Re: ACPI Lenovo X121e (Model 3045-79G, i3, HD3000) Suspend and LCD Brightness
Hello Kevin, Zitat von Kevin Oberman rkober...@gmail.com: Can't help with suspend/resume, but I can point you to the brightness solution. This is probably the same issue that impacts most recent Lenovo laptops. If so, there is a fix in the thread titled Fixing X220 Video The Right Way on this (acpi@) mailing list with the patch by jhb on Feb. 28, but be usre to a followup message on using the fix posted on June 14. It' a tricky issue with getting a string with quoted characters parsed correctly. There have been a number of discussions on ThinkPad suspend/resume, but I have not seen a reliable fix. (I can't resume mine at this time, though it suspends fine :-) Thanks for your reply. I found the thread you recommended to me and followed up with it. Looks like I cannot apply the same procedure unchanged to the X121e. It would be interesting to know if the suspend / brightness issues are specific to the Thinkpads with integrated Intel HD graphics or if also the NVidia models are affected.

ACPI Lenovo X121e (Model 3045-79G, i3, HD3000) Suspend and LCD Brightness
Hello, on a Lenovo X121e (Model 3045-79G, i3, HD3000) I try FreeBSD since 9.1. Wifi, LAN, Audio, USB peripherials and Video (with KMS patch) just working fine. Anyway, there are some open items: * LCD brightness control doesn't work * Suspend to RAM (S3) doesn't restore video after resume That's why I upgraded my system to 10.0-CURRENT and looked in more detail at it: root@thinkpad:/usr/home/mpeterma # uname -a FreeBSD thinkpad.local 10.0-CURRENT FreeBSD 10.0-CURRENT #0 r252853: Sat Jul 6 02:01:48 CEST 2013 root@thinkpad.local:/usr/obj/usr/src/sys/GENERIC amd64 # LCD Brightness First, on LCD brightness: The X121e is expected to increase/decrease LCD brightness by Fn+F9/Fn+F8. This is not working right now. So I tried the following: ## Attempts ### acpi_video / sysctl hw.acpi.video.lcd0.brightness This is what is working on most of the other laptops I tried it. root@thinkpad:/usr/home/mpeterma # kldload acpi_video acpi_video0: ACPI video extension on vgapci0 root@thinkpad:/usr/home/mpeterma # sysctl -a |grep bright hw.acpi.video.lcd0.brightness: 35 root@thinkpad:/usr/home/mpeterma # sysctl hw.acpi.video.lcd0.brightness=100 hw.acpi.video.lcd0.brightness: 35 - 100 Result: LCD brightness doesn't change after sysctl call, Fn+F9/Fn+F8 not working. ### acpi_ibm / sysctl dev.acpi_ibm.0.lcd_brightness This is what worked on some older Thinkpads. root@thinkpad:/usr/home/mpeterma # kldload acpi_ibm acpi_ibm0: IBM ThinkPad ACPI Extras on acpi0 root@thinkpad:/usr/home/mpeterma # sysctl -a | grep bright hw.acpi.video.lcd0.brightness: 90 dev.acpi_ibm.0.lcd_brightness: 7 root@thinkpad:/usr/home/mpeterma # root@thinkpad:/usr/home/mpeterma # sysctl dev.acpi_ibm.0.lcd_brightness=1 dev.acpi_ibm.0.lcd_brightness: 7 - 1 Result: LCD brightness doesn't change after sysctl, Fn+F9/Fn+F8 still not working. ### Activate sysctl dev.acpi_ibm.0.events root@thinkpad:/usr/home/mpeterma # sysctl -a | grep dev.acpi_ibm.0.availmask dev.acpi_ibm.0.availmask: 67733756 root@thinkpad:/usr/home/mpeterma # sysctl dev.acpi_ibm.0.events=1 dev.acpi_ibm.0.events: 0 - 1 root@thinkpad:/usr/home/mpeterma # sysctl dev.acpi_ibm.0.handlerevents='0x03 0x04 0x10 0x11' Result: Fn+F9/Fn+F8 still not working. ### Direct ACPI calls with acpi_call root@thinkpad:/usr/home/mpeterma # cd /usr/ports/sysutils/acpi_call/ root@thinkpad:/usr/ports/sysutils/acpi_call # make install clean root@thinkpad:/usr/ports/sysutils/acpi_call # kldload acpi_call root@thinkpad:/usr/ports/sysutils/acpi_call # acpi_call -p '\VBRU' root@thinkpad:/usr/ports/sysutils/acpi_call # acpi_call -p '\VBRD' Result: on each acpi_call, \VBRU increases and \VBRD decreases LCD brightness by one step. Fn+F9/Fn+F8 still not working. ## Summary Direct ACPI calls are sufficient as workaround. I would like to support a real solution. What are the next steps to find out what is wrong here? I think a solution for this problem will help not just X121e users but any user of more recent thinkpads. I saw similiar postings for X230 and X220. # Suspend to RAM The following observations I made without the i915 KMS module loaded (in console mode). ## Attempts ### 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.
