On the Dell XPS 15 9500 the default suspend behavior is s2idle, which is not great for power consumption. Switching it to deep sleep (S3) however leads the system in a state where upon wake up it freezes with a Dell logo and must be force-restarted. These threads describe the issue: https://www.dell.com/community/XPS/Suspend-and-hibernate-issues-on-XPS-15-9500-on-Linux/td-p/7646809 https://www.reddit.com/r/linuxhardware/comments/guhz5f/xps_15_9500_s3_deep_sleep_not_working/ I tried combination of the suggestions from other models, notably disabling sign of life and also tried disabling all of the security features for a test, but to no avail. I think this is something that must be fixed upstream, but maybe there are workarounds that can be implemented at distribution level? Reproducible: Always
You can fix it locally and developers can fix it in the repository, if you have a patch and can name the exact broken package. Please reopen if you have additional information.
