Hi to everyone,

sorry for my bad English, but I've a problem and I can't find any solution, so I've open a new post.

On my PC:

M4N82 Deluxe, AMD Phenom II1055T 9850 + Zalman CNPS9500, 8Gb DDR II 800 Corsair, Sil 3124 PCI-E, RAID1 2 x WD740ADFD + RAID1 2 x WD5000AAKS, PNY GTS 450 1Gb, Ubuntu 10.4 64 Bit

When I start BOINC on message I read:

No usable GPUs found


But if I restart the boinc-client as follow:

sudo /etc/init.d/boinc-client restart
 * Stopping BOINC core client: boinc                                     [ OK ] 
 * Starting BOINC core client: boinc                                     [ OK ] 
 * Setting up scheduling for BOINC core client and children:                    
                                                                         [ OK ]


Then BOINC can recognize my graphic card:

NVIDIA GPU 0: GeForce GTS 450 (driver version unknown, CUDA version 3020, compute capability 2.1, 1023MB, 401 GFLOPS peak)


Other info:

BOINC version: 6.10.58
nVidia driver: 260.19.29
Kernel: 2.6.32-27-generic x86_64

The problem is only on this computer, in other system the graphics card (like Quadro NVS290) is recognized immediately.
Any idea about ?

Thanks to all.

Maybe it helps to insert a sleep statement into your startup script. And make sure that BOINC is started after the graphics initialisation.

See also this thread.

Thanks for your reply.

I've some trouble to apply the patch shown in the link, but I hope that in next day I can test this solution.

WoW

I've solve the problem adding a delay in the boinc-client script like:

start()
{
  log_begin_msg "Starting $DESC: $NAME"
  if is_running; then
    log_progress_msg "already running"
  else
    sleep 1m


Thank for all ....
