connect and pair the device with a PIN but nothing I did ever worked.
UPDATE/EDIT: This problem has been reported in version dating from 10.04 to 11.04. This solution works for those, but there is a slightly different solution for 11.10.
Here is the solution / fix for getting the keyword to work. The source for this information is here.
Edit the file: /lib/udev/rules.d/70-hid2hci.rules
(If you need help editing a file, see bottom section.)
Change this line:
# Logitech devices
KERNEL=="hiddev*", ATTRS{idVendor}=="046d" , ATTRS{idProduct }=="c70[ 345abce] |c71[34bc] ",
RUN+="hid2hci --method=logitech- hid --devpath=%p"
to
KERNEL=="hidraw*", ATTRS{idVendor}=="046d" , ATTRS{idProduct }=="c70[ 345abce] |c71[34bc] ",
RUN+="hid2hci --method=logitech- hid --devpath=%p"
I have made the changed sections BOLD. I also turned bluetooth off from the icon in the system tray.
After making this change, I turned on my wireless keyboard, unplugged its bluetooth dongle, plugged it back in, paired the keyword with the dongle, and a few seconds later it worked. I did not even have to reboot.
HOW TO EDIT THE FILE (for those who need help with this stage)
New users to Linux may have trouble editing text files at first. Ill try to be simple, and this guide is for people using Gnome or KDE.
The simplest way is using a user friendly program. In Gnome (which is normal Ubuntu), the default text editor is gedit. In KDE (in Kubuntu) it is Kate. Also, this is a protected system file, so you need to use special Administrator privileges before you can edit it. Dont worry. This is simply.
KDEIn KDE, you need to find the "Run Command" option the Application menu. (The App menu is usually in the lower left-hand corner, with a colorful K-button.) In KDE4s new menu style, the "Run Command" is (currently) under the Computer section, near the top of the small list. Find the option and click it.
In the input box that displays, copy/paste the this command into it and press enter:kdesu kate /lib/udev/rules.d/70-hid2hci.rules
The kdesu program tells the system you want to run the text editor (kate) with Admin access. You will be prompted for your individual user password, which you enter. Then kate should open with a file ready for you. (This is the /lib/udev/rules.d/70-hid2hci.rules file which we told kate to open for us.) If this file does not open, you can open it manually by going to menu File -> Open... and then navigating to the / root directory, down to lib and so on until you find the file 70-hid2hci.rules.
Edit the file as directed earlier in this article. Save the file, close the file (menu File -> Close), and then finally exit Kate.
GNOME
In the input command window that displays, copy/paste the this command into it and press enter:
gksu gedit /lib/udev/rules.d/70-hid2hci.rules
The gksu tells the system you want to run the text editor (gedit) with Admin access. You will be prompted for your individual user password, which you enter. Then gedit should open with a file ready for you. (This is the /lib/udev/rules.d/70-hid2hci.rules file which we told gedit to open for us.) If this file does not open, you can open it manually by going to menu File -> Open... and then navigating to the / root directory, down to lib and so on until you find the file 70-hid2hci.rules.
Edit the file as directed earlier in this article. Save the file, close the file (menu File -> Close), and then finally exit gedit. You can close the Terminal also.
Hope that helps.
