2011.6 KDE fully updated on Compaq Presario CQ50 using Texstar's touchpad solution #2 seems OK but maybe it's me that notices occasional cursor issues.
Issue 1. "cursor freezes" using touchpad. They are not technically freezes b/c I can see the cursor trying to move and if somone else comes along and uses their finger or if I wet my fingertip the cursor will then respond, but sometimes no matter what we do, cursor is hung in one location until mars-jupiter alignment releases it and continue on our merry way.
I have tried the stock 50-synaptics.conf and touchpad cursor works but no tapping hence Texstar's #2 fix. I have tried both with a stock /etc/X11/xorg.conf and with NO xorg.conf
Issue 2. Not really familiar with all the ins-outs of touchpads but I believe main touchpad area is for moving cursor and the little 1/4" strip on the right is for scrolling. Is this correct? ( I am mainly a desktop user). I believe there is such a thing as two finger scrolling and I guess it means if you "walk" your fingertips in the pad area it will act as though you are scrolling. Problem is, sometimes using ONE finger in the main touchpad area gives me scrolling and I can't do anything, especially when filling out online forms or logins.
Issue 3. Making every effort to be "clean" and not brushing touchpad, but many times when filling out online forms, last text cut and pasted (regardless of when or what app last used) will be inserted into a text field in the middle of typing. It is very annoying. Don't know if this is a klipper problem but I am going to disable Klipper.
No problems using a USB mouse.
Any tweaks greatly appreciated?
