ATI, I think. I'll append xorg.conf (with comments deleted, to reduce its size a bit). > Radeon or Intel *should* detect a changed display I think. > You really shouldn't need to set modelines anymore. When setting up the previous monitor -- and the one before that -- it seemed necessary to remove unusable modelines from xorg.conf, else CtrlAlt+ and CtrlAlt- would set modes that produced a messed- up display or a blank screen. (The monitors' DDC reports -- or -configure's interpretation of them -- apparently included modes that would not actually work.) > Do keep in mind that since the front buffer is created at startup > time and can't currently be re-sized on the fly that you need to > set the virtual screen size to the maximum that you intend to use > or that will be the highest mode used (and displayed by xrandr). I had expected something along those lines, which is why I didn't expect to be able to _use_ 1920x1200 without restarting, but I'd still expect to be able to rerun the probe of the monitor and get the new report -- including the modelines that would have been generated if I had been running that probe "for real". ============================ xorg.conf ============================ Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "Files" RgbPath "/usr/X11R6/lib/X11/rgb" ModulePath "/usr/X11R6/lib/modules" FontPath "/usr/X11R6/lib/X11/fonts/misc/" FontPath "/usr/X11R6/lib/X11/fonts/TTF/" FontPath "/usr/X11R6/lib/X11/fonts/Type1/" FontPath "/usr/X11R6/lib/X11/fonts/CID/" FontPath "/usr/X11R6/lib/X11/fonts/75dpi/" FontPath "/usr/X11R6/lib/X11/fonts/100dpi/" EndSection Section "Module" Load "dbe" Load "dri" Load "extmod" Load "glx" Load "record" Load "xtrap" Load "freetype" Load "type1" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" EndSection Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psm0" Option "ZAxisMapping" "4 5 6 7" EndSection Section "Monitor" Identifier "Monitor0" VendorName "BTC" ModelName "LM-1702" Modeline "1280x1024" 108.00 1280 1328 1440 1688 1024 1025 1028 1066 +hsync +vsync Modeline "1024x768" 65.00 1024 1048 1184 1344 768 771 777 806 -hsync -vsync Modeline "800x600" 40.00 800 840 968 1056 600 601 605 628 +hsync +vsync Modeline "640x480" 25.20 640 656 752 800 480 490 492 525 -hsync -vsync Option "DPMS" EndSection Section "Device" Identifier "Card0" Driver "ati" VendorName "ATI" BoardName "3D Rage Pro AGP 1X/2X" ChipSet "ati" ChipId 0x4742 ChipRev 0x5c BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "Screen0" Device "Card0" Monitor "Monitor0" SubSection "Display" Viewport 0 0 Depth 1 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Viewport 0 0 Depth 4 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Viewport 0 0 Depth 8 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Viewport 0 0 Depth 15 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Viewport 0 0 Depth 16 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection EndSection
