~$ cat /etc/X11/xorg.conf.nvidia-xconfig-original Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection
cat xorg.conf !!! trabalho (1920x1080) :
~$ cat /etc/X11/xorg.conf Section "ServerLayout" Identifier "Layout0" Screen 0 "Screen0" InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Unknown" HorizSync 30.0 - 80.0 VertRefresh 55.0 - 75.0 DisplaySize 400 225 Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync Option "DPMS" EndSection Section "Device" Identifier "Device0" BusID "PCI:1:0:0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection Section "Screen" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1920x1080_60.00" EndSubSection EndSection
Como obter: Modeline "1920x1080_60.00" 172.80 192 .... bla bla bla
~$ gtf 1920 1080 60 # 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
adicione isso na Seção "Monitor" e não se esqueça de adicionar na Seção "Tela" - > Subseção "Display" string Modos "1920x1080_60.00"
Para resumir:
- Especifique o HorizSync correto e VertRefresh
- Gen e adicione você Modeline
- Adicione o nome Modeline em Modes
Obrigado a todos por sua atenção !!!
