Thanks for your info.
There were xorg packages updated during the upgrade. The first time I
upgrade only the linux-image, the X can not be started up due to my NV
display driver issue, so that I used dist-upgrade.

Although the aptitude issue and the display drivers are resolved and
working fine, I found the system is behaving a little slower than
before. It's quite obvious to see that the output is returned slowly
when I execute the "df -h" to check the disk info. That's why I'm
thinking about the downgrading....

Per your suggestions, I think I need to keep it as updated and change
the source list to testing, waiting to see if there is any improvment in
future!

Thanks a lot!
Michael
