Having made several attempts to install Ubuntu 10.04 in a Packard Bell Notebook PC with NVIDIA 128MB Graphics Card, 30GB hard drive, 1GB memory, 3.6GHz Intel Pentium 4 Processor, I failed to get it working. I have installed and used all other Ubuntu releases in the past without any problems. I have now gone back to Ubuntu 9.10, which works very well in the same Notebook PC. Ubuntu 9.10 boots up in approx. 20 secs and is an extremely stable version of Ubuntu I have used up to now. My view of Ubuntu 10.04 is that it requires a lot more participants to install and see how good and stable it is in their PCs. I have written to Ubuntu community and received many comments about the issues I had during the installation process and none of the comments helped me to resolve the problem.
