Does this problem keep your computer running at 640 x 480 resolution? I
installed FC3T1 on a Dell computer with an 828656 Graphics Controller. I
could run system-config-display as root, setup the resolution, but
display is still in 640 x 480 mode.
GUI ---> System Settings > Display

With the gnome-display-settings program.
GUI --> Preferences > Screen Resolution, it would not allow any choices.

I believe there was mention by someone awhile ago about this problem,
I'm not sure they got an answer back or found a solution. Since it is
still in test1, I assume the problem is still there.

Is this card supposed to be recognized as an 845?

No, it shows up as;
00:01.0 VGA compatible controller: Intel Corp. 82810E DC-133 CGC [Chipset
Graphics Controller] (rev 03)

I think your talking about an X problem right? I'm just trying to do a
console framebuffer with the i810fb driver.

Yep! This is with X. I saw the 810 and didn't think about what the fb meant for framebuffering.



But as for why you would maybe having problems with X on a Dell with that chipset.... Check into your logs and see if it is having a problem allocating video memory. Dell has this habit of breaking intel firmware by changing the I/O address for shadow memory allocation after they recieve working boards from their manufacturers. So what could be happening to you is when X tries to allocate the shared memory, it hits intels normal I/O address, finds nothing there and gives up with about 1 meg of memory to use which pretty much gives you 640x480 at 24bpp. You can try setting it to 16pbb and 800x600, or 8bpp at 1024x768 and see if it give you the resolution your after. (and that will tell you if you have a dell hacked/broken intel firmware)

The 1 meg memory suggestion was given on another list also. I'll look into this tommorrow to see if the BIOS is setup to 1 meg and increase it for a fix attempt. The computer hasrev A03 BIOS so I'll probably have to try some settings in xorg.conf that were suggested.



If that is the case (like you have something like a Inspiron 1100, 5100, m500. you didn't specify or I could better help you) A workaround for X has been committed to both branches (xorg and xfree86) about a year ago. So FC2T1 might already include it... But it is specific to the Dell model.


This machine has a P4 processor w/ multithreading. I never paid attention to the exact model. (committed to memory) I'll check the model of the machine out when I get to work.

Thanks for the info regarding the I/O addressing and other ideas.
