Cheers Suspending the laptop seemed to work when I was not using X and running GENERIC. I tried again just now, first without unloading, then removing a few kernel modules, but it did not help. If I find time, I'll investigate further. If there is a setting to xorg.conf that does work for setting the screen brightness, please tell me.

Cheers OK, now I feel foolish now: I _had_ tried the RegistryDwords EnableBrightnessControl=1 setting once, but had a typo in it and didn't notice. Now I brightness control also works. So the only remaining problem really is putting the machine to sleep. Should teach me not to accept failure to quickly ;) Best regards, and thanks for the tip. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

At first I thought so too, but apparently you need the right drivers to get some of the keys to work: Now I am finally able to control the brightness by pressing Fn + Home/End, but only thanks to the co-operation of the acpi_video acpi_ibm modules and the nvidia driver (which needs the RegistryDwords EnableBrightnessControl=1 option in xorg.conf). And just to make things more complicated: the keyboard light and mixer mute keys seem to still be hard-wired and thus do not need driver support... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Which Lenovo Laptop?
Hi, so which current 14 Lenovo laptop is the best for FreeBSD compatibility right now? Is it the T420 with the Nvidia card (Nvidia card forced in the BIOS)? Sleep modes work with the T420, right? And I guess Intel Wi-Fi cards are the most supported ones, right?
