Lenovo T480 sleep/wakeup display problem
by ajevremovic from LinuxQuestions.org on (#4TBKG)
Hi guys,
I'm experiencing a problem with Lenovo T480 laptop with i7 CPU and Intel Corporation UHD Graphics 620. Most of the time the laptop works perfectly well, but the problem is waking it from the sleep (especially, when being connected/disconnected from a docking station).
Sometimes, the laptop wakes from sleep almost immediately, but in the most of the cases display is blank (on, with the back light on, but empty) for some amount of time - usually between 20 and 60 seconds, but in some cases I have to turn it off or reset via REISUB instruction.
The dmesg output is the following:
