Monitor gets no signal from Quadro K2100M @ ThinkPad W540 with 337.19 driver

kohr_h · May 18, 2014, 2:08pm

Hi! The Quadro K2100M in my W540 laptop refuses to provide the built-in monitor with a usable signal. This refusal comes in several steps:

If I use a minimal xorg.conf just forcing X to use the nvidia driver, the card isn’t even recognized:

NOTE: This is an output with an older driver version, let me provide a newer one.

If I add the BusID option to pinpoint the graphics card, the driver fails to acquaint a usable monitor configuration:

Forcing the driver to treat DFP as connected monitor by applying the “ConnectedMonitors” “DFP” option results in failure to read its EDID info:

Finally, providing a custom EDID (extracted from a working X session with a different driver using the read-edid tool [[url]Best Online Casinos Canada | Top Canadian Gambling Sites 2022]), X starts normally, but still without any signal sent to the screen:

The (text format) EDID file looks like this:

EISA ID: CMN15c0
EDID version: 1.4
EDID extension blocks: 0
Screen size: 34.4 cm x 19.4 cm (15.55 inches, aspect ratio 16/9 = 1.77)
Gamma: 2.2
Digital signal

    # Monitor preferred modeline (60.0 Hz vsync, 68.3 kHz hsync, ratio 16/9, 141 dpi)
    ModeLine "1920x1080" 151.6 1920 2010 2070 2220 1080 1086 1095 1138 -hsync -vsync

I’m not really sure if the error is on the driver side, but the fact that other drivers like “fbdev” or “modesetting” work normally points to that.

Would be great if someone could help me out with this. Maybe this is a known issue with a workaround??

Some system details:
OS: Sabayon Linux

X server: 1.14.6
Nvidia driver: 337.19

The verbose X log output (X -logverbose 6) suggests that none of the two detected display devices (DFP-0 and DFP-1) represent the monitor:

[ 529.713] (–) NVIDIA(0): DFP-0: DFP is not internal to notebook
…
[ 529.713] (–) NVIDIA(0): DFP-1: DFP is not internal to notebook

So probably the internal monitor is not detected at all, and the failure of forced DFP output is no surprise either.

Physically, the graphics card has a DisplayPort connector, so the “Internal DisplayPort” associated with DFP-1 supposedly relates to it (despite the “internal” attribute).
On the other hand, the DFP-0 “Internal TMDS” seems to be an internal HDMI connection since there is no external HDMI port.

One more detail: the command “nvidia-xconfig --query-cpu-info” returns zero detected display devices:

I think your laptop is Optimus try Chapter 18. Using the NVIDIA Driver with Optimus Laptops

kohr_h · June 3, 2014, 3:36pm

Thanks, but I have only one graphics card. However, I haven’t checked if some of the Optimus instruction may be helpful anyway…

kohr_h · June 5, 2014, 2:02pm

The issue is still present with the current 337.25 driver. See attached log files.

From your bug report log:

/sbin/lspci -nn

You have two video controllers. The Intel GPU is on CPU. You have an Optimus. It looks like Lenovo has removed the option to disable Optimus in UEFI, too: https://forums.lenovo.com/t5/W-Series-ThinkPad-Laptops/W540-Disabling-Optimus-in-BIOS-UEFI-gone/td-p/1463401.

You’re going to have to either setup Bumblebee or the randr 1.4 offloading for Optimus as described in the docs.

kohr_h · June 9, 2014, 7:47pm

Oops. Thanks, at least something to start with.
Confusing that only one GPU is reported…
