It's been a few weeks now that PCLinuxOS 2010.1 has been available. I have it installed on my 'old' laptop - a HP Compaq nx6325 - and this is my experience up to now.
So, in went the CD and a few seconds later, the new PCLinuxOS boot screen came up, only to drop to a black screen after a few seconds. Gosh... this is odd. The download was fine, the checksum OK, burned at the lowest possible speed. I went to my desktop, popped the CD in and there everything was OK.
Back to the laptop. Try number 2. Again the same black frozen screen. Even after waiting several minutes, nothing moved. This was really a first. Never since I hopped over to PCLinuxOS (2007 TR1) had I encountered any problems of this kind on the laptop.
