sudo displayconfig-gtk in Karmic???

edit:
The Wiki X/Config/Resolution page I think has at least one error, and perhaps another.

One error is solved at post #10. It applies only to 'per-session' fix. I am still working on making the fix permanent, since one of the 3 'fixes' on the Wiki page works only in part...

------------------------------------------------

Alright - start from scratch again here, noted so I can reverse failed steps...

Existing modes:

chuckhtpc@chuckhtpc-desktop:~$ xrandr
Screen 0: minimum 320 x 200, current 1360 x 768, maximum 1360 x 1360
VGA-0 connected 1360x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm

1024x768 60.0
800x600 60.3
640x480 59.9
chuckhtpc@chuckhtpc-desktop:~$

Then check for ability to change modes and back - good:
(obviously 'VGA-0' is the correct name...)

chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 --mode 640x480
chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 --mode 1360x768
chuckhtpc@chuckhtpc-desktop:~$

Now CREATE and ADD undetected resolution:

Create 'ModeLine with cvt utility:
chuckhtpc@chuckhtpc-desktop:~$ 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
chuckhtpc@chuckhtpc-desktop:~$

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

Addmode
syntax = --addmode <output> <name>
chuckhtpc@chuckhtpc-desktop:~$ xrandr --addmode VGA-0 ???
What is the name for addmode syntax?
"1280x1024" ?
"1280x1024_60" ?
"1280x1024_60.00" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync?

With or withOUT parenthesis???


Taking a look at modelines now, BEFORE doing 'addmode', shows THIS??? :confused:

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

Should another parameter been added to 'newmode'???



edit:
I just looked at
http://www.myokyawhtun.com/ubuntu-linux/how-to-change-custom-resolution-in-ubuntu-10.html
and, although he denotes the <NAME> in addmode, his <output> syntax is different:
(one dash before 'addmode', and no dash in VGA-x
xrandr ––addmode VGA1 “1680x1050_60.00″

[ankspo71]

Hi, I have tried doing this myself to see if it can be done, about 10 times already. I tried different sizes and refresh rates and none of them could be activated. They were all reasonable sizes too.

This type of result is given when we use an underscore in the mode name:
1280x1024_60.00 (0x129) 109.0MHz
h: width 1280 start 1368 end 1496 total 1712 skew 0 clock 63.7KHz
v: height 1024 start 1027 end 1034 total 1063 clock 59.9Hz

As far as I can tell, the name requires quotes around it, but does not require an underscore.

I'm going to try recreating an existing working mode. I will try using the same size and refresh rate, except give it a different mode name to see if it works. I will try it with both specifications from gtf and cvt too. I'll be back to let you know if this works or not.

Hi,
This link talks about getting modelines from xorg logs and from a Windows program called PowerStrip (which would be good if you dual-boot Windows and Linux). http://www.x.org/wiki/FAQVideoModes

[ankspo71]

According to 'man xrandr' in the terminal (of Ubuntu 10.10):


EXAMPLES:

Forces to use a 1024x768 mode on an output called VGA:
xrandr --newmode "1024x768" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
xrandr --addmode VGA 1024x768
xrandr --output VGA --mode 1024x768

I notice there are no quotes in the --addmode and --output lines, and the --newmode line is different too... it doesn't have the refresh rate - the one that was in the modeline name.

Here I go again: I already have a mode called 1600x900 so I will call it 1600x900-test*. My output is simply called default, and the output name works with pre-existing modes.

james@Kubuntu:~$ cvt 1600 900 51
# 1600x900 50.92 Hz (CVT) hsync: 47.35 kHz; pclk: 99.25 MHz
Modeline "1600x900_51.00" 99.25 1600 1688 1848 2096 900 903 908 930 -hsync +vsync

xrandr --newmode "1600x900-test2" 99.25 1600 1688 1848 2096 900 903 908 930 -hsync +vsync
xrandr --addmode default 1600x900-test2
xrandr --output default --mode 1600x900-test2

Nope: the new mode I created wouldn't apply:
james@Kubuntu:~$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 240, current 1600 x 900, maximum 1600 x 900

1152x864 55.0 56.0 57.0 58.0
1024x768 59.0 60.0 61.0
960x600 62.0
960x540 63.0
840x525 64.0 65.0 66.0 67.0

720x450 73.0
700x525 74.0 75.0
680x384 76.0 77.0
640x480 78.0 79.0 80.0 81.0 82.0
512x384 83.0 84.0
400x300 85.0
320x240 86.0 87.0
1600x900-test 47.9
1600x900-test2 50.9

I also tried recreating the working existing modes, but they didn't work either.
Nvidia Settings can properly detect my monitor in Ubuntu, but it is not detected in Ubuntu's own display settings tool. In Kubuntu it only says "default", in Ubuntu it says "unknown" (I think), but they both give me a generic set of working display modes to choose from.

[Moozillaaa]

You apparently are having identical problems, except for the one error -
xrandr: Failed to get size of gamma for output default So your syntax is good, but perhaps a parameter call is unanswered (or undefined, with no default).

There seems to be compatibility errors SOMEwhere ( I believe they involve compatibility with the distribution ), rather than end-user errors. I'm in Karmic.

AFTER you did '--newmode', and BEFORE you did '--addmode', did you check to see if it appeared in xrandr return?

Note that I did do this, and the '--newmode' appeared in my HDMI modelist, NOT the VGA-0 modelist. This seems to indicate perhaps another parameter is necessary in the '--newmode' codestring. ???

If (since) the '--newmode' appears in xrandr return, BEFORE '--addmode' is executed, what's the purpose of '--addmode'???

I do dual boot, but have not tried to get data from the XP partition...

Your 1600x900-test mode didn't work... Does X need to be re-started?

Your re-created WORKING mode did not work (when called by re-created NAME, right)? Again, does X need to be re-started?

And yesterday, when I tried to '--delmode' (delete the mode that didn't work), why was 'mode not found'??? This was after '--newmode', and '--addmode' were executed.......

???????

I've tried nothing past post 1 above; will re-try tomorrow here...

[ankspo71]

Hi,
Yes, I just checked to see if my custom mode is listed in xrandr after using the first command with --newmode (and it shows it is listed), but if I try to test it without using --addmode, I get a result saying this:


james@Kubuntu:~$ xrandr --output default --mode 1600x900-test5
xrandr: cannot find mode 1600x900-test5


It seems we need to use the --addmode after using --newmode. I think --newmode creates it and allows it to be viewed in xrandr, and --addmode adds it physically.


I have already tried rebooting after creating the custom modes, but the custom modes ends up getting removed automatically from the xrandr list each time I reboot like shown below.


james@Kubuntu:~$ xrandr --output default --mode 1600x900-test5
xrandr: cannot find mode 1600x900-test5

And here it shows it is gone:

james@Kubuntu:~$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 240, current 1600 x 900, maximum 1600 x 900

512x384 83.0 84.0
400x300 85.0
320x240 86.0 87.0

I'm not sure where to go from here.

[ankspo71]

Hi,
I just found the out the --addmode command we use in the terminal is only temporary for testing purposes, so those custom modes will automatically be lost on reboot. Permanent changes can can be made in /etc/gdm/Init/Default by pasting the same commands in there as shown in the following link: http://www.ubuntugeek.com/how-change-display-resolution-settings-using-xrandr.html , and the original source article here: http://ubuntuforums.org/showthread.php?p=8595940

Have you noticed that cvt and gtf give different modeline values?


$ gtf 1600 900 50
# 1600x900 @ 50.00 Hz (GTF) hsync: 46.30 kHz; pclk: 97.04 MHz

$ cvt 1600 900 50
# 1600x900 49.94 Hz (CVT 1.44M9) hsync: 46.39 kHz; pclk: 96.50 MHz

[Moozillaaa]

You had this return once:

james@Kubuntu:~$ xrandr
xrandr: Failed to get size of gamma for output defaultFrom xrandr usage:
--output <output>
--...
--...
--...
--gamma <r>:<g>:<b>
Mean anything to you? Was yours asking for YOUR input? Or was your system supposed to supply the info?

-------------

Yep - after re-boot, the new / added modes should be gone. I now remember that the wiki page that you linked to said the modification was session-specific, and needed to be made permanent.

But we can't seem to get to that point.....
--------------
So today I booted up, and got reduced resolution. The display GUI showed resolution set at 1360x768. xrandr in the CLI said different; 640x480 - see screenpic.
(the Sony is a 32", and is the secondary output...)

http://ubuntuforums.org/attachment.php?attachmentid=172942&d=1287598535

In the GUI, I clicked the resolution drop-down, not actually changing it, but keeping it on 1360x768, and 'Applied Settings'. It stayed at 640x480.

So xrandr takes precedence over the display GUI, and cannot be changed using GUI? That's not right...
--------------------
So I'm gonna' try some things sort of like you did here:

Re-designate an existing mode:
(Modeline from cvt utility)
chuckhtpc@chuckhtpc-desktop:~$ cvt 1024 768
# 1024x768 59.92 Hz (CVT 0.79M3) hsync: 47.82 kHz; pclk: 63.50 MHz
Modeline "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
chuckhtpc@chuckhtpc-desktop:~$ xrandr --newmode "1024x768_60.00" 63.50 1024 1072 1176 1328 768 771 775 798 -hsync +vsync
chuckhtpc@chuckhtpc-desktop:~$

See how it now shows up, before '--addmode':
chuckhtpc@chuckhtpc-desktop:~$ xrandr
Screen 0: minimum 320 x 200, current 1360 x 768, maximum 1360 x 1360

1024x768 60.0

v: height 768 start 771 end 775 total 798 clock 59.9Hz
chuckhtpc@chuckhtpc-desktop:~$

Try to call it up BEFORE '--addmode', by different names, just to see if anything happens:

chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 --mode 1024x768_60.00
xrandr: cannot find mode 1024x768_60.00
chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 --mode 1024x768 60.00 (removed underscore)
usage: (usage syntax)
...
...
...
chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 --mode (0x129) from '--newmode' entry in xrandr return; see above
bash: syntax error near unexpected token `('
chuckhtpc@chuckhtpc-desktop:~$


Ok - now do --addmode
--addmode <output> <name>
chuckhtpc@chuckhtpc-desktop:~$ xrandr --addmode VGA-0 1024x768_60.00 (0x129)
bash: syntax error near unexpected token `('
chuckhtpc@chuckhtpc-desktop:~$ xrandr --addmode VGA-0 1024x768_60.00
chuckhtpc@chuckhtpc-desktop:~$

Now see what shows in xrandr return, since it's 'added'...

chuckhtpc@chuckhtpc-desktop:~$ xrandr
Screen 0: minimum 320 x 200, current 1360 x 768, maximum 1360 x 1360
VGA-0 connected 1360x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1360x768 59.8*
1152x864 60.0
1024x768 60.0
800x600 60.3
640x480 59.9
1024x768_60.00 59.9
HDMI-0 connected 1360x768+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm
1360x768 60.0*+
1280x720 60.0
1024x768 60.0
800x600 60.3
640x480 59.9
chuckhtpc@chuckhtpc-desktop:~$

It HAS added into the VGA-0 modes section

[Moozillaaa]

Now try to pull it up by the CREATED output name:

chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 1024x768_60.00
usage: xrandr [options]
...
...
...
chuckhtpc@chuckhtpc-desktop:~$

Obviously it does not like the 'created' name. And there's no other way to test for the '--added' mode, since it already exists by it's own name.

So we can only try again with the undetected resolution, which we've already tried...

[Moozillaaa]

We have some progress to report:

From the cvt utility, which gives the 'Modeline' info, is deleted the screen refresh rate:
800x600_60


chuckhtpc@chuckhtpc-desktop:~$ cvt 1280 1024
# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz

chuckhtpc@chuckhtpc-desktop:~$ xrandr --newmode "1280x1024" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync
chuckhtpc@chuckhtpc-desktop:~$ xrandr --addmode VGA-0 1280x1024
chuckhtpc@chuckhtpc-desktop:~$ ^C
chuckhtpc@chuckhtpc-desktop:~$ xrandr --output VGA-0 --mode 1280x1024
chuckhtpc@chuckhtpc-desktop:~$

After the '--addmode' command, I was not returned to a prompt. I waited for a minute, then terminated the process <Ctrl + C> and the I was returned to the prompt, and the ^C text appeared at the prompt simultaneously. I don't know what this was about at all.

Now to make it permanent...
(still need help on this)

I then changed the output for VGA-0, and it changed the resolution as desired!!!

[ankspo71]

Hi,
I think I just stumbled onto something. I trashed my display in Kubuntu today, and I had a copy of PClinuxOS 2010.7 laying around, so I decided to boot into that. I couldn't add my own custom modes here either, and it seems to be worse because each mode I create cant be found when I try to apply it with xrandr.

But, I looked at the /etc/X11/xorg.conf file, and it has information we might be able to use including some modelines. We might be able to use parts of (or the entire) xorg.conf too. The xrog.conf I was using in Ubuntu barely had anything in it, and it didn't have any modelines.

Here the xorg.conf says "modeline generated by gtf(1) [handled by XFdrake]". The thing I don't know about them is...I don't know if these modelines will work, or if they are currently in use.

So if you have a copy of PClinuxOS 2010 laying around (or maybe another distribution not based on Ubuntu), boot into it and run the command:
cat /etc/X11/xorg.conf

In the live cd of pclinuxos, with the non-free Nvidia 195.36.71 graphics driver installed and working, cat /etc/X11/xorg.conf shows this:

Good luck with that. I have to reinstall Kubuntu before I can try it, which will be later today.


From xrandr usage:
--output <output>
--...
--...
--...
--gamma <r>:<g>:<b>
Mean anything to you? Was yours asking for YOUR input? Or was your system supposed to supply the info?

No, mine just kept metioning 'failed to get gamma' (or something like that). It didn't ask me for any gamma values, or any other additional input. This is a 20" widescreen LCD monitor, with a max resolution of 1600x900. It works great with the non-free drivers, but my eyesight doesn't work as good though, so I was hoping for more display options.

Hope this helps.

I think it's solved; see post 10.

I just sent a message to the Wiki/Launchpad pagemasters...


I wasted my display too, and copied my X11 folder in its entirety from a Karmic install on my laptop. I have PCLOS '07, but never boot it up. It wouldn't do Broadcom wireless. Aside from that, it was the fastest distro I ever used, by far...

Time to get bold, and create a startup script.

First, the new/added mode has to be made the default (preferred) selection;
This is done with '--auto'? '--preferred'? Help?

(be back on it later here)

[Moozillaaa]

I got the xrandr script added to the gdm startup file,


#!/bin/sh
# Stolen from the debian kdm setup, aren't I sneaky
# Plus a lot of fun stuff added
# -George

PATH="/usr/bin:$PATH"
OLD_IFS=$IFS

if [ -x '/usr/bin/xsplash' ];
then
/usr/bin/xsplash --gdm-session --daemon
fi

xrandr --newmode "1280x1024" 109.00 1280 1368 1496 1712 1024 1027 1034 1063 -hsync +vsync

xrandr --addmode VGA-0 1280x1024

xrandr --output VGA-0 --mode 1280x1024

initctl -q emit login-session-start DISPLAY_MANAGER=gdm

gdmwhich () {
COMMAND="$1"
OUTPUT=
IFS=:
for dir in $PATH
do
if test -x "$dir/$COMMAND" ; then
if test "x$OUTPUT" = "x" ; then
OUTPUT="$dir/$COMMAND"
fi
fi
done
IFS=$OLD_IFS
echo "$OUTPUT"
}

(rest of file edited for length)

and rebooted.

It came up with the login screen at 1280 x 1024 (I'm pretty sure), but the desktop was at 640 x 480 (note the asterisk):


chuckhtpc@chuckhtpc-desktop:~$ xrandr
Screen 0: minimum 320 x 200, current 1360 x 768, maximum 1360 x 1360
VGA-0 connected 640x480+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1360x768 59.8
1152x864 60.0
1024x768 60.0
800x600 60.3
640x480 59.9*
1280x1024 59.9
HDMI-0 connected 1360x768+0+0 (normal left inverted right x axis y axis) 1600mm x 900mm
1360x768 60.0*+

1024x768 60.0
800x600 60.3
640x480 59.9
chuckhtpc@chuckhtpc-desktop:~$

I think one of the command lines needs either '--auto', or '--preferred' added to the textline, for the default...

Anybody?

[Moozillaaa]

I don't know if anybody is following this or not, and so far I've found one syntax error on the Wiki page here (https://wiki.ubuntu.com/X/Config/Resolution), and the second part of the page, which shows how to make adjustments permanent, is working only in part. I have not found the solution to that error yet.

The 'newmode' of resolution seems to be made permanent by addition of the xrandr commands to the file /etc/gdm/Init/Default, but only the login screen resolution takes the preferred setting. The desktop, in my case, opens at the lowest resolution, until I re-execute the xrandr command to change the mode.

xrandr: cannot find mode 1024×768

I see a lot of people are having trouble with this.

In Linux capitalization is VERY important. Here you guys did not capitalize your the "X" in your resolution. Once you capitalize your "X" you should be good. Here is an example of what worked for me.


xrandr --output VGA1 --mode 1024x768 --rate 60
