Dark Screen - Turned off LCD Backlight in 13.37

Good morning,

As a fan of Salix 13.0.2a I welcomed the new 13.37 version and eagerly installed it in my laptop. It installed without any problems, right up to the log-in screen, after which, when the xfce desktop loads, the backlight of my LCD screen turned off. I am sure of this since I could still make out the new desktop background, icons and xcfe menu (very nice by the way) by lighting it up with a reading lamp.

There is a keyboard shortcut which can turn off and on my laptop. I did that too and noticed that the backlight briefly turned on but turned off again. Is this a kernel issue which affects only particular model of laptops? Is there a fix? (I notice the same behavior running a Mint 11 live dvd in this very laptop) As of now, I have 13.0.2a on my laptop but I really dig the new desktop of 13.37.

Laptop Specs:
Acer Aspire 4736z
T4200, Intel GMA 4500M
Bluetooth and Wifi (forgot brands)
2GB DDR3, 250GBHD
Dual booting WinXP and Salix OS 13.0.2a

Thank you. :)

Seems there is no fix yet. I did some workaround though.

I installed 13.37 in my desktop, where it installed without issues, copied its boot salix bitmap and backgrounds to my laptop and applied them to 13.0.2a. Fantastic, heheh :lol:

By the way, thanks for still supporting 13.0.2a. Just this morning I got an update to Opera.
Of course, nothing still beats k3b 1.0.5 found only in 13.0.2a. :mrgreen:

Can you try removing the xfce4-power-manager package?

at this time, I have 13.0.2a.
I will try that fix when I feel itchy enough to reinstall 13.37.
thanks a lot!
