http://bugs.freedesktop.org/show_bug.cgi?id=14722 Summary: dual monitor flicker and loss of signal Product: xorg Version: 7.3 Platform: x86 (IA32) OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/radeonhd AssignedTo: lverhaegen@suse.de ReportedBy: dhalik@jla.rutgers.edu QAContact: xorg-team@lists.x.org We've recently upgraded all the workstations in my department to nice new HP machines with X1600XT PCIe cards (RV530 chipset I think), dual 24" HP LP2465 monitors, and Fedora 8. So far they've worked great with the RadeonHD 1.1 drivers, until we went to an extended desktop and started using them full time. On all of our machines the right display (i.e. second display) has a weird flicker problem. Every few minutes horizontal black lines will randomly flash quickly across the screen, and maybe once an hour the screen completely looses its signal for about a second and then comes back on. I've ruled out the monitors or the videocard/workstation at this point. Also, the fact that it happens on all the machines leads me to believe its a driver issue not faulty hardware. Using the same monitors and RadeonHD release on my X1650 AGP in an older workstation never exhibited the problem once. I'm guessing it's this particular chipset or maybe the fact that it's dual DVI out. The AGP card without the problem is VGA/DVI. The issue is always in the secondary port. From xrandr: DVI-I_2/digital connected 1920x1200+1920+0 519mm x 324mm 1920x1200 60.0*+ I've been looking at Bug #13853 and it seems similar, but I'm not experiencing the permanent loss of signal, it always returns immediately. Also, I'm using xorg-x11-drv-radeonhd-1.1.0-0.6.20080216git.fc8 which is supposedly built after the fixes in #13853 were applied, so it must be a separate or related issue. Please let me know if there is any testing I can do, I'd love to help. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Easiest way to do this is to start a 'naked' Xserver from a text mode console. Just do: X -logverbose 7 then kill X with Ctrl-Alt-Backspace. Reassigning to reporter for feedback.

...

From the list of modes used:

(II) RADEONHD(0): Modeline "1920x1200"x60.0 154.00 1920 1968 2000 2080 1200 1203 1209 1235 +hsync -vsync (74.0 kHz) (II) RADEONHD(0): Modeline "1600x1200"x59.9 161.00 1600 1709 1880 2160 1200 1203 1207 1245 -hsync +vsync (74.5 kHz) (II) RADEONHD(0): Modeline "1680x1050"x59.9 147.00 1680 1787 1966 2252 1050 1053 1059 1089 -hsync +vsync (65.3 kHz) (II) RADEONHD(0): Modeline "1600x1000"x59.9 133.00 1600 1699 1869 2138 1000 1003 1009 1038 -hsync +vsync (62.2 kHz) (II) RADEONHD(0): Modeline "1280x1024"x84.9 159.75 1280 1375 1513 1746 1024 1027 1034 1078 -hsync +vsync (91.5 kHz) (II) RADEONHD(0): Modeline "1280x1024"x75.0 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync (80.0 kHz) (II) RADEONHD(0): Modeline "1280x1024"x59.9 109.00 1280 1361 1496 1712 1024 1027 1034 1063 -hsync +vsync (63.7 kHz) (II) The first mode (1920x1200) is the one used on startup. I wonder whether one gets output or not depends on the pixel clock. There are a number of 1280x1024 modes available with pixel clocks ranging from 109 to 159 MHz (giving refresh rates between 60 and 85 MHz. David, could you use xrandr (logged in from remote but connected to the Xserver in question) to set a 1280x1024 mode and test different refresh rates? Reassigning to reporter for feedback. David, please assign back to me when done.

I did verify that the monitor was indeed running at each rate. I believe they were 59.9 75.0 and 84.9. However, in that same period, when I was running at native resolution 1920x1200 @ 60.0, I didn't experience any problems either. Sometime it flickers and turns off a ton of times in thirty minutes, other days I can go a couple hours without an issue. So that isn't the best debugging method. Any ideas on a better way to accomplish this? I guess I can run it for a full day with each mode and rate at work. That will take me some time to get back to you though ;) Thoughts? -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org
