Hi,

I have a Compal CY27 laptop. The graphics chipset is (as reported by
lspci):
:00:02.0 VGA compatible controller: Intel Corp. 82852/855GM
Integrated Graphics Device (rev 02)
:00:02.1 Display controller: Intel Corp. 82852/855GM Integrated
Graphics Device (rev 02)

The 82852GM supports two independent display. You
have one at 00:02:.0 and the other at 00:02.1. You are configured to use
BusID "PCI:0:2:0". I am not sure which video port 0:2:0 drivers.
One thing you can try is change BusID to "PCI:0:2:1".

I read all material on the net about the memory/vbios problems with
this
chipset. I do not think I have this problem because I can change the
memory allocated to the graphics card in the BIOS setup program, and
the
XFree output reflects these changes.
I have tried all kinds of patchs, all the latest XFree versions
available (including 4.4.0), several distros (FC1, FC2, Mandrake 10
and
now, Debian unstable), the IBM driver, asked the dealer and manufacturer
for a BIOS update, but my LCD never reaches 1024x768 (only 800x600
and
640x480). Actually, a few months ago, I gave out trying to make the
LCD
work under 1024x768, after all this dozens of failed trials.
I am getting back to this because I just find out that, if I connect
a
external CRT monitor (actually a Samsung SyncMaster 700p) to the CRT
out
of my laptop, 1024x768 works on it! I am completely puzzled.
I suspect the reason it works is that your system
have two graphics controller. And one of it is the 350Mhz 24-bit RAMDAC
that support a regular scan analog monitor.
If XFree
can make the external monitor works on 1024x768, why it can not do
the
same with the LCD?
LCD and CRT don't use same code.

I was told that my graphics chipset has a vbios problem that prevents
Xfree from recognizing its ability to work under 1024x768, but, if
this
is true, why that external CRT works under 1024x768?
I must note that under WinXP the LCD works on 1024x768 and that the
XiG
X server can also do the same.
Now that it is clear that Xfree can produce 1024x768 with my chipset
and
my LCD supports 1024x768, how can I force Xfree to try 1024x768 on
the LCD?
My XF86Config-4 can be found here:
http://paginas.terra.com.br/educacao/nqnsome/xf86config.txt
The XFree output can be found here:
http://paginas.terra.com.br/educacao/nqnsome/xfree_output.txt
I am really sorry for my bad English.
Thanks a lot for your assistance.

Hi,
Thanks a lot for replying, really!
The 82852GM supports two independent display. You have one at 00:02:.0 
and the other at 00:02.1. You are configured to use BusID  
PCI:0:2:0. I am not sure which video port 0:2:0 drivers. One thing

works is that your system have two graphics controller. And one of it 
is the 350Mhz 24-bit RAMDAC that support a regular scan analog monitor.
Are these BusIDs related to the display pipes reported in the Xfree log:
...
(II) I810(0): Display Info: CRT: attached: TRUE, present: TRUE, size: (800,600)
(II) I810(0): Display Info: TV: attached: FALSE, present: TRUE, size: (800,600)
(II) I810(0): Display Info: DFP (digital flat panel): attached: FALSE, present: 
FALSE, size: (0,0)
(II) I810(0): Display Info: LFP (local flat panel): attached: TRUE, present: 
TRUE, size: (1024,768)
(II) I810(0): Display Info: TV2 (second TV): attached: FALSE, present: FALSE, 
size: (0,0)
(II) I810(0): Display Info: DFP2 (second digital flat panel): attached: FALSE, 
present: FALSE, size: (0,0)
(II) I810(0): Currently active displays on Pipe A:
(II) I810(0):   CRT
(II) I810(0): No active displays on Pipe B.
...
I mean:
Display Pipe A = BusID PCI:0:2:0
Display Pipe B = BusID PCI:0:2:1
or vice-versa?
LCD and CRT don't use same code.
I am sorry, I do not understand this. Why the codes are differente?
In the Xfree log I see:
...
I810(0): VESA VBE DDC supported
(II) I810(0): VESA VBE DDC Level 2
(II) I810(0): VESA VBE DDC transfer in appr. 1 sec.
(II) I810(0): VESA VBE DDC read successfully
(II) I810(0): Manufacturer: SAM  Model: 1d13  Serial#: 0
(II) I810(0): Year: 1997  Week: 46
(II) I810(0): EDID Version: 1.1
...
I am far from beingg an expert on this, so forgive me if this a stupid 
question, but what is VESA VBE DCC Level 2? It seems to be some kind o 
protocol that allows the X11 driver to communicate with the CRT and get 
information about it (Manufacturer, Model, etc.). If that is true, where 
is all this information stored? In some chip at the CRT?

When X11 tryes to read this same information from the LCD (the LFP found 
by X11, reported to support 1024x768...), it returns a error saying that 
it could not read the info. Could this be problem, I mean, the LFP is 
not able to send to the X11 driver this information? Can´t I 
configure/enter this information by hand?

Thanks a lot again.

Sergio

We didn't lose the game; we just ran out of time. If you ever reach total enlightenment while drinking beer, I bet it makes beer shoot out your nose. Make everything as simple as possible, but not simpler. The power of accurate observation is frequently called cynicism by those who don't have it. Egotist: a person more interested in himself than in me. You can widen your life by yourself, but to deepen it you need a friend. A clever man commits no minor blunders. A kiss is a lovely trick designed by nature to stop speech when words become superfluous. Always remember that I have taken more out of alcohol than alcohol has taken out of me. Drinking provides a beautiful excuse to pursue the one activity that truly gives me pleasure -- hooking up with fat, hairy girls. While we are postponing, life speeds by. Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. Black holes are where God divided by zero. The Eskimo has fifty-two names for snow because it is important to them; there ought to be as many for love. A book may lie dormant for fifty years or for two thousand years in a forgotten corner of a library, only to reveal, upon being opened, the marvels or the abysses that it contains, or the line that seems to have been written for me alone. In this respect the writer is not different from any other human being: whatever we say or do can have far-reaching consequences. Yesterday is a dream, tomorrow but a vision. But today well lived makes every yesterday a dream of happiness, and every tomorrow a vision of hope. Look well, therefore to this day. Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin. Sometimes when reading Goethe I have the paralyzing suspicion that he is trying to be funny. How wrong it is for a woman to expect the man to build the world she wants, rather than to create it herself. Why is it drug addicts and computer afficionados are both called users? Any man who is under 30, and is not a liberal, has not heart; and any man who is over 30, and is not a conservative, has no brains. I would like to believe when I die that I have given myself away like a tree that sows seed every spring and never counts the loss, because it is not loss, it is adding to future life. It is the tree's way of being. Strongly rooted perhaps, but spilling out its treasure on the wind. Whether you think that you can, or that you can't, you are usually right. Obstacles are those frightful things you see when you take your eyes off your goal. When you have to kill a man, it costs nothing to be polite. Love takes up where knowledge leaves off. Love is composed of a single soul inhabiting two bodies. Grove giveth and Gates taketh away. I'll moider da bum. If a man does his best, what else is there? Very little is needed to make a happy life. It is all within yourself, in your way of thinking. Everything in excess! To enjoy the flavor of life, take big bites. Moderation is for monks. I feel sorry for people who don't drink. When they wake up in the morning, that's as good as they're going to feel all day. Dancing is silent poetry. Solitude, if rightly used, becomes not only a privilege but a necessity. Only a superficial soul fears to fraternize with itself. The artist is nothing without the gift, but the gift is nothing without work. If you are going through hell, keep going. What the world really needs is more love and less paper work. When love is not madness, it is not love. Talent does what it can; genius does what it must. A friendship founded on business is better than a business founded on friendship. When ideas fail, words come in very handy. There are people in the world so hungry, that God cannot appear to them except in the form of bread. There are two ways of constructing a software design; one way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. The only difference between me and a madman is that I'm not mad. In the End, we will remember not the words of our enemies, but the silence of our friends. When ideas fail, words come in very handy. What do you take me for, an idiot? Blessed is the man who, having nothing to say, abstains from giving us wordy evidence of the fact. When solving problems, dig at the roots instead of just hacking at the leaves. A witty saying proves nothing. When you're in love you never really know whether your elation comes from the qualities of the one you love, or if it attributes them to her; whether the light which surrounds her like a halo comes from you, from her, or from the meeting of your sparks. First they ignore you, then they laugh at you, then they fight you, then you win. Anyone who considers arithmetical methods of producing random digits is, of course, in a state of sin. The opposite of a correct statement is a false statement.

your chip has two display controllers and two outputs, a DAC for

handled by one chip.

Alex is correct. Let focus on the primary display controller on  PCI:0:2:0 with 
Display Pipe A and Display Pipe B.
In your case you can only have PipeA=CRT and PipeB=LCD (LFP).

That is why you have the following information
(II) I810(0): Display Info: CRT: attached: TRUE, present: TRUE, size: (800,600)
 (II) I810(0): Display Info: LFP (local flat panel): attached: TRUE, present:

The problem is why XFree is saying there is no active display on Pipe B
 (II) I810(0): No active displays on Pipe B

There is a technical meaning for 02.1 It is on PCI Bus 0, Device Id 2 function

Now I understand the Pipes, but is still a mistery for me why lspci 
sees the 0:2:1, if it is a Windows placeholder (propably because I do 
not understand what a placeholder is...).

Regarding the No active displays on Pipe B, this probably happens 
because, before starting X, I disable the LCD with the keyboard sequence 
FN+F5. If I do not do this, the screen becomes unreadble (I guess 
because the CRT works in 1024x768 and the LCD do not).

Thanks a lot for the explanations, but I would like to return to the 
question why the CRT works under 1024x768 and the LCD not. Can this be 
related to the VESA VBE DCC that does not work on the LCD?

when the windows driver claims the pci resources, it gives them each a
name and they show up in the windows device manager.  the second
subfunction is just there so they can have two video devices show up
in the device manager.

 Regarding the No active displays on Pipe B, this probably happens
 because, before starting X, I disable the LCD with the keyboard sequence
 FN+F5. If I do not do this, the screen becomes unreadble (I guess
 because the CRT works in 1024x768 and the LCD do not).

that's the problem.  the i810 driver relies on the bios to deal with
outputs and modes.  if tyou use the bios to disable an ouput, the
driver probably has problems detecting an attached device.

 
 Thanks a lot for the explanations, but I would like to return to the
 question why the CRT works under 1024x768 and the LCD not. Can this be

If you boot up on the LCD and have the 1024x768 mode as your only
listed mode, also check that VertRefresh is set to 60.

Does that work ? If not, post the log file.

 Hi,

 Thanks again.

 Alex is correct. Let focus on the primary display controller on  PCI:0:2:0

 In your case you can only have PipeA=CRT and PipeB=LCD (LFP).
 
 That is why you have the following information
 (II) I810(0): Display Info: CRT: attached: TRUE, present: TRUE, size: 
 (800,600)
  (II) I810(0): Display Info: LFP (local flat panel): attached: TRUE, 
  present: TRUE, size: (1024,768)
 
 The problem is why XFree is saying there is no active display on Pipe B
  (II) I810(0): No active displays on Pipe B
 
 
 
 you can use the monitorlayout option to force on the pipes.  see the
 i810 man page.

 Now I understand the Pipes, but is still a mistery for me why lspci
 sees the 0:2:1, if it is a Windows placeholder (propably because I do
 not understand what a placeholder is...).

 Regarding the No active displays on Pipe B, this probably happens
 because, before starting X, I disable the LCD with the keyboard sequence
 FN+F5. If I do not do this, the screen becomes unreadble

I became aware of  this problem few years back (since 2003). The first time I 
experienced it  was with a DELL laptop, and I didn't have free time then to 
debug it when I actually  had the laptop. I going to see if I can figure the 
problem out (why the LCD is not working) just by reading the code.


 (I guess
 because the CRT works in 1024x768 and the LCD do not).

Not exactly. Both the crt and lcd support 1024x768



 Thanks a lot for the explanations, but I would like to return to the
 question why the CRT works under 1024x768 and the LCD not. Can this be
 related to the VESA VBE DCC that does not work on the LCD?

no



 Thanks again.

I've already done work in this area.

And I've got a driver up at

if anyone wants to test it.

Re: External CRT works on 1024x768 but LCD not. Please Help!!!

Hi,
Thanks for answering.
1)Booting only on the LCD does not work. The XFree output is here:
http://paginas.terra.com.br/educacao/nqnsome/xfree_output_lcd_only.txt
Note that X11 does not find anymore the Built-in mode 1024x768, that
it finds when the CRT is attached and I turn off the LCD before starting
X11. Why turning the LCD on prevents X11 from finding the Built-in
mode 1024x768? Isn´t the mode Built-in?
2)If I boot with both devices attached to the notebook and turned on,
1024x768 does not work in any of them. The output is here:
http://paginas.terra.com.br/educacao/nqnsome/xfree_output_both.txt
3)If I boot with both devices attached to notebook, but with the LCD
off, X11 finds the Built-in mode 1024x768 and the CRT starts in
1024x768. If I try to turn the LCD on, the screen gets messed up, and I
have to restart X in order to see something. When I restart, both the
CRT and LCD turn to 800x600.
I was told months ago that the Built-in modes are read from the VBIOS,
but this does not seem to be the whole true, since the attached display
device interferes in the detection.
BTW, the LCD works in 1024x768 in WinXP.
Thanks a lot for your attention,
Regards,
Sergio
