editing refresh rate in xorg.conf does nothing

Riallin · 02-19-2005, 11:38 PM

Hey all, running slack 10.1, kernel 2.6.10, and fluxbox

problem is, before i wiped and resinstalled, i had my monitor working perfect. Now, though, even after I edit my xorg.conf file to the exact same thing as before, it chooses refresh rates out of the range I specifically list. I have even tried putting only one number for each, and yet it always pops it into the same 95.3x59 rates.

I have an ati radeon 5(7?)00 or whatever is the one that ati does not support, so I have chosen to use the "radeon" driver in xorg. Then, I have 24 bit resolution, set at 1920x1440 (i have also tried 1600x1200 and 1024x768 which also failed), and the issue I mainly have is that sometimes I would like to plug in my roommates projector to my computer so we can watch my movies (since he has no HD space for my stuff).

Currently, I have my monitor zooming in and then all the settings are maxed out solely to get the screen wide and high enough to not leave 5 inches of space all around

I have a vprMATRIX 1796, which, according to the menu, has a range between 31.4 and 95.3, and also 59 through 86.

Please help!

When you edit xorgconfig, what do you do when it askes for a resolution?
I had that problem to a while ago, but it all I did was to change resoluton for 24 bit. And then I chose option d (1400x10XX) and then, instead of pressing "the modes are Ok" I just pressed enter, that helped me out anyways...
That may seem very noobie but that is what helped me out =)

Riallin · 02-20-2005, 06:17 AM

well, under resolution for 24 I have

"1920x1440" "1600x1200"

and have replaced that with many other options, such as 800x600 and 2034x768 and 1280x1024, all of which did not work.
other than that, there is no option "d" or "modes are Ok" in the xorg.conf file (i edit the file itself, instead of running xorgconfig or whatnot)...

thanks for the idea though, but it doesn't change anything

Are you sure that your X is reading the /etc/X11/xorg.conf file?

I know that in XFree86, sometimes this is a problem when there are two files XF86Config and XF86Config-4.

Just wondering whether there is another file in /etc/X11 which conflicts or overrides the xorg.conf file.

db391 · 02-20-2005, 07:18 AM

Reading Harishankar's post, the exact same thing happens in Xorg.

Reading the xorg.conf(5x) manual page, it states that X reads the files in the following order:

/etc/X11/<cmdline>
/usr/X11R6/etc/X11/<cmdline>
/etc/X11/$XORGCONFIG
/usr/X11R6/etc/X11/$XORGCONFIG
/etc/X11/xorg.conf-4
/etc/X11/xorg.conf
/etc/xorg.conf
/usr/X11R6/etc/X11/xorg.conf.<hostname>
/usr/X11R6/etc/X11/xorg.conf-4
/usr/X11R6/etc/X11/xorg.conf
/usr/X11R6/lib/X11/xorg.conf.<hostname>
/usr/X11R6/lib/X11/xorg.conf-4
/usr/X11R6/lib/X11/xorg.conf

Unfortunately, sometimes xorgconfig/xorgcfg has a bad habit of placing xorg.conf in the home directory like /root/xorg.conf.new - move this file to /etc/X11/xorg.conf and see if X behaves

Get Section "Monitor" right and xwindow would launch at the highest refresh rate your monitor and display card can support at the chosen resolution (which ever is lower).

Code:

Section "Monitor"
#DisplaySize      320   240     # mm
Identifier   "Monitor0"
VendorName   "brandname"
ModelName    "model"
DisplaySize  325   243  #Quite important if you want optimum performance
HorizSync    30-71 #check your manual
VertRefresh  50-160 #check your manual
#Option     "DPMS" #i hate my monitor switching off.
EndSection

Well, checked every directory that was listed by db391, and i only found 3 files, all of which in /etx/X11:

xorg.conf
xorg.conf-fbdev
xorg.conf-vesa

Well, the main thing that bothers me about all this, is that changing the resolution in xorg.conf works, but when i mess with the refresh rate, it goes straight to the worst possible!...

Riallin · 02-20-2005, 03:53 PM

Hey carboncopy, what exactly is the display size? I don't see it anywhere on the vprMATRIX website

Don't worry about a displaysize value for now. It usually will be "self discovered" by the X-server. Can you post the values in your "Monitor" section? Your refresh rate is determined by a combination of the "VertRefresh" and "HorizSync" options. Be sure that the high value on vert is high enough and the low value on the Horiz is low enough. Check your monitor's specs to be sure (before you fry it).

h30 - 96
v50 - 160

as stated on the vprMatrix website.

I don't know which ATI driver you have, but I have
one laptop with an integrated ATI card and it uses
vesa for the driver in /etc/X11/xorg.conf rather than
radeon. Try that, as well as putting your refresh
rates in that file like this:

Code:

<snip, snip>
Section "Monitor"

    Identifier  "My Monitor"

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    HorizSync   30 - 96

#    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.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    VertRefresh 50-160

EndSection

See if that helps. And remember, you can always
save your current xorg.conf as /etc/X11/xorg.conf.old
before you make some changes; and if your changes
don't work, from the prompt you can just issue:

Code:

mv /etc/X11/xorg.conf.old /etc/X11/xorg.conf

and you'll be right back where you're at now...

Riallin · 02-24-2005, 10:18 PM

well, the frustration is about how it all *used* to work, the way that they are currently set at (when i had slack 10.0 installed, before i upgraded to 10.1)

gbonvehi · 02-24-2005, 10:46 PM

Riallin take a deep look at the xorg.conf file, I've the refresh rate stuff in the "Device" section, maybe you've them there too.

There is no specific "Device" section in /etc/X11/xorg.conf
in either Slack-10.0 or Slack-10.1 -- this information by
default, unless you change the file, is in "Monitor section" ...

gbonvehi · 02-24-2005, 11:06 PM

Not a default one sorry, I generated it using X -configure.
This is how it looks like:

Code:

Section "Device" 
        Option     "HorizSync"          	"31.5 - 80.0" # <str>
        Option     "VertRefresh"        	"60-90" # <str>
	Identifier  "Card0"
	Driver      "nvidia"
	VendorName  "nVidia Corporation"
	BoardName   "NV17 [GeForce4 MX 440]"
	BusID       "PCI:1:0:0"
EndSection

Anyway, as it's a card option, maybe it's specific to mine.
