1440×900 Ubuntu on Aspire One 751
I’ve upgraded my Ubuntu install from 9.04 to 9.10, even though version 10.04 seems to be on the way. After the upgrade though, it seemed my preferred resolution of 1440×900 wasn’t available any longer. As the title states, I have an Acer Aspire One 751 which I’ve been using for quite a while and am quite happy about. Before the upgrade, I installed some drivers to accommodate the 1440×900 resolution, but I couldn’t remember which one. I fixed it, eventually.
The Acer Aspire One 751 packs an integrated Intel GMA 500 video card, and it appeared it needs the Poulsbo driver to operate decently. On the Ubuntu Wiki, I found a page describing how to install it for Ubuntu 10.04. To make this blog post a bit more complete, here’s what I did: first of all, open a Terminal screen if you didn’t have one open already. Type (or copy and paste) the following:
wget http://dl.dropbox.com/u/1338581/Gma500/scripts/poulsbo.sh \
&& sh ./poulsbo.sh
After that I rebooted the netbook and chose a recovery shell, which gave me a few options to choose from. I then picked to boot dpkg, which eventually led me to a shell. The only command I issued were the following:
sudo dpkg-reconfigure psb-kernel-source && reboot
Type in your password, let the netbook rattle and hum a little and by the time it rebooted, you should be seeing the Ubuntu login screen with 1440×900. It did in my case anyway
