Touchpad tapping suddenly disabled for no apparent reason (and a few other things)

On a HP G72 notebook running 11.4. It works perfectlyyyyyyyyyyyyyy

oh, and there’s another bug: it occasionally treats a single keypress as if I’m holding it down. Also, it will sometimes skip a few keypresses in the middle of a word. I found an older solution in the forums, to increase thhhhhhhhhhhhhhhhhhhhhh
the repitition speed to 800, but that hasn’t helped.

But anyway, this touchpad problem is kind of annoying. It works perfectly for a while, the suddenly I can’t tap to click anymore, though all the other functions arrrrrrrrrrrrrrrrrrrrrrrrrr
are ok.

Oh, and the fn keys don’t work.

Is this on KDE or GNOME? Clean install or upgrade from previous/other linux with reuse of /home?

On KDE, check which keyboard is selected in Systemsettings - Input devices, I’m referring to the model.

OpenSUSE 11.4, KDE. Installed alongside Windows 7, and an install of Mint after that.

The keyboard isn’t on the list, this is an HP G72 laptop.

It may seem odd: the video card ?

In cases where I do see keyboard trouble on a laptop, and the keyboard is not in the list, I give one of the same manufacturer a chance. Result should be immediate, so easy to check.

I’m pretty sure that tapping-disabled is the KDE default. You will have to get into the input devices settings and change that.

I am seeing that KDE takes a while to completely start up. When you see it working for a while, then stopping, you are probably seeing it at a stage where it hasn’t yet finished handling all of its startup settings.

For the fn keys: no luck with any of the HP or generic keyboard models. The other two problems are harder to test since they occur so randomly.

Add the following option to the GRUB options at bootup;

acpi_osi="!Windows 2009"

If that helps, can look at a permanent change.

Is that to get the fn keys to work?

It may help in both cases…

I tried adding that line at boot, but “file not found”.

Strange error, it’s not a file… so you added it to the end of the GRUB

Yes, at the grub menu, after some lines that were there already. Or am I supposed to put it in menu.lst?

Anyway, going to try again in case I made a typo.

I typed it at the wrong entry in grub, there’s a “file not found” on a broken Mint installation.

Anywaaaaaaaaaaay,it didn’t work as you can see.

Hmmm, so are the hp kernel modules loading on your system?

lsmod |grep hp

Maybe the hp-wmi isn’t there, which is the “HP laptop WMI hotkeys

I am too facing the same problem. Mine is a HP DV6 pavillion laptop. Suddenly the tapping configuration disappears, But, If i go the kde touchpad configurations and resave my settings, the tapping works again.
