First post was incomplete, more informations: Precitations This issue is present shutting the lid of my laptop, which is set to suspend on close and also clicking the word Suspend in the GUI. Shutting the lid of my laptop + power button to resume: black screen. Standby clicking the word Suspend in the GUI + power button to resume: appear the login screen but all is freeze, also the pointer. In both cases I have to power off the laptop with long pressing the power button.
More tests Here there are more logs. Operation that I did before make these logs: - disabled auto suspend after lid close - suspend using Suspend button in the GUI - resuming using the power button (appears freezed login screen) - power off long pressing power button - start and create logs attached in this post cat /proc/acpi/wakeup > wakeup [output in wakeup.txt] sudo su echo freezer > /sys/power/pm_test exit sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" ((nothing happens for more than 30 seconds so I suspend using GUI button, resume using power button (black screen), long press power button to power off, boot the system)) dmesg > dmesg-freezer.txt [output in dmesg-freezer.txt] sudo su echo devices > /sys/power/pm_test exit sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" ((few seconds, then black screen for 2-3 seconds, re-appear the screen when I run the "sudo...pm-suspend" command but all is freezed, long press power button to power off, boot the system)) dmesg > dmesg-devices.txt [output in dmesg-devices.txt] sudo su echo platform > /sys/power/pm_test exit sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" ((SAME SEQUENCE in previous parenthesis)) dmesg > dmesg-platform.txt [output in dmesg-platform.txt] sudo su echo processors > /sys/power/pm_test exit sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" ((SAME SEQUENCE in previous parenthesis)) dmesg > dmesg-processors.txt [output in dmesg-processors.txt] sudo su echo core > /sys/power/pm_test exit sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" ((SAME SEQUENCE in previous parenthesis)) dmesg > dmesg-core.txt [output in dmesg-core.txt] sudo su echo none > /sys/power/pm_test exit sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" ((after some seconds system is suspended, I press power butto to resume, appear the screen when I run the "sudo...pm-suspend" command but all is freezed, long press power button to power off, boot the system)) dmesg > dmesg-none.txt [output in dmesg-none.txt] cat /proc/acpi/wakeup > wakeup [output in wakeup-none.txt] In dsmeg-freeze.txt i found [...] [ 4.130534] Magic number: 12:508:188 [ 4.130595] thermal LNXTHERM:04: hash matches [ 4.130603] acpi device:47: hash matches [ 4.130608] acpi device:1a: hash matches [...] In all other dsmeg-*.txt logs there is this two lines [ 4.******] Magic number: 15:0:0 [ 4.******] memory memory48: hash matches I don't know if my sequence is bad or not, I've try to follow the https://wiki.ubuntu.com/DebuggingKernelSuspend guide but whitout (I'm sorry) modify the RTC clock.
