I wish to use the option to give more ram to the video card, I have a Intel 82810 chipset using the i810 driver and read that for open-gl rendering to work better I need to add the VideoRam option as it requires more memory than some systems alocate to it, however I do not know how to write it out or exactly what section and where in the xorg config file it should go. Any help would be appreciated as I am a bit of a noob to the whole Xorg config thing. I would like to try giving it 16mb then 24mb, 32mb etc... and see what works and what does not if any. Thanks in advance

goes into the Device section, a line something like this:
VideoRAM 32768

no quotes i think.
my xorg.conf file is located in /etc/X11
i wonder if it actually has any effect...

Thanks for the reply r00tb33r,

Does it matter where it goes before or at the end of other options ?

below is my devise section.


Section "Device"
### Available Driver options are:-
# sw_cursor is needed for some ati and radeon cards
#Option "sw_cursor"
#Option "hw_cursor"
#Option "NoAccel"
#Option "ShowCache"
#Option "ShadowFB"
#Option "UseFBDev"
#Option "Rotate"
Identifier "Card0"
# The following line is auto-generated by sidux mkxf86config
Driver "i810"
VendorName "All"
BoardName "All"
#BusID "PCI:1:0:0"
EndSection

options can go in any order inside a section as far as i know.
the above should work.
*EDIT*
thats 32mb, just an example. not sure if you need that much or if it can use that much.

Ok, Thanks! will try it out and post back results.

Well it did not work,
I tried all kinds of memory amounts. Actually the problem I was having was that if I use 16 bit color 3-D rendering was fast and smooth but I could only see the top 1/3 of screen I read that 16 bit color is all these cards can do to get 3-d rendering if I use 24 bit color you get the full screen but 3-D rendering is slow and jerky, these cards will not do 3-D in 24 bit color. On searching this issue on Google and other places I read that that allowing more video ram to graphics card has been successful in fixing the issue on some systems, unfortunately it did not on my system. I gave up, Accepting the fact that Intel has no business making graphic cards LOL!!!!!!
I ended up putting in a old Nvidia Riva TNT card it old but reliable and it has ok 3-D rendering
at least for the purpose of screen savers which I like. Thanks for the help r00tb33r

Did you check in the bios if you can pump up the allocated memory for graphics?, this is usually where it is done. If you have the option to raise it in the bios, run this command upon re-boot to see if X will raise the depth to 24 from 16:

Use defaults when answering questions.

Junior Hacker, Thanks for the reply

The bios on this HP Computer only has option to crank up the Video ram to a whopping 4mb..... Wow ! it makes my pulse rush just thinking about it. very state of the art LOL!!!!!
Like I said Intel has no business doing graphics integrate or any other form for that matter.
it would have been nice to be able to use the graphics card it came with. I put the computer together for a neighbors teenager so she has her own computer and have no worrys of spyware and viruses. Currently using Sidux Linux which is based on Debian Sid you get the latest and greatest its very nice. Since I build and give these systems away free to friends and family I prefer not to have to install extra hardware so I can save it for a system that does not come with it intragrated. Oh well such is life.

Well
It's not an issue with Intel, it's an issue with "demand". Allot of people buying their first computer know nothing about them, and don't want to spend good money in something they feel is delicate electronics that they could easily crap out because of their lack of knowledge. So computer manufacturers make a box to satisfy them as well as a knowledgeable computer user and the power user. A computer with bare minimum on-board graphics is a "value" priced computer for those too cheap to spend to much in order to get a computer. But usually there will be some expansion slots on the mobo in case you decide you want better graphics later. Because computer manufacturers want to sell a computer to everybody, they have to make these cheap boxes, and Intel will help them out because they are in the same boat, the more parts you sell, the more you make.

I do agree with you about low end computer Junior Hacker, But this box came default with a Pentium III not a celeron and memory rate of 133mhz not 100mhz that many mother boards of its time could only do. although it is a old box during the time it was produced other graphic cards were coming with 16 and 32mb it's 4mb is just sad. I don't really have any bad feeling for Intel were would computers be with out them ? but my experience is that on most computers that I have messed with that had Intel graphics video has been mediocre at best. I cant really complain, well... I guess I can and do but I shouldn't at least not to much as most of these computer that I fix up and give out are given to me for free. I do home repair for a living and am always on the look out for discarded computer sitting in a corner that nobody wants any more usualy a little conversation to the owner about it end up with them saying take it if you want it or its messed up anyway or they got a new one. Most of the time they work great but are running Windblows OS jambed up full of cookies and spyware overloaded with programs that run behind the scenes at start up to little ram and cache's filled up never been emptied. Also many times the conversation With the owner goes something like this, Have I ever defraged the hard drive what's that ? It's amazing what people give or throw away, I guess Only in America. Anyway I have come across these boxes with built in Intel graphics a couple of times and they always are the same with 3d in linux 2/3 of the screen missing showing only black it's a common thread in the help forums for i810. I don't care if it has to run in 16 bit color as the eye can't really detect to much difference anyway but I got to at least have full screen I will keep searching for a fix for the next box I get this way as I have read that some people do get it worked out.

Yup'
My old computer has the i810, 100mgz memory. But back then the average amount of memory for a computer off the shelf was 128MB, that is why they restricted the amount allocated to graphics. Yet graphics is where most of the home computer's processors resources are spent. I know what you mean about the "only in America" thing, consider it a "North" American trend, I just found a dandy a couple weeks ago at the recycle depot when I dropped one I stripped off. It has an AMD 982 or something, pretty close to 1GHz processor with Windows XP Pro, no passwords, all the data still there. The processor fan & heat sink were plugged, a little blast with the compressor and WOW!. I'm now debating on which one to give away, my old HP with an 850MGz P 111, or this one???? It's so hard to decide. This is the second computer with a plugged fan & heat sink I got from that depot that runs like a top. One thing for sure though, the next one I give away is going to either be a dual boot or strictly LInux, knowing the addiction to Windows around here, the dust will collect on the outside of the box this time, unless I do the dual boot thing. People hate having to learn how to type.

Junior Hacker,
I would keep the AMD box and give away the HP I also have a AMD 1000 mhz athalon for my main box it has a agp slot using a Nvidia gforce MX400 a lot of the older HP's I see don't have agp slots I just upgraded my processor to the Athalon in my AMD box as it had a 750mhz P7 processor in it and yes you probably guessed it the Athalon processor and Nvidia card came in a computer someone gave me that had a bad mother board so I upgraded mine. upgrading for free is the way to go. What kind of graphics did the computer you found have in it and by the way was your Intel i810 running Linux and did it do 3d in full screen for example fireworks-gl screensaver I still want to figure that one out!

I never did more than basic graphics on the HP with the i810, half the Linux distributions I tried to install on it gave me major graphics headaches, some I only got white noise, no CLI. So, if I got graphics, I stopped there and used it as is. The AMD box does have the AGP slot, but uses the on-board sis 300 graphics with 3D acceleration and 16MB memory. I have a milk box full of pci cards, and only one functional AGP graphics card in that box, ATI Technologies, Inc. 3D RAGE PRO AGP 2X (8 MB). Just haven't got to customizing it yet as I'm using it for learning forensics. But the hard decision, my old HP for some stupid reason out performs Intel P 111 1GHz processors according to the bench mark testing, and it has been a reliable work horse for working on IDE drives, it also has 6 operating systems on a larger drive than the AMD box. But life is all about sacrifices.
Apparently I got my numbers mixed up now that I look at the Everest generated report on the AMD, it has an 892GHz Duron processor. Memory read speed is 457 MB/s, the HP 850GHz P 111 memory read speed with XP Pro is 567 MB/s. But that's not an accurate comparison as the HP has a clean fresh install, and the AMD is plugged with whatever it collected over a few years. None the less, when I rebuild XP Pro on the AMD, I don't expect it to catch up to my 850 P 111, because I usually don't see a 100 MB/s jump with a fresh install, and the AMD has 512MB of memory, the P111 has 256MB, both 133Mgz.

I guess if you use the hp for testing and other stuff it's a hard call. By the way on giving out linux boxes to windows users I usually tell them I will GIVE them a good working computer that is free from getting spyware and viruses for free which usually catches there interest but I tell them that they have to make the effort in the learning curve which with KDE is not much then I show them the KDE desktop with all the goodies like superkaramba running liquid weather I show them the cool gl-screensavers which usually gets some ooo's and Ahaa's then I show them firefox browser and explain tabbed browsing plus explain openoffice and how it free and will do word format and that it can even save to pdf by default and for the younger ones a try at planet penguin racer always brings some smiles to there faces, then I remind them again that they can open there email's safely with no viruses and there computer will not get any spyware this usualy sells them over and I have had pretty good success with it with out having to dual boot with windows. I keep asking if they are still using the computers and I keep getting yeses. one thing I do is make sure that the desktop looks good with nice wallpapers, people are in to looks thats just the way it is. Usually if it looks good and can do some cool things most people like it. thats why I always like to get 3D enabled That plus you cant beat free!!!
