Re: Thinkpad x230 display brightness
Hello, Zitat von bezobraz...@hushmail.com: hi everyone i have a x230 and i have problem with acpi i read and install # cd /usr/ports/sysutils/acpi_call && make install clean # kldload acpi_ibm # kldload acpi_call # acpi_call -p 'VBRC' -i N where N is 0-16. (strangely, 15 is brighter than 16). my output for [ acpi_call -p 'VBRC' -i N ] is "0" but i can change the brighter . can anyone help me ?? i can't find a command-line for change in the terminal or the key FnF8 or FnF9 thz with my X121e I had some success with: 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' while VBRU increases and VBRD decreases by one step brightness of the screen.

Re: Reduced screen light after power disappearing.
Hello, Zitat von Гуляев Гоша : Good day! I have a laptop with FreeBSD 10-BETA4 AMD64. When the power is lost it automatically reduces screen brightness. But when the power comes back, the brightness does not return to a normal level. Fn + BrightUP key do not help. I have no other auto power saving set up except powerd_enable="yes" in /etc/rc.conf The only way to return brightness to a normal level now is to reboot. How I can fix that? You could try to kldload acpi_video. # kldload acpi_video # sysctl -a | grep brightness should show up a key which you can use to set the brightness. # sysctl hw.acpi.video.lcd0.brightness=100 For some vendors (e.g. Lenovo) there are custom modules with their own brightness setting keys: # kldload acpi_ibm # sysctl -a | grep brightness If none of this are working, you might want to try out ports/sysutils/acpi_call and directly calling an ACPI method to increase or set the brightness. This was btw the only way it is working for my Lenovo X121e and E330.

Re: suspend/resume on Lenovo X1 (regression from reports on wiki)
Hi Laura, Am 27.08.2013 22:32, schrieb Laura Marie Feeney: I tried suspend/resume (less systematically) with 9.1-RELEASE and didn't have success. I can build minimal kernels for both 9.1 and 9.0 and will report (probably not tonight). Unfortunately, the SuspendResume wiki isn't completely clear about what build was used - perhaps the folks who reported will be able to clarify. Can you rebuild your kernel without "options VESA". This helped to fix suspend/resume for my Thinkpad X121e.

amd64/181358: Suspend to RAM not working correctly on Lenovo X121e (ACPI issue?)
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.
