Ubuntu 11.10 was freezing on Netbook Acer Aspire one 722

Hello guys.

After a long time without post an article, here it goes my first post of this year.

Some days ago I bought a Netbook Acer Aspire one 722 and I have decided to install the Ubuntu 11.10. During the installation or after of the installation it was freezing.

It was going on due Broadcom wireless driver. To solve that, just follow the steps below:
- Restart your computer - Press F2 to start BIOS setup - Select Boot option and in the Boot priority order list, leave "Network Boot : Atheros Boot Agent" in the first place

After that, you can use the netbook without any problem regarding freezing.

That’s it. See you next time.

Happy new year!

Installing Kubuntu 11.04 after installed Ubuntu 11.04

Hello folks.

You already have installed Ubuntu 11.04 but you haven’t liked the Unity. You want to try another window manager like KDE. So you can install Kubuntu, it comes with KDE.

To install Kubuntu, open a terminal and run:
sudo apt-get install kubuntu-desktop

During the installation, you will be asking about which display manager you want to leave as default. Choose kdm.

Now, if you want a full KDE installation that include multimedia, networking, graphics, education, games, system administration tools, and other artwork and utilities, still in the terminal, run:
sudo apt-get install kde-full
After that, restart your computer and in login screen, don`t forget to select KDE.

That’s it. See you next time.

Installing Kernel 2.6.39 in the Ubuntu 11.04 (Natty Narwhal)

buildall — Wed, 01 Jun 2011 15:32:17 +0000

Hello everybody.

The Kernel 2.6.39 was released in May 19th and includes support for ipset and interrupt handling can now be handled almost entirely by kernel threads, the ext4 file system and block layers are now able to scale better and show better performance and the kernel now includes a network backend for Xen virtualisation. A complete list about what has new in the Kernel you can get in www.h-online.com.

Now, it’s time to compile and install the new Kernel. Only to not repeat what was written in Installing Kernel 2.6.38.3 in the Ubuntu 10.10, follow this post to install this one and also don’t forget to change the reference to this one. In other words, instead of use linux-2.6.38.3.tar.bz2 you will must use linux-2.6.39.tar.bz2.

After run the command sudo make menuconfig, If you received the error below:

*** Unable to find the ncurses libraries or the
*** required header files.
*** ‘make menuconfig’ requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2

Still In the shell, type:
sudo apt-get install libncurses5-dev
After that, run the command sudo make menuconfig again.

If you have any doubt about this post, feel free to ask me.

That’s it. See you next time.

How to fix the error “libstdc++.so.6: wrong ELF class: ELFCLASS64″ after installed GCC 4.6

buildall — Mon, 30 May 2011 18:42:39 +0000

Hello folks. If you compiled and installed GCC 4.6 and during the Android Gingerbread (or another software) compilation you received the following error message: “libstdc++.so.6: wrong ELF class: ELFCLASS64″.

Don’t worry about that. You are just using a wrong architecture of the libstdc++.so.6 in the folder /usr/lib32 in Ubuntu 64 bits. To solve that, open a terminal, go to the place where you have built GCC 4.6 and run the commands below:
sudo cp build/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs/libstdc++.so.6.0.16 /usr/lib32 cd /usr/lib32

sudo rm libstdc++.so.6 sudo ln -s libstdc++.so.6.0.16 libstdc++.so.6 sudo ln -s libstdc++.so.6.0.16 libstdc++.so sudo ldconfig
Doing that, we copied the libstdc++.so.6 for 32 bits in /usr/lib32 and also updated the links to this one. Now, all software that need this lib for 32 bits will use this one for compilation.

Remember, the lib libstdc++.so.6.0.16 is the version when I compiled GCC 4.6. If you get the file recently, this version will be different. Just don’t forget to change the reference to this one.

That’s it. See you next time.

How to fix problem of incompatibility between GCC 4.6 and Android 2.3 (Gingerbread)

buildall — Fri, 27 May 2011 12:06:22 +0000

Hello everybody. Let’s see how we can fix one problem that can happen when you try to compile the Android 2.3 after you already have installed GCC 4.6.

During Android compilation you can receive the following error message:
host Executable: acp (out/host/linux-x86/obj/EXECUTABLES/acp_intermediates/acp) host SharedLib: libneo_cs (out/host/linux-x86/obj/lib/libneo_cs.so) host C++: libutils <= frameworks/base/libs/utils/RefBase.cpp frameworks/base/libs/utils/RefBase.cpp: In member function ‘void android::RefBase::weakref_type::trackMe(bool, bool)’: frameworks/base/libs/utils/RefBase.cpp:483:67: error: passing ‘const android::RefBase::weakref_impl’ as ‘this’ argument of ‘void android::RefBase::weakref_impl::trackMe(bool, bool)’ discards qualifiers [-fpermissive] make: *** [out/host/linux-x86/obj/STATIC_LIBRARIES/libutils_intermediates/RefBase.o] Error 1 make: *** Waiting for unfinished jobs....

To fix that, open a terminal and run (assuming you are in the folder android):
gedit frameworks/base/libs/utils/Android.mk
Change the line:
LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)
To:
LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) -fpermissive
After that, save the file and recompile the Android again.

That’s it. See you next time.

How to disable auto login in Ubuntu 11.04

buildall — Wed, 25 May 2011 00:23:51 +0000

Hello folks. You turned on your computer and noted, it did the login automatically. You already enable it through Login Screen Setting but you didn’t have success. To solve that, open a terminal and run:
sudo gedit /etc/gdm/custom.conf
The file contents has something like that:
[daemon] AutomaticLoginEnable=True AutomaticLogin=user
Now, change the value of AutomaticLoginEnable to False. The result will be this:
[daemon] AutomaticLoginEnable=False AutomaticLogin=user
Save the file and restart your computer.

That’s it folks. See you next time.
