Hi,
First of all, thanks to everybody for trying to make things work.
Now, to the problem. I have this brazilian notebook, Novadata N8800,
actually a Compal CY27 (?), or similar. Using lspci, I get for the
graphics card:
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)
Right now, under Linux, X (Free86 or Org) only works in 800x600 or
640x480. It can not make 1024x768.
I tried both versions of the 855resolution utility on my notebook. None
worked. Previously, I have tried XFree4.4, and XFree 4.3.X with and
without the 855patch from Christian Zietz. None worked either.
WinXP runs under 1024x768, and the X server from XiG also runs under
1024x768. WinXP tells that the VBIOS version is "2880".
When I do "855resolution -l" with version 0.1, I get:
Chipset: 855GM

Mode 5c : 3856x2320, 32 bits/pixel
And, when I use version 0.2, the output is:

Before patching the VBIOS with 855resolution, Xorg.0.log tells me that
the X.org server found only two "Built-in modes", 800x600 and 640x480,
and that it is not going to use "1024x768 mode":
(II) I810(0): Monitor0: Using hsync range of
31.50-48.50 kHz
(II) I810(0): Monitor0: Using vrefresh range of 40.00-70.00 Hz
(II) I810(0): Not using mode "1024x768" (no mode of this name)
(II) I810(0): Increasing the scanline pitch to allow tiling mode (800
-> 1024).(--) I810(0): Virtual size is 800x600 (pitch 1024)
(**) I810(0): *Built-in mode "800x600" <<<<<=============
(**) I810(0): *Built-in mode "640x480" <<<<<=============
(==) I810(0): DPI set to (75, 75)
(II) Loading sub module "fb"
after using "855resolution 43 1024 768" (version 0.2), to replace the
mode 800x600 by 1024x768, the respective output of X.org is:
(II) I810(0): Monitor0: Using hsync range of
31.50-48.50 kHz
(II) I810(0): Monitor0: Using vrefresh range of 40.00-70.00 Hz
(II) I810(0): Not using mode "1024x768" (no mode of this name)
(II) I810(0): Not using mode "800x600" (no mode of this name)
(II) I810(0): Increasing the scanline pitch to allow tiling mode (640
-> 1024).(--) I810(0): Virtual size is 640x480 (pitch 1024)
(**) I810(0): *Built-in mode "640x480" <<<<<=============
(==) I810(0): DPI set to (75, 75)
(II) Loading sub module "fb"
So, I loose the 800x600 mode, and 1024x768 still does not work.
I read a lot on the net about this chipset and its memory allocation
problems on some versions of the VBIOS. Regarding this, without using
855resolution, X.org tells me:

Note that it complains about a "Bad V_BIOS checksum" after running
855resolution.
My (wrong?) guess is that there is a "table" somewhere in my VBIOS,
telling which modes are available (the "Built in" modes), so, replacing
the timings only does not work. Does anybody else has these "Built-in
mode" messages on the X log?
Any ideas? It´s really annoying to work under 800x600 :'( .
Thanks a lot.

Sergio

Hi,
So, there are at least 2 kinds of different VBIOS structures :
the more common "type 1" structure was described by Andrew Tipton,
(http://www.leog.net/fujp_forum/topic.asp?TOPIC_ID=5371)
and the "type 2" is what the 0.1 version of 855resolution knows
how to patch (VBIOS structure of, at least, the Dell 510m).
The 0.2 version of 855resolution is now available. I modularized
it around plugins to be able to patch differents VBIOS.
I don't know how to compute the several resolution values of
the "type 1". If you know how, please, look into the file
plugins/plugin1.c to put the formulas. So, for the moment, this
0.2 version is only a test. But perhaps it could work because the
LCD screens don't use the different frequence values.
Can you test it (http://perso.wanadoo.fr/apoirier/) ?
Regards
