help with OpenGL

Hi,
I have a problem which I assume has to do with a badly configured GL rendering or something. If I run glxgears, I get c. 450 FPS, and the error message: 

libGL error: open DRM failed (Operation not permitted)
libGL error: reverting to (slow) indirect rendering

I guess something is wrong, but I don't know what. I know the machine (a compaq nx5000 laptop) is capable of a quicker rendering, because when I ran Mepis, it worked fine.
So, I need some advice on what to do, and how to do it.
1. How do I find out which drivers I need, if that's the problem?
2. Which settings do I need to do, and where? xorg.conf?
3. Anything else...?

Re: help with OpenGL

first of all we need this:
- graphic-oriented infos of your xorg.conf
- kernel-modul
- output from: glxinfo | grep render
- added yourself to the video-group?

thx

sorry for my bad english smile

Re: help with OpenGL

450 FPS? That's really weird, you should get 90-120 or thereabouts with software rendering.

What's the video hardware? Try 'hwd -s'...

No, Sempron 2200.

Argh! Forgot that HWD doesn't recognize the new version of X... Blegh.

Try 'lshwd'. With the new version of xorg, it won't give you the right module, but it should tell you what your hardware is.

Re: help with OpenGL

- graphic-oriented infos of your xorg.conf - see below

- kernel-modul - kernel 2.6.14_ARCH
Modul? I know this is overkill, but I have pasted the entire output from lsmod below.

- output from: glxinfo | grep render 

glxinfo |grep render                              Sun 01 Jan 02:05:10

libGL error: reverting to (slow) indirect rendering
direct rendering: No
OpenGL renderer string: Mesa GLX Indirect

- added yourself to the video-group?
yes - now, but no effect

Re: help with OpenGL

Hmm... I'm pretty sure you're not supposed to have both the i810 and i915 modules loaded.

(BTW, you should probably enable AUTODETECT and specify your filesystem modules in mkinitrd.conf and make a new initrd.)

Edit: Aha... The Wiki's got it.

Anyway, try just loading the i810 module. If that doesn't work, try using only i915... But remember that *both* modules are to be used with Xorg's i810 driver.

Re: help with OpenGL

Thanks - that worked. I don't quite understand why, though - I changed the xorg.conf according to the info in the wiki link. Here's the old (commented out) and the new settings:  

#Section "Device"
#    Identifier  "Card0"
#    Driver      "i810"
#    VendorName  "All"
#    BoardName   "All"
#EndSection

Section "Device"
   Identifier  "device0"
   VendorName  "Intel Corp."
   BoardName  "Unknown Board"
   Driver      "i810"
   BusID "PCI:0:2:0" #may vary?
EndSection

So the changes are: the identifier (which I then changed accordingly in the Section "Screen"), the Vendor and BoardName, and the extra line BusID. Is that what did it?

Re: help with OpenGL

Hm. OK. May I ask one more question, cause this is beginning to look like another one of those: "Arch is great, but sometimes - just sometimes - I'd consider accepting a few seconds extra boot time for the comfort of a "find-all-for-ya" distro like Mepis or knoppix" cases for me.
So, is this something chipset specific, is it something that another xorg-conf-generator than hwd would have found for me, is it something every linux user but me naturally knows (I doubt it, because I haven't seen it mentioned anywhere), and (yes, I know I asked for ONE more, but hey, it's new year...!) what is this BusID anyway? 
(I should also say that despite my occasional feeling of "I want this to JUST WORK", "I wanna go back to Mepis", this forum is and has been a great help, both through direct answers to my questions, and for the previous answers, which have helped me on numerous occasions)

Re: help with OpenGL

The busid tells Xorg where your videocard can be found.

I think this is chipset related, but you could always try one of those find-all distros and copy the relevant part from their xorg.conf to yours.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

Expanding on Lone_Wolf's comment, here's a chunk from the xorg.conf commentary. Comments are worth reading eyolf, as they will answer many of your questions - I'm not trying to sound sarcastic when I say that. This particular chunk below is in the VGA section of xorg.conf:

# The BusID line is used to specify which of possibly multiple devices
# this section is intended for.  When this line isn't present, a device
# section can only match up with the primary video device.  For PCI
# devices a line like the following could be used.  This line should not
# normally be included unless there is more than one video device
# installed.

Re: help with OpenGL

Point taken,  and I do read all those comments, the man files, the wikis and whatnot, and I have found those an invaluable resource in the Arch installation. In this particular case, there are no such comments in my xorg.conf file, however. This is probably due to the fact that I initially used the recommended hwd -x routine to generate the file, and replaced the original. If that is the problem, there should probably be a line in the wiki to  recommend keeping the default xorg.conf for future reference, because (etc.)

I suspected this might be the case; that's understandable then.
