Hi, Using 3 monitors on the GeForce GTX 650 Ti card (2 DVI and 1 VGA) works great out of the box on Fedora 20. However, every couple of days the graphics driver seems to crash. The same thing used to happen when 2 monitors were in use, but that has pretty much stabilized as of late. Does anyone have a stable setup with this card using 3 monitors? Will 3 monitors be supported? Thanks, Rob $ uname -r 3.17.4-200.fc20.x86_64 $ lspci | grep Ti 01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 650 Ti] (rev a1) $ dmesg [141447.170973] traps: polkitd[9707] general protection ip:7f383508c022 sp:7fffdd1ac110 error:0 in libmozjs-17.0.so[7f3834f4d000+3b3000] [141869.521246] nouveau E[ PFIFO][0000:01:00.0] SCHED_ERROR [ CTXSW_TIMEOUT ] [141869.521258] nouveau E[ PFIFO][0000:01:00.0] PGRAPH engine fault on channel 4, recovering...

Well, I downgraded back to 2 monitors and it turns out that this problem has reappeared when using only 2 monitors as well. There must have been a regression of some sort somewhere along the line, possibly in one of the latest kernels? What can I provide to help this issue get fixed? -Rob> On Dec 5, 2014, at 8:07 AM, Rob Jansen <rob.g.jansen at nrl.navy.mil> wrote: > > Hi, > > Using 3 monitors on the GeForce GTX 650 Ti card (2 DVI and 1 VGA) works great out of the box on Fedora 20.

There were fixes in 3.17 that were supposed to help this, but apparently they didn't help enough. See https://bugs.freedesktop.org/show_bug.cgi?id=72180 -- basically some sort of card setup failure on our part is causing our ctxsw to die, but nvidia's appears to be more resilient to the screwups.
