Description f1r31c3r 2010-06-03 15:26:13 UTC 
I can see how this bug developed, drivers 10.4 did not compile against the new kernel 2.6.34 so a 10.5 was released which compiled against the latest kernel.

I am having severe problems with the EDID information from my second monitor this occured on all previous drivers to date but on this version it segfaults on the second monitor turning it off. I have tried multiple ways to manually modeline my second monitor to no avail. 
This is why i dropped back to a previous kernel version currently 2.6.33-gentoo-r2. Compiling the 10.5 Ebuid against this kernel version when my kernel symlinks point to 2.6.34 kernel version compiles.

Yup the Ebuild compiles disregard of my symlinks which predictably has an effect when i startx. The driver X.org log shows version mismatch to the running kernel and shuts off DRI.

Ebuild is broken there.

The same problem weather DRI fails or not occurs with segmentation faults from the driver on the second monitor

Xorg.log
(II) fglrx(0): Connected Display0: DFP on internal TMDS [tmds1]
(II) fglrx(0):  Display0: Failed to get EDID information. 
(II) fglrx(0): Connected Display1: DFP on secondary TMDS [tmds2i]
(II) fglrx(0): Display1 EDID data ---------------------------

Its not the monitor or the cable Both have been tested Maybe the Card or driver but 10.4 against 2.6.33-rc builds worked both heads fine even with the EDID error.

The predicted result from the Ebuild compiling against the incorrect Kernel Symlink:

(WW) fglrx(0): Kernel Module version does *not* match driver.
(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work
(II) fglrx(0): [uki] removed 1 reserved context for kernel

(WW) fglrx(0): * no 3D acceleration available                *
(WW) fglrx(0): ********************************************* *

10.4/10.5 is rather broken against kernel 2.6.34 yet 10.4 works well with the previous 2.6.33-rc versions.

I am going to try and change my symlinks back to point to 2.6.33-rc kernel and recompile. Try see if the multi monitor segfault still exists.

Reproducible: Always

Steps to Reproduce:
1.Install ATI-drivers-10.5 for Multi DVI displays second display renders disabled no matter what.
2.Reboot with Kernel linux-2.6.33-gentoo-r2 and compile ATI-drivers-10.5 against this version while /usr/src/linux symlinks point to kernel-2.6.34
3.Load X and observe errors Note same monitor behaviour disabling of the second monitor with segfaults when trying to change or enable the monitor. Even tried pointing the xorg.conf to use the second display and segfault output to console.

Note my current emerge --info shows me running on the prior kernel version where DRI fails. This is so i can show you the errors and that it builds against this kernel version with the wrong Symlinks.

Actual Results:  
Multi Monitor fails Second monitor becomes disabled and segmentation faults occur on every occurrence trying to enable. I feel it maybe related to the bellow error in the xorg log. Both monitors are identical models

(II) fglrx(0): Connected Display0: DFP on internal TMDS [tmds1]
(II) fglrx(0):  Display0: Failed to get EDID information. 
(II) fglrx(0): Connected Display1: DFP on secondary TMDS [tmds2i]
(II) fglrx(0): Display1 EDID data ---------------------------

Driver result when compiled against the incorrect kernel

(EE) fglrx(0): incompatible kernel module detected - HW accelerated OpenGL will not work
(II) fglrx(0): [uki] removed 1 reserved context for kernel

(WW) fglrx(0): * no 3D acceleration available                *
(WW) fglrx(0): ********************************************* *

Expected Results:  
Loaded multi display properly without segmentation fault errors or EDID errors and errored to me when i tried to compile it against incorrect symlink on kernel version. The Drivers have always checked the symlink against the running kernel in previous versions due to the above outcome. If the software has changed so it relies only on headers and not kernel versions how come it mismatches and fails to work.

My symlink:

linux -> /usr/src/linux-2.6.34-gentoo
Comment 1 f1r31c3r 2010-06-03 15:55:27 UTC 
Confirmed the DRI failure behaviour by changing the Symlinks linux -> /usr/src/linux-2.6.33-gentoo-r2 the correct running kernel for test and reloading the DRI returns with full 3D rendering.

But the EDID failure on the second monitor remains, causing the second monitor to become disabled due to no capabilities information missing which in turn segmentation faults when configuration is attempted.

I listed bug as an Ebuild bug due to the Ebuild compiling against the wrong symlinks or ignoring them causing the DRI failure which i can now confirm due to version mismatch.

I am lost as to how i am to fix this error with multi display urm.

Please advise if i need to split the bug into two faults. 
Thanks
Comment 2 f1r31c3r 2010-06-03 17:10:50 UTC 
Here is my EDID DDC output from the roll-back ati-drivers-10.4 against kernel 2.6.33-gentoo-rc2.

As you can see it pulls in a small amount from display0 something that fails completely on 10.5 driver. On roll-back the configuration state was left in a mess I had to use amdcccle control applet to set the configuration, reboot several times before the gnome display properties could see the second monitor and allow it to be multi desktop configured. 

There is something changed more than was listed in the change-log from 10.4 to 10.5.

If i switch the display connectors over as mentioned above the screens move over but the effect in the log bellow is identical. something is not working correctly.

The unmodified xorg.conf after rolling back, i have deleted nothing modified nothing this is untouched after the amdccle config utility blatted it to get my monitors running.

No this is not an ebuild bug, the ebuild compiles the module for the kernel pointed by /usr/src/linux so if it is .34 it will install the .34 module under /lib/modules/2.6.34-gentoo so the .33 kernel is still using the old module that's why you get the missmatch.

About your second monitor problem i *think* it is an upstream bug, at least sound like to be. Anyway the .34 kernel is not supported at all by catalyst 10.5 but the ebuild use an unofficial patch to make it work with .34
Comment 4 Enrico Tagliavini 2010-10-03 12:09:35 UTC 
Some news. I just bought a second full hd monitor. Multi display works as expected
I removed my old xorg.conf then generated a new one with aticonfig --initial=dual-head then i used amdcccle to configure the display settings (it needed some step here to be honest before getting the 1920x1080 res). this with ati-drivers-10.9-r1

The EDID error is not related to the driver i think, but i might be wrong.

Does it still fails for you?

I close this bug, no activity for a long time
