you need to use 185.xx with 2.2, you probably haven’t installed it correctly because it shouldn’t be working? unless you just installed the 2.2 SDK and left the 2.1 toolkit.
I couldn’t install driver version 185.xxx. I had a lot of problems trying to install it on Ubuntu 9.04, even I had to re-install Ubuntu because I couldn’t revert to 180.xxx back.
I’m using Toolkit 2.2 and SDK 2.2, driver 180.xxx
Probably I’m going to wait for some tutorial on how to install driver version 185.xxx on Ubuntu 9.04!
You cannot use 180.xx with 2.2 because 2.2 has a bunch of entry points that aren’t supported in 180. I wouldn’t be surprised if it returns feature not yet implemented for pretty much everything. I’m also kind of surprised CUDART even loads, I thought there was a check for that.
Anyway, it’s easy to get 185.xx on 9.04? It’s just
sudo CC=/usr/bin/gcc-4.3 ./driverinstaller or whatever
Nope, you cannot run it on a card that is running X. You will be halting execution of a kernel. So the GPU will be halted (and thus your X windows completely unresponsive)
