mirek967 commented 11 years ago

I reported this 2 years ago on your Email, but I think its lost somewere on the way. I have an laptop with Nvidia Geforce 580M. On the card there are 2 outputs for Laptop displays they are called: LVDS, and EDP. Monitor is connected into eDP output. On the memory layout, there is area for LVDS (just as used in your driver), and another area for eDP output. I found that if I do following change -#define NV5X_PDISPLAY_SOR0_BRIGHTNESS 0x0000c084 +#define NV5X_PDISPLAY_SOR0_BRIGHTNESS 0x0000d084 in the file dkms_source_tree/nvidiabl-models.c Than it works well. I suppose, that this is problem of most of new laptops with recent graphic cards.

This is very interesting, I would like to be able to autodetect, could you give me the output of dmesg|grep nvidiabl with the c084 value? Maybe that if I detect all registers at 0 I can revert to EDP registers...

guillaumezin commented 11 years ago

Could you try version 0.81 and tell me if it works on your system?

guillaumezin commented 11 years ago

If 0.81 doesn't work, please retry with the following commands (still on version 0.81):

sudo modprobe -r nvidiabl sudo modprobe nvidiabl screen_type=3

Then tell me if it works and give me the output of dmesg|grep nvidiabl

Thank you !

I just installed version 0.81, and it works when screen_type is forced. When not forced, it is still detected as LVDS. But anyway, great work. Thank you.
