dual monitor problem

[Sietse]

Dear users,

Today i have installed ubuntu 12.04 on my office computer. I have 2x iiyama b2403ws (res:1920x1200) monitor. When i boot it sees one monitor as an iiyama like it should, but the other monitor show up like an old crt monitor with a max resolution of 800x600.

XrandR output:

DVI-I-0 disconnected primary (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 519mm x 324mm

DVI-I-3 connected 800x600+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm

Can someone explain to me what i can do about this?

Sincerely,

Have you tried installing arandr and tweaking with it in a GUI? It's in the repositories. Fairly flexible and can fix some things.

[Sietse]

i have tried it with xrandr but i wouldnt let me get a new mode into the DVI-I-3 it would give an error message. What is the difference between xrandr and arandr?

[Sietse]

when i try to run arandr it gives me an error message

Traceback (most recent call last):
  File "/usr/bin/arandr", line 25, in <module>
    main()
  File "/usr/lib/pymodules/python2.7/screenlayout/gui.py", line 302, in main

Exception("XRandR 1.2/1.3 required.")
Exception: XRandR 1.2/1.3 required.

Odd. What version of xrandr have you?

[Sietse]

xrandr program version       1.4.0
Server reports RandR version 1.4

Als nvidia-settings doesnt save anything if i try to change some settings.

[Sietse]

Also when i try to add the mode manually with xrandr i get this:

 xrandr --addmode DVI-I-3 "1920x1200_60.00"
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  33
  Current serial number in output stream:  34

Thread moved to Multimedia & Video.

You might get more help here. Well, at least we know why arandr isn't launching.

As for nvidia-settings, have you tried launching it from a terminal with:

gksudo nvidia-settings

[Sietse]

yes, and as soon as i click apply the program closed with this error:

The program 'nvidia-settings' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadValue (integer parameter out of range for operation)'.
  (Details: serial 1016 error_code 2 request_code 155 minor_code 25)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

[Sietse]

is there someway i can force the EDID of the correctly recognized monitor to apply on the 'not recognized' monitor? Since they are exactly the same?
