Hi Mats

That's really important information if you are using v5.3 software. This is over a year old, and was not tested on the switchable graphics laptop you have. I would expect problems with v5.3 on this laptop.

This release did not support DX10 on the system you have, and also does not have switchable graphics support, so there probably would be issues.

Can you (and everyone posting in this thread) make sure that v5.6 M1 from the DisplayLink website installed. The version of "DisplayLink Core Software" in Control Panel->Programs should be 5.6.31870.0.

At least then we will be testing the same software.

Thanks

Wim

Hi Wim,
The DisplayLink Core software shows 5.6.31854.0
but the DisplayLink Graphics is 5.6.31870.0
Is that correct?

I'm going away for a week now but will get back with an update if the problem is solved.

Thanks,
Mats

I just reinstalled the software. Mine shows the same as Mats.

OK - that looks good for both of you. The Core version of software is the important bit, as that's the "brains" of the driver. The other part is the version of the branding information for devices.

Could you also enable the BSOD trick to collect a crash dump, although it looks like the PC may be too frozen for this to happen. Could you check that the BSOD keypress is enabled by trying it when the PC is not frozen (but you have nothing important open :-) )

Thanks

Wim

I have the same issue with 2 HP dv6z notebooks. They will freeze forcing me to remove the battery or hold down the power switch to reboot. When they freeze even disconnecting the docking station or unplugging the power cord from it does nothing.

The issue seems to be limited to the display driver, disabling it and plugging the monitor directly to the notebook eliminates the issue all together.

Hi Wim,
We have tested with the latest software for a week now and the problem still exist.
Even though my collegue thinks it might be less frequent.

The BSOD has been enabled and tested when not frozen but unfortunately it does not work when the freeze happens.

Is there anything else I can assist with in the troubleshooting?

We still have the same issue. When the notebook freezes there is no dump file.

We've still not managed to reproduce this freeze on our HP laptops in our system test lab.

I have just released our v6.0 software on the forum, which not only contains support for our new chips, but also has bug fixes and some rearchitecture. This may indirectly fix the lockups you are seeing.

I'd appreciate it if you could try this software build and see if the freezing issue "goes away"

If it still occurs in this, then we'll look into making a special build to try and give more information on the freeze.

Thanks

Wim

Any update on v6.0? Does it fix this issue for the users on this thread?

Thanks

Wim
