[Solved] Can't set resolution

Hi there. My GPU is GTX650, my native resolution is 1280x1024, but I can't set it.

[duckerman@duck ~]$ 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:  35
  Current serial number in output stream:  36

I use DVI-to-VGA adapter

Solution:

Add custom EDID file

Re: [Solved] Can't set resolution

Did you create a valid modeline for it?

Yep, I've tried 

sudo xrandr --newmode "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync

Re: [Solved] Can't set resolution

a) wrong use of sudo
b) Post the output of "xrandr -q" and your xorg log, please.

Re: [Solved] Can't set resolution

drm.edid_firmware=edid/1280x1024.bin

What is that file?

[    26.052] (==) Using config directory: "/etc/X11/xorg.conf.d"
[    26.052] (==) Using system config directory "/usr/share/X11/xorg.conf.d"

[    26.285] (**) |-->Input Device "Keyboard0"
[    26.286] (**) |-->Input Device "Mouse0"

You somewhere have an xorg.conf written by nvidia-xconfig (or the settings gui), please post that.

[    28.112] (**) NVIDIA(0): Option "ConnectedMonitor" "DVI-I-0"

[    29.598] (II) NVIDIA(0): Virtual screen size determined to be 1024 x 768
[    29.609] (WW) NVIDIA(0): CRT-0 does not have an EDID, or its EDID does not contain a
[    29.609] (WW) NVIDIA(0):     maximum image size; cannot compute DPI from CRT-0's EDID.

What brings us to the core of the problem.
What monitor (vendor/model) is that?
If you have a proper EDID file for it, you can make use of

Option "CustomEDID" "string"

Otherwise use the "AllowNonEdidModes" or "ModeValidation" options, see /usr/share/doc/nvidia/README

Re: [Solved] Can't set resolution

It's default EDID, I guess (I've already deleted it)

My xorg.conf is:

[duckerman@duck ~]$ cat /etc/X11/xorg.conf.d/20-nvidia.conf

Re: [Solved] Can't set resolution

# generated from default

Yeah, it's a bunch of pointless cruft

I dont know where to get EDID file

https://github.com/linuxhw/EDID
https://github.com/linuxhw/EDID/tree/ma … er/ACR0019

I'm not sure whether there are meaningful differences in the variants.

Try sth. like this

Section "Device"
    Identifier "Default nvidia Device"
    Driver	"nvidia"
    Option	"NoLogo"				"True" # not strictly necessary ;-)
    Option       "CustomEDID" "CRT-0:/path/to/edid1.bin"
EndSection

The binary edid is the hex block on the top, you can use an hexeditor or https://aur.archlinux.org/packages/hex2bin/ to generate the binary file.

Re: [Solved] Can't set resolution

I thinks it's wrong location, it must be https://github.com/linuxhw/EDID/tree/ma … er/ACR0023

So how can I make `.bin` file?

Re: [Solved] Can't set resolution

And why do you think that?
The first link has

Acer	ACR0019	V173	1280x1024	340x270mm	17.1	2011	0941B

If your txt looks like

00 ff ff ff ff ff ff 00 04 72 19 00 08 ca 7d 83
25 12 01 03 08 22 1b 78 ea dc 55 a3 59 48 9e 24

00 56 31 37 33 0a 20 20 20 20 20 20 20 20 00 79

Use "hex2bin -l 47 …" - and please stop abusing sudo. Sudo is not a "make it work" fix.

So, I add what you said and..
It works, thanks! If I change any settings in nvidia-settings, will I have to add EDID again?

Re: [Solved] Can't set resolution

Only if you use it to over/write an xorg config - what your should not do in general (because it creates a static server layout full of cruft)

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
