|
|
I'm using lxde and I made the following monitor.conf file but it doesn't work.
Code: | Section "Device"
Identifier "Radeon 9600"
Option "Monitor-VGA-0" "VGA screen"
EndSection
Section "Monitor"
Identifier "VGA screen"
Option "PreferredMode" "1440x900"
EndSection
|
as /etc/X11/xorg.conf.d/40-monitor.conf
The monitor is a CRT. |

It will probably work if you add the driver to the Device section, like:
Driver "..."
You may add Screen and ServerLayout sections in the same file if you need it. |

xrandr gui saved settings overwrite it on start-up or
EDID data have problems like this exsample: Xorg0.log
Code: | (II) DRIVER(0): Not using mode "1440x900" (bad mode clock/interlace/doublescan)
(II) DRIVER(0): Modeline "1440x900""x60.0 * * * * * * * * * +hsync +vsync (64.0 kHz UP)
(II) DRIVER(0): ... |
Then add the Modeline under Monitor section to force it to use
Code: | Option "PreferredMode" "1440x900"
Modeline "1440x900" * * * * * * * * * +hsync +vsync |
Device Driver is not required is a general option.
And check VGA-0 is properly |

Are you actually sure the monitor supports 1440x900? I seriously doubt there are 16:10 CRTs around. |

Gusar
I put the 1440x900 as an indicator to see if monitor.conf is in effect or not. I will change it to reasonable value when monitor.conf is taking control.
The solutions mentioned above : I will try and post the results here.
Thanks |

It might work better if you use a real modeline:
Code: | # 1440x900 59.89 Hz (CVT 1.30MA) hsync: 55.93 kHz; pclk: 106.50 MHz
Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync |
And judging by that xorg log output you also appear to have put the line «Device "Driver"» in the config file, which is complete nonsense.
Fix those two errors then try again. |

If 1440x900 is not your goal, what exactly is it that you want to do? By default, no config is necessary. If you want to set a resolution lower than the display's max, you don't need a Device section at all, just a Monitor section, with the Identifier being the output name. Code: | Section "Monitor"
Identifier "VGA-0"
Option "PreferredMode" "1024x768"
EndSection |
If the resolution doesn't exist yet, use a Modeline, but it needs to have a unique name. Code: | Section "Monitor"
Identifier "VGA-0"
Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 -HSync +Vsync
Option "PreferredMode" "1024x768_85.00"
EndSection |

Gusar I want to control the monitor through monitor.conf but lxde's "preferences" --> "monitor settings" takes the control and my monitor.conf doesn't work.
I'm trying to overcome this.
(Itried the modeline suggestion too but still no good)
Thanks |
