Well, 810 is amazing- great job devs.
The onboard ATI Radeon HD 3200 works out of the box. I ran through the installation as described here: http://wiki.linuxmce.org/index.php/LinuxMCE-0810_alpha2-
really just installed kubuntu 810, ran aptitude update and aptitude dist-upgrade. After the reboot I activated the only listed ATI drivers and proceeded to install LMCE 810- the latest alpha.
I'm exporting the video to a 52" rear projection Panasonic tv via a DVI port. This tv's manual specifically says that the DVI is not for connecting a tv. I have a refresh rate issue trying to use UI2 with overlay. I think this is because the tv only displays a picture at 65Hz- maybe with a different tv the overlay would work. With UI2 and no overlay the UI is very responsive- like I experienced with 710 and an 8500GT.
I'm in the process of converting over the whole house and will try to update as I experience.
BTW- I'm using the 32bit version, M3A78-EM, 4gb of ram, and a AMD AM2+ 4000 cpu.
I had trouble with a busy box error when trying to install kubuntu with a pata hdd and cd/dvd drive on the same cable- this question was asked in another threat. I didn't play with it at all, in instead connected a sata optical drive and used that to install. Probably coincidence that it worked, but maybe worth noting for anyone else that experiences this- although again, this has been discussed previously.
