Two issues with 2022 swift 5

Hi,

I bought the latest swift 5 last week and installed Ubuntu 22.04 with Linux kernel 5.17.0-1003-oem. There are two issues so far.

1. System suspend still consumes power significantly. Like the battery is 100% before I go to seep, and in the morning I would find it's only 40%. dmesg and sysfs show suspend should work, but somehow some component (likely CPU) doesn't really sleep and consume power.

2. Camera can't be detected. dmesg shows some config is missing for INT3472.

Please note that these two issues only happen on Ubuntu 22.04 but Windows 11.

I just want to know if anyone else sees the same problems and already has the solution. Or any Acer developer can look into this? I can help debug if necessary as I'm a kernel developer (of ARM platforms though).

Thanks!

Sorry, you have posted to an ACER users forum. We are not ACER employees, customer/technical service representatives or Acer software hardware developers or contractors. With that said, your model's power management is optimized by ACER for the Windows environment, not Linux. We have no influence over this corporate decision. Furthermore, you have chosen to install a bleeding edge ubuntu LTS version and might be better off with a more polished 20.04 version like Mint 20.x at this time. Or if you just gotta have 22.04, wait til Mint 21 is ready in a few months. I'm pretty sure there will be much more about these issues on the Mint forums after release.

Thanks for your comment, Jack. Yes I understand what you said. I'm using the latest Linux kernel, and I believe the problems are due to Linux drivers. I will wait for upstream Linux for the fix if any, and before that I will bear with what I have for now. Thanks again!

Yes, the problems are very likely issues with the kernel drivers. It takes a few months for the Linux developers to get caught up with new chipsets. You will either want to run Windows until Linux is ready for this model or live with the issues until they get it ready.
