Hi all, new to linux.
This is my fourth day with it. I'm using Gentoo kernel version 2.6.17. I've had all kinds of problems of course, but I've been able to fix them all except this one.
I did an emerge ati-drivers to try to get some 3d acceleration and I can't get the opengl to work.
I did a glxinfo | grep direct in a terminal window to see if direct rendering was working and it spit this out at me: ERROR: version mismatch - 2D module [8.27.10] incompatible with OGL client module [8.28.8]
I've been reading all kinds of guides and can't figure this out.

Relevant hardware info:
asus a8n deluxe
radeon x1800
athlon x2 4800+ (I'm using the x86 64 version of gentoo btw)
1 gig of ram

I'm sure I left loads of info out, but I'm an utter n00b at linux.
Just ask if you need any.
Any help would be appreciated.

Have you already emerged X? Did you include ATI in your make.conf?

There's probably a whole list of things i havent done. As I said, I'm new to linux.
I just looked this up and saw I'm supposed to add VIDEO_CARDS to my make.conf file. What specifically am I supposed to add afterwards? And I see im supposed to add agpgart support into my kernel but I don't see my motherboard listed
in the kernel config. It's an nforce 4 motherboard so it should nvidia should be there, correct?

-P.S.
I hate feeling like an idiot

someone herehttp://www.linux.org.ru/view-message.jsp?msgid=1547225
seems to have fixed it somehow. Unfortunately, I don't speak russian

lol I don't either so I guess we'll have to figure out for ourselves. Did you know that we have a Gentoo ATI setup guide?? This looks like it would help you a lot.

The point of putting the video in your make.conf file is so when you emerge x it will emerge the neccesary video drivers to go with it.

Also, I seem to remember that you need to enable fglrx in xorg.conf. Not sure how good my memory is on that one.

http://gentoo-wiki.com/HOWTO_ATI_Drivers

That's the gentoo-wiki.org how-to for the ATI drivers. I love gentoo-wiki.org... don't know what I'd do without it.

Hope you can fix your problem.


http://www.gentoo.org/doc/en/ati-faq.xml <=== sometimes I find those to be a bit out of date in comparison to gentoo-wiki.org. Other times I find gentoo-wiki a bit out of date compared to gentoo.org.

I don't know if I ever really find the official docs out of date or not, but I have submitted bugs in the past to get them changed due to Gentoo itself changing. I, personally, have always felt like the docs kept it simple and safe (good for newbies) and the wiki was more of a hacker approach to it (good for the "been there done that" crowd). A lot of times both get you where you want to be, but I tend to trust the docs more as not everything in the wiki is guaranteed. Don't get me wrong, I love the wiki myself and I try to contribute on a regular basis. So in the end checking both should tell you everything you need to know. Thanks for the additional material!

A friend of mine from IRC helped me fix it. The problem was I installed the version directly from ati's website instead of using emerge. I guess gentoo or whatever it was doesn't like that version. I had to uninstall those and run emerge ati-drivers. I am currently having a problem that may be related to this but it belongs in another forum. Look for new post in software forum. Thanks all

Glad you got it fixed. Gentoo dosen't hate ATIs drivers, its just that they've programmed everything to work together better if you use the ones from emerge.
