synaptics reset failed
Posted by HWilton on Fri 2 Feb 2007 at 08:04
Yesterday, i've done some troubleshooting ... it seems that the culprit for the whole hibernate episode is the touchpad. On the login window,i pressed ctrl+alt+f1 entering the console in text mode (i thougt reducing the environment to a minimum (no graphic interface) was a good start ! then i forced the sleeping on every 10 seconds
sleepd -u 10Waited and suddenly the lcd went black, and resumed instantly with this message "synaptics reset failed" twice and some details on the driver. [...]

I'm pretty sure the touchpad is not the problem the problem that prevents your system from entering suspend. Yes, there is a problem with the touchpad but that is not very important. (see below for details) My system is a NX7400 and both suspend to disk and suspend to ram work now. I have a page describing what is required to make it work. http://r2d2.stefanm.com/nx7400.html
Some help for your problem:
Suspend 2 disk:
(I get best results with software suspend 2. So I'm only describing this.)
Yes, you need a partition where ssusp2 can store data. However this is your normal swap partition (I hope you have one). Just append the parameter resume2=swap:/dev/hdaX (or sdaX) to your /boot/grub/menu.conf
Suspend 2 ram:
I've had bad experiences calling s2ram directly on HP machines. You better use "hibernate -F /etc/hibernate/ram.conf". If your display stays black after resume use the brightnesskeys to activate it again.
If you like you can also mail me if you like (the address is on the page mentioned above).
P.S.: The touchpad problem is that the touchpad seems to take some seconds after resume. Theoretically this wouldn't matter, but the Xserver tries to reinitalise it, fails, trys to initialize it as a ps2mouse (now the touchpad is ready), suceeds. Now the touchpad's scroll function is gone. I'm currently looking into this problem and found your page that way.

Very good point !
Indeed, this poor synaptics touchpad wasnt the culprit at all - actually, after my troubleshooting session ; i decided to reinstall Debian, and this time installed kde environment (my previous attempt was with xfce) and then it worked fine (i just had to allow the hibernate feature from the klaptop last panel).
But your comment is very valuable to me, and i appreciate it.
thanks

There's still a funny issue, with the battery though the description would be that the battery and AC status stops updating ; which mean the status is accurate just after boot, but wouldnt change during the use of the nx6310. The funny thing is if i remove the battery, and put it back - the problem is solved for the next reboot (battery status is accurate, and updated) - but that only last for this session... That is quite similar to that closed bug : https://bugs.launchpad.net/ubuntu/dapper/+source/linux-source-2.6 .15/+bug/47561 For similar HP laptop.
