[ SOLVED ] Setting Refresh in Xfce, GUI tool not working.

Hello,
I have a LCD monitor, it needs a refresh of 60Hz ( or so I am told. ) I have tried the Settings->Display GUI tool but no change at desired resolution.
Note : this is with the ( xf86-driver-nouvaeu ) driver. Resolution "1280x1024_60.00" on Salix64, Xfce.
Found a thread in this forum and tried it as well. Not allowed to post a link to it ( yet ).
The error I got for the above thread was "xrandr cannot find output default".
The command "X -configure" errors out in root user / runlevel 3. No preexisting "xorg.conf" to be found.
I did track down the "read-edid" package. It errors out. "ddcprobe" was not found. The Xorg.0.log has some useable Modelines and so does the Windows Monitor "driver".
Sample Data :
Identifier "Monitor0"
VendorName "Proview Electronics Co.,Ltd."
ModelName "PTS06A5"
Modeline "1280x1024" 108.00 1280 1328 1440 1688 1024 1025 1028 1068
Modeline "1024x768" 78.75 1024 1040 1136 1312 768 769 772 800
Modeline "800x600" 36.00 800 824 896 1024 600 601 603 625
Modeline "720x400" 28.32 720 738 846 900 400 412 414 449
Modeline "640x480" 31.50 640 664 704 832 480 489 492 520
Option "DPMS"
I hope that I did this right ....
I am lost at what to do at this point.
Thanks for any help... ( a new Salix64 user )

What's the output of xrandr from a terminal?

Thank you for responding.
The error is the same with or without X running.
The output as requested :
assembler[~]$ gtf 1280 1024 60

assembler[~]$ xrandr --addmode default "1280x1024_60.60"
xrandr: cannot find output "default"
assembler[~]$
It seems that "default" is a required mode name. I tried changing it and same response.

I didn't ask for that. I asked for the output of xrandr. Just like that, no options.

Thanks for responding again.
By no options, I take it as meaning this ...

You're already running at 1280x1024.
BTW, as that shows, your monitor's name is not "default", it's "DVI-I-1"

Thanks for responding.
The first output listed (DVI-I-1) is showing a refresh of 75. That is the output connected to the LCD monitor.
DVI-I-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
1280x1024 75.0 + 59.9*
The LCD's built in menu based adjustment is showing refresh currently at V : 75.0 Hz. And the screen is still flickering.
The other DVI output on the NVIDIA card is not connected to anything.
DVI-I-2 disconnected (normal left inverted right x axis y axis)
1280x1024_60.00 (0x12c) 108.9MHz
I am wondering if "defining" an output or swapping outputs would have an effect ?

Try this:
Code: Select all
xrandr --newmode "1280x1024_60.00" 108.88 1280 1360 1496 1712 1024 1025 1028 1060 -HSync +Vsync
xrandr --addmode DVI-I-1 "1280x1024_60.00"
xrandr --output DVI-I-1 --mode "1280x1024_60.00"
It should work. If it does, you can put those in /etc/gdm/Init/Default, towards the end, before the last exit command.

Thanks again !
The results ...

Found an Xorg xrandr manual page :
http://www.x.org/archive/X11R7.5/doc/ma ... ndr.1.html
and got rid of the outputs under DVI-I-2.
I will take your advice and put this in the gdm init file.
Going to log off and reboot. Testing Time.

FYI ...
The nouveau driver is preventing xrandr from interfacing properly, apparently.
I blacklisted / uninstalled the nouveau driver and installed the SlackBuild NVIDIA 290.10 driver.
The refresh is correct now.
Thank you for your efforts and knowledge.
