Hi,
I have been having loads of trouble getting the 3D accelleartion to work on my new laptop. For a long time I could not get the i810 driver to load for the i915GM card, but I was told to switch to xorg 6.9. I did this, and the i810 driver now loads in X. I have compiled the agpgart, and chipset stuff for my card in the kernel as modules, and load them. The modules I have loaded are: intel_agp, i915, drm, and agpgart. What happens now though is X will start with the i810 driver (or maybe it falls back to vesa, I'm not sure, I was running vesa before this and it works, but no 3D accell), but I have no 3D accelleration still. My output from glxinfo is:

--- CUT ---

So I went and looked in Xorg.0.log and the relevant info is:

--- CUT ---

(EE) Failed to load module "glx" (module does not exist, 0)
(WW) The directory "/opt/kde3/share/fonts" does not exist.
(WW) Warning, couldn't open module glx

--- CUT ---

So it looks like I lost the glx module somehow. Where did it go, and how do I get it back? The bad checksum thing is probably because I am using 915resolution in order to get the right resolution on my monitor, as if I dont use it, it is stuck in 1024x768 or something. I try to load glx and dri in my xorg.conf, and have switched it around so it will not load dri, but that does not seem to help. Also, I do not think it is listed there, but if I just started "X" from a console and then killed it, it was saying it couldn't find /dev/agpgart, that it did not exist, but I checked, and it does exist. This computer has been the biggest pain to get things working right on, I swear.

I got glx working, aparantly the file was in the wrong place, so I moved it to where it was looking for the extentions, and it finds out. However now DRI doesn't work. When running glxinfo I get:

When I look in Xorg.0.log I see:

--- CUT ---

(EE) I810(0): [dri] DRIScreenInit failed. Disabling DRI.

--- CUT ---

Anybody know what thats about? Does it have to do with the way the 915GM is suppost to be able to do multiple screens, and how two of them are detected in lspci? It also says that stuff about how the other one is not listed in xorg.conf. I don't care right now weather the other works, I just want the main one to work right, but it would be good if it had something to do with that and I could kill two birds with one stone.

I FINALLY got glx and dri working right! The frame rates arn't what I hoped for though. It says direct rendering is enabled and working properly, but it just seems a bit slower then it should be. I only get about 800fps on glxgears. Shouldn't it be a bit faster?

Can you tell me how you got the DRI working?? Thanks.

This stumped me for a while, and I'm still not sure why exactly it didn't work. I had read in all the guides that you should compile agpgart support and DRM support as modules, so I went back and compiled them as modules before I started messing with stuff. When I finally got to the part where DRI was not starting, I did some poking around, and in dmesg (I think) it would say something about how it could not use the agpgart module. I messed with that for a few hours and couldn't figure out why, because it seemed to be working fine for everything else. I finally went back and recompiled my kernel with agpgart and DRM support IN the kernel (not as modules, but actually compiled in there) deviating from all the guides I have saw, rebooted, loaded X, and DRI worked. Don't ask me why. My only guess is there is some kind of bug in the module part of either the agpgart or DRM portions of the kernel that made it not work as a module when using it with my card, or a buggy compile, something like that, or a bug in the way my system was loading the modules (which doesn't make much sence, because I have other things compiled as modules, and they work fine), but it worked.

So try recompiling the kernel and making sure agpgart and DRM are compiled IN the kernel, not as modules. If you do that, make sure to tell it not to autoload the agpgart and drm modules on startup, because they shouldn't need to be there anymore anyway.

Hope this helps,
Marshall

Thanks, Oxagast. I'll try to recompile my kernel and I'll let you know what happens. Thanks again.

Good News!!! Good News!!! I did not have to recompile my Mepis Kernel.... I so not looking forward to that. I'm not the programing type... I did however modify my xorg.conf to reflect the 1400x1050 option and made that my "max" resolution and I restarted X and it worked. I even rebooted to make sure it would hold and YES!!!! it did!!!! I appreciate all those who contributed to this thread becuase you guys and girls have helped me tremendously. Thanks Oxagast et al....

Thats good. I wonder why having it run at a different resolution would affect weather DRI worked or not. Do you happen to know?
