As the reader of this blok know, I used to proudly ride a bike found within the public garbage (see here). After more than 10000km, it is time to change, because I inehrited a better bike. So now you can see me with this really nice light blue bike, better than the previous one, but hopefully not so good to be stolen.
This detailed guide is taken from http://askubuntu.com/questions/205112/how-do-i-get-amd-intel-hybrid-graphics-drivers-to-work. Thanks a lot for finding the solution.
Let’s install all the required packages
sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6
sudo apt-get install dkms libqtgui4 wget execstack libelfg0 dh-modaliases
sudo apt-get install linux-headers-generic xserver-xorg-core libgcc1
Being VPCSB1V9E a 64bits system, the following steps are also required:
sudo apt-get install ia32-libs lib32gcc1 libc6-i386
cd /usr ; sudo ln -svT lib /usr/lib64
The following deb packages have to be downloaded from the links
Next step consists in the removal of old intel and fglrx drivers
sudo apt-get remove fglrx*
sudo apt-get remove xserver-xorg-video-intel
and the installation of previously downloaded deb files
sudo dpkg -i libudev*
sudo dpkg -i xserver-xorg-video-intel_2.21.6-0ubuntu4_amd64.deb
The xserver driver have to be prevented from any upgrade with the following command
sudo apt-mark hold xserver-xorg-video-intel
Eventually we are ready for the installation of the ATI Catalysts driver (13.4); we have to download the zip file from the official website: www.amd.com/drivers, and then run the executable to build a deb package and to install it
sudo sh ./amd-catalyst-XX.X-linux-x86.x86_64.run --buildpkg Ubuntu/raring
sudo dpkg -i fglrx*.deb
There are at the end few post-installation steps to be executed:
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup (if present)
sudo aticonfig --initial -f
Then, to switch to the discrete (ATI HD6470) gpu, you need to execute the following command
sudo aticonfig --px-dgpu
and then reboot the computer. Once started it again, it should use the ATI gpu. To switch back to the integrated one (INTEL HD3000), run the following command
sudo aticonfig --px-igpu
and reboot again
August in Pavia is not that exciting, because of weather and mosquitos. However today it was a nice sunny day and, in the afternoon, we decided to go to Campus Acquae swimming pool. For Lorenzo it was the first time in an open swimming pool, and it was really excited. I think we will come back before the summer will end
We met them in Grenoble roughly two months ago (see here), and in a while, they are ready to fly to California, for a new job and life experience. Marco, Anna and Matteo travel a lot, but for sure they are true friends to us. And we enjoyed the dinner tonitght, with a simple pizza and an home made “gelato”, but also with their warm friendship. Thanks for coming, and see you soon, probably in USA.
This summer we were not able to organize the vacations as expected because there was some trouble we had to face on. However, to escape from the hot Pavia, at the end we were able to stay few days at Schilpario, a little village on the Alpes. It was high enough to be breezy, at least during the night, and we enjoyed the presence of all the grandparents. Here you can see few pictures, to remember a vacation that, for many reasons, was really speacial.
