Lenovo ThinkPad T480

Thank you @renehoj for your report, which is online now!

I have moved our posts into this thread. So you are using the i5-8250U like @SoPunny.

I think we are close if we can clarify whether there are suspend issues or not. What’s the difference between “Deep Suspend” and “Idle Suspend”? Has anything changed in the last few weeks – @SoPunny?

I’ve spent most of the evening testing the suspend function, and I can’t reproduce the situation where it takes a long time to wake up.

Reconfiguring the thunderbolt port can result in pci devices being added/removed, which means you manually need to update the sys-usb device list.

Enabling hyper-threading adds a 5-10 sec delay on waking up the system, but it doesn’t add the really long delay. This seems similar to how suspend works on my Windows system.

With sys-usb/thunderbolt correctly configured and hyper-threading disabled, it takes ~2 sec to wake up the system.

Sadly, I didn’t check the logs when I experienced the slow wake-up, I think some software/OS error happened during the wake-up, and the long delay is a software timeout.

Tomorrow I’ll try and get a dock and see if using the thunderbolt port makes suspend fail.

For the community recommended list it is critical that a PC works “out of the box” using just the installer and no other instructions or workarounds. Would you say that’s the case with your T480?

I haven’t found any bios settings that prevent you from using Qubes, but I need a dock to test if the thunderbolt port actually works, hopefully I can do this today.

I tried reinstalling Qubes with a couple different Thunderbolt settings, and they all worked “out of the box” with sys-usb being created during installation.

If after installing Qubes you go into the bios and change the thunderbolt configuration, it reconfigures the pci devices and this can result in an unknown or missing device in the sys-usb device list. I assume this is considered outside the standard installation.

The dock worked with default settings, I have not been able to find anything that doesn’t work out of the box.

That’s great! … @SoPunny can you confirm?

Upgraded my motherboard from the i5-8250U to the i7-8650U

The only difference I’ve found is that the i7 is vPro with AMT, apart from that the i5 and i7 are identical.

Everything works.

Thank you @renehoj for your updated report, which is online now!

@aronowski can you confirm that the i7-8650U works out-of-the-box?


As I said earlier, everything seems to work fine and I only get visual glitches by having my cursor at certain height.
Maybe there’s something more precise I could test out. Tell me more if that’s the case.

I do, however, see an older entry:

I haven’t tested Bluetooth

It does work - check this out.
