I am running Qubes on my ThinkPad E495 and most things work pretty well now, after some initial startup problems. I upgraded to kernel-latest and this removed some graphics issues (e.g., not being able to adjust screen brightness). Overall, the system also feels more responsive.
However, I cannot get my laptop to wake up from suspend. I tried different stuff:
- Made sure the UEFI is up to date
- Tried suspending when ALL domUs were stopped
- Disabled the redshift-gtk service that I had installed because I thought it might potentially interfere with something
- I also successfully suspended the laptop using a live USB installation of Kali Linux which I had lying around. This works perfectly and the kernel is way older than kernel-latest on Qubes.
When going into suspend from Qubes, everything looks good (device LED is blinking as it should). When I try to wake the device up, the LED starts to shine permanently, indicating some reaction. After a few seconds, the fans spin up but that’s it. The screen remains pitch black.
journalctl indicates that Qubes never really comes back from sleep. The last message before suspend is “kernel: PM: suspend entry (deep)” and then the log continues after the reboot.
I am not really experienced with troubleshooting such issues. It would be great if anyone could provide help
