That exact issue happened to me in 12.0 and it ended up simply being a video configuration problem. Run xorgsetup (as root) from console, or even better run xorgconfig if you know the specifics of your monitor, etc. That will generate a proper video configuration for you. This worked for me.

That appears to be your problem. Looks to me like it's not finding the real-time clock it is looking for.

Are you using the huge kernel or the generic kernel?

If you are using ATI, get the proprietary drivers and install them as that is what i discovered to be my error.

i am using the full kernel,at the start i selected the hugesmp type which was the default.well i dont understand the non detection of clock part because if i dont use the xserver for too long it works fine.only after long hours do i see such problems.

Can u please tell me where would the ATI be used??i did not facwe ny such problems in slackware 10.2 with the 2.4 kernel.

Well you should use a proprietary ATI driver if your graphics card is ATI. If that is the case, I suggest using the fglrx slackBuilds. Similarly, if you are using an Nvidia card there are nvidia slackBuilds for that as well. If you need and install any of these you will have to modify your xorg.conf. If you aren't using a special graphics card like these then you probably don't have to worry about this.

I'm thinking your problem is something to do with your system's power management (ACPI), and perhaps a module is being loaded that shouldn't be. It is generally suggested that you use the generic kernels with an initrd instead of the huge kernel. /boot/README.initrd tells you how to make your initrd. You could also try turning ACPI off (at boot or by unloading it after boot) and see if that has any useful effect.

I had a similar problem when logging out of KDE or switching user occasionally the screen would go black i.e. X would crash. This would happen maybe 1 time in 10. What fixed it for me was to remove the ATI drivers.
