I installed opensuse 11.2 on my laptop which I previously installed version 11.1 and it was working. I installed a fresh install after reboot the screen turns black and I cant do nothing, even when trying init 3 it goes to the black screen. This is a big disappointment for me. I tried the liveCD it also get into the black screen
Can you start in failsafe mode ok?
No prompt?
Just an empty black screen?
Try failsafe boot
Hi all!
I have the same problem,after install only black screen,no reaction for button pressing,only power button works-I can reboot to black screen 
Before the black screen appears, do you get the grub boot menu screen where you can select openSUSE-11.2 or 11.2 failsafe, or some other OS ?
Hi …
I Have the same problem on My Laptop ( HP tx2640er, SUSE 11.2 64bit).
Before the black screen appears,I get the grub boot menu screen where I select openSUSE-11.2 or 11.2 failsafe… I think suse can’t startX correctly…
Try the following
Pause the boot by moving the down arrow, then back up to the default boot. But now press backspace, it should delete any text where you can see: vga=0x…
Remove all text and now type just the number:
3
and hit enter
at the login type your user name and then password
now type:
su
then the root password
now type this:
sax2 -r -m 0=vesa
(N.B. the 0 is a zero not a letter)
now reboot: type: reboot
if you don’t get a gui login
login as user at cli and try this at the cli
startx
Same black screen happens to me…
If I try to boot the 64bit KDE4 LiveCD the screen will shut down just after X starts…
This did not happen with the 32bit LiveCD… So I upgraded my openSUSE 11.1 to 32bit 11.2 and it worked very well, until this morning when I got the same: the screen would shutdown.
The screen doesn’t get black !!! it shuts down, I cannot get to another terminal with CTRL+Alt+F1 etc…
I have a DELL Inspiron 1501 with Ati XPress 200M…
Even with the black screen, can you press Alt-Ctrl-F1 to bring up a text console?
Alternatively, at the grub (boot) menu, add ‘3’ to the boot option, then hit [Enter]. This should get you to a text console.
From there, log in as root, and try
sax2 -r -m 0=vesa
to create a basic xorg.conf file with the vesa graphics driver.
Type
init 5
when done. See how that goes.
WORKAROUND
I guess we all have an older ATI chip, in my case a
01:05.0 VGA compatible controller: ATI Technologies Inc RS482 [Radeon Xpress 200M]
The problem is the radeonhd driver. To workaround the problem, log in using the Failsafe option. This will give you a VESA X Server. Then use sax2 to create a xorg.conf file. In the generated xorg.conf, replace the Driver “radeon” with “ati”.

Most of the posters have said even failsafe is not working for them.
Done this…
But have only Black Screen (no console)
And computer not respond on pressing any keys(((
I had a completely dead machine. Black Screen, no apparent responses to the keyboard, no disk activity. Just completely hung up.
I managed to get into the system with the Failsafe option and a VESA X server. From there I searched for a solution and the “ati” instead of the “radeon” driver worked for me. I can now watch DVD in full screen resolution. Desktop effects however leave artifacts, so I have disabled them.
no Alt-Ctrl-F1 doesn’t work, everything is dead
I’ve done as you said, but changed
sax2 -r -m 0=ati
writing this post from openSUSE 11.2 
thanks…
Good result. It appears that as jpo234 already suggested, Xorg is trying to (incorrectly) use the radeonhd driver, instead of the ati driver.
I guess this is going to affect quite a few of us post-install, with older AMD/ATI graphics hardware.
well
doing Ctrl+C while booting and then login in as root and doing
sax2 -r -m 0=ati
managed to make it work, but I lost the auto configuration and the network management and applet is not there, manually I managed to setup my WLAN but still not applet working and mostly I think all the autoconfiguration that should run after fisrt reboot is did not work
Is there a way to run auto configuration again
Please read the openSUSE-11.2 release notes.
Simply make a backup copy of /etc/X11/xorg.conf , then delete the file /etc/X11/xorg.conf (as you have a backup) and when you reboot the auto configuration will try again. BUT you may be back to original problem.
I don’t know what happened but it identified that the installation failed and it ran the auto configuration again
but still that was unexpeced from openSUSE
thank you all
I am going to add another instance of this problem. I have an HP tx2622nr laptop which has an ATI HD3200 integrated video card. I have tried to install 11.2 from all installation medias and architectures.
Watching the machine boot up using failsafe mode the last thing seen from the screen is “Starting HAL” or something similar. The screen then flashes like it is going to bring up X and then goes black. The interesting thing is, it was working perfectly with RC2.
The xorg.conf file is actually never created. If I boot up on a live CD even under VESA it fails to boot. Anybody have any other things I can try or advice.
Yes, try this from the grub boot menu: Type ‘3’ to add to the boot options for openSUSE entry, then hit [Enter] key. This should get you to a text console. From there, log in as root, and do
sax2 -r -m 0=radeonhd (zero=)
sax2 -r -m 0=vesa (if the radeonhd option doesn’t work for you)
When finished, type
init 5
See how that goes.
Edit: In general, xorg.conf should not be necessary, but some hardware is not detected/handled properly by the Xorg sever, so running sax2 from runlevel 3 will be necessary.
