When I take a screenshot with 'scrot' i get a file like this : 2009-03-18-104527_1360x768_scrot.png. But in the Xorg.0.log it clearly shows the resolution of the TV itself : term004# cat /var/log/Xorg.0.log | grep 1360 term004# cat /var/log/Xorg.0.log | grep 1280 (II) RADEON(0): Panel infos found from DDC detailed: 1280x720 (II) RADEON(0): h_active: 1280 h_sync: 1390 h_sync_end 1430 h_blank_end 1650 h_border: 0 (II) RADEON(0): h_active: 1280 h_sync: 1390 h_sync_end 1430 h_blank_end 1650 h_border: 0 (II) RADEON(0): Output DVI-0 using initial mode 1280x720 Mode 1280x720 - 1650 750 5 Mode 1280x720 - 1650 750 5 (II) RADEON(0): Modeline "1280x720"x0.0 74.25 1280 1390 1430 1650 720 725 730 750 +hsync +vsync (45.0 kHz) (II) RADEON(0): h_active: 1280 h_sync: 1390 h_sync_end 1430 h_blank_end 1650 h_border: 0 I tried 'xrandr' in my .xinitrc file, which only affect my screenshots... I also tried Prefered Mode in the Xorg conf, no effects. Any tips would be very appreciated ! Thanks. Francis Dubé
