Struggling with hardware...

[M T]

I'm still struggling with getting a setup that works for fault interpretation. Is anyone out there using a gaming laptop with two display adapters and two monitors and having no problems with OpendTect?  

One of my Acer monitors started to malfunction (the backlight went out), so I replaced both of them with a single Dell PQ2715Q. Now the polygon select is invisible.

I guess my question would be, if you're using a gaming laptop with the two adapter types listed below, and you are using dual monitors, what hardware are you using?

I can't really afford, at the moment, to build a new desktop with new monitors from scratch. And even if I did, now I'm afraid I'd spend a lot of money on a setup that didn't work with OpendTect.

Regards,

Mike

My first thought in reading this is that the Radeon is being used instead of the GeForce, and the issue you’re encountering is an AMD-specific driver bug. Assuming you’re using Windows, try this, shamelessly yanked and edited from a Google search:

Using the Nvidia Control Panel

1. Right-click an empty area on your desktop and open the Nvidia Control Panel.
2. On the left sidebar, click Manage 3D Settings.
3. Select the Program Settings tab.
4. Click the Add button and browse to locate OpendTect’s executable.
5. Under "Select the preferred graphics processor for this program," choose High-performance NVIDIA processor.
6. Click Apply in the bottom right corner.

See if that fixes it.

Hi Mike,

Yes, we tested OpendTect on gaming laptops with connected external screens and this setup works fine with OpendTect.

To expand on Matthew's answer: on hybrid AMD/NVIDIA laptops, Windows may sometimes start OpendTect on the integrated AMD GPU instead of the dedicated NVIDIA GPU. This can lead to rendering issues such as invisible polygon selection or other OpenGL display problems.

In your case I also notice that the NVIDIA driver is very recent, while the AMD Radeon driver appears to be from 2022. This suggests the issue may indeed relate to the AMD integrated graphics driver path.

We recommend configuring OpendTect to always use the high-performance NVIDIA GPU. A guide for this can be found in the OpendTect Administrator's Manual:

https://doc.opendtect.org/7.0.0/doc/admindoc/Default.htm#installation/opendtect/setup-the-preferred-gpu-with-windows-settings.htm?TocPath=2%2520Installation%257COpendTect%257C_____9

Additionally, if the issue persists, it may help to:

• Update the AMD Radeon integrated graphics driver
• Try both NVIDIA Studio and Game Ready drivers
• Test a different connection type (HDMI vs DisplayPort/USB-C), if possible
• Verify whether the external monitor is routed directly through the NVIDIA GPU or through the AMD iGPU path

The hardware itself should normally be more than capable of running OpendTect properly.

Best regards,

Arjan

Thank you for the helpful suggestions. I have decided to get a single large monitor (Samsung 34" Viewfinity S50GC series) and am running it off of my NVIDIA GPU. I hooked it up today and within the first couple of hours I managed to crash OpendTect. Don't worry - I sent in the crash report. It's a nice monitor and OpendTect seems to like it better, but if I crash OpendTect every couple of hours I might just go back to my cheap monitor as that might not necessarily be an improvement. It may not be the monitor's fault.

There is still some strangeness going on. For example, I can make the orientation axis disappear at will, even though the "Show Orientation Axis" button is on! (See attached screen captures). The observant among you will immediately see how I'm doing it. I'm curious to know if your systems exhibit similar behavior.

Regards,

Mike

Hi Mike,

Thanks for the update and for sending in the crash report.

One additional thing that may help users experiencing similar rendering instability or crashes on hybrid GPU laptops:

In OpendTect you can try disabling OpenGL shading via:

Utilities -> Settings -> Look & Feel -> Visualization

and then switch off OpenGL shading.

Additionally, if OpendTect is configured to use the NVIDIA GPU, it may also help to disable "Threaded Optimization" for OpendTect in the NVIDIA Control Panel.

These settings may reduce certain advanced rendering optimizations, but they can sometimes improve stability on systems where the OpenGL driver stack behaves unexpectedly.

It is good to hear that the new monitor already behaves better overall with OpendTect compared to the previous setup. Please keep us updated on whether the additional graphics-related changes improve stability over the next days.

Best regards,
Arjan
