LCD remains dark after resume from suspend to ram (S3). I have FreeBSD 10.0-CURRENT installed permanently to my X121e and am willing to test / investigate at any time. Please advise if there is anything I could provide right now. The affected model is a Lenovo X121e (Model 3045-79G, i3, HD3000). Details: http://www.petermann-it.de/files/freebsd-pr-x121e-acpi/dmesg.txt http://www.petermann-it.de/files/freebsd-pr-x121e-acpi/devinfo.txt http://www.petermann-it.de/files/freebsd-pr-x121e-acpi/mpeterma-lenovo_x121e_i3.asl http://www.petermann-it.de/files/freebsd-pr-x121e-acpi/sysctl_hw_acpi.txt How-To-Repeat: # Supported Sleep states as reported by sysctl root@thinkpad:/usr/home/mpeterma # sysctl -a |grep supported hw.acpi.supported_sleep_state: S3 S4 S5 # S3, hw.acpi.reset_video=0 root@thinkpad:/usr/home/mpeterma # sysctl hw.acpi.reset_video=0 hw.acpi.reset_video: 0 -> 0 root@thinkpad:/usr/home/mpeterma # acpiconf -s 3 Result: System suspends, no video after resume, black screen # S3, hw.acpi.reset_video=1 root@thinkpad:/usr/home/mpeterma # sysctl hw.acpi.reset_video=1 hw.acpi.reset_video: 0 -> 1 root@thinkpad:/usr/home/mpeterma # acpiconf -s 3 Result: system reboots immediately # Adding more debug output In ACPI Debugging guide it is recommended to recompile the ACPI module with additional debug mode. Anyway, when I try so, I get a warning: root@thinkpad:/home/mpeterma # cd /sys/modules/acpi/acpi root@thinkpad:/sys/modules/acpi/acpi # make clean make: "/usr/src/sys/modules/acpi/acpi/Makefile" line 4: "The ACPI module is deprecated, set FORCE_BUILD to force it" root@thinkpad:/sys/modules/acpi/acpi # Is this still the way to go, or doesn't the guide reflect the state of FreeBSD 10?
Today I did one further test. Following the guide [1] I tried: $ sysctl debug.acpi.suspend_bounce=1 $ acpiconf -s 3 I ended up with a blank screen (LCD backlight was on). [1] https://wiki.freebsd.org/SuspendResume
Hello, regarding the issue mentioned in the subject (Lenovo Thinkpad X121e not able to resume after suspend to ram) there is finally some progress. I found this few months old discussion[1] on freebsd-acpi (related to Thinkpad X201): "I had a similar problem. After syncing with FreeBSD 10-CURRENT and compiling a kernel without VESA support, I was able to get graphics to work on resume, but only when running X. " This works for the X121e too! It is now able to suspend and resume properly when running Xorg (with i915kms.ko). I'm really happy :-) There is only a (very minor) problem: after the first resume Xorg graphics seem to slow down. When moving windows on the screen they leave some traces behind and it takes some milliseconds until they are wiped away and replaced with the background image. Kind regards, Matthias [1] http://freebsd.1045724.n5.nabble.com/Resume-failed-after-Suspend-on-Thinkpad-x201i-td5723622.html
