Error adding xrandr mode

Question

I am following the following xrandr documentation on adding a missing resolution, and am getting an error that I can't resolve.

user@box:~$ cvt 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

Then it says to use --newmode to create the mode

user@box:~$ xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync

and finally add the mode to the output. This is where I get the error, and I can not figure out what exactly is going on. Nothing I found online could resolve this issue.

user@box:~$ xrandr --addmode DVI-D-0 "1920x1080_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

PLEASE HELP!! I am so sad and desperate! :P

EDIT: Here is some additional very important revelations.

There is some docs on my exact error....

https://wiki.archlinux.org/index.php/NVIDIA/Troubleshooting#xrandr_BadMatch

And I have confirmed in xorg logs that I have a bad EDID....

[ 27.493] (WW) NVIDIA(0): DFP-0 does not have an EDID, or its EDID does not contain a [ 27.493] (WW) NVIDIA(0): maximum image size; cannot compute DPI from DFP-0's EDID.

Solution

It looks like your problem is, you might not have anything connected to the port you are trying to send the xrandr command to. I tested some on my system here and received the same error. Make sure that you are running the command on the correct port. I will use an older monitor of mine as a demonstration.

terrance@terrance-ubuntu:~$ cvt 1280 1024
# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz
Modeline "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync

terrance@terrance-ubuntu:~$ xrandr --newmode "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync

terrance@terrance-ubuntu:~$ xrandr --addmode DVI-I-0 1280x1024_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

Here's the error. The next line shows me all my connected DVI ports.

terrance@terrance-ubuntu:~$ xrandr | grep -w connected
DVI-I-1 connected 1024x768+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm
DVI-I-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 509mm x 286mm

As we can see, mine that I want is connected to DVI-I-1, so I corrected the line to match my connected monitor.

terrance@terrance-ubuntu:~$ xrandr --addmode DVI-I-1 1280x1024_60.00

terrance@terrance-ubuntu:~$ xrandr --output DVI-I-1 --mode 1280x1024_60.00

terrance@terrance-ubuntu:~$ xrandr | grep -w connected
DVI-I-1 connected 1280x1024+1920+0 (normal left inverted right x axis y axis) 0mm x 0mm
DVI-I-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 509mm x 286mm

And now, my monitor took the new mode and looks good.

Hope this helps!

The line xrandr --addmode DVI-D-0 "1920x1080_60.00" should be xrandr --addmode DVI-D-0 1920x1080_60.00

[Scorb]

No it doesn't. Either way, it results in the same error.

[George Udosen]

Please can I have the link to the steps you followed ?

[Scorb]

sorry I forgot to add it.

[George Udosen]

I have seen your link and your have "1920x1080_60.00" when you should have 1920x1080_60.00 like I had pointed out. The error is in the parameters your passing to xrandr

[JosephK]

I agree the error is in the parameters passed, but adding or removing quotes to either or both of the parameters has no effect - the same error message results with all possible combinations of quoting either/all/or those two params.

[Scorb]

If i run xrandr -q it only lists DVI-D-0 and HDMI-0. My card only has 1 DVI-D out, so I am certain DVI-D-0 is correct. Thank you for your response!

@ScottF What does xrandr | grep -w connected return?

[JosephK]

I copied and pasted exactly what is shown in "connected" as well as the name I used for "newmode" line, and I still get the same error.

[Terrance]

@JosephK What Ubuntu version are you running?

[JosephK]

The problem turned out to be that the NVIDIA driver no longer supports xrandr beyond query-mode. You have to specifically allow settings not found in monitor-detection, add that flag plus settings, etc.
