Yeah thanks, I made the post on campus and couldn't remember exactly what it was. Glad to see it worked and you were able to figure out what I was saying! :lol:

You can avoid having to do the nasty inject of XFree86 by using:
Code:

emerge --nodeps nvidia-glx


One caveat - I'm not too sure how this will affect emerge -u world or emerge -U world of your system, but on mine it seems OK.

@LeTene

That's another way of doing it for specific ebuilds, but(on my system at least), emerge -U world would still want to emerge xfree, by injecting it it no longer wants to do this, and I can emerge away no problems.

Is it still the case that XFree needs to be injected to stop it from being installed ?

I thought with the latest package of Xorg, that XFree was blocked (the B that shows up), so that it won't install while Xorg is installed ?

I have xorg and gnome 2.6 installed on my PC. When I do a emerge -p kde, it doesn't list trying to install XFree ?

oook I'm confused. What's the big bru-ha about xorg vs xfree? Is xorg supposed to be an order of magnitude better or some such? My system must be rock stable as I use it for work 99% of my day. The only thing I took a chance on was the 2.6.5 kernel which is working perfectly for me, presently using devfs, but in the next incarnation of this machine I intend to kill that and use udev. Will xorg be any better for me? I need extremely fast vid response, and sadly at the moment I still have some dropped frames in movies, and rendering is a bit slow which I attribute to the processors.

My machine is:

dual p3-933 procs on a tyan tiger 230T motherboard (Apollo Pro133T chipset), using a geforce4 Ti 4200 128mb and nvidia 4496 kernel and matching glx in twinview mode.

any ideas here?

It's a licensing issue. Search the damn forum, that's why there's that search box smack on every page.

No better and no worse than XFree86 4.3.99-someversion since it's a very recent fork of the XFree86 codebase - a fork of the last version under the old license.

Then you've just answered your own dilemma - if it must be stable, leave it alone. Duh.

All of the following takes place on a fresh installation (I was checking out kde before I emerged the nvidia packages and thats how I noticed the change)...

After emerging nvidia-kernel and nvidia-glx (had to inject xfree), I modified my /etc/X11/xorg.conf by uncommenting glx and changing nv to nvidia in the driver section for my gfx card. When I restarted X and logged back into kde I found that all my fonts were now big and ugly (I will post a screenshot if nessecary).

I had not changed one thing apart from what was mentioned above. It may be worth noting that the first time I tried restarting X it failed to start but everything was ok after a reboot.

If you would like me to post my entire xorg.conf or just certain sections then please say so.

It may be something else, but I had that same problem with xfree when I first installed it. Turned out my monitor was lying to the card (the interpretation of this was different with the latest xfree compared to the older version). This statement in the XF86Config device section for the vid card cured it, but it may or may not be so with your problem (could be different default fonts?) with xorg. It can't hurt to try it though.

Well I cannot thank you enough, this fixed the problem!! Do you have a link that explains why this solution works, can you explain it yourself or will a simple forum search suffice?
What does the NoDDC option do?

i found the info either on the nvidia site, or in the docs from a downloaded copy directly from nvidia one time.. it encompasses 2 other older options which i dont remember, but basically what it says to the nvidia kernel is "my monitor lies about itself. do not believe it. accept only what i tell you via my xf86config file and ignore the monitor's insane ravings"

that's basically it. one of my monitors swears it can only do 1024x768 but the monitor specs and my own experiments show it to handle 1600x1200 with ease. i dont know why, but it appears that the font changes from the default when the monitor is believed.

i am sure a proper technical explanation can be found on the nvidia site. i forgot most of that since this happened a while ago. i have been using that option for more than a year.

Thanks for that, the Nvidia readme confirms you have a good memory :lol:

Just in case anyone else is interested here are the relavent sections from the Nvidia drivers readme...

Quote:

Option "NoDDC" "boolean"
Synonym for "IgnoreEDID"


Quote:

HOW MODES ARE VALIDATED

During the PreInit phase of the X server, the NVIDIA X driver validates
all requested modes by doing the following:

o Take the intersection of the HorizSync and VertRefresh ranges given
by the user in the XF86Config with the ranges reported by the monitor
in the EDID (Extended Display Identification Data); this behavior
can be disabled by using the "IgnoreEDID" option in which case the
X driver will blindly accept the HorizSync and VertRefresh ranges
given by the user.

When that happened to me, I had to manually build/install the modules for my kernel using the instructions in the nvidia-glx README...

I have the same problem as described in this thread:
https://forums.gentoo.org/viewtopic.php?t=142490

Basically, my nvidia drivers get loaded correctly at boot (as shown via lsmod); however, when X.org tries to start, it complains it cannot load the nvidia drivers.

I am working with a CLEAN gentoo install using kernel 2.6.5 (gentoo-dev-sources). Anyone else having this problem?


EXACTLY the same problem. ACCEPT_KEYWORDS="~amd64" or "amd64" nvidia-glx/kernel drivers, 2.6.5-r1 gentoo-dev-sources

Dmesg shows no errors on the load of the nvidia module (taints kernel, of course... but no errors)... tried every nvagp option in xorg.conf...

A solution would be appreciated :)

What this sounds like to me is you need to is try the following:

Make sure your nvidia driver is set to load in /etc/modules.autoload.d/kernel-2.6

If they are, proceed to next step

As per my original post, when you originally setup gentoo, there was a part where you had to look for all modules (one of them's the nvidia driver). Once you find that it is there, try deleting this file.

try then re-emerging the nvidia-drivers, then reboot.......cross your fingers too, that might help :wink:

Still didn't work for me :cry:

Negeus' solution is worth a try, but it will have to wait until the AM. Caffiene has run out and I'm done.

Funny thing was I HAD glx working perfectly under xfree until someone suggested I try reemerging xfree with a couple of different use flags. That's when I got into trouble. I removed the new use flags and tried again to remerge xfree. Now glx was "broken".

I'll bet that sometime between my last update of xfree and when I tried to reemerge xfree I must have changed or added or deleted a use flag(s) that it all needs to work. And now the problem has carried over when I installed xorg.

Nutterpc, care to share your use flags used to emerge xorg?

Well, what are the USE flags you emerged X.Org with? cat /var/db/pkg/x11-base/xorg-x11-6.7.0/USE

Now I too have switched to X.org with no hassle at all!

All I did was:
Code:
emerge -C xfree
ACCEPT_KEYWORDS="~x86" emerge xorg
ACCEPT_KEYWORDS="~x86" emerge nvidia-kernel nvidia-glx corefonts

And basically I was set! I just backed up my old XF86Config-4 before and copied + edited it for fonts. Rocks like ninja! :)

(You've just gotta LOVE the faster startup time!!!) :wink:

I'm working on a fresh install, and decided to go with xorg right from go.

It just finished compiling, and etc-update has informed me that I have 257 files that need updating.

257 files!

Keep in mind, this is a fresh install. The only things I've done past the end of the install guide is install the bootsplash/framebuffer.

Is this many files to update normal? I was just curious. I almost fell off my chair.
