Hi,
Hi,

I've been banging my head against this with no luck.

I have an Asus P4p800-VM with integrated Intel 865 Graphics running testing.

My problem is that I cannot get xorg to give me 1152x864 resolution. Xorg.0.log says there is "no mode of this name". I know the hardware can do this because Windows doesn't have a problem with this.

I can get 1024x768 and 1280x1024.

After googling, I have tried:
- setting video ram to 16MB in the BIOS and in xorg.conf Device section. Xorg.0.log confirms that the driver sees 16MB. - setting the correct HorizSync and VertRefresh values in xorg.conf Monitor section. Xorg.0.log reports those values - inserting modelines in the Monitor section (the current ones are from what knoppix got from it's probe (they seemed reasonable). knoppix won't go above 1024x768). They don't seem to have any affect.

Does anybody know what "no mode of this name" means? Does it mean that i810 can't do 1152x864? Does it mean I haven't told it how to do that mode?
I think it means, that the video bios does not know that mode. Have you
checked if there is a newer bios for your mobo?

I've heard that there are resolution problems with Intel chipsets in X.
Have you tried the package 915resolution?

$ aptitude show 915resolution
Package: 915resolution

Description: resolution modify tool for Intel graphic chipset

  Wow, thanks! All that googling, and not a hint of this utility.

I've got xorg recognizing 1152x864 (no complaints in Xorg.0.log), but when I switch to that resolution, I get a blank screen. The monitor's on screen menus don't even work, so the monitor is real unhappy. Lower resolutions work fine.

xvidtune reports identical modeline parameters as I get with this monitor on another Debian system running XFree86 (I'm switching with a KVM), so I'm at a loss as to how to attack this. Any ideas?

I'm sooo close.

Did you try the usual "switch to the console and then back to X" trick?
I.e. Ctrl-Atl-F1 Alt-F7.
Yup. I used the switch back and forth thing to run xvidtune from the console so I could check what xvidtune thought was happening with the non-functional resolutions. It really looks like all the X stuff is working the way it's supposed to (computing it's own ModeLines etc), but my monitor is not happy with i810.

What's more, now it's starting making a high pitched noise when I use 1152x864 with my XFree86 system (though not with Windows which is using a lower refresh rate). I may have damaged it.


Also, try without the Modelines in your xorg.conf, if you haven't
already. Just put the HorizSync and VertRefresh in your Monitor section
and the desired Modes in your Screen section.

I had tried it without the ModeLines, and got the same result. xvidtune confirms that xorg is computing the same ModeLine parameters as my XFree86 based system does.

I'm going to try some Modelines with lower refresh rates, to see if I can get some sort of image and get rid of the whistle.

Longer term, I think I'll probably buy cheap ATI or NVIDIA card. The Intel onboard video is not worse the hassle.

Thanks for the tips.
