Hi Joey,
the backlight works fine, with Fn key or with /sys/class... . But with every change of the backlight, there are 6-9 "*ERROR* fixme: max PWM is zero" entries in /var/log/messages.
It's a warning for BIOS setup max PWM register to 0, it causes by BIOS problem: drivers/gpu/drm/i915/intel_panel.c max = i915_read_blc_pwm_ctl(dev_priv); if (max == 0) { /* XXX add code here to query mode clock or hardware clock * and program max PWM appropriately. */ pr_warn_once("fixme: max PWM is zero\n"); return 1; } Looks PWM register can reconfig by kernel with mode clock, but kernel upstream didn't have this code until now. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
