xorg log. I am using X 1.7 now but had the exact same problem on 1.6
The message is harmless. You'll also so it on the first X startup after a cold boot in all likelihood. The cause isn't known exactly, but I suspect it's random garbage in the card's error reporting regs and not an actual error per se. I haven't been able to track down exactly how to avoid it as of yet. So, as long as everything works fine, ignore the message :) In my situation, it indeed looks totally harmless. Though pgraph errors seemed to be often associated with more severe problems in the past (as I found in irc log or in the bugtracker), so I was a bit unsure. Good to know I can safely ignore it :) For some reasons, it seems more likely to trigger after suspend/resume than on a fresh boot. I saw it many times after suspend/resume and only once after a cold boot. But well that probably does not help. Anyway, everything works fine, no big deal ! I didn't see these for a very long time. |

Created attachment 29993 [details] boot into X, first suspend/resume went fine, second suspend/resume triggered the PGRAPH_ERROR Almost every time I suspend/resume, a PGRAPH_ERROR appears in dmesg. I cannot see any bad consequences of it, but it doesn't seem normal so I thought I would report it.
