Hello Rolando,
I found that if you turn you computer in stanby (suspend to RAM) and
turn it on again, gmux work again.
I didn't found a way ot enable this behaviour at boot.
Best regards

Hello Rolando,
Do you use NVIDIA proprietary driver ?
If this is the case, this explain your issue probably. NVIDIA driver
seems disable gmux chips.
Best regards.

Hi,
I am currently experienced problems with the apple_gmux driver
while using a MBP retina 10,1.
System description & behavior:
-Ubuntu 13.04 with kernel 3.8-rc4.
-dmesg: apple_gmux: Found gmux version 3.2.19 [indexed]
-Under /sys/class/backlight I only have gmux_backlight.
-Under gmux_backlight both actual and max brightness are equal to 2^24
= 16777216,
while brightness value is within [0,1023] (the value can be changed)
-The backlight is dimmed throughout the boot process and remains the
same,
without being possible to adjust it.
If the following hack is applied then full brightness can be achieved,
however it remains nonadjustable.
#define HACK_VALUE 1023
...
In gmux_probe() :
...
props.max_brightness = gmux_read32(gmux_data,
GMUX_PORT_MAX_BRIGHTNESS);
//hack
props.max_brightness = HACK_VALUE;
....
bdev->props.brightness = gmux_get_brightness(bdev);
//hack
bdev->props.brightness = HACK_VALUE;
Does anybody have a clue to solve this problem?
Thanks for the help,
Rolando
