An update on this. There have been a number of ipu6 driver improvements and the web cam on my Lenovo X1 Gen 11 works some fraction of the time. There *does* seem to be a timing problem with the hardware and/or driver.
https://github.com/intel/ipu6-drivers/issues/187 proposes kernel patches which addresses the issue by adding a delay. Reports suggest that this fixes the problem on Lenovo laptops plagued by this instability. I can confirm that MWE fails for me approx 50% of the time but have not rebuilt a kernel from source with the patches myself. See also: https://lore.kernel.org/linux- usb/20241104085056.652294-1-stanislaw.grus...@linux.intel.com/T/#t Is there any way that to request that these patches get into an Ubuntu Mainline build? ** Bug watch added: github.com/intel/ipu6-drivers/issues #187 https://github.com/intel/ipu6-drivers/issues/187 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2063497 Title: MIPI camera on Lenovo Carbon X1 will not work Status in linux package in Ubuntu: Confirmed Status in linux source package in Noble: Confirmed Bug description: I followed the suggestions here for handling the Intel MIPI camera replacing 22.04 for 24.04: https://wiki.ubuntu.com/Lenovo Perhaps I should have installed 22.04? Anyway, this is a new laptop so I went with the new release. I tried both the generic and oem kernel. Same.
