19.09+5 is available
551568faddbe26f29cdc7cd906006541 LxPupSc-19.09+5-uefi-T-k64.iso

see posts #1 and #2

Quite a significant change to resolve some touchpad problems (with thanks to @Marv for testing assistance).

xf86-input-evdev, xf86-input-synaptics are removed from build....

Real flSynclient is no longer in build.... if you have problems with touchpad settings then guidance is:

Use libinput list-devices to show the configuration options for local devices.
The following web pages provide guidance on configuration:
https://wayland.freedesktop.org/libinpu ... igure_xorg
https://wayland.freedesktop.org/libinpu ... ation.html
https://www.mankier.com/4/libinput

An example:
Create /etc/X11/xorg.conf.d/60-libinput.conf with contents:
Section "InputClass"
Identifier "MyTouchpad"
MatchIsTouchpad "on"
Driver "libinput"
Option "Tapping" "off"
Option "DisableWhileTyping" "true"
Option "HorizontalScrolling" "true"
Option "ScrollMethod" "edge"
EndSection

If you are looking for a GUI touchpad control app based on libinput, see here. It might be compatible with Slackware.

Back in the saddle again with suspends working

19.09+5 generated using the delta, md5sum correct. Tested both with the defaults and just as a test with my custom 60-libinput.conf added into the /etc/X11/xorg.conf.d directory. As expected, the 60 has precedence over the 99. All touchpad mappings and suspend/resume working in both cases. Defaults are really quite good on this i5 based laptop with a synaptics touchpad. I'll probably run with them.

Thanks,

Installed from the deb and quickly tested in LxPupSc 19.09 +5 on a laptop with a SynPS/2 Synaptics TouchPad. GUI comes up fine and tapping on/off and touchpad speed both are set correctly.

Thanks,

Code: Select all

Option "DisableWhileTyping" "true"
Option "HorizontalScrolling" "true"

Those two items are missing from TouchPad. I can make an update that includes them.

As a certified dinosaur I have used

Code: Select all

Option "ScrollMethod" "edge"

though I'm ok with 2 finger scrolling of late so long as I can disable tap.

Here is a Puppy version of Touchpad.

Some of the options are ON by default., depending on the touchpad.

For example, turning on tapping should automatically get you clickfinger and two-finger scrolling.

I have NOT tested this on a Puppy with a touchpad. Other people will need to do the detailed testing.

Note: This is ONLY for Puppies that are using libinput instead of evdev.

There were reports of conflicts between libinput and lxinput. The Mouse section of Touchpad replaces most of the lxinput functionality.

touchpad_puppy-1.9.pet installed to LxPupSc 19.09 +5. I enabled and disabled tapping, switched the ScrollMethod and set several speeds. All worked on this 2nd generation i5 based Fujitsu S761 laptop. I appreciate the view capability you have in your programs. It's really nice to be able to quickly go to the relevant directory and look at the config files the GUI creates.

Thanks,

Thanks for testing.

I'm not sure if the DisableWhileTyping option is even necessary. If the touchpad supports it, it will be on by default.

Otherwise, people can use the Touchpad control > Off button.

@Marv: Puppy has a simpler way to restart X. I have posted a new version above.

Got it. 1.9 uninstalled, 1.9.1 installed and run through its paces. Looks good.

The one thing I do miss from the synaptics drivers' bewildering array of options on this machine is the ability to set the touchpad pressure as on this hardware the pad is quite a bit too sensitive, particularly when using two finger scrolling. Presently not an option with libinput and the pretty clearly won't be added to it.

Thanks,

I'm guessing that it would be impossible to support that kind of option across all the non-synaptic touchpads, so they didn't try.

[Edit] I did find something called "quirks" that lets you fine-tune a touchpad.

[Edit-edit] Read here. Apparently, some Synaptics touchpads have a "fingers" option that you can set.

But none of mine had it. Maybe because the libinput driver doesn't recognize it.

@Marv: I have posted a new version with a Props button.

It shows you the available touchpad properties, their current status and their default status.

This removes some guesswork over what options you need to select.

For example, turning on tapping should automatically get you clickfinger and two-finger scrolling.

@peebee: kernel 5.3.7-lxpup64 swapped into LxPupSc 19.09 +5. All system checks and mem/ssd throughput look good. 1% CPU and 164 Mb reported by lxtask at idle. Early loading of microcode is sucessful and mitigation is

Code: Select all

l1tf:Mitigation: PTE Inversion
mds:Mitigation: Clear CPU buffers; SMT vulnerable
meltdown:Mitigation: PTI
spec_store_bypass:Mitigation: Speculative Store Bypass disabled via prctl and seccomp
swapgs barriers and __user pointer sanitization
spectre_v2:Mitigation: Full generic retpoline, IBPB: conditional, IBRS_FW, STIBP: conditional, RSB filling

Video FPS also good. I'll use it as the daily under the current LxPupSc

@rcrsn51: version 1.9.2 of touchpad-puppy looks great. Probably should have its' own thread. I see it as a viable flsynclient replacement in newer pups since the the synaptics driver pretty much isn't the default there any more. On the touchpad sensitivity issue, AccelProfile doesn't show in the props for my touchpad but I have experimented with flat and adaptive modes and my touchpad does settle better at the end of a move with the flat mode. Currently using

Code: Select all

#    Option "AccelProfile" "adaptive"
      Option "AccelProfile" "flat"  
      Option "AccelSpeed" "0.10"

Cheers,

Option "AccelSpeed" "0.10"

Excellent! So you can just set a touchpad speed, then add the "flat" option to 41-libinput.conf?

That is how I did it but I then rooted around in the Archwiki entry pertaining to libinput and touchpad acceleration control and did some careful tests on my pad. In libinput world, pads that support "AccelProfile" should just force a speed of 0.0 for "flat" while "adaptive" just uses a different touchpad to screen mapping to get the speed. Not true acceleration as we were used to in the synaptics driver at all but more just a different overall mapping factor. So after a second look the AccelProfile seems redundant. As I see it right now, speed does all that the libinput driver is capable of. Leave 1.9.2 as is. With the supported props listed and the view capability it is very simple and fast to add a supported option not in the GUI list. Learning as I go coming from synapticsworld.

Thanks. I set up a mouse with the "flat" profile and I really couldn't see any difference.

It actually listed Acceleration Profiles in its properties.

Many thanks @rcrsn51

Do you think it should be renamed? It has much wider applicability than just touchpad and as you say is libinput specific.

The screen rotation facilities are potentially dangerous as they can lead to formats that cannot be reversed out of. Perhaps they should have a confirmatory "Are you sure you want to do this" dialog before activating the change?

Attached is a mod to make the SCT frame dependent on the availability of sct in the build for your consideration.

Cheers
