    since a few days ago I cant get any new jobs
    and I keep geting this message on the event log:

    If we look into http://einstein.phys.uwm.edu//host_sched_logs/4142/4142843 it shows the following:

      Apparently your Client doesn't report a display driver version ("driver version required min: 26000, supplied: 0"). Anyone knows why? Is this a bug or a feature of 6.12.26, or maybe a problem with the driver?

        I cheked the driver, it's 267.44, clearly inside the requirements for running the wu.
        This is a toshiba laptop and the updates are made through thoshiba, not nvidia.
        I suspect toshiba suplies slightly different versions of the drivers, and that might be the reason the driver version is not being recognise .
        what is surprising is that this computer has been running einstein for some months now without any problems...
        Help appreciated

          Looking at your task list shows a few completed Cuda tasks Boinc using 6.12.26:

          Have you tried restarting windows since then? and have you changed driver versions since 11 October?

            The server side code has changed. It appears that the previous code allowed to send CUDA work to clients which didn't report a driver version. This, however, was unintentional.

            To understand how to deal with that I need to know under which conditions a Client doesn't report the driver version.

              I have not updated the driver manually, it might have been an automatic update.
              I am going to restart windows as it has been running for a few days and will get back.

                        My laptop host 3868392 is one of the ones which doesn't report a driver version. We used it as a testbed, and found that it's related to having multiple graphics adapters in the host. My laptop has Intel Optimus technology, with a low-power Intel HD graphics chipset for extended battery life when undemanding applications are running, and a NVIDIA GT420M for more demanding work.

                        The current BOINC driver detection logic sees that the first adapter isn't cuda-capable, and doesn't bother checking the others.

                        Our research led to David checking in http://boinc.berkeley.edu/trac/changeset/24046, but as with so much BOINC development, that change is only active in the highly experimental v6.13.xx versions, and hasn't been back-ported in to the bugfix updates of the current recommended line, like the v6.12.41 that I'm running now. You'll have to speak to David or Rom about that.
