fglrx permission troubles

[Frown]

Hello,

I have successfully installed the ATI fglrx drivers on Debian Sid, but for some reason, direct rendering only works for root:

$ fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.4.1)

$ sudo fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9550 Generic
OpenGL version string: 2.0.5814 (8.25.18)

This howto suggests to put "Mode 0666" option to the dri section, which was already there. I also tried the alternative suggestion of setting it for "video" group and adding my user there, which didn't help either.

I have no other idea and couldn't find any helpful info on that besides the howto I mentioned, so if anyone has an idea, please share.

My configuration and log files:
/etc/xorg.conf
/var/log/Xorg.0.log

[Icarus]

 Section "DRI"
    Mode 0666
 EndSection

Use that as the DRI section, no idea what that Group thing is all about
Also should have Modes in your Screen section, like so

Section "Screen"
    Identifier  "Screen0"
    Device      "Videocard0"
    Monitor     "Monitor0"
    DefaultDepth 24
    Subsection "Display"
        Depth       24
        Modes       "1400x1050" "1152x864" "1280x1024" "1024x768"
        ViewPort    0 0
    EndSubsection

As I said in the post, that was what I tried first, the group thing was just a try from the linked howto, but neither works.

Modes got detected correcly for my monitor without specifying them, so I didn't bother, but I put them there now anyway, even though it's not related to the issue I'm having.

New xorg.conf (still doesn't work)

Do you get something different with:

ldd /usr/bin/fglrxinfo

(or whatever path the fglrxinfo binary is in) versus:

sudo ldd /usr/bin/fglrxinfo

(or again, whatever path it's in)? That will print all the libraries that the fglrxinfo binary links to. If it shows different libGL paths, that may be part of the issue.

(If it shows the same thing, then you probably want to double-check that you don't have multiple fglrxinfo binaries floating around in different directories.)

[Frown]

Both give same paths and files, just the numbers in parenthesis are different (not sure what they mean, manpage doesn't seem to say):

$ ldd /usr/bin/fglrxinfo
        linux-gate.so.1 =>  (0xffffe000)
        libGL.so.1 => /usr/lib/libGL.so.1 (0xa7e73000)
        libX11.so.6 => /usr/lib/libX11.so.6 (0xa7dab000)
        libXext.so.6 => /usr/lib/libXext.so.6 (0xa7d9c000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xa7c64000)
        libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xa7c51000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xa7c4d000)
        libXau.so.6 => /usr/lib/libXau.so.6 (0xa7c4a000)
        libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xa7c45000)
        /lib/ld-linux.so.2 (0xa7f24000)
$ sudo ldd /usr/bin/fglrxinfo
        linux-gate.so.1 =>  (0xffffe000)
        libGL.so.1 => /usr/lib/libGL.so.1 (0xa7e84000)
        libX11.so.6 => /usr/lib/libX11.so.6 (0xa7dbc000)
        libXext.so.6 => /usr/lib/libXext.so.6 (0xa7dad000)
        libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xa7c75000)
        libpthread.so.0 => /lib/tls/i686/cmov/libpthread.so.0 (0xa7c62000)
        libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xa7c5e000)
        libXau.so.6 => /usr/lib/libXau.so.6 (0xa7c5b000)
        libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xa7c56000)
        /lib/ld-linux.so.2 (0xa7f35000)

I also checked for multiple fglrxinfo binaries, found three of them, all seem to be the same, and behave the same:

-rwxr-xr-x 1 root root 11064 2006-05-30 22:28 /usr/X11R6/bin/fglrxinfo
-rwxr-xr-x 1 root root 11064 2006-05-30 22:28 /usr/bin/fglrxinfo
-rwxr-xr-x 1 root root 11064 2006-05-30 22:28 /usr/bin/X11/fglrxinfo

But the problem is not just fglrxinfo, all apps that require direct rendering fail to run as normal user, but run just fine as root, for example the test program fgl_glxgears:

$ fgl_glxgears
Using GLX_SGIX_pbuffer
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  144 (GLX)
  Minor opcode of failed request:  5 (X_GLXMakeCurrent)
  Serial number of failed request:  33
  Current serial number in output stream:  33

$ sudo fgl_glxgears
Using GLX_SGIX_pbuffer
1194 frames in 5.0 seconds = 238.800 FPS
1211 frames in 5.0 seconds = 242.200 FPS

It used to work before the modular xorg 7.0 came out, since then I used the opensource ati drivers, but now I'd like 3d acceleration back so reinstalled the (newest) drivers but got into these problems...

ATI is a trip to get GLX working, I have two laptops with M9's and it's like any update will break GLX
I just got DRI working one one with a dual monitor setup, but here's my xorg.conf for the same system but with one display

i take it / files / is a bad word now??? replace the *** with / files / without the spaces...

For me, once that was working properly the dual was pretty simple.
But for you, there are more things to it then the xorg.conf, kernel option have A LOT to do with getting fglrx working properly. I use Gentoo and this page helped me almost completely. Pay close detail to the kernel config and make sure you have that set properly with the correct agp module.
