Linux backlight driver

[guillaumezin]

Hello,

I updated the driver (see first post of the topic) a way that will be easier for me to maintain. I added some laptop models but it needs further testing. Feedback is welcome.

Thank you very much!! Thats perfect.

But you've added wrong values for min. and max. brightness for VAIO VPCCW1S1E. The values are: min= 7000 and max= 2500000. And another problem on these VAIO model are the scripts you've added. The script doesn't changed the brightness correctly. I had to use oBacklight to get everything working. But now it's perfect. Thanks.

I only wanted to tell you that, because maybe you could fix this in your release!

Thank you, this is corrected in the 0.54 version. And I added a link to the oBacklight script.

Would it also be possible to provide an version that is compatible with Ubuntu 10.04. Because i can't compile this version under Ubuntu 10.04. But if you have changed the values i posted before, it isn't even necessary any more. Just wanted to compile it by myself to change the wrong values.

[vagopestoso]

I can't build it on ubuntu 10.04 either.
This is what I get:

Yeah thats right. You can't compile it on Ubuntu 10.04. It would be great if there would exist a version for it.

Hello,

The 0.55 version should compile on Ubuntu 10.04 too, but I tested it only on Ubuntu 10.10. Feedback is welcome.

The complete VPCCW1 family should be supported now.

[theone123]

Ok i didn't try to compile it on Ubuntu 10.04, but i installed the precompiled package. This works very great so far. So I believe you should also be able to compile it. Can't see any bug. Very well done. Thank you.

Version 0.55 worked fine for me with 10.04.

It doesn't work with all Sony VPCCW1* laptops, however. I had to make the following changes to get it working for my Sony VPCCW17FX (NVidia g210m):

nvidiabl-laptops.h:

// This has to be BEFORE the general VPCCW1 line
NVIDIABL_DECLARE_LAPTOP_MODEL("Sony Corporation", "VPCCW17FX", 0x0a74, 0, 1024, 127000),
NVIDIABL_DECLARE_LAPTOP_MODEL("Sony Corporation", "VPCCW1", 0x0a2a, 0, 7000, 2500000),

nvidiabl-models.c:

/* NVIDIA Quadro FX 470 */
{ PCI_VDEVICE(NVIDIA, 0x087f), (kernel_ulong_t)&nv5x_driver_data },
/* NVIDIA GeForce 210M */
{ PCI_VDEVICE(NVIDIA, 0x0a74), (kernel_ulong_t)&nv5x_driver_data },
/* NVIDIA GeForce 230M */
{ PCI_VDEVICE(NVIDIA, 0x0a2a), (kernel_ulong_t)&nv5x_driver_data },

Now if i could only get it to not conflict with the sony-laptop module it would be perfect

Annexed a small patch adding support for the Sony VAIO VPCS13V9E model. The min/max values are empirical, but seem ok to me.

[guillaumezin]

0.56 version incorporates Sony VAIO VPCS13V9E and Sony VPCCW17FX (NVidia g210m).

Thank you for your patches !
