Ubuntu running in low graphics mode following kernel update
I had gotten the optimal 1366x768 resolution working on the Dell Mini 10 with the optional HD display (Poulsbo chipset / Intel GMA500 video) by using the drivers provided by the Ubuntu Mobile Team.1
It's been working great for over a month until this morning, when instead of a login screen, I was greeted with an error: "Ubuntu running in low graphics mode".
What's up with that? The APT log contained the explanation:
* Running DKMS auto installation service for kernel 2.6.28-16-generic * psb-kernel-source (4.41.1)... psb-kernel-source (4.41.1): AUTOINSTALL not set in its dkms.conf.
I guess I could set AUTOINSTALL for the psb-kernel-source module to "Yes". I'll think about it, meanwhile, a manual fix is easy enough:
sudo dpkg-reconfigure psb-kernel-source sudo shutdown -r now
POW. Back in business.
1 By the way, all I had to do to get full resolution working in the first place, as I recall, was add the Ubuntu Mobile Team sources to my /etc/apt/sources.list:
deb http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main deb-src http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main
Install the drivers and reboot:
1 2 3
sudo aptitude update sudo aptitude install psb-kernel-headers psb-kernel-source xserver-xorg-video-psb sudo shutdown -r now
