Kubuntu Intrepid with ATI FireGl 8800 card (r200 chip) lspci: 01:00.0 VGA compatible controller: ATI Technologies Inc Radeon R200 QH [Radeon 8500] (rev 80) My monitor model is an HP p1120 -HorizSync 30-121 -VertRefresh 48-160 Since I installed intrepid I have a temblor in my monitor (In the other Ubuntu releases it works great). It is especially visible at the edges of the windows. It is very strange because all seems to be correct (with the default xorg.conf configuration): - Resultion is on the default 1600x1200 - The vertical refresh rate is on the default 85Hz - The horizontal refresh rate is on 106.3kHz I try to configure the HorizSync and VertRefresh manually editing the /etc/X11/xorg.conf file but nothing changes In Windows with the same settings (1600x1200 - 106.3kHz/85Hz) there is no tremor Please see the bug reported in launchpad: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/313525
Of particular interest is that the "DDC gathered Modelines" are a bit different in the working and not working case: -(II) RADEON(0): Modeline "1800x1440"x80.0 298.50 1800 1944 2136 2472 1440 1443 1450 1510 -hsync +vsync (120.8 kHz) -(II) RADEON(0): Modeline "1600x1200"x75.0 204.75 1600 1720 1888 2176 1200 1203 1207 1255 -hsync +vsync (94.1 kHz) -(II) RADEON(0): Modeline "1280x1024"x84.8 159.50 1280 1376 1512 1744 1024 1027 1034 1078 -hsync +vsync (91.5 kHz) -(II) RADEON(0): Modeline "1024x768"x84.9 94.50 1024 1096 1200 1376 768 771 775 809 -hsync +vsync (68.7 kHz) -(II) RADEON(0): Modeline "800x600"x84.9 56.75 800 848 928 1056 600 603 607 633 -hsync +vsync (53.7 kHz) -(II) RADEON(0): Modeline "640x480"x84.6 35.00 640 664 728 816 480 483 487 507 -hsync +vsync (42.9 kHz) +(II) RADEON(0): Modeline "1800x1440"x80.0 299.95 1800 1944 2144 2488 1440 1441 1444 1507 -hsync +vsync (120.6 kHz) +(II) RADEON(0): Modeline "1600x1200"x75.0 205.99 1600 1720 1896 2192 1200 1201 1204 1253 -hsync +vsync (94.0 kHz) +(II) RADEON(0): Modeline "1280x1024"x85.0 159.36 1280 1376 1512 1744 1024 1025 1028 1075 -hsync +vsync (91.4 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 "800x600"x85.0 56.55 800 840 928 1056 600 601 604 630 -hsync +vsync (53.5 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 "1800x1440"x80.0 298.50 1800 1944 2136 2472 1440 1443 1450 1510 -hsync +vsync (120.8 kHz) -(II) RADEON(0): Modeline "1600x1200"x75.0 204.75 1600 1720 1888 2176 1200 1203 1207 1255 -hsync +vsync (94.1 kHz) -(II) RADEON(0): Modeline "1280x1024"x84.8 159.50 1280 1376 1512 1744 1024 1027 1034 1078 -hsync +vsync (91.5 kHz) -(II) RADEON(0): Modeline "1024x768"x84.9 94.50 1024 1096 1200 1376 768 771 775 809 -hsync +vsync (68.7 kHz) -(II) RADEON(0): Modeline "800x600"x84.9 56.75 800 848 928 1056 600 603 607 633 -hsync +vsync (53.7 kHz) -(II) RADEON(0): Modeline "640x480"x84.6 35.00 640 664 728 816 480 483 487 507 -hsync +vsync (42.9 kHz) +(II) RADEON(0): Modeline "1800x1440"x80.0 299.95 1800 1944 2144 2488 1440 1441 1444 1507 -hsync +vsync (120.6 kHz) +(II) RADEON(0): Modeline "1600x1200"x75.0 205.99 1600 1720 1896 2192 1200 1201 1204 1253 -hsync +vsync (94.0 kHz) +(II) RADEON(0): Modeline "1280x1024"x85.0 159.36 1280 1376 1512 1744 1024 1025 1028 1075 -hsync +vsync (91.4 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 "800x600"x85.0 56.55 800 840 928 1056 600 601 604 630 -hsync +vsync (53.5 kHz) +(II) RADEON(0): Modeline "640x480"x85.0 35.71 640 672 736 832 480 481 484 505 -hsync +vsync (42.9 kHz)
I've installed latest ati drivers in a ubuntu 8.04.2 live CD. All work fine.That should prove that the regression really is in the xorg-server and not in the ati driver, since both old and new ati drivers work in Hardy. See https://bugs.launchpad.net/bugs/313525 for more details
Tried in Ubuntu jaunty (9.04) with latest updates and the problem persist xorg version: Version: 1:7.4~5ubuntu18
Tried in latest Ubuntu Karmic (9.10) and the problem persist xserver-xorg-core version: Version: 2:1.6.3-1ubuntu4
The tremor is only in 1600x1200 resolution. The others resolutions works well
Tested in 1.6.4 version and the bug is still valid
Tested with 1.7.99.2~git20091211 and the bug is still valid
Can you provide a server log for a working state and a broken state for comparison? What version change introduces the problem? A new radeon driver or a new server?
The reporter answered these questions in comment 2. The logs in the downstream bug indicates it broke between xserver 1.4.0.90 and 1.5.2.
Mass closure: This bug has been untouched for more than six years, and is not obviously still valid. Please file a new report if you continue to experience issues with a current server.
