Slackware and Xfce - how do you add more resolutions and refresh rates to the menu?
I don't think this is a Slackware-specific question, so I'm using the Newbie forum.
In the menu for display settings I get:

Very strange refresh rates, low resolutions.
In xorg.conf I have:

#  DefaultDepth 8
#  DefaultDepth 16
  DefaultDepth 24
#  DefaultDepth 32


    Subsection "Display"
        Depth      8
        Modes "1024x768" "800x600" "640x480"
    Subsection "Display"
        Depth      16
        Modes "1024x768" "800x600" "640x480"
    Subsection "Display"
        Depth      24
        Modes "1280x1024" "1024x768" "800x600" "640x480"
    Subsection "Display"
        Depth      32
        Modes "1024x768" "800x600" "640x480"

The 1280x1024 under Depth 24 I added myself, since it's default.


    HorizSync  31.5 - 50.0

#    HorizSync        30-64        # multisync
#    HorizSync        31.5, 35.2    # multiple fixed sync frequencies
#    HorizSync        15-25, 30-50  # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.

    VertRefresh 40-90


Normally, when everything's configured for me, I can use 60 and 75 Hz for the refresh rate, and the resolutions up to 1280x1024.

You wouldn't happen to be using an Nvidia/ATI graphics card, would you? Or is it some generic onboard brand?

I have Intel 82915G/GV/910GL Express Chipset Family.
I just changed the horizontal sync and vertical refresh to what it lists in the manual for my monitor, and it gives me 1280x1024@ ~75 from the looks of it by default.

! EDIT !
1280x1024, not 1024x768

I don't want to ruin my monitor. :cry:

joeBuffer 08-03-2009 10:34 AM

It doesn't say what the default setting is, I can just tell that it is.
I can't get a full list of options.

joeBuffer 08-03-2009 10:51 AM

Why does this happen sometimes, that the refresh rates are odd numbers, and you can't get a full list of the normal refresh rates and resolutions?
What happens when a distribution during installation automatically configures everything so that you have exactly the right choices and exactly the right refresh rates and resolutions to choose from? How is it figured out and set up?

joeBuffer 08-03-2009 12:15 PM

Any help at all would be appreciated ... I've changed xorg.conf around a little, and it isn't helping (I've done this before). I would really like to get a list of resolutions and refresh rates onto the Xfce Display Preferences if possible, if there isn't a way to automatically configure this, I would like to know how to configure things so that you can pick and choose what your options are and add them to the list, if you understand what I'm saying.
Also, are there configuration files that affect Xfce other than xorg.conf?

joeBuffer 08-03-2009 01:09 PM

Now, in my Xfce Display Preferences, I have:


since I changed my horizontal sync and vertical refresh to what the manual for my monitor says and added 1280x1024.

joeBuffer 08-03-2009 01:14 PM


bash-3.1$ xrandr
Screen 0: minimum 640 x 480, current 1280 x 1024, maximum 1280 x 1024
default connected 1280x1024+0+0 0mm x 0mm
  1280x1024      76.0*
  1024x768      76.0 
  800x600        73.0 
  640x480        73.0

Can having it at 76 when it should be 75 cause any damage of any kind, even long-term?
Or 73?
I realize I can Google, but I've read the threads on this here, and it seems to me like it would also be a good idea if this was answered with a very quality answer, so if people Google or search this site, there would also be good information on this.

Where did you get your 'xorg.conf'? You modified a sample or run the config utility?

What about 'xvidtune';


excerpt from 'man xvidtune';

xvidtune - video mode tuner for Xorg

xvidtune [ -show | -prev | -next | -unlock ] [ -toolkitoption ... ]

Xvidtune is a client interface to the X server video mode extension

When given one of the non-toolkit options, xvidtune provides a command
line interface to either switch the video mode.

Without any options (or with only toolkit options) it presents the user
with various buttons and sliders that can be used to interactively
adjust existing video modes. It will also print the settings in a for-
mat suitable for inclusion in an xorg.conf file.

Normally the Xorg X servers only allow changes to be made with the
XFree86-VidModeExtension from clients connected via a local connection

Note: The original mode settings can be restored by pressing the `R' key, and this can be used to restore a stable screen in situations
where the screen becomes unreadable.

The available buttons are:

Adjust the video mode so that the display will be moved in
the appropriate direction.

Adjust the video mode so that the display size is altered

Quit Exit the program.

Apply Adjust the current video mode to match the selected settings.

read the rest of the 'man xvidtune'

I usually don't reply to a thread that has been 'PM' to me. I noticed your post but didn't get back to it. You should search here on LQ as this very subject has been covered so many times. :)

joeBuffer 08-04-2009 02:18 PM

I looked around on here and couldn't find an answer ... for some reason I didn't realize you posted this until just a second ago ... I was just about to post how I fixed it.
I read for a few minutes and found things referring to the xorgsetup program. :doh: It works perfectly to get the right resolutions and refresh rates for me. :D
I think I'm gonna like Slackware, it seems very high quality from what I've read about it.

You should mark your post as [solved]. You as the OP can use the 'Thread tools' to mark.

joeBuffer 08-04-2009 04:45 PM

Thanks, I didn't think of it.
