Hello dear community, I am new to Qubes OS, and am happy to join your community! I love the qubes concept, and am excited to get it to work.
I’ve read a lot of Forum posts on the topic of Touchpads not working. I have tried all that I could, including adding ioapic_ack=new to GRUB_CMDLINE_XEN_DEFAULT. I even ran into this issue, with sys-usb deleting itself, where I just decided to cut my losses and do yet another fresh Qubes OS install.
On my Lenovo T14s Gen2, on a freshly formatted SSD, and installing Qubes OS 4.3 from USB:
- Touchpad works on all initial install screens
- Touchpad works on the first boot, post-decryption
- Touchpad works while setting up the Templates Configuration (I set everything to the default values)
- After clicking “Finish Configuration”, and while the installation is in progress, the touchpad stops working at the “Installing TemplateVM debian-13-xfce” step (I was monitoring the installation and continuously moving the pointer with the touchpad)
After that, the touchpad does not work anymore, and I must plug in a mouse to click around and update my qubes or create this post. The TrackPoint always works, but I am unable to use it to click because the buttons are connected to the Touchpad.
It doesn’t seem like hardware troubles, since my Touchpad works before the initial configuration on first boot and when booting into GParted via USB (based on Debian live).
What could be my issue here?
Some technical details
I find four devices in the dom0 Mouse and Touchpad settings:
- SYNA800E:00 06CB:CE67 Touchpad
- SYNA800E:00 06CB:CE67 Mouse
- TPPS/2 Elan TrackPoint
- sys-usb: the USB mouse I plugged in
With cat /proc/bus/input/devices on a dom0 terminal, I also see these four devices. For the relevant ones (Touchpad/Mouse and TrackPoint):
