https://bugzilla.novell.com/show_bug.cgi?id=427645 Summary: Xorg does a DDC scan every 10 seconds Product: openSUSE 11.0 Version: Final Platform: x86 OS/Version: openSUSE 11.0 Status: NEW Severity: Normal Priority: P5 - None Component: X.Org AssignedTo: sndirsch@novell.com ReportedBy: auxsvr@yahoo.com QAContact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Created an attachment (id=240499) --> (https://bugzilla.novell.com/attachment.cgi?id=240499) Xorg log I'm using xorg-x11-7.4-4.1 and xorg-x11-driver-video-7.4-1.5 from the Xorg repository. Every 10 seconds Xorg freezes for ~1 second, i.e. keyboard input and display are delayed. It appears that Xorg performs a DDC scan every 10 seconds, because after the freeze the following is added to Xorg.0.log: (II) RADEON(0): EDID vendor "HTC", prod id 40000 (II) RADEON(0): Using hsync ranges from config file (II) RADEON(0): Using vrefresh ranges from config file (II) RADEON(0): Printing DDC gathered Modelines: (II) RADEON(0): Modeline "1152x864"x0.0 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync (67.5 kHz) (II) RADEON(0): Modeline "1280x1024"x0.0 108.00 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync (64.0 kHz) (II) RADEON(0): Modeline "800x600"x0.0 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync (37.9 kHz) (II) RADEON(0): Modeline "800x600"x0.0 36.00 800 824 896 1024 600 601 603 625 +hsync +vsync (35.2 kHz) (II) RADEON(0): Modeline "640x480"x0.0 31.50 640 656 720 840 480 481 484 500 -hsync -vsync (37.5 kHz) (II) RADEON(0): Modeline "640x480"x0.0 31.50 640 664 704 832 480 489 491 520 -hsync -vsync (37.9 kHz) (II) RADEON(0): Modeline "640x480"x0.0 30.24 640 704 768 864 480 483 486 525 -hsync -vsync (35.0 kHz) (II) RADEON(0): Modeline "640x480"x0.0 25.20 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz) (II) RADEON(0): Modeline "720x400"x0.0 35.50 720 738 846 900 400 421 423 449 -hsync -vsync (39.4 kHz) (II) RADEON(0): Modeline "720x400"x0.0 28.32 720 738 846 900 400 412 414 449 -hsync +vsync (31.5 kHz) (II) RADEON(0): Modeline "1024x768"x0.0 78.80 1024 1040 1136 1312 768 769 772 800 +hsync +vsync (60.1 kHz) (II) RADEON(0): Modeline "1024x768"x0.0 75.00 1024 1048 1184 1328 768 771 777 806 -hsync -vsync (56.5 kHz) (II) RADEON(0): Modeline "1024x768"x0.0 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync (48.4 kHz) (II) RADEON(0): Modeline "1024x768"x0.0 44.90 1024 1032 1208 1264 768 768 776 817 interlace +hsync +vsync (35.5 kHz) (II) RADEON(0): Modeline "832x624"x0.0 57.28 832 864 928 1152 624 625 628 667 -hsync -vsync (49.7 kHz) (II) RADEON(0): Modeline "800x600"x0.0 49.50 800 816 896 1056 600 601 604 625 +hsync +vsync (46.9 kHz) (II) RADEON(0): Modeline "800x600"x0.0 50.00 800 856 976 1040 600 637 643 666 +hsync +vsync (48.1 kHz) (II) RADEON(0): Modeline "1152x864"x0.0 108.00 1152 1216 1344 1600 864 865 868 900 +hsync +vsync (67.5 kHz) (II) RADEON(0): Modeline "640x480"x85.0 35.71 640 672 736 832 480 481 484 505 -hsync +vsync (42.9 kHz) (II) RADEON(0): Modeline "800x600"x85.0 56.55 800 840 928 1056 600 601 604 630 -hsync +vsync (53.5 kHz) (II) RADEON(0): Modeline "1024x768"x85.0 94.39 1024 1088 1200 1376 768 769 772 807 -hsync +vsync (68.6 kHz) (II) RADEON(0): Modeline "640x480"x70.0 28.56 640 664 728 816 480 481 484 500 -hsync +vsync (35.0 kHz) (II) RADEON(0): Modeline "1280x960"x60.0 102.10 1280 1360 1496 1712 960 961 964 994 -hsync +vsync (59.6 kHz) (II) RADEON(0): Modeline "1024x768"x60.0 64.11 1024 1080 1184 1344 768 769 772 795 -hsync +vsync (47.7 kHz) (II) RADEON(0): Output: VGA-0, Detected Monitor Type: 1 (II) RADEON(0): EDID data from the display on output: VGA-0 ---------------------- (II) RADEON(0): Manufacturer: HTC Model: 9c40 Serial#: 0 (II) RADEON(0): Year: 2003 Week: 10 (II) RADEON(0): EDID Version: 1.1 (II) RADEON(0): Analog Display Input, Input Voltage Level: 0.700/0.700 V (II) RADEON(0): Sync: Separate (II) RADEON(0): Max Image Size [cm]: horiz.: 33 vert.: 25 (II) RADEON(0): Gamma: 2.22 (II) RADEON(0): DPMS capabilities: StandBy Suspend Off;

I've also tried running without any gtk programs to no avail.
