Web-E's questions

I am trying to run flashtool (flashing utility for android phones) in ubuntu. Already setup java and appropriate environment

On execution the following error comes up

rajeswar@WebE-PCl:~$ FlashTool/FlashTool
Not running as root but Sony/SonyEriccson Vendor ID found on your udev rules
if Flashing didn't work well, run flashtool as root
libusb.LibUsbException: Libusb not found. Minimum libusb version is 1.0.15. It can be downloaded on http://www.libusbx.org
    at libusb.UsbSystem.initSystem(UsbSystem.java:28)
    at libusb.UsbSystem.<init>(UsbSystem.java:15)
    at linuxlib.JUsb.init(JUsb.java:21)
    at gui.Main.initLinuxUsb(Main.java:47)
    at gui.Main.main(Main.java:34)

So I downloaded the latest version from http://libusbx.org/, after extraction executed

./configure && sudo make && sudo make install && sudo ldconfig.

It executed successfully & installed to /usr/local/lib/.. But the error keeps coming..

This is output of sudo ldconfig -vp | grep usb

Any idea how to fix it?

I think the problem lies in these lines

export LD_LIBRARY_PATH=./x10flasher_lib/linux/lib64:$LD_LIBRARY_PATH
ln -sf libusbx-1.0.so.0.1.0 ./x10flasher_lib/linux/lib32/libusbx-1.0.so

How to setup an Access Point (AP) mode Wi-Fi Hotspot?

Point to be noted: Wireless access points aren't the same as ad hoc networks. They differ significantly. In short, ad hoc networks aren't supported on newer devices and most Android, Windows Phone and Blackberry devices (and maybe iOS devices too), whereas AP mode Wi-Fi hotspots are. To get an idea about AP mode hotspots, ad hoc networks and their difference, refer to this Wikipedia page.

Does 12.04 need graphics drivers for NVidia?

I have an old system which is not connected to internet. The computer specification as below,

• Intel Dual Core
• 3GB RAM
• Mobo : Asus P5N73- AM

Now if you see the specification of mobo, you can see the chipset is NVIDIA GeForce 7050/nForce 610i and VGA card is Integrated GeForce 7050 GPU.

I used to run ubuntu 11.10 on that system and install drivers from Addtional drivers.

Now gave the desktop to my sister, and installed ubuntu 12.04 from a image created by remastersys.

I removed all unnecessary softwares, drivers after installation. It is now working fine.Unity 3D is running but very slow. So I think I need to install the additional driver.

As I told earlier, it is not connected to Internet. Only thing I can do to download the package from another system and install it there. But I couldn't determine which package needs to be downloaded.

What is the actual benefit that Ubuntu (or Debian derivatives) achieve by disabling root user?

Everywhere I read, it says to prevent unintentional damages for inexperienced users. I want to know what exactly, since sudo can execute all commands (that I know/use).

So in what case root can cause damage whereas sudo can't?

PS: I know how sudo works.

I own an dell xps 15. I guess the following is because I have hybrid graphics system (nvidia optimus).

When I run command to find out lcd brightness path using following command,

ls /sys/class/backlight/*/brightness

I receive the following output

/sys/class/backlight/acpi_video0/brightness
/sys/class/backlight/intel_backlight/brightness

Now if I echo a value say 5 to either of them, LCD brightness changes. Only thing is intel_backlight path brightness is very low compared to acpi_video0.

Is it normal? I want to know what is the difference (if any) and whether for this two different paths gnome fails to save my brightness settings on reboot.

I was following instruction from http://www.remastersys.com/ubuntu.html to install remastersys in my system. On apt-get update always get error that the could not find correct structure of URL.

Any help?

I am running ubuntu 11.10 32bit in my dell xps L502. Working well except for a few problems.

1. Blue tooth always turned on reboot,I would like to turn it off always.

2. Screen brightness is not saved. Every time I reboot, the screen goes back to full brightness.How to save that?

3. And the most important problem is internet speed through wi-fi is really very slow when operating on battery.the card is intel centrino Advanced-N 1030 with integrated bluetooth.

Any help will be appriciated... :)
