(II) RADEON(0): Validating modes on Primary head --------- (II) RADEON(0): Existing panel PLL dividers will be used. (WW) RADEON(0): Panel size 1024x768 is derived, this may not be correct. If not, use PanelSize option to overwrite this setting (II) RADEON(0): Panel infos found from DDC detailed: 1024x768 (II) RADEON(0): Valid Mode from Detailed timing table: 1024x768 (II) RADEON(0): Total of 1 mode(s) found. (II) RADEON(0): Total number of valid DDC mode(s) found: 1 (II) RADEON(0): Valid mode using on-chip RMX: 1024x768 (II) RADEON(0): Total number of valid FP mode(s) found: 1 [...] (II) RADEON(0): Modes for CRT1: ******************** (--) RADEON(0): Virtual size is 1024x768 (pitch 1024) (**) RADEON(0): *Mode "1024x768": 65.0 MHz (scaled from 0.0 MHz), 48.4 kHz, 60.0 Hz (II) RADEON(0): Modeline "1024x768"x0.0 65.00 1024 1048 1184 1344 768 771 777 806 (48.4 kHz) For the external output you indeed get only 640x480: (II) RADEON(0): Validating CRTC2 modes for MergedFB ------------ (II) RADEON(0): CRT2 Monitor: Using hsync range of 28.00-33.00 kHz (II) RADEON(0): CRT2 Monitor: Using vrefresh range of 43.00-72.00 Hz (II) RADEON(0): Clock range: 12.50 to 350.00 MHz (II) RADEON(0): Not using mode "1024x768" (hsync out of range) (II) RADEON(0): Not using mode "1024x768" (hsync out of range) [...] (II) RADEON(0): Modes for CRT2: ******************** (--) RADEON(0): Virtual size is 640x480 (pitch 640) (**) RADEON(0): Default mode "640x480": 25.2 MHz, 31.5 kHz, 59.9 Hz (II) RADEON(0): Modeline "640x480"x59.9 25.18 640 656 752 800 480 490 492 525 -hsync -vsync (31.5 kHz) This following seems to be the problem. (II) RADEON(0): Generating MergedFB mode list (II) RADEON(0): Clone mode, list all common modes (II) RADEON(0): Merged "640x480" (640x480) and "640x480" (640x480) to 640x480 (Clone) (--) RADEON(0): MergedFB: Virtual width 640 (--) RADEON(0): MergedFB: Virtual height 480 (**) RADEON(0): MergedFB: Display dimensions: 285x214 mm (**) RADEON(0): MergedFB: DPI set to (57, 56) I should definitely disable MergedFB by default. Can you verify that this will help by adding 'Option "MergedFB" "false"' to your xorg.conf (Section "Device")? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
