 |
|
Hi, im having a little trouble with my syneptic drivers.
I read the wiki about [synaptics](https://wiki.gentoo.org/wiki/Synaptics) and followed all steps.
My /etc/portage/make.conf has synaptics and libinput as INPUT_DEVICES and copy pasted the input section from the wiki into /etc/X11/xorg.conf.d/50-synaptics.conf
When I try synclient -l tho it gives me the output:
| Code: | | Couldn't find synaptics properties. No synaptics driver loaded? |
Meaning the issue is in the drivers.
My question: Do I have to compile another kernel and especially select a option for touchpad in my config or is it possible the module is there, but is somehow not getting loaded. I am using the genkernel, so it should work. |

An Ideapad is a modern notebook and uses I2C for its touchpad. We had many problems with this, because not all needed kernel modules are in genkernel.
So, please 1. forget the wiki article (it is for "old" synaptics) and 2. configure your kernel with all needed modules. I made a german guide for this; forget my german language (or use google translate) and use (ALL) the kernel settings: https://forums.gentoo.org/viewtopic-p-8692426.html#8692426 OR search in our forum for one of the many threads about this. Using "libinput" is correct; delete 50-synaptics.conf. |

I searched in the forum, and thats why I specified my device model. The ones I found were very specific fixes, but I will check it out! |

about the I2C
In the I2C wiki it says to run lspci | grep -i smbus.
My output is
| Code: | 00:14.0 SMBus: Advanced Micro Devices, Inc. [AMD] FCH SMBus Controller (rev 61)
|
Does that change anything? |

I think you need
(but I am not sure; maybe try the other AMD after) |
