--- Comment #13 from Adrien Prost-Boucle <adrien.prost-boucle at laposte.net> --- I tried with option radeon.dpm=0 and yes the message disappears at resume from sleep. But on my machine I never noticed graphics slowdown (at least with vlank_mode=0 glxgears). I'm not a consumer of fancy graphics or games. However what I noticed without that option was buggy scrolling in Firefox (and only Firefox). Sometimes all new tabs took like 5 seconds to unfreeze, and once unfreezed each tab remained responsive. Rather strange. I'll use the laptop for a few days to be sure it no longer happens. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
