--- Comment #12 from Alex Deucher <[email protected]> 2012-01-30 07:32:25 PST --- There are two 1680x1050 modes in the EDID: 1. 1680x1050 @ 146.25 Mhz [ 117.660] (II) RADEON(0): #2: hsize: 1680 vsize 1050 refresh: 60 vid: 179 [ 117.661] (II) RADEON(0): Modeline "1680x1050"x60.0 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync (65.3 kHz) 2. 1680x1050 @ 119.00 Mhz [ 117.660] (II) RADEON(0): clock: 119.0 MHz Image Size: 474 x 296 mm [ 117.660] (II) RADEON(0): h_active: 1680 h_sync: 1728 h_sync_end 1760 h_blank_end 1840 h_border: 0 [ 117.660] (II) RADEON(0): v_active: 1050 v_sync: 1053 v_sync_end 1059 v_blanking: 1080 v_border: 0 [ 117.661] (II) RADEON(0): Modeline "1680x1050"x59.9 119.00 1680 1728 1760 1840 1050 1053 1059 1080 +hsync -vsync (64.7 kHz) The 119Mhz mode is the monitor's preferred mode. The problem seems to be the monitor doesn't seem to care for the 146.25Mhz mode while the 119Mhz mode works fine. For some reason UMS doesn't add the 146.25Mhz mode (possibly the xserver doesn't add 1680x1050 modes in the standard timing block); with KMS, the kernel parses the EDID and adds the 146.25Mhz mode. Does switching to a different mode on the problematic display fix it? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
