[RESOLVED] Touchpad not working
Well I just installed the Liquorix Kernel through apt like on the webpage and after rebooting (and selecting the default Pop_os kernel in systemd-boot) the kernel was loaded and the touchpad isn't working for some reasons.
OS: Pop_os 20.04 I found the device in multiple commands. under :: Quote :: cat /proc/bus/input/devices:: Code :: I: Bus=0018 Vendor=06cb Product=8254 Version=0100
N: Name="Synaptics TM3336-004" P: Phys=i2c-SYNA2B52:00 S: Sysfs=/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-2/i2c-SYNA2B52:00/0018:06CB:8254.0001/input/input7 U: Uniq= H: Handlers=mouse0 event5 B: PROP=5 B: EV=b B: KEY=e520 10000 0 0 0 0 B: ABS=6f3800001000003 also under :: Quote :: xinput list:: Code :: ⎡ Virtual core pointer id=2 [master pointer (3)]

sudo apt install xserver-xorg-input-libinput sudo apt install xserver-xorg-input-mouse sudo apt install xserver-xorg-input-evdev and under :: Quote :: uname -rI get :: Code :: 5.7.0-8.1-liquorix-amd64Also I don't know how to disable the kernel because in Systemd-boot I only see Pop_os current kernel and oldkernel Back to top |

Hi Gladox114,
I just released an update that should fix your issue (in the next 2 hours pending build times). Last release I merged some HID/DesignWare patches that reduce power consumption under use, but it looks like some touch pads/screens malfunction with these enhancements. Jan reverted the patches in upstream Zen Kernel but I hadn't released an update yet. Fortunately there's some other worthwhile updates this time around so I just spun out a new release. 5.7.0-8.2 should resolve your touchpad issues. Let me know if it doesn't. Back to top |

The following is a random hack and should not be added to any kernel under any circumstance. Check my post later for context on where it came from

Do not post random patches to the forum without any context of where they came from. The one you linked is a hack that was quickly shot down here: bugzilla.kernel.org/show_bug.cgi?id=218003#c33
The correct fix entered 6.5.10, per commit: git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v6.5.10&id=3256ad9bb4ce357a0ff686dd0354d020e8af6bab Also, all kernels aside from the latest are COMPLETELY UNSUPPORTED. I"ll add a blurb to your comment that the patch you posted is dangerous an should not be used under any circumstance. Back to top |
