--- Comment #17 from Alexandre Demers <alexandre.f.demers at gmail.com> --- I'm about to test patches. But before, as promised, here are the values retrieved read and written to the registers. By the way, I have only a single monitor. tmp = RREG32(EVERGREEN_CRTC_CONTROL + crtc_offsets[i]); -> 272696081 (0001 0000 0100 0001 0000 0011 0001 0001) tmp |= EVERGREEN_CRTC_DISP_READ_REQUEST_DISABLE; -> 289473297 (0001 0001 0100 0001 0000 0011 0001 0001) So, it is set as you explained me earlier. I'll be back soon with some news from the patches. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
