I installed the latest PCLOS without a hitch on my desktop, so I decided to give it a go on my aging Dell D600 laptop. I am running into a few issues. As first installed, then updated to all the latest, PCLOS was so slow on this laptop that it was almost unusable, especially with firefox. I figured that this had to be an issue with configuration, since this laptop has run other KDE 4 distros without a problem.
The first thing I did was to try these changes to X-orghttp://www.pclinuxos.com/forum/index.php/topic,78356.msg647259.html#msg647259
That worked OK, but then I noticed some really undesirable mouse behavior. specifically, I would have to hold the mouse over an icon or radio button for a very long time before clicking a mouse button would have any effect. I am using the onboard pointing stick. I tried loading the synaptics touchpad package from the repos, which worked to disable the touchpad (an annoyance solved!) and I ended up changing the mouse settings to disable the feature where the mouse cursor changes shape over an icon. that helped a lot, but didn't solve the problem.
Interestingly, if I plug in a plain old usb optical mouse, everything works perfectly. So the problem is limited to the onboard pointing stick and buttons. I am sure there are a few minor tweaks to configuration or the Xorg that will fix my issue, but I can't put my finger on them at the moment. What am I missing? Thanks.
