[Needs AGPMode quirk] [RV280 9200SE] Intrepid X crashes

Change of the package to xorg.. Feel free to change if you know better..

Same problem on a system based on an ATI Radeon 9600 (ATI Technologies Inc RV350 AP [Radeon 9600]) and on an AMD 790G chipset (Radeon x1250). The bug appears also when using the open source Radeon drivers (tested on the 9600). VGA connected Hitachi CM640ET on the first system and a CRT Philips PAL TV on the second.

This bug looks wery similar to the bugs #295994 and #289996.

For the sake of completeness I added the Xorg.0.log for the Radeon open source driver.

Please collect a full backtrace on this crash. See http://wiki.ubuntu.com/X/Backtracing for directions.

I don't know if this is a 'full backtrace' but that's what I was able to get out so far. I also included trace.

Hi Risto,

That's a very good start! The only other adjustment needed, is please install the debug package, xserver-xorg-video-ati-dbg, so we can get symbols on the calls #1-3.

ok, I did a new test today

Clean Kubuntu 8.10 install from the alternate cd.

First start: When KDM starts, I can see the cursor nice & clear but other than that I'd say there's a sync problem or something. Since I'm able to see the cursor it's something else..?

I ran updates, installed ssh and restarted.

Login & startx to see that the same problem is still there: cursor is nice and clear but the rest is a mess..

Installed xserver-xorg-core-dbg libgl1-mesa-dri-dbg xserver-xorg-video-ati-dbg (actually these were installed: libgl1-mesa-dri-dbg xserver-xorg-core-dbg xserver-xorg-video-ati-dbg xserver-xorg-video-mach64-dbg xserver-xorg-video-r128-dbg xserver-xorg-video-radeon-dbg) and added this to xorg.conf:
Section "ServerFlags"
        Option "NoTrapSignals" "true"
EndSection
and tried to backtrace but since X doesnt' crash here (see problem #1 in the first message of the bug rep)

Then I install xorg-driver-fglrx (which installed dkms fakeroot fglrx-amdcccle fglrx-kernel-source patch xorg-driver-fglrx) to try the problem #2 (actually I think I have two separate problems here - maybe this should be split in two reports, someone please tell me?)

At this point I also removed KDM..

I tried to run sudo /etc/init.d/Xorg and it started but running the open drivers, I think (same symptons).

So I run sudo dpkg-reconfigure xserver-xorg (though AFAIK it doesnt change the driver in xorg.conf) and then (for some reason) I restarted the computer (maybe it's required to install the kernel modules or something..?)

And now, finally got it crashing:

Thanks; that helps a lot. In the log and backtrace, it seems to be crashing when it's trying to open the DRM device:

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such device or address)
drmOpenDevice: open result is -1, (No such device or address)
drmOpenDevice: Open failed

The backtrace is pointing at this line (or a previous one) as where the crash is occuring:

    fd = drmOpen(RADEON_DRIVER_NAME, busId);

I think part of the problem is that installing fglrx has confused your system. You commented that with #2 you're attempting to use fglrx, but from the log and backtrace it appears to be using radeon. If you have fglrx's DRM installed, then it may be causing the conflict with starting radeon. As to why it's using radeon rather than fglrx, perhaps you've not specified fglrx as the driver in your xorg.conf. Please check this.

Let's focus this bug report on getting things working just with the open source radeon driver. Please completely purge fglrx and related packages, and reinstall the -ati driver (or do a fresh reinstall of Intrepid). Do not install fglrx. Attach the Xorg.0.log and xorg.conf from running that, as well as the output of lspci -vvnn.

Fresh Intrepid-Kubuntu-Alternate install and problem #1 appears, as expected. Three requested files attached

Will not attach xorg.conf since it's empty.

I made a quick try with Jaunty live CD, xorg.log included. I guess nothing too interesting there.
I have to give the intrepid installation hard drive for Windows :( a while so let's see when I can do some more testing, if required.

Tried this on Jaunty Alpha4 with a new monitor (DELL someting lcd) that has both VGA and DVI connectors and the same problem with both cables: the picture is fuzzy except the mouse cursor. Can I provide you with more information?

Marked as confirmed - same behaviour on several releases (Intrepid, Jaunty a4 & a5 both on DVI and VGA). Change if you don't agree.

Based on the description of the symptoms, it sort of sounds like this might be caused by an incorrect AGPMode setting, which is relevant when DRI is enabled. You should test if changing this makes the issue go away. In your /etc/X11/xorg.conf set AGPMode to various values like this:

 Section "Device"
      ...
      Option "AGPMode" "2"
 EndSection

Possible values include 1, 2, 4, 8. You can see what it's currently set to by looking in /var/log/Xorg.0.log. It's worthwhile to test all four values even once you find one that works. If this takes care of it for you, we may be able to establish a quirk to set it for your hardware combo

For more details on this, please see the "ATI AGP Mode Quirk" section at https://wiki.ubuntu.com/X/Quirks

Indeed adding
Option "AGPMode" "4"
fixes the problem!

Now I'm running Hardy w. KDE 4, I'll try Jaunty soon with this fix.

Thank you a lot Bryce!!!!!!

If there's still something I can do to get this fixed for others, let me know!

Thanks, we've enough info to put a quirk in for this now.

Great, looking forward to see this working out-of-the-box :)

Uploaded patch to Jaunty and to upstream git.

This bug was fixed in the package xserver-xorg-video-ati - 1:6.11.0-1ubuntu2
