I've been using openSuse 10.3 for about 6 months now. I wanted to install Compiz Fusion for window effects, but found out that I needed to update my video card drivers.

In the instructions, it said to press Ctrl-Alt-Backspace to restart X without rebooting. However, it took me out to a command line, asking me to login, etc. At first, I didn't realize what happened, so I shut down. When I booted up again, it booted to the command line and didn't load X.

Then I tried to start X manually. xinit gave the following error:
(EE) No devices detected.

Fatal server error:
no screens found

startx throws the same error.

How should I go about starting X now?

The laptop has an ATI Mobility Radeon chipset. The following line is in /var/log/Xorg.0.log:
(--) PCI:*(1:5:0) ATI Technologies Inc RS300M AGP [Radeon Mobility 9100IGP] rev 0, Mem @ 0xf0000000/27, 0xe8100000/16, I/O @ 0x9000/8

After installing the new drivers, I executed "aticonfig --initial" (without quotes, this was in the instructions) to configure X to use the new drivers.

After it kept booting to the command line, I re-ran that command with the following output:
Found fglrx primary device section
Nothing to do, terminating

Then, I also tried running "X -configure", but it threw the following error:
Number of created screens does not match the number of detected devices.
Configuration failed.

I hope this helps.

Sounds like the fglrx driver didn't load properly.

Here's what the device section of /etc/X11/xorg.conf looks like on my machine:

If you are still having problems, try and install the fglrx driver by executing the .run file (rather than installing from rpm (or deb)).
