Problem: A Motorola phone (specifically the W755 and similar series) will not charge on USB either ever, or after reformatting a computer. Applies to many Motorola phones, including Motorola Android, Motorola OS, Motorola Linux OS, Motorola iDEN, Motorola Symbian/UIQ, Motorola Windows Mobile® and Motorola i-mode devices, Motorola XOOM™ tablet.

Cause: Older Motorola phones will not charge while they have a data connection active. If you were able to charge before and reformatted, you probably no longer have the correct drivers that would allow your phone to charge.

Solution: Download the Motorola Helper Software so that the phone will know to charge rather than just use a data connection. (Note from the author: I know this sounds preposterous, but Motorola phone USB charging is messed up stuff).

Download the MotoHelper – this will choose the correct driver for you and get you going faster.

Problem I: Unable to locate a driver for Citizen GSX140 printers (24-pin color DOT Matrix printer)
Solution: GSX 140 printers, as well as many other dot-matrix printers, actually emulate Epson printers. You can use the Epson LQ 2550 driver for the GSX140 and many other similar Citizen printer series. All features (including color printing) will still work.
Problem II: I can’t find the Epson LQ 2550 printer driver

Cause: Windows does not automatically include the driver and requires it to be obtained via. Windows Update.

Solution: Go to the Control Panel “Add Printer” wizard.
If you are installing a network printer, do not select “Use a Network Printer”.
Complete the installation as if you were going to install a local printer  on the LPT port (selecting any port at this stage is fine).
When you reach the driver selection screen, press the “Windows Update” button. Window will begin downloading hundreds of legacy drivers — included is the Epson LQ 2550. This will take awhile on slower connections and cannot be paused or stopped.
If you were installing the printer as LPT or as USB with an LPT converter, you can continue. If you were meaning to install a Network Printer, cancel the wizard  and start it again for network printers. You can now select the LQ 2550 driver under “Epson” manufacturer printers.

An alternative is to use the Epson LQ Series 2 (136) driver, but this will only support 180×180 printing in black and white.

Reworded: For Citizen GSX 140 series Printers, use the Epson LQ 2550 driver.
If you need the Epson LQ 2550 driver, but it is not available, use the Epson LQ Series 2 (136) driver which will not support high resolution or color (also works for Citizen GSX 140)
Many other dot-matrix printers use the same drivers.

One important note! The LQ Series 2 (136) driver will not support color printing or high resolution printing. We are currently investigating as to why our trial run of this yielded only black & white printing which may have been from a variety of causes (wrong driver, our CUPS server, the Windows computer connected, etc).

Description: Ubuntu 11.04 BETA I seems to not detect or acknowledge the presence of any wifi card, wifi is not listed on the wireless menu, and ifconfig/iwconfig do not list a wlan device. Commands such as   rfkill list  show the device, but as blocked.
WiFi light will not turn on with key command, either.

Problem: Once again, the Ubuntu team has provided incorrect default drivers for Broadcom devices. These directions will only help you to  gain some functionality from your wifi device. The wifi may not work to its full potential.

Solution: Navigate to Additional Drivers. To get here from Ubuntu 11.04, click on the power button on the desktop in the upper right hand corner, and click “System Settings”. Locate “Additional Drivers” under the Hardware category.

Remove/deactivate the Broadcom STA Wireless driver. Restart the computer.

Log in, and open a terminal. Then run:

sudo apt-get install firmware-b43-installer

Restart the computer again.

You should notice that your WiFi light has turned on.Wireless can not be enabled and disabled from the Network menu (next to the system clock).

A note: Usability of the card may be poor due to having “sketchy” drivers installed. The particular driver installed will work for most Broadcom cards, but may not offer the full features your card may typically have.

Please comment and share how well this worked for you (if at all) and any other solutions you may come across.

Details: Ubuntu 11.04 BETA I fails to allow use of Unity Desktop when a nVidia GeForce Go 7300 is used.

Problem: The new nVidia driver introduced with Ubuntu 11.04 is not actually compatible with said card.

Solution: Simple.
First, to get into some kind of desktop, get back to the Ubuntu login screen (you can NOT get the desktop to un-freeze, you may have to force shutdown or do some other complicated things).
At the bottom of the login screen, select a different desktop to use. The drop-down box is set to Ubuntu as default. Instead, select “Ubuntu Classic (no effects)” and log in.

Your desktop should now load with the traditional Gnome interface. Don’t walk away just yet, as full functionality is just a moment away:

Open (under System) “Additional Drivers”, find whichever nVidia driver is installed and remove/deactivate it. Restart your computer.

Login and open Additional Drivers again, and install/activate the driver named “Expiremental 3d Support for  nVidia cards”. Restart your computer, and change the desktop in the login-screen drop-down box back to Ubuntu.

Ubuntu 11.04 with the Unity desktop should load successfully.
