@arges I am also experiencing suspend issues on my XPS13 but before opening a separate bug report I would like to check if our systems are affected by the same bug.
Please check/confirm the following: 1. Is your system fails to resume or stuck during suspend? Please suspend the system using system menu (instead of closing the LID) and describe power-button light behavior. Is it turned off after 5-10 seconds? 2. Is there an external monitor? What happens if it's disconnected? (In my case connecting/reconnecting the monitor after the system is booted triggers the issues). 3. Is it a persistent behavior? 4. Is http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.10-xenial/ still broken? (It solved the problem on my system). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1581249 Title: resume on dell xps 15 9550 fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1581249/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
