[gentoo-user] Display displacement

[gentoo-user] Display displacement

[Daniel Pielmeier]

Hello,

i solved my problems concering the nvidia-driver and the splash-theme delay.

Nvidia-driver works after upgrading to 1.0.8178-r3 and the splash-theme
starts immediately after the boot message as i updated my kernel to
2.6.15.gentoo-r4.

But one problem still remains, the display is displaced to the left in
all my console windows on boot up, after i logged into my gnome-session
the display fits perfect. When i use the button for automatically
configuring the monitor on boot up, the console windows are looking
fine, but when i log into gnome the display is displaced in the other
direction.

What can i do to fix this problem.

Thank you in advance,

Daniel

There may be another way, but this is how I know to fix it:

First, you should use the "auto" button to fix your consoles.  That's
the easiest.

Then, log into X (with your display now shifted off screen), and run the
command xvidtune.

Read the warning (I've never had a problem).

Then use the "left" and "right" buttons to align the picture exactly
(take note of every pixel!).

Once you're happy, press "show" a few times, then quit.

Now it gets tricky!  You have to edit /etc/X11/xorg.conf.  Search for
the word "modeline".  If it's there already, then you probably have it
easy: just take the output from "show" and put it in place of the
modeline in xorg.conf (commenting out the original).

Eg., xvidtune shows me:
"1680x1050"   119.25   1680 1728 1760 1840   1050 1052 1058 1080

Now, in xorg.conf, I have the modeline:

Section "Monitor"
	...
	...
	Modeline "1680x1050"   119.25   1680 1728 1760 1840   1050 1052 1058 1080
EndSection


You must put it in the "monitor" section that you're actually using -
first look at

Section "ServerLayout"

and find the Screen name (eg Identifier "Screen0"). Then find the
monitor identifier: (Monitor     "Monitor0").  Now look for the monitor
Section with Identifier "Monitor0", and you've found where to put your
modeline!

The names in "" could be different for you, for example, you might have
Identifier "Screen1"
Monitor "17inLCD"
or whatever.

HTH, if you need more info, just post back!

Hi,

@Ian
Xvidtune doesn't work for me, it is not only the displacement in all
directions (mainly horizontally), additionally the picture is not sharp
in some places.

@All
Isn't there another solution out there, i have updated my kernel many
times before and it always works, i think there must be a problem with
the new kernel. I don't think it is the nvidia driver because i have the
displacement with v1.0-8178 and the old v1.0-6629.

thank you

hmm, strange.

Is it the nvidia driver or the framebuffer that's different I wonder?

Do you have any working kernels/nvidia driver's still installed?  Boot
to one of them, reset your monitor, then boot to the current
configuration (without resetting the monitor).  Then see if its the
framebuffer in the new kernel that is out of whack, or the new nvidia
driver that is different.

In either case, someone else with more knowledge about such things will
have to help!

Re: [gentoo-user] Display displacement

[Daniel Pielmeier]

Thank you,

@Ian
i have the old 2.6.14-r5 kernel  with nvidia 1.0-6629 in /boot and in
grub.conf, this configuration works.

But i don' think it is necessary to check this out, because as i
mentioned before, i have the displacement with the old and the new
nvidia-driver. So i think it is a framebuffer-problem. The only thing
i can check is the new nvidia-driver with the old kernel, because the
new kernel does not work with the old nvdia-driver, as you can see
below.

@All
For the better understanding i will post the hole story together.

I updated to kernel 2.6.15-r1, which results in the display
displacement, splash-theme starting up late and nvidia-driver not
working at all.

According to the recommendations of this list i upgraded to kernel
2.6.15-r4 and nvidia 1.0-8178, it solved the splash and the nvidia
problem, but the display displacement still remains.


Now when i switch with CTRL-ALT-F1-6 through my consoles they are
displaced. On CTRL-ALT-F7 where my X-Server runs the picture is fine.
When i fix it in the consoles with the "Auto-Button" the X-Server on
F7 is displaced.

Is there something wrong with the console framebuffer?

For updating to kernel 2.6.15-r1 i used my old kernel config

After i have done make menuconfig it shows me this output

.config:1317:warning: trying to assign nonexistent symbol FB_SOFT_CURSOR
.config:1426:warning: trying to assign nonexistent symbol USB_BLUETOOTH_TTY

Does the FB in FB_SOFT_CURSOR not mean FrameBuffer.

Thank you for any recommendations!

The "auto" button is for an adustment on your monitor?  If so, then
you can fix the X server displacement by creating a better modeline
with xvidtune.

It is not just the displacement, as i mentionend before the picture is
unsharp in some places too. Could this also be fixed with xvidtune.

possibly.  Did you try the shorter / taller / wider / narrower buttons?
Or the auto button? (I've never tried that one)

btw, do you have an lcd or crt?

If you have an lcd, the picture is fuzzy in places, because it's not the
right size for your lcd, and its being "stretched", which makes a few
pixels here and there in the picture get off place with the pixels of
the monitor.  (OK not a very good explanation, but this is how I
understand it :)

If you have a crt, then is it a focus issue?  Is your crt dying?  Is the
refresh rate right?

I'm kind of scraping the bottom of the barrel here.  Perhaps someone who
knows more about monitors can help...

Fuzziness is a common symptom of old monitors.   For the crappy 19"
monitor on my desk at work I have to shrink the image size to about
15" (at least 1" away from all edges) or the characters on the screen
are unreadable.

So yes, xvidtune can help if aligning or shrinking the image resolves
the problem.

Re: [gentoo-user] Display displacement

[Daniel Pielmeier]

Thank you both,

i think i understood what you mean, i will try to move and resize the
screen ouput to the right size and position with xvidtune.

Btw: i have a 19" LCD.

But i am still wondering about that i maybe have mistaken something in
my kernel-config.

I have a 19"LCD too (native resolution 1280x1024), and during boot
(no FB) and working in console (no X) sreen output is shifted to
the right side too. During boot I can see only:

" Service XY starting ...        [O "    
(" K] " is apparently missing)

I have "adjust screen" button on LCD, but it does not work.
I wanted to fix it, bud finally I gave it up. It is not a big
problem, because it is a server. But if someone know how to
fix it, I'd like to hear it too...  :-)
