I have acquired a Sharp Mebius laptop with the following specs:
AMD Sempron 2600+
1GB DDR RAM
40GB Hard Disk
64MB shared video (adjustable in the BIOS)
VT3108 K8N800 VIA Unichrome Pro video adapter.
So, when I boot from the live CD, the Ubuntu menu and sliding bar appear as usual, however it is replaced by a blank screen. Shortly after, all disc activity stops and the computer appears to 'lock up'.
