I took my PC home, installed ubuntu again on partition and upgraded from 6.06 to 6.10 then 7.04 and eventually to 7.10. I got what I was hoping for, i.e. device driver to support widescreen of 1,440 x 900 and a nice GUI configuration available to switch between video card driver.
The upgrade took a fair while because there were some 9xx files and 1,xxx files to get for the last 2 upgrades. I intend to use that mostly at home while I use MacBook in the office running parallels.
