Let's try something a little exciting and progressive, even if we are using Slackware.

Backup your /etc/X11/xorg.conf.

As root, run `xorgcfg`.

With a display panel like that, and a reasonably recent video card (AGP you say? Should be good enough) there's a more than moderate chance that X will be able to probe both the card, and the display, and in a few moments you'll likely see a stick-figurish representation of your hardware arrangement and things will "just work".

The best part is that even if it doesn't work, you only blew about 60-90 seconds trying it.

Good luck with evilDagmar's suggestion, I have never tried that.

Does your graphics card have a dvi output, or just vga? dvi is preferable if it is available and might fix the problem.
Also, you may want to investigate the displaysize option in the monitor section of xorg.conf

heres a useful link:

edit:
Ok I worked it out for you :-)
if your monitor's dot pitch is correctly reported as .258 (vert & horiz), then at 1600x1200 I get 412.8 x 309.6
rounded down to the nearest mm gives (1st entry in section "Monitor")

DisplaySize 412 309

Tried 'xorgcf' and go stuck on black screen because I did not know how to navigate the options and selection on the small box. Would I just run probe command in that application?
I had to shutdown the pc and booted into windows to post this question: can u give me a little more direction on using xorgcf?

Tobyl, only vga connector on the back. Thanks

I know when I couldn't get X configured I copied a working version of xorg.conf from Mandrake! The vesa driver didn't work for me. But it might be best if you run xorgsetup again as root, and if it doesn't work, check the error log to see why. It depends how messy your xorg.conf has become. Also, what does 'artifacts' refer to?

simcox1, by artifacts I am referring something that looks like video noise in colors white,black,blue and now its more red... like when you switch your tv channel from cable 3 to none recieving channel...lol One thing about xorgcfg is that it did have the easy option for display size but can you save setting from that application to xorconfig file and how? Going to look at my xorgcongfig file now. My video card only has vga connector. My mobo
is PC100. My just delete xorgconfig file and start over. Already ran xorgsetup but it requires you still config
xorgconfig by hand. Thanks

Looking for the right format xorgconf file... it will stop working and spit out a "Parsing Error" if format doesn't match.

Tried putting writing to monitor section "Display Size" but startx would not accept it
generated "Parsing Error". Do you have a Display Size in your xorgconf file? Getting fed up.. Goto my Help With Cups Thread Now. lol If I can accomplish one thing to recharge my motivation.

I don't seem to need a DisplaySize in my xorg.conf as the monitor reports its dimensions ok, but I tried it anyway, and it worked (athough I used different dimensions as my screen is different to yours).
The syntax is simply

DisplaySize 412 309

no quotes, no space in the word DisplaySize (but note the capitalization)
If that doesn't work, it would be interesting to see the xorg log, if it gets that far...

Tobyl, where exactly did you place your entry? Within Section Monitor? I will try again now. I have been re-reading the X5, Xorg.con-Configuration File and according to that information I should be able to include an 'Auto Option' Allowing the monitor auto feature to run,U think?
Reasoning being this: "(WW) R128(0): Can't determine panel dimensions, and none specified. Disabling programming of FP registers." from /var/log/Xorg.0.log

yes, I put it as the first entry in section Monitor.
I'm not familiar with the Auto option you describe, could you elaborate?


Quote:
"(WW) R128(0): Can't determine panel dimensions, and none specified. Disabling programming of FP registers."
It is this entry in your log that has prompted my suggestions up to now. My reasoning being, if no panel dimensions are determined and none specified, then we should specify them ourselves...

The DisplaySize command is not foolproof, there are many examples if you google, of people complaining that it is ignored, (probably driver dependent), but we can try it. A parsing error as you suggest, is most likely a syntax error. If we get the syntax right, then the log may reveal more...

tobyl, I so appreciate your consistent support, you're a find. Good news, I was able to get xorg.conf file to accept DisplaySize Entry and it shows up in the middle of /var/log/Xorg.0.log but so does the inital warning you quoted above.
The band across top of my monitor is intermittent and not as wide now.
What I mean by Setting an 'Auto Adjust Option' for monitor is that this monitor does not run on software driver, it self adjusts...In windows all I had to do was set the desktop resolution to 1024x768 and refresh
rate to 60Hz before disconnecting the CRT and Pluging this one in. It has an OSD Menu and ABT light reading Sensor so it can auto adjust brightness. So far all worked well so I never do any manual adjusting. Probably will get into that if I can ever switch over and start doing some web graphics.
So I was wondering if there is some way to set xorg.conf to just let monitor do its thing? And yes I noticed "bug posts related to DisplaySize in Xorg", but it is confusing because there are so many hardware and configuration options. I promise to dedicate a plain english site for slackware if I ever get it all working. [Still no printer, paper feed turns on everytime i start and shut off pc ??? Tried installing some package and have no clue what I did.]

Nightsky,

As far as I know there are two ways that X gets its info. If the monitor sends EDID info (ie screen dimensions, timings etc), and the driver can interpret it, then it can be setup automatically. Otherwise, we have to give a bit of extra help in the xorg.conf file.

Your monitor is not sending this information. Whether there is an option in your monitor OSD to change that, I don't know, but I doubt it.

So we have to work out what to tell Xorg to get a good working configuration. Our problem is compounded by the fact that your graphics card is a little on the old side, and the linux driver development for r128 is probably not getting attention anymore.

The options open to you that I can think of are
1.Play around with the DisplaySize settings, maybe reducing the vert size by a small amount

2.Try using a lower resolution. Actually, if a lower res works and fills you screen correctly, run

$ xdpyinfo |grep dimensions

it should give the correct dimensions for your DisplaySize parameter

3. Try temporarily disabling module DRI from xorg.conf (google tells me this worked for another ati rage user) just to see if it makes a difference.

4.Try generating a modeline again (gtf is one way to do this, type at the prompt:

$ gtf 1600 1200 60

5.Try using the slightly scary xvidtune (better read up on it before doing this one, I have never used it)

6.Splash out on a new graphics card (You could get a midrange Nvidia card pretty cheap, and they are much better supported in Linux and you would really be glad you did) AGP cards are still easy enough to find, or you could get one from ebay for a few dollars) or cadge one off a friend who has just upgraded :-)

that little lot should keep you busy - I am sure it can be done, its just a matter of how much time/patience you have

Thanks tobyl, Will try your suggestions. Actually this ATI Rage card is a replacement for a agp nvidia geForce, I did try to get another agp Nvidia Card, got this one through ebay. I just rebuilt a box for my neighbor will check to see their video card. Thing is if I can get this slackware12 to where I need it to be 'the graphics' is not top priority for web/file server and I have a new XP Build. This Slackware Box is dualboot w/win98 I would like to migrate to slackware, but so far Win98 is much faster than slackware12 and stable for my online usage, just downloaded adobe flash player, it installed successfully. I would feel alot more secure with my online functions running in slackware12, I don't want to run XP online unless its through slackware server. Tall order???
Started to use xvidtune but decided against it after its warning about breaking the monitor lol not worth the risk for me.

tobyl, From command line outside of Xfce I tried code:$ xdpyinfo |grep dimensions and got Can not open window /code

Fireded up Xfce, openned terminal code:$xdpyinfor |grep demensions and got back nothing. Tried same code as root with same results./code Maybe a syntax error on my part? Oh, missed you saying to change res and then do the |grep,
have to do that.

Question: Would displaysize belong in Screen Section? This info. was requested for screen section in xorgcf tool if I remember correctly. hmmm

Can I compile kernel although I don't have everthing settup yet,ie. Display and printer?

code:$gtf 1600 1200 60
1600x1200@60.00Hz (GTF) hsync: Modeline 74.52KHz; pclk: 160.96MHz
Modeline "1600x1200_60.00" 160.96 1600 1704 1880 2160 1200 1201 1204 1242 -HSync +VSync
(These numbers look high? My monitor doesn't go above 1600x1200? What do you think? Where do I place the modeline? Will look it up too. Thanks

Nightsky,

If you didn't have X running then xdpyinfo hasn't got anything to look at!

From within X it should work, check your typing...
(I only said to try a lower res as I am not sure if xdpyinfo would give the correct numbers when your fault is in evidence)

DisplaySize goes in section Monitor. Haven't tried it elsewhere.

yes.

Quote:

The big numbers refer to clock timings not pixels

Put the line in section Monitor again (Disable the DisplaySize parameter with a # for now)
All of it just like this:

Section "Monitor"
Modeline "1600x1200_60.00" 160.96 1600 1704 1880 2160 1200 1201 1204 1242 -HSync +VSync

tobyl

edit: oops I forgot something

you should also change the line in section Screen
under your default depth to
Modes "1600x1200_60.00" "1600x1200" "1280x1024" "1024x768"

to tryout the modeline thing.
