Hi, I am running 64 bit CentOS 6.5, and have an intermittent problem where the desktop crashes with the following error nouveau E[Xorg 6062]] failed to idle channel 0xccc0000 The only route I have out of it is to power down then restart. It is intermittent, where some days it does not happen, to 2-3 times per day. Have others had this experience and is there a solution? Thanks in advance for any help Best wishes Jan
