Lendo o bug relativo ao driver PSB --
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-psb/+bug/406651 --, encontrei isto:
WORKAROUND FOUND:
On a FRESH install of 2.6.28-11, I installed xserver-xorg-video-psb as documented and rebooted. This gave me the same "Failed to load kernel module "psb." This driver currently needs DRM to operate." errors as mentioned above.
As suggested by hardyrulz, I continued with low-res graphics, then did:
sudo apt-get install psb-kernel-source
sudo shutdown -r now
which TOTALLY worked! Yay! I had 1366x768 on my Aspire 751h!
But... my elation was short-lived. After using Update Manager to update EVERYTHING, I rebooted into 2.6.28-14 and got the same incompatibility errors as before.
pjman suggested a reinstall, which I attempted with:
sudo-apt install --reinstall psb-kernel-source
Which CRASHED my session. So the lesson here is DO NOT SIMPLY "REINSTALL." Don't feel bad, though, pjman. I would have totally tried that without your suggestion anyway. :)
So I rebooted and did:
sudo apt-get remove psb-kernel-source
sudo apt-get install psb-kernel-source
sudo reboot
Awwww, yeah. I'm back at 1366x768, baby!
So it would seem that any time the Jaunty version changes, a "remove" and "install" of psb-kernel-source (and NOT a --reinstall) will do the trick!
Em suma, instale o driver PSB:
1) crie o arquivo de fontes para o PPA:
sudo gedit /etc/apt/sources.list.d/ubuntu-mobile.list
2) inclua as linhas abaixo no arquivo aberto, salve e feche:
deb
http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main
deb-src
http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main
3) instale a chave e o driver:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C6598A30
apt-get update
apt-get install xserver-xorg-video-psb
4) reinicie o computador;
5) recebendo o erro:
failed to load kernel module "psb"
This driver currently needs DRM to operate
siga o "workaround":
5.1) inicie em "low graphics mode" (opção em "sessões" do GDM);
5.2) rode os comandos:
sudo apt-get remove psb-kernel-source
sudo apt-get install psb-kernel-source
sudo reboot
Tudo que eu escrevi presume que seu Ubuntu esteja integralmente atualizado. Se não está, faça todas as atualizações antes com os comandos:
sudo apt-get update
sudo apt-get upgrade
Boa sorte.
