Melanjutkan pemecahan pada Dell XPS 13 9350 saya setelah saya memutakhirkan dari 16,04 LTS ke 17,10. Ketika saya akan menutup tutupnya, sejauh yang saya tahu, sistem ditangguhkan (meskipun saya kira itu mungkin jatuh pada saat itu). Saya melihat entri seperti ini di / var / log / syslog:
Nov 22 21:42:01 foxy systemd[1]: Starting TLP suspend/resume...
Nov 22 21:42:02 foxy systemd[1]: Started TLP suspend/resume.

Pesan-pesan itu sendiri tidak benar-benar menunjukkan sesuatu yang tidak biasa (setidaknya untuk sistem saya - saya ingin tahu apa artinya kesalahan). Ketika saya membuka tutupnya, saya akan melihat POST BIOS dan sistem akan boot. Ini tercermin dalam log, yang memiliki pesan seperti ini segera mengikuti potongan di atas:

Lanjutkan mulai berfungsi dengan benar setelah saya menginstal paket "uswsusp":
sudo apt-get install uswsusp
Ini adalah solusi yang dijelaskan di sini: XPS 13 9350 (2016) menangguhkan - masalah suara
Sekarang, ketika saya menangguhkan, saya melihat lebih banyak entri syslog yang menunjukkan sistem dengan benar masuk ke status ditangguhkan:

Lagi pula, saya tidak tahu mengapa paket "uswsusp" hilang atau sepenuhnya mengapa itu memperbaiki masalah. Sepertinya itu harus menjadi paket yang diperlukan.
