My only recent annoyance is that my current video card (Radeon RX570) trips something in the kernel to cause it to take 10 seconds to resume (tried to bisect but the issue popped up in the middle of an unrelated issue that broke it completely, so never resolved). And every once in a while (like maybe every couple of months of daily suspend/resume), the atlantic driver for my 10G NIC craps out. > Certain suspend modes require a suitable power supply, too.

And for the most part, outside of hardware only found in servers (e.g. SAS cards and high-speed NICs), the chips and drivers for notebook and desktop hardware are the same. IIRC Windows 11 defaults to suspending after a relatively brief idle time now (as does Fedora desktop), so that computer vendors can meet "green" power requirements. This means that virtually all normal desktop hardware is expected to fully handle suspend/resume. -- Chris Adams <linux@xxxxxxxxxxx> -- _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
