It's limiting the modes since it specifies a max pix clock of 110 Mhz and the pix clock of the 1280x1024 mode is 135 Mhz: (II) RADEON(0): 1280x1...@75hz Modeline "1280x1024"x0.0 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync (80.0 kHz) Ranges: V min: 50 V max: 120 Hz, H min: 30 H max: 72 kHz, PixClock max 110 MHz To override, you need to specify the modeline for the preferred mode in your xorg.conf monitor section, e.g.,: Modeline "1280x1024" 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync Option "PreferredMode" "1280x1024" You can also manually add the modeline at runtime with xrandr: xrandr --newmode "1280x1024" 135.00 1280 1296 1440 1688 1024 1025 1028 1066 +hsync +vsync xrandr --addmode VGA-0 "1280x1024" xrandr --output VGA-0 --mode "1280x1024" If the 1280x1024 mode works, then we probably need an edid quirk for your monitor in the xserver. -- Configure bugmail: http://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
