Install Apps on Playbook from Linux

Hi, first and most hall my time one a pc is on linux mostly Mint so go back to Windows to install apps or sync music in itunes, this is no longer a good practice, I mean go back and forward. You could do this on a virtual machine, but if you don't have Windows it is not possible from virtual machine. Doing it from a browser Chrome / Firefox on Linux/Mac/Windows to manage yours apps on Playbook that is a good thing since the time we spend in front a pc is browsing.
So George J (jgc@gridbook.org) came with this idea tool that you can do this from a browser thumbs up. From Chrome the install takes a few minutes for full instructions follow http://gridbook.org/pb-app-mgr/ on this page, will give you the instructions based on your browser.
Apps that I have install using the tool/web soundcloud this in not a native app so you have to convert or download one with .bar @ http://apps.goodereader.com/apk-2-bar/, apps that I converted in windows and installed from was Nest, Yatse, Houzz, IMBD, and Unified Remote more or less they all work. Hope this help any of you.

Big Thanks to George J for this great tool.

VirtualBox 4.3.4 VT-x error.

Hi, today when I start Windows in VirtualBox it display this error

Failed to open a session for the virtual machine W7.  VT-x is not available. (VERR_VMX_NO_VMX).  Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

I google this error and found this post on VirtualBox forum that solved the problem.
      https://forums.virtualbox.org/viewtopic.php?f=7&t=58826
But the command on that post is not complete...

VBoxManage modifyvm vmname longmode off

So mine virtual machine is called "W7"...

VBoxManage modifyvm w7 longmode off

 In terminal...

"VBoxManage: error: Could not find a registered machine named 'w7'
VBoxManage: error: Details: code VBOX_E_OBJECT_NOT_FOUND (0x80bb0001), component VirtualBox, interface IVirtualBox, callee nsISupports
VBoxManage: error: Context: "FindMachine(Bstr(a->argv[0]).raw(), machine.asOutParam())" at line 455 of file VBoxManageModifyVM.cpp"

you can see this error is because of the lower case, again in terminal...

VBoxManage modifyvm W7 longmode off

"VBoxManage: error: Invalid parameter 'longmode'"

but if added -- at the beginning of longmode it will work and solve the problem.

VBoxManage modifyvm W7 --longmode off

I hope this help some one.

Get back Boot splash after install of Nvidia Driver.

My boot was a text displaying "Linux Mint 15" with 4 dot's on bottom and Nvidia logo after. I try install custom boot splash's but after reboot the same was displaying. The solution came after many attempts. My graphics Nvidia  Geforce 8400M GT, driver 310.44 linux 64 bit. This as taken from askubuntu.com last post...

First install hwinfo by running the following command:

sudo apt-get install v86d hwinfo

After the installation run the following command and note down the highest resolution:

sudo hwinfo --framebuffer

For me this was Mode 0x0361: 1280x800 (+5120), 24 bits, next edit the following file:

gksu gedit /etc/default/grub

This will open the GRUB config file, we now look for GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and change it with the following, change your resolution with mine and also add the color depth (for me 24 could be 16 or 32).

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x800-24,mtrr=3,scroll=ywrap"

Then find the following line (uncomment if needed) and change your resolution again, note that you don't include the color depth:

GRUB_GFXMODE=1280x800

Save and exit, next edit the following file:

gksu gedit /etc/initramfs-tools/modules

Scroll to the end of the file and add the following line, again add your resolution and the colordepth like you did before:

uvesafb mode_option=1280x800-24 mtrr=3 scroll=ywrap

Then in the terminal type the following commands and then reboot:

echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
sudo update-grub
sudo update-initramfs -u

For me this fixed the problem, I tried all the other suggestions and scripts, none of them worked but this does, good luck!

To remove the Nvidia splash logo add "NoLogo" to xorg.conf, by

sudo gedit /etc/X11/xorg.conf

Section "Device"
     Option "NoLogo" "True"

Then you can install super-boot-manager to managing the boot splash.
My boot splash

Enriki-theme

I hope this help.

Get back login sound in Linux Mint 15

For me this all ways been difficult to get back the login sound, after many attempts I fund this post on "community.linuxmint.com" and I get back my login sound.
          The process is by adding a command to the startup  applications...
Menu/Preferences/Startup Applications
or
Menu/ search...
if you don't have the Gnome Login Sound you have to add this by clicking on Add button.
 In there you have 
                              Name:
                              Command:
                              Comment:

for Name: add  GNOME Login Sound

for Command: add  paplay /usr/share/sounds/LinuxMint/stereo/desktop-login.ogg

for Comment: add  Plays a sound whenever you log in

the Comment field can be blank but the other two are important.

You can test this on terminal by run the Command: above, but this give the opportunity to us to add your own custom login sound, I hope this was help full to you like was to me.
