Lenovo Ideapad Slim 3 15IAH8 touchpad feels sluggish.
by ArchPrincess from LinuxQuestions.org on (#6NWB3)
Hey everyone,
I'm new to the forums and really need help after struggling with this issue for two weeks. I'm experiencing input lag and sluggish movement on my touchpad compared to its precise and crisp performance on Windows. The issue occurs after using the touchpad for 30-60 seconds, often after opening applications like Firefox.
System Information
I'm using Gnome,

- Tested Multiple Linux Distros: Tried various distributions (Ubuntu, Fedora, Debian) before settling on Arch Linux.
- Switched Display Servers: Tested both Wayland and X11 to rule out display server issues.
- Checked for Available Drivers: Unable to find specific drivers for my laptop model.
- Configurations: Created and modified configuration files for both libinput and synaptics drivers (specifically, I tried adjusting sensitivity, acceleration profiles, and tap-to-click settings).
- Disabled Power Management: Modified udev rules to disable power management for the touchpad.
- Kernel Parameters: Added i8042.nomux=1 i8042.reset to improve touchpad performance.
- Monitored System Logs: Noticed kernel message related to touchpad issues but couldn't find definitive solutions (kernel msg: event7 - ELAN06FA:00 04F3:32B9 Touchpad: kernel bug: Touch jump detected and discarded.).
The touchpad sometimes works perfectly after closing and reopening the laptop lid / rebooting the machine and even if I leave the touchpad for a bit it works for a couple of seconds but reverts to its sluggish state after a few seconds or after opening certain applications sometimes.
The touchpad works perfectly on Windows with no input lag or sluggish movements.
The issue seems to be related to software/driver/configuration settings rather than hardware.
It's important to note I have reversed any changes I made back to the original state before I tried to mess with any settings.
I'm seeking further advice or solutions from the community to address the touchpad input lag and achieve the same performance as on Windows. Any insights or additional troubleshooting steps would be greatly appreciated.
Update:
I tried tinkering with more power management options with no success

- Modified the GRUB configuration to disable CPU power-saving states:
Code: sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="\(.*\)"/GRUB_CMDLINE_LINUX_DEFAULT="\1 intel_idle.max_cstate=1 processor.max_cstate=1"/' /etc/default/grub
sudo grub-mkconfig -o /boot/grub/grub.cfg2. Disable USB Autosuspend:

Code: sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="\(.*\)"/GRUB_CMDLINE_LINUX_DEFAULT="\1 usbcore.autosuspend=-1"/' /etc/default/grub
sudo grub-mkconfig -o /boot/grub/grub.cfg3. Disable ASPM (Active State Power Management):

sudo grub-mkconfig -o /boot/grub/grub.cfg4. Disable SATA Link Power Management:
- Added kernel parameter to disable SATA link power management:
Code: sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="\(.*\)"/GRUB_CMDLINE_LINUX_DEFAULT="\1 libata.force=1.5Gbps,noncq"/' /etc/default/grub
sudo grub-mkconfig -o /boot/grub/grub.cfg5. Disable Intel P-State and Turbo Boost:
- Added kernel parameter to disable Intel P-State and Turbo Boost:
Code: sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="\(.*\)"/GRUB_CMDLINE_LINUX_DEFAULT="\1 intel_pstate=disable intel_idle.max_cstate=0"/' /etc/default/grub
sudo grub-mkconfig -o /boot/grub/grub.cfgNetworkManager Power Saving:
- Disabled Wi-Fi power saving:
Code: echo -e "[connection]\nwifi.powersave = 2" | sudo tee /etc/NetworkManager/conf.d/disable-power-management.confBluetooth Power Saving:
- Disabled Bluetooth power saving features:
Code: echo -e "[General]\nDisablePlugins = pnat" | sudo tee /etc/bluetooth/main.confEthernet Power Saving:
- Disabled Wake-on-LAN (WOL) and other power-saving features for Ethernet interfaces:
Code: echo 'ACTION=="add", SUBSYSTEM=="net", KERNEL=="enp*", RUN+="/usr/bin/ethtool -s $name wol d"' | sudo tee /etc/udev/rules.d/10-network.rulessystemd Sleep Configuration:
- Disabled systemd sleep actions:
Code: echo -e "# Empty file to disable systemd sleep actions\n" | sudo tee /etc/systemd/sleep.confScreen Blanking:
- Disabled screen blanking:
Code: xset s off
Update:
After reverting the changes, I noticed something rather interesting. It seems that when my screen goes dim (before entering sleep mode) and I use the touchpad, it works fine for a couple of seconds and then returns to its original state. Note that this happens only sometimes, not all the time. This leads me to the conclusion it probably is a power issue. I'm going to install any firmware I can find for my laptop again, try reverting versions, and come back to update here.
