intel845 video problem & RedHat 8
 

Help!!!

A lot of people seem to have problem with the intel motherboard and the intel845GL video chipset. It seems that red hat 8 doesnot support it correctly. The problem is that the only resolution one can run is 640x480 at 16bit color depth, if one wants to increase resolution he must also decrease color depth down to 256colors, which is unacceptable. That definetely says that the drivers are not working correctly.

Could you please somebody provide a solution to this problem. I have read a lot of threads on this problem but nobody seems to reply a solution. Are there any new drivers for this video chipset? Can we write our own drivers if yes how?

If anybody has any ideas they are welcome.

At one point about a week ago I asked Jeremy (who runs this site) to put the sentence:

The Intel 845GL chipset is a....

and something I don't want to type after the 'a', as a banner accross the front of the site.

The problem isn't with RedHat, its with the kernel and the XFree86 project. There's a lot of work that's gotta go into this and Intel hasn't been all that helpful. If you poke around Intel's website, you can get minimal usage out of the board by enabling VESA, but really you're better off using a PCI video card for the time being. Yes, its a mess.

I foun a solution that it worked with my system.

On the BIOS of your PC change the graphics buffer from 1MB to 8MB. This will allow resolution of 1024x768 and 16bit color depth.

RedHat is running on my PC, great.

I am also facing the same ptroblem...
after setting my graphics buffer from 1MB to 8MB...do i have to change the /etc/x11/xf86config file device driver "vesa" ?
i am having video ram while installing redhat 8.0 i should give 64mb right ?
what abt the system speed ?does it alter ?
in mandrake 9.0 also can it be solved changing the graphics buffer ?

Actually, as of XFree86 4.2.99-4, there is support for this chipset without having to use any lame framebuffering. It'll take a binary install of XFree, RPMs aren't going to happen for a loooooooong time, and technically you're running beta, but you get the real graphics card, none of this vesa stuff.

This actually works ! I'm running the standard RedHat 8.0 distro kernel 2.4.18-14 and x 4.2.0

I have a Intel Desktop Board D845GLAD with the on board video and audio using the 845GL chipset and onboard
PRO/100 lan (thats the onlything thats worked right)
I got this board thinking i got a good deal on a good product. was i wrong.


this is what i did as taken from intels website
http://support.intel.com/support/gra...x/graphics.htm

i downloaded the i830-20030120-i386-linux.tar from intel's website under support

installed the kernel source from the redhat cd2

rpm -iv kernel-source-2.4.18-14.i386.rpm

RedHat 8.0 cd2 /RedHat/RPMS/kernel-source-2.4.18.14.i386.rpm
(this maybe different depending on your distro, do an ls -l -d kernel* in your RPMS dir)

then i ran "make dep" in the kernel source directory standard rh 8 is in the /usr/src/

again ls -l -d kernel*


then i extracted the tar file:
tar -zxvf i830-20030120-i386-linux.tar

which extract the files to a directory called dripkg

i ran ./install.sh in that directory

followed the prompts, preatty straitforward

run the XFree86 -configure

and you should be home free

this actually fixed the problem now it works 100% correctly

in my case X had already probed the right video card, the driver just didn't work right

now i have to figure out why the audio doesn't work

Audio subsystem for 82801DB AC '97 processing using the SigmaTel STAC9750/66 codec

Intel 845 - resolution limitation - possible solution
 

Hi,

I have a D845GVAD2 motherboard from Intel. XWindows was not coming up after a fresh installation of RedHat 8.0. I had standard RedHat 8.0 distro kernel 2.4.18-14 and X 4.2.0.


1024x768 or 600x800 resolutions are supported after I did BOTH these steps:
1. Increase Graphics mem to 8MB in BIOS
2. Follow steps mentioned by nz1845 (thank you, nz1845)

I extracted the .tar file in a temp directory (/root/X86). I hope things would still work fine if I delete this X86 directory.

Installation of latest XFree86 from xfree86.org did not help - system hung when the last step 'XFree86 -configure' was to be executed.

Sound still does not work. Hope someone can offer a solution to this.

Cheers,
Siva

Greaaaaaaat....
 

Hey guys,
I had a problem with my X in Redhat 8. because of my intel 845GL. I was only able to run in 16bit and 600X800. or in 256 colors and the next higher resolution.. 1024x...

I installed the package ie the tar file given in the intel website and now i can get very good resolution. Anybody who had the same problem as mentioned above must go to the intel support website as mentioned above.

But still my sound card is not working... it has the same intel 845GL as its audio chip i suppose.

try this site and it might give a just of XWindows on RH

hi everyone,
we have RH8 on dell Optiplex GX260

i've already did video buffer=8MB,
that enabled us get through RH anyways :)
GNOME works without any problem, but KDE has problems although it accepts 1024*768...
the panel seems like very small, and both panel+desktop seems like not very smooth...
terminal is something like doesn't work properly, not showing anything properly but confused...

if i did't have the prob with video card, i would suspect the RH and configurations, but i worked on other systems without any prob with default conf.s ...

any experiance?
thanx in advance

You're effectively using a 64 Mb video card as an 8Mb video card with no acceleration at all, its just going to look bad.

XFree86 4.3.0 took care of vesa issue and there is now a native driver for the i845 series video chipsets. Unfortunately RH 8.0 shipped with XFree86 4.2.1, so you can either do a binary install of 4.3.0, or really... upgrade to RH 9.0 and just start with the better X-server.

Cheers,

thanx lots for the quick reply...
i'll do that ASAP, was on my mind anyways...

i'll share the result here, so others can get some ???s cleared experimentally :) ...

tara!

Hi everybody,
I had a problem with XFree86 on intel 845 (which comes with HP Pavilion 503n) only low resolutions were available. I have installed binaries for xfree86 version 4.3 and 1024x768 become
available. But for some reason there are some kind of electric waves on the monitor (looks like it is all the time refreshing) when I run RH8 in this resolution. When I switch back to lower resolution using crtl+alt+"-" these waves dissapear. Please, advise how it can be fixed!
P.S. For some reason windows XP is running fine on the same hardware in the same resolution mode. :scratch: :scratch: :scratch:

Hi. I've read how hard you tried to run i845. I did the same about month ago
I've also succeeded to run DRI for this card.
I use Slackware, 2.4.20 kernel and 4.3.0 XFree
I tried not to compile any beta code, but I cannot trust I havent
So everything works fine with ONE PROBLEM:

when I switch to console, from time to time my X crashes, freezing whole
system for about 15 seconds and producing this message to console:
====================================

Anyone have seen something similar before ?
