As I am not yet even near 60 years old, I don't get the reference. But I am old enough to sense, that I probably won't get much deeper into C programming anymore, than wrapping shell commands into the 'system()' function to make them setuid'able. Thus, I will leave the 'xinput' sources where they are and rather use some spare time to see if I can can get any useful information out of 'gdb'. If I succeed, I promise to report to the list - although I don't own a device with touchpad (which most likely would be the second thing to permanently disable immediately - right after the system sounds, if my OS had those preconfigured).

I've had boot-to-boot persistence of a different setting -- for my wifi device. Ony it wasn't the device with the memory, it was the BIOS. The effect was very similar, though. When I entered an area where wifi was forbidden I turned off my laptop's wifi using my OS's tool for doing so. The next time I turned on my laptop I couldn't turn it on again with that tool. It turned out that my OS had turned off the wifi by changing a BIOS-level setting, and when I turned it on the bios told the OS there was no such device when it tried to turn it on again. Frustrating until I figured out I had to use the BIOS to turn it on again. -- hendrik > > > libre Grüße, > > And don't bring me down Bruce! > > If you don't get the reference, that's OK, you need to be over 60 to > get it. > > SteveT > > Steve Litt > Autumn 2020 featured book: Thriving in Tough Times > http://www.troubleshooters.com/thrive > ___ > Dng mailing list > Dng@lists.dyne.org > https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

Hi Florian, I meant stored in memory by xorg. I have no knowledge one way or another about boot-to-boot persistence of touchpad settings.

I can tell. Like I said, I have no knowledge about boot-to-boot persistence, but if I were just taking wild guesses, I'd guess that the touchpad itself has some non-volatile RAM to store its settings, and the OS, when it boots, reads those settings. Keep in mind I've never noticed boot-to-boot persistence.

The only possibility (which is accessible from within Linux and does not require a "stateful" touchpad) coming to my mind to make such a configuration persistent over a reboot AND across different OSes, might be under '/sys/firmware/efi/' - which would presume a UEFI system.

This is > a programmable multi-gesture touchpad which I guess may have flash memory. > > There has got to be a better way Hallo g4sra, as you replied off-list and I don't know of any better way, I bring the issue back to the list: Perhaps someone has a hint on resetting the device, if you'd reveal its make and model? Another idea out of thin air: Did you remove the CMOS battery - or does the notebook provide a button (or pins) to reset the bios password? libre Grüße, Florian -- ooops...

If this key combo really changed something "in hardware", i assume that a "hard reset" of the notebook(?!) should solve the issue... Usually, this is accomplished by removing all power sources and periphery, and then holding down the power button for 15-20 seconds. The idea is to remove any stored electricity (from ac adapter, battery, capacitors) to clear all non-persistent storage. Your devices miles may vary, the manual should mention it. libre grüße, Florian -- Florian Zieboll Hauptstraße 6a D-68535 Edingen Telefon: +49 6203 925 78 36 Mobil: +49 160 690 15 87 E-Mail: f.zieb...@web.de PGP keyID: 0xEE454979FE441FD6 Chat / xmpp: f.zieb...@xabber.de Chat / matrix: @florian_zieboll:feneas.org WWW: https://www.zwischenspeicher.info [message sent otg] ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
