[Yupy]

Hello my monitor has a native 1440x900 rezolution and it's not showing in my graphics card nVidia 9600GT that I use in this PC i've tried from the nVidia control panel to set it up manually but not showing properly I want to mention I did encounter this problem on win7 but I was able to set it from the nVidia control panel... any idea how to make the native rez. work ?

Please generate an overview of your system like this:
- launch a terminal window and make it full screen, to avoid chopped lines;
- copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Would you post some additional information.

1. Use this command in the Terminal: xrandr

2. What is the brand and model number of the monitor and how is it connected, including any adapter.

3. Use this command to open the “Xorg.0.log” file:

Code: Select all

gedit /var/log/Xorg.0.log

That command is for Mint Cinnamon and Xfce. If using MATE, change gedit to pluma.

Press Ctrl+A to select the entire file contents. Right click on the screen and select “Copy”. Don't save it to a file. Open the Mint Forum reply window and select
“Code” in the menu. Paste the copied lines between the two code words.

If you have problems posting that long file, then upload it to pastebin.com by using this command:

Code: Select all

pastebin /var/log/Xorg.0.log

Post the URL link that displays in the Terminal window.

What Linux distribution are you using? You didn't post all of the information from using the command inxi -Fxz, as requested by Pjotr. This line is from the log file:
[ 28.897] Current Operating System: Linux romi-PC

This warning line shows the Nvidia driver is unable to read the monitor's EDID data. A monitor connected through it's VGA connector is called a CRT:
[ 36.246] (WW) NVIDIA(0): Unable to read EDID for display device CRT-1

After doing a search for the monitor's specifications, it shows DVI-D and VGA connectors. If you use a DVI to DVI connection, then the monitor's EDID may be read correctly.

Otherwise a custom xorg.conf file will need to be created. I'll give the instructions after you reply.

The version of Mint i'm using is 17.2 (Cinnamon) thank you for the reply.

First rename the monitors.xml file in /home/your-user-name/.config (a hidden folder), to monitors.xml.old or the settings in that config file
may conflict with an xorg.conf file settings. Then create an xorg.conf file by using this command in the Terminal:

Code: Select all

gksudo gedit /etc/X11/xorg.conf

In the opened empty file, add these lines:

Code: Select all

Section "Monitor"			
   Identifier    "Monitor0"
   HorizSync       30.0 - 83.0   
   VertRefresh     56.0 - 75.0
EndSection  

Section "Device"
   Identifier   "Device0"
   Driver   "nvidia"   
EndSection

Section "Screen"
   Identifier   "Screen0"
   Device    "Device0"
   Monitor   "Monitor0"
   DefaultDepth   24
   Option "DPI" "89 x 88"
   Option "ModeValidation" "AllowNonEdidModes"
   Option "metamodes" "DVI-I-1: 1440x900_60 +0+0"
EndSection

Reboot. If there is a startup problem and you can't get to the desktop, then at the GRUB boot menu select Recovery Mode. If no menu shows, then hold down the
Shift key while starting, or keep tapping the key. In the menu, select “root - drop to root shell prompt”. When asked for the root password, just type your user password.
Then change the file permissions to read and write by typing:

Code: Select all

mount -o remount,rw /

Then type this command to remove the xorg.conf file:

Code: Select all

rm /etc/X11/xorg.conf

Then type: reboot
You'll go back to the Recovery Mode menu. Don't click anything, just wait about 7 seconds for the reboot.
