The same problem occurs on my Samsung R50 with X700 Mobility (Driver Radeon X 1950 and earlier)

Same Hardware with ML 2010.2 no problem.

CC: (none) => man-draker

No problems with my installation.

My card is an intel 82865G on-board (intel 810 and later)

If I can help with some output, call me

using ssh i've been able to attach a gdb to X11 while it was still running :

Please note that probably not all debug packages are installed but i'll try to do it, gdb does not seem to be able to do it :
warning: Unable to open "librpm-4.6.so" , missing debuginfos notifications will not be displayed

Maybe it should be rebuild against the new rpm.
Regards,

just for memory i used  service dm start && sleep 1 && gdb --pid $(pidof /etc/X11/X)  to attach to X before the crash.

Ok i managed to install more debug packages & the bt seems to be full now :

Error messages on tty:
FATAL: Module fbcon not found

Machine: Lenovo Netbook S10e
Graphics: Intel 945GME

I selected KDE for installation, in the summary I found that X was not configured. Configuration went ok but I saw that xdm was installed.

After reboot xdm comes up but it refuses to take my password. Booting into init 3 I was able to login but startx produced the error of the x server.

Please _attach_ the _FULL_ trace + GDB output.
Attach and not paste because:
1) it's then garbaged when bugzilla rewrap lines
2) it makes harder to read this bug report.

Else we miss the actuall error before the trace.

Also could you try with latest kernel as well as with kernel-linus (which is newer than main kernel)

Source RPM: x11-server-1.9.4-2.mga1.src.rpm => x11-driver-video-ati

And also attach your /var/log/gdm/:0.log, :0-greeter.log and :0-slave.log

> Please _attach_ the _FULL_ trace + GDB output.

I used John's command string (see comment #10 - resulting in a blank screen. 
I'm very busy preparing for this weekend's Linux event, so I don't have the time for any extra work and the learning I'd have to do (don't know anything about all this trace and gdb stuff), sorry.

We need the bits printed by GDB before you typed bt.
You need to attach gdb prior to X11 crashing of course.

I'm not using gdm since kdm is installed (kde4 install)  but i'll switch to gdm to provide logs as requested.

Created attachment 120 [details]
:0-log with kernel linus 2.6.38

there's no :0-greeter.log & :0-slave.log & gdm is trying to restart X on every crash with no end 
Should i attach the log with 2.6.37.4 (lasted mga kernel) since it's also failing ?

Yes you can attach it.

But beware:

Using GDB, you actually stoped the X server before it crashes.

You need to first type "cont" (you may have to do it several time
as it may be stoped by some spurious signals like SIGUSR1, SIGUSR2).

When it actually segfaults (you should see SIGSEV somewhere),
then you must type "bt full".

Not before, else it's just some random trace of where was X server
when you interupted it with GDB.

Summary: Mageia alpha2 : xorg is crashing on a fresh install on i586 arch => Mageia alpha2 : xorg is crashing on a fresh install on i586 arch with ATI card

I've some script somewhere either on mdv bugzilla or mga bugzilla in order to perform all of this (without SSH connection from another machine).

Created attachment 121 [details]
script in order to attach to X from a text terminal (vt1 to vt6)

I actually found it.
Just run "sh ./Xgdb2.sh" on a text terminal, then switch back to X11 until it segfaults.

Ok i guess i found the culprit thanks to your script :)
reading the line : 
(II) [KMS] drm report modesetting isn't supported.
i noticed that kms was not enable with my radeon driver.
So i add a /etc/modprobe.d/radeon.conf
with options radeon modeset=1
& right after X is able to start \o/
So the problem is probably to know when to enable KMS on radeon card (especially with thoses still using fglrx).
If i'm not wrong Anssi is testing that on mandriva cooker.

Regards,

OK.
Still it would be good if upstream wouldn't segfault when using UMS...

Priority: Normal => Low

Can you still attach the full trace so that we report it upstream?

Actually it's a dupe of bug #138
Could you try the patch suggested there?

This was caused by a faulty installation!
I did a fresh installation with the same installation medium (md5sum matched) and now the summary showed graphic system as "automatic" where it was "not configured" before. X is running fine, this bug does not apply here.

I think you commented on the wrong bug.
You wanted to comment the "summary" bug, didn't you?
