I have a Sony VAIO netbook with Intel GMA-500 Poulsbo Graphics and I'm trying to boot the latest Ubuntu-12.04 Beta-2 using a bootable USB.
According to this Ubuntu-Wiki, support for Intel GMA-500 Poulsbo graphics is promising in Precise-Beta2 and should work out of the box. Of course the wiki talks about a problem when booting from USB and states that restarting X using: sudo service lightdm restart
will bring a functional graphical desktop, but nothing happens for me!
Any help is highly appreciated.
OK here is the solution for Sony VAIO P netbooks with Intel GMA-500 graphics to boot 12.04-beta2:
Create a live version on a USB disk (you can use Ubuntu's "Startup Disk Creator" for this) with enough persistent space (about 1 GB is more than enough). Boot this live version on another computer and update all xserver and kernel packages. You can do this by either specifying the apropriate packages or if you're unsure, simply run:
sudo apt-get dist-upgrade
After the upgrade finishes, shutdown and remove the USB disk.
Now boot the updated live version on your VAIO-P. You will probably end up with a distorted display. According to this section of the wiki switch to console (press CTRL+ALT+F1) and restart X using the following command:
sudo service lightdm restart
after this you will have a fine display to continue testing 12.04-beta2 or installing it on your VAIO-P :)
