Ubuntu 12.10 running on VirtualBox

If you run Ubuntu 12.10 without 3D support, desktop is slow but it should work fine without problems, if you want 3D support to get a speedy desktop read below.

Here are the steps I followed, it should also work on win 7 64: Install VirtualBox-4.2.5-82494-OSX.dmg, Oracle_VM_VirtualBox_Extension_Pack-4.2.5-82494.vbox-extpack.In ubuntu "sudo /media/lafa/VBOXADDITIONS_4.2.5_82479/VBoxLinuxAdditions.run" to install guest additions.Enable 3D Acceleration in Vbox Settings rebooted the vm.in Ubuntu execute "ccsm" go to OPENGL and disable everything (sync,texture,framebuffer,vertex, buffer swapping), this makes Compiz work a lot more stable, in VirtualBox.On the host os run "VBoxManage setextradata global GUI/Customizations noStatusBar", to help "Guest display is offset on retina display", until this bug is fixed. I still have a problem when running in windowed mode, and the bug is: In Full Screen mode, the mouse works great, but in my macbook pro 15 reti…

From linux just install android sdk from google.
And then run adb commandlien tool from  SDK_FOLDER/platform/tools/adbunzip OneclickrecoveryV0.4.zipUse the EasyRecoveryV0.4.bat file as a reference, read all comments and execute all adb comnands from top to bottom.

Installing multiple iso on a usb drive with Ubuntu

I'm using Multisystem to install multiple isos on a USB drive.

Download:
http://liveusb.info/multisystem/install-depot-multisystem.sh.tar.bz2

unzip and run:

sudo install-depot-multisystem.sh

This will install all required packages and multisystem. After this just run mutisystem from the Ubuntu menu.

MultiSystem allows you to boot your USB drive using QEMU inside Ubuntu to test that the drive is working before booting it on another machine.

Ubuntu 12.04 on Lenovo Q150 with OCZ vertex 2 SSD and 4Gb of Memory

See my old post about about Lenovo Q150, OCZ vertex 2, 4gb of Memory and Ubuntu 11.04 installed on a SSD and using 4Gb of mem.

For ubuntu 12.04 on the Q150, I used a usbdrive flashed using "Startup Disk Creator" from ubuntu 11.10. to save the SSD from constant writes, I did not create a swap partition. I created only one partition and rely on 4Gb of real memory for all the memory needs.
This build detects all the hardware without problems, I recommend installing the nvidia drivers for better 3D and flash performance.


This new version boots faster and feels faster on the Q150 when compared to ubuntu 11.10.
I recommend the update since the install is a breeze and all hardware is setup without any fuzz. The sound, hdmi video out, wired network, wifi, a Logitech bluetooth keyboard, a usb wireless Logitech mouse, logitech usb sound bar speakers, blue-tooth dongle for the keyboard, all works great. I didn't found time to test hdmi sound out, but it should work since it worked on 1…

Ubuntu 11.10 on Lenovo Q150

New related post Ubuntu 12.04 on Lenovo Q150 with OCZ SSD and 4Gb of Memory.

Jan 22 2012: I updated the post and added instructions to describe the sound settings for HDMI using Ubuntu 11.10. This post instructions should work on 11.10 and 11.04, but I recomend using 11.10.

The Lenovo Q150 comes Atom D510 and the nvidia Ion gfx, 2GB of ram and a 250 GB HD, but mine  is running with a OCZ Vertex 2 disk and 4 Gb of memory to improve the speed.

I decided to install the 64 bit version of Ubuntu. I also installed: ubuntu tweakmirominitube (youtube player, without flash)huludesktopskypechromium
