RH9 uses XFree86 version 4.3.0... According to the /usr/X11R6/lib/X11/doc/Status intel 845G is supported. The driver to try would be i810 ... look at http://www.xfree86.org/4.3.0/i810.4.html for details about settings.

If it doesn't want to play, you should be able to make some headway with either the vesa driver or the fbdev driver (the latter assumes that the kernel is doing vesa graphics... rather limited, since you will be "locked" to the mode chosen for the kernel (probably by a vga=... kernel command line), but perhaps a bit more stable when switching between console<->X than vesa... At least in my experience).

I've made this work with all three methods on a Compaq SFF EVO D510S with i845G "Intel Extreme graphics"... The two vesa-alternatives with XFree86 versions prior to 4.3.0 (where there are no alternatives), and the i810 alternative with 4.3.0.

RH8 uses version 4.2.0, so that might be why you see problems... I wouldn't hazard to guess as to what Solaris 8 use:-).
If you manually replace 4.2.0 for RH8 with 4.3.0, I'd expect you'll need change /etc/X11/XF86Config manually.

What is the nature of your problems? Did you try with generic vesa support?

yes, i m aware xfree86 4.3.0 supports 845G...but mine is 845GL. I tried using xfree86 4.3.0 for my solaris 8. It works but i stil need to boot it from CD and reconfigure X windows every time cos it doesnt boot up and it keeps saying the configuration is incorrect. I tried the VESA support and even the generic VGA with all the possible combinations but to no avail:<

There is no difference from the driver perspective;).
Look at intels http://downloadfinder.intel.com/scripts-df-external/filter_results.aspx?strTypes=all&ProductID=865&OSFullName=Linux*&strOSs=39&submit=Go%21 page... You end up on that regardless if you go from the 845G or 845GL HW page. All the different 845G chipsets share the same driver.

Now RH8 should work after a fashion with vesa... Not great, but... well, as I said, it's a bit more stable with kernel framebuffer vesa.
Solaris 8 isn't my strong point, but I'd imagine that the trouble you see isn't directly connected with the driver (rather with replacing the default X install witrh 4.3.0 ... can be a bit tricky on some OSes).
RH9 will just work.

Using the default solaris x drivers is worse...i could at least see some light with xfree86 4.3. Ironically i have installed solaris 8 in my laptop with trident cyberbladei1 successfully bcos it is supported by xfree86 a few versions ago.

Anyway thks, anybody else has any experience on this issue?

Do you dualboot solaris and RH8? Why not chance the upgradeto RH9 then?-) If it doesn't want to play in RH8, the situation is bound to be better... or at least no worse with RH9;-).

Yes... you do talk about both though, so it's an easy "misstake":).

You built 4.3.0 from source?

nope i didnt built 4.3.0 from source....i am wondering if there is a problem with my board as when i tried to put in a ATI 3D rage pro II on my PCI there seems to be some conflict...the card, supposingly working, cannot co exist with my on board Intel Extreme Graphics(845GL)..i.e  845GL doesnt even work when the ATI rage is in it and the latter couldnt work properly either....so annoying... maybe i shall give up on solaris n go into RH9...

Sounds like a plan:-).

In ancient history, there've been some few "onboardgraphics chips" that needed a strap to disable them (if you wanted to avoid this type of resource conflict). More modern ones "autodisable", so there shouldn't be a need to do it manually.... In fact, there usually isn't any way to do it manually... Perhaps it'll only do so for an AGP card? Oh well.

Sorry I can't give you more help with the Solaris config bit (I only have some old SPARC-based ones)... You've posed a question about that in the Solaris TA?

"i stil need to boot it from CD and reconfigure X windows every time"

you have more than one XFree86 config file.
examine XF logs, configurators use /etc/X11/XF86Config, Xserver uses sometimes different

       XFree86  uses  a  configuration file called XF86Config for
       its initial setup.  This configuration  file  is  searched
       for  in the following places when the server is started as
       a normal user:

           /etc/X11/<cmdline>
           /usr/X11R6/etc/X11/<cmdline>
           /etc/X11/$XF86CONFIG
           /usr/X11R6/etc/X11/$XF86CONFIG
           /etc/X11/XF86Config-4
           /etc/X11/XF86Config
           /etc/XF86Config
           /usr/X11R6/etc/X11/XF86Config.<hostname>
           /usr/X11R6/etc/X11/XF86Config-4
           /usr/X11R6/etc/X11/XF86Config
           /usr/X11R6/lib/X11/XF86Config.<hostname>
           /usr/X11R6/lib/X11/XF86Config-4
           /usr/X11R6/lib/X11/XF86Config

       where <cmdline> is a relative path (with  no  ".."  compo­
       nents) specified with the -xf86config command line option,
       $XF86CONFIG is the relative path (with no ".." components)
       specified  by that environment variable, and <hostname> is
       the machines hostname as reported by gethostname(3).

       When the X server is started by the "root" user, the  con­
       fig file search locations are as follows:

           <cmdline>
           /etc/X11/<cmdline>
           /usr/X11R6/etc/X11/<cmdline>
           $XF86CONFIG
           /etc/X11/$XF86CONFIG
           /usr/X11R6/etc/X11/$XF86CONFIG
           $HOME/XF86Config
           /etc/X11/XF86Config-4
           /etc/X11/XF86Config
           /etc/XF86Config
           /usr/X11R6/etc/X11/XF86Config.<hostname>
           /usr/X11R6/etc/X11/XF86Config-4
           /usr/X11R6/etc/X11/XF86Config
           /usr/X11R6/lib/X11/XF86Config.<hostname>
           /usr/X11R6/lib/X11/XF86Config-4
           /usr/X11R6/lib/X11/XF86Config

       where <cmdline> is the path specified with the -xf86config
       command line option (which may be absolute  or  relative),
       $XF86CONFIG  is  the  path  specified  by that environment
       variable (absolute or relative), $HOME is the path  speci­

Um sure... I thought it might be something more like <the configurator works on file A>, <the boot scripts copy file B onto file A>.... but I don't have solaris for intel... and my sparcs don't run X (pure server use), so I cannot check if/what/where... variations on a theme:-).

Redhat-9.0 fully supports i845 series graphics cards...even DRI is wroking fine on my computer...I had to do no tweaks with the settings for that..just install Redhat-9.0 and everything will be configured...

845GL is quite recent( called Extreme Graphics 2), with many new 3D features, no VESA support sometimes, NOT explicitly supported by i810 driver of version 4.3.0.

This one is good:

Not there either
http://www.xfree86.org/current/i810.4.html

so Intel drivers are the only ones working still

it looks like an XFree driver to me, not an intel driver -- or did I miss something?

Think the point gheist is making is that G but not GL is mentioned.

I simply have i845GL on workstation maiboard, it does not work with i845G support from 4.3.0, display problem was solved with Radeon 8xyz

so I suggested http://support.intel.com/support/graphics/linux/graphics.htm link as very promising, which I cannot check, because I do not run Linux ....
