There is no 3D hardware acceleration for SiS GPU's. Unity is just not going to run fast...

Both machines seems to have the same capabilities. BUT : 1- NO wifi detected on the ACER. (OK on the Dell) My first installation hang on kernel configuration for the wifi driver. I found on a blog that un-checking the "use proprietary modules" solved the problem and allowed the installation 2- Machine completely unresponsive with Unity (3D accelerator seems absent) but completely functional with Xubuntu desktop) (Surprisingly smooth on the Dell) 3- NEVER power off when "shutdown" or "reboot" is requested. Every thing seems stopped. but the machine remains powered and the "shutdown screens" continue to run with its animation I think that this is caused by missing specific/proprietary drivers, BUT when I check for "proprietary drivers" none are proposed....
