Ubuntu SP7 Touchscreen not working

[Imbroglius]

Hi,

i installed Ubuntu 23.10 on my Surface Pro 7 including the Surface Kernel as described here.

Surface-Kernel is booting, but Touchscreen is not working.

Can somebody help? Dmesg ist included in this post.

Just got it....

Had to do like in this workaround:
#654 (comment)

After changing this in /etc/default/grub it works.

Same here.

The Surface 7 touchscreen stopped working after updating from kernel version 6.6.6 to 6.7.9 and from iptsd 1.4 to 2.
The Surface 7+ (note the '+') with the same software is fine.

As linked above, the solution is to disable intel_iommu.

How to:

• Edit /etc/default/grub.
• Add intel_iommu=off to the end of the GRUB_CMDLINE_LINUX_DEFAULT variable, so it looks like something like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=off".
• Save and quit the editor.
• Run sudo update-grub.
• Profit.
