Black sceen after Grub: VNC, SSH and RRM work fine

today I have updated OpenSuse 11.2 to 11.3.
When the system boots I can see BIOS output and selftest.
After GRUB is passed the screen goes black, but boot process is continued to “init 3”. SSH and all daemons work fine.
I get a screen on the remote inside board, but no output on the attached LCD (Graphic: ATI ES1000 on board). I seams that output is redirected to “Remote Inside Board” only.

Any idea, how to switch output back to screen?

Thank you.

Try failsafe

Also try , in accordance with the openSUSE-11.3 release notes, the boot parameter “nomodeset”.

Thank you all for your quick replies.

  • Failsafe did not work. When testing “radeon_cp” the screen blanks.
  • “nomodeset” worked. I got a 640x400 console in runlevel 3.
  • gnome is starting in 1280x1024, but false colors (screen is all greenish)

Now my questions:
-Is it now possible to increase resolution while booting again?

  • I can not start sax2

Sorry for my stupid questions, but I am only using Linux and not so familiar with trouble shooting.

More information is needed.

When you boot to a workable resolution (either 640x480 (ugly) or 1024x768 green (also ugly)) check to see what graphic driver is in use? KDE has a “my computer” icon one can check. Maybe Gnome has too ?

You could also, for each of those two approaches, copy the content of /var/log/Xorg.0.log to - #1 paste tool since 2002! and press submit on that site, and then post here the URL/website/address that it gives. Do NOT post those files directly here.

The /var/log/Xorg.0.log sometimes has useful information to explain what is happening. Also sometimes the file /home/username/.xsession-errors has useful information. Again, do NOT post that file here, but rather indirectly point to a copy of it on

sax2 has been dropped from openSUSE. Novell announced they could not maintain it any more and asked for volunteers from the openSUSE community to take over the maintenance. No one volunteered. Hence it was dropped. If you search the build service, you will find it is available for 11.3, packaged by a couple of different users (last time I looked), but not it has not been maintained so it may not work.

Graphics have changed signficantly between openSUSE-11.1 and 11.3, with 11.2 being an intermediary step.

My apologies for the silly question, but did you read the openSUSE-11.3 release notes wrt graphics and nomodeset?

I have uploaded both logs:

  1. 455.137] X.Org X Server - Ruediger_Xorg.0.log - FF4wML55 -](
  2. /etc/X11/xim: Checking whether - Ruediger_.xsexxion-errors - MwrhBPTa -

Thank you for the information about sax2
To your question: I know RTFM :wink: but yes - I have read the release notes -but to be honest-, it is not clear to me which efects it has on my system. My knowledge is not deep enough to considder the information properly. I hoped when updateing the system, that my configuration is kept or adopted.

Please, when you obtained the Xorg.0.log file, was that with the 640x480 resolution with nomodeset ? or with the green coloured 1024x768 resolution with nomodeset?

How many monitors do you have connected? Exactly what is your monitor ? (manuf/model). It appears to be trying to setup a number of different monitors? I’m wondering if that might be the problem ?

Reference the 11.3 release note comments being difficult to interpret applicability - that was my experience also - definitely not written for the neophyte like myself.

Started with “nomodeset” in 640x480. logged in and started “gdm”. Gnome started 1280x1024 - but tainted green.

I suppose OS becomes confused due to the RMM-Board inside. Since it is obviously appearing as a second screen/display. The monitor is attached via KVM, since the server is deployed in the data center. Monitor is a NEC MuliSync LCD 1990 SXi.

Update: I will make an installation from the scratch in order to find out the reason. Got an image as fallback.

Update2: Clean install is working fine with “nomodeset” and KDE. Without “nomodeset” same problems.

Since the effort to reinstall the complete system is by far too much, I will do a fall back via image to OpenSuse 11.2. Thank you for your support!


By fine I assume you mean with proper resolution.

Indeed with the availability of liveCDs, I always check first with a liveCD before I waste time on a full install. Of our 6 PCs at home, I still have 1 on openSUSE-11.2 and 1 on openSUSE-11.1 (with remainder on 11.3).

Good luck !
