https://bugs.freedesktop.org/show_bug.cgi?id=70388 --- Comment #34 from Linas Vepstas --- Please note: above trouble with today's rc kernel 3.18-rc2 is a *regression* from the stock kernel that comes w/ linux mint-qiana-17: Linux version 3.13.0-39-generic (buildd@toyol) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #66-Ubuntu SMP Tue Oct 28 13:30:27 UTC 2014 The stock kernel seems to mostly work fine-ish, for both 3D (i.e. blender) and youtube. Halting and restarting X does ggenerate the 'failed to idle' messages .. but since I never restart X, I can live w/it. BTW: noveau 2d rendering rocks, much faster than the nvidia drivers, which are noticeably laggy and slow for exactly the same hw & os setup. -- You are receiving this mail because: You are the assignee for the bug.
