I use Suse9.2.

I have similar problems. I can't get the screen working on a resolution of 1400x1050. The maximum resolution I can get is 1280x1024.

Verifying the Xserver logging file has shown that the LCD flat panel display returns incorrect DDC data. Because of this the Xserver thinks 1400x1050 is not supported. Disabling DDC (in the Xserver configuration file) for the LCD display doesn't seem to work.

If I connect an external display, I can get a resolution of 1400x1050 without any problem, so the display driver seems to work.

I feel a bit sorry I can't use this notebook on Linux. I especially verified the display chipset was supported by linux (before buying the notebook).

Hi there,

i`m using Debian unstable

in my oppinion the real problem with the Intel card and the xserver is the broken vbios ... there`s just no mode for 1400x1050 so the xserver complains about it and it reduces the resolution to 1280x1024 the last suitable mode.

I`ve used the 855resolution (find it on google) tool to look into the vbios but i didn`t manage to set it right the resolution is ok but the screen gets scratched.
Similar problems appear on other Toshiba or Sony notebooks see http://linux.highsphere.net/howtos/b100b.php.

Maybe there`s a chance getting the good guys from dell to fix the problem,

so if anybody from dell reads this post please please help us ... ;)

I will continue my test with suze, and after I will follow up my using your advises.
Just one point about Dell, It's more than difficult to obtain any help from Dell, I call Dell France, and I could not get any help!!!!

Thanks, for your help. It works partially with suze 9.2, unfortunatly, I don't know why, the Xfree server does not recognize the intel video, et and he set up vesa , framebuffer driver.

I try to configuer intel driver, and he does not accept, quite strange because if I issue lspci command the intel video card look like to be well recognized.

Last point I succedded to set up only 800X600 in the vesa driver.

I will really appreciate if you could send your XFREE86 configuration file.

Thanks in advance

Does that mean that you can have a resolution of 1400x1050 with the latest Xserver?

I changed the 855resoltution tool. The bios_lock and bios_unlock function were not working.

This is how they should be:

int unlock_bios_845g_865g() {
// set permissions to read and write so I can write into shadowed VideoBIOS
outl(0x80000090, 0xcf8);
oldpam1 = inb(0xcfd);
oldpam2 = inb(0xcfe);
outl(0x80000090, 0xcf8);
outb(0x33, 0xcfd);
outb(0x33, 0xcfe);

return 1;
}

int relock_bios_845g_865g() {
// reset permissions
outl(0x80000090, 0xcf8);
outb(oldpam1, 0xcfd);
outb(oldpam2, 0xcfe);

return 1;
}

After is change the 855resolution tool worked.

you can find my xorg.conf here: http://download.el-streb.com/xorg.conf

but you have to think about the following things:

the i915 chip is only supported from the latest cvs xorg server see the changelog, my checkout date is 2005-02-28.
this is the problem why your installation is not working ... ;)

Michi

yes i know, i tried this too (exactly the same fixes) and the resolution was: 1400x1050 (if you can trust the xorg logs) so far so good .....

but the displaying is totally broken it looks like it is the wrong modeline or something simmilar.

see here: http://download.el-streb.com/d610_screen.jpg


maybe the i915 uses different values ...

and it`s working with the intel driver ?

the screen is totally filled, so the resolution is 1400x1050

Looks ugly :)

I don't know what might be wrong.
Just to verify is your screen is really in 1400x1050 you can chance the BIOS setup of your notebook and choose not to make all resolutions fit to the screen.

If your screen is not completely filled, your resolution is lower than 1400x1050.

I use the intel 915 driver downloaded from the intel WEB-site.

I put the following Options in my xorg.conf file:
(under Section "Device")
Option "IgnoreEDID"
Option "NoDDC"

I put
855resolution 34 1400 1050
in rc.local
