Bug #: 48197 Summary: DVI monitor connected to an Ati x1550 on standard resolution blinks. Classification: Unclassified Product: DRI Version: unspecified Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: major Priority: medium Component: DRM/Radeon AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: ter4py@gmail.com
Created attachment 59380 --> https://bugs.freedesktop.org/attachment.cgi?id=59380 dmesg from fedora 16
I have an Ati radeon x1550, and connected to that a DVI monitor (and another to the VGA, but this bug is present also when only the DVI monitor is connected) This bug appears in every distribution and kernel I tried, the last one is fedora 16, but I tried debian 6 too and Archlinux with the latest kernel. Description of problem: DVI screen, if on standard resolution (1680x1050) blinks from the tty to the Gnome dekstop, and especially when something like Firefox is made fullscreen: I recorded a video to explain this better: https://www.youtube.com/watch?v=8Tcjb6p0Yi4

--- Comment #4 from Alex Deucher agd5f@yahoo.com 2012-04-02 08:11:53 PDT --- Does it only blink on the 1680x1050 mode or all modes on the DVI monitor?

--- Comment #5 from ter4py@gmail.com 2012-04-02 08:25:14 PDT --- Only in the 1680x1050 mode that way. But it might happen very rarely on 1480x900. I'm not sure about this though, it didn't happen recently. (In reply to comment #4)
