I have a Acer Aspire One ZA3 (AO751h) and as soon as Ubuntu 10.04 was released I created a USB stick and installed it. Well the truth is that it doesn't work on GMA500/Poulsbo based Netbooks. So as quick as it was installed it was taken off and I tried Mandriva. I was amazed that from boot up off the USB stick that Mandriva detected and used the GMA500 from the word go, but after a couple of hours of using it, I began to miss Ubuntu, so I put 9.10 back onto my machine.
So, what have Mandriva done different to Canonical? Another thing I did was to ask Intel if they were bringing a new driver out for the GMA500 chipset, and I had a sarcastic remark and a comment which went "Your Distro (Canonical) are to blame for this problem, get in touch with them!", so I went onto the #ubuntu IRC and asked when we were going to have GMA500 support in 10.04.
I had the reply, "Intel are to blame for the driver!", in which I replied "How come Intel are blaming you guys, and how come Mandriva works out of the box with this chipset running the latest Xorg?" They were shocked about both!!
So I along with other Ubuntu users who own Poulsbo based Netbooks are stuck with 9.10 till April 2011, and then if there's no support for our devices, we're either forced to install Windows (NOT A CHANCE!!) or throw our machines in the bin!
So if there's anyone from Canonical reading these forums, please sort this problem out!
