Not sure what is going on, but in the past two days, my X session has crashed. The screen goes to the black console (possibly Ctrl-Alt P7) because I see all the kernel messages, and I am unable to recover, keyboard does not respond, nothing.... I am left to do a hard reboot. When I try to check the logs, I am unable to find anything except one lone message in /var/log/daemons/errors.log that states "kdm[1712]: X server for display :0 terminated unexpectedly". It appears that no other logs have captured this message. Is there anything else I could do to get more debugging messages?

Yesterday, when it first happened, I thought it was a fluke, but it happened again today. And it also appears to have begun after the recent xml, java or cups packages update!?!? Not sure if that was a coincidence, or if there really is a problem. Cups doesn't make sense, so I doubt it's that...

Any ideas on what I could do? Anybody else having this problem?

Hard rebooting could be loosing the logs if the file was open and could not recover, on hard reset.

I suggest you enable sshd and login via another pc and do a proper reboot, rather that a reset.

Then you may catch more in the logs, or at least be able to clear any hung x session that is grabbing the screen

You're using the free radeon driver, which could be problematic by itself or due to missing firmware.
Please post the output of

Code: Select all

rpm -qa | grep firmware

and maybe consider switching to fglrx driver via drakx11.
https://wiki.mageia.org/en/Setup_the_graphical_server

Here is the output of your command:

Code: Select all

[sam@ ~]$ rpm -qa | grep firmware
kernel-firmware-20120219-1.mga2
carl9170-firmware-1.9.4-1.mga2
radeon-firmware-20120322-3.mga2.nonfree

Also wanted to add that in Mageia 1, the fglrx driver did not work well for me, so I stuck with the radeon driver. This is an older machine and I do not intense graphics or game playing on it, so the radeon driver has been fine for me.

You could try the fglrx driver again, maybe it works better now?

Apart from that, maybe you want to have a look in your ~/.xsession-errors this could have some information about the crash

I'll give the fglrx driver a try again.... what's the worst that can happen?
