[gentoo-user] Desperately seeking modelines; xorg 1.6.3.901-r2 bleeds off the edges

[Kevin O'Gorman]

[-- Attachment #1.1: Type: text/plain, Size: 1192 bytes --]

I normally stay logged in forever, even after updates.  I'm both busy and
lazy.  However, the Xorg flurry seemed to have died down, so I took the
plunge and rebooted.  Oops.

<troll option=ignore>
It had not re-emerged xf86-input-* for me, a case that I think should be
handled automatically -- I use a source distro because I want to be able to
tweak it, not so that it can force me to do so at arbitrary, inconvenient
and unpredictable intervals.
</troll>

That was easily solved by searching my gmail archive, which in my case
contains only the contents of technical mailing lists.  Gmail seemed to me
perfect for that.  Others had already solved that problem, and I re-emerged.

The bigger problem is that now Xorg is trying to display things off the left
and right edges of my monitor.  By adjusting the monitor I see that there
are 24 pixels of stuff bleeding off the edge -- enough to lose a close box,
for instance.

My Xorg.conf does specify some details about the monitor, but no modeline.
I had to put that stuff in there originally to get my preferred 1280x1024
resolution.  Do I need to go back to the days of modlines?  Xorg.conf is
attached.

gentoo is about 'doing it yourself' and 'emancipation of the user' and not 
about 'holding your hand'. It is not gentoo's fault if you act stupid.

Opinions differ about what constitutes stupidity.  I'm not much interested
in yours and I don't speak about mine, in part because neither one clarifies
anything.  Opinions about usefulness are another matter. Why not dispense
with portage and have everyone compile their own from tarballs -- just
publish a list of packages and patches; then you'd really not be holding
hands.  It seems to be a matter of degrees and judgement.

Modifying the monitor section made no noticeable change.  There's still a
24-pixel bleed off the right edge to begin with.  I can fool with settings
to make it bleed left instead, but there's no setting that affects pixel
spacing.  I like the cleaner monitor section, though.

I'm back to thinking about modelines.  Any better ideas?

I'd try adjust the frequencies first, then try modelines.

Safe frequency ranges are in the monitor's documentation. Do you have docs for 
your monitor (I'm using it's a CRT).

You can safely reduce either horiz or vert range. As the electronics[1] age, 
the monitor's ability to correctly sync the start of the picture with the 
start of the display area deteriorates, especially at the upper bound. If 
reducing the upper bound of the horiz setting improves matters, that is 
indicative of this happening.

[1] more specifically, electrolytic capacitors. They are temperature-
sensitive. Silicon does not "wear out" as such.

When I start it up, the left edge is fine, which is the sync edge.  Because
of that and because I can adjust positioning left and right, and because the
problem arose abruptly with the reboot to a new Xorg, I rate the probability
of hardware problems low (but not zero of course).

It appears to be a problem of horizontal spacing of the pixels.  At it
stands there is not room for the last 24.

  What type of monitor do you have?

  How old is it?

  What is the screen size?

  What exactly do you mean by bleeding edges? Does the gui scroll when you move you mouse towards the edges? is that what you mean by bleeding?

  Another thing; Do you have the monitor manual? It will tell you the proper H and V sync rates at certain resolutions. 

  Are you sure it supports that resolution?

It's a couple of years old, I guess.  It's new enough to talk to X and
report:
    (II) MACH64(0): clock: 121.8 MHz   Image Size:  410 x 308 mm
  which agrees with my ruler.  In inches a little over 16" x 12" visible.

The video card is sending all 1280 dot columns.  I have a control on the
monitor called "H position" and I can scroll one pixel at a time to change
which 1256 dot columns I want to see of the 1280 that are sent.  The image
does not scroll with mouse movement.

I have the manual.  You are way over-optimistic about its contents.  I had
no better luck on the web site.  The limits I've posted were acquired by X
from the monitor itself.

The monitor did fine until I rebooted yesterday.  Its on-screen display
shows it thinks it's doing 1280x1024@60Hz.
It's close of course, but not quite there.

        Safe frequency ranges are in the monitor's documentation. Do you have docs for
        your monitor (I'm using it's a CRT).

        You can safely reduce either horiz or vert range. As the electronics[1] age,
        the monitor's ability to correctly sync the start of the picture with the
        start of the display area deteriorates, especially at the upper bound. If
        reducing the upper bound of the horiz setting improves matters, that is
        indicative of this happening.

        [1] more specifically, electrolytic capacitors. They are temperature-
        sensitive. Silicon does not "wear out" as such.

      I have docs.  They are not very informative.

      When I start it up, the left edge is fine, which is the sync edge.  Because of that and because I can adjust positioning left and right, and because the problem arose abruptly with the reboot to a new Xorg, I rate the probability of hardware problems low (but not zero of course).

      It appears to be a problem of horizontal spacing of the pixels.  At it stands there is not room for the last 24.

      What type of monitor do you have?

      How old is it?

      What is the screen size?

      What exactly do you mean by bleeding edges? Does the gui scroll when you move you mouse towards the edges? is that what you mean by bleeding?

      Another thing; Do you have the monitor manual? It will tell you the proper H and V sync rates at certain resolutions. 

      Are you sure it supports that resolution?

  It's as listed in the xorg.conf above: I can be sure because it's Westinghouse.  It's a flat-screen.
  It's a couple of years old, I guess.  It's new enough to talk to X and report:
      (II) MACH64(0): clock: 121.8 MHz   Image Size:  410 x 308 mm
    which agrees with my ruler.  In inches a little over 16" x 12" visible.

  The video card is sending all 1280 dot columns.  I have a control on the monitor called "H position" and I can scroll one pixel at a time to change which 1256 dot columns I want to see of the 1280 that are sent.  The image does not scroll with mouse movement.

  I have the manual.  You are way over-optimistic about its contents.  I had no better luck on the web site.  The limits I've posted were acquired by X from the monitor itself.

  The monitor did fine until I rebooted yesterday.  Its on-screen display shows it thinks it's doing 1280x1024@60Hz.
  It's close of course, but not quite there.

  So It's a flat-screen and not a flat panel lcd monitor? 

  I think I'm beginning to understand your issue... setup the modelines like i told you and then check the monitor on-screen display settings. It seems it's not a modeline issue because modelines are primarily used to adjust frequency. Lower the resolution if you can to avoid the screen from going out of view range.

    I'd try adjust the frequencies first, then try modelines.

  I'd try that too if I had a clue how to do it, let alone do it safely.  Got any pointers to FMs?





  If you have a flat panel it will not mess up your monitor because they have safeguards against that and also modelines don't go in the monitor or screens  section...they go in the modes section...did u try what i mentioned in my last post.

I did not know what to do with your last post, as the modelines were not
acceptable.
The actual rates the monitor is showing now are 54.2KHz and 60.2Hz, which
are well within specs.

I chose the section from memory.  In the pre-Xorg-pre-XFree days I seem to
recall using different modelines at different depths.
Modes section all by itself, not a subsection?  I'll try that.

  If it was a subsection my post would have stated EndSubSection or something similar...Place the modes section after the InputDevice Section. Get your own modes...using gtf and slip them into the modes section like so:

  Section "Modes"
          Identifier      "16:10"
          <you modeline here>
  EndSection

  But remember, you can leave out or specify the identifier ratios depending on whether it will work for you or not.

In that case I'd first try the monitor's own auto-adjust feature.
Usually this is available by pressing some "menu" key on your monitor. 

If that doesn't work then make sure you have DDC support in your driver
and enable it. You monitor is new enough that it should just work after
being queried by DDC.

    gentoo is about 'doing it yourself' and 'emancipation of the user' and not
    about 'holding your hand'. It is not gentoo's fault if you act stupid.

  Opinions differ about what constitutes stupidity.  I'm not much interested in yours and I don't speak about mine, in part because neither one clarifies anything.  Opinions about usefulness are another matter. Why not dispense with portage and have everyone compile their own from tarballs -- just publish a list of packages and patches; then you'd really not be holding hands.  It seems to be a matter of degrees and judgement.

  Modifying the monitor section made no noticeable change.  There's still a 24-pixel bleed off the right edge to begin with.  I can fool with settings to make it bleed left instead, but there's no setting that affects pixel spacing.  I like the cleaner monitor section, though.

  I'm back to thinking about modelines.  Any better ideas?

  Let's not rule-out the possibility that this might be an issue with a bad video card. I once thought I had a bad monitor because of horizontal and vertical bleeding and it turned out to be the video card. Try the modelines, if it does not work, swap video cards.

None of the above are what I want.

On another track, the Xorg log has a bunch of Modelines listed, but I can't
see immediately which one it used.  I'd like to start with that one and
tweak it.  Just the 1280x1024 ones are

(II) MACH64(0): Modeline "1280x1024"x0.0  135.00  1280 1296 1440 1688  1024
1025 1028 1066 +hsync +vsync (80.0 kHz)
(II) MACH64(0): Modeline "1280x1024"x0.0  108.00  1280 1328 1440 1688  1024
1025 1028 1066 +hsync +vsync (64.0 kHz)
(II) MACH64(0): Modeline "1280x1024"x60.0  108.00  1280 1328 1440 1688  1024
1025 1028 1066 +hsync +vsync (64.0 kHz)

I guess I'll try them to see if I can get a known starting point.

Did you try X -configure? Or even without xorg.conf?

I did.  I was forced to by the behavior of X without them.  That whole thing
started out as the results of X -configure.

                  Just use gtf to get your desired modeline.

                # 1024x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 64.11

                Modeline "1024x768_60.00"  64.11  1024 1080 1184 1344  768
769 772 795  -HSync +Vsync
I put them in the Display section of Screen with depth 24.  Comment them out
and all is okay.

Back in the bad old CRT days a tool like xvidtune was the way to find
appropriate mode lines.  I've not needed it since switching to newer
monitors, thankfully, but it's still in portage.  It even prints out
the safe frequency ranges on the command-line if your monitor is new
enough to supply that info.
