Description Forgotten User --EoyBps8f 2011-11-03 09:21:47 UTC

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

I used tumbleweed with 11.4, including kernel 3.1 and there was no issue.

After dupping 11.4 to 12.1 I get a black screen while booting on my DELL notebook with intel graphics chipset. As soon as X is started the screen shows some content.

If I switch to tty1 I do not see any splash or the last boot messages but just a normal login.

Using nomodeset helps for booting but results in a low resolution for X.

Since bug 669798 states that it happens with any kernel > .37 I do not think it is the same issue.

Reproducible: Always

I have exactly the same problem with a HP Compaq 2510p (Intel GM965 graphics). Unfortunately, the installation (from DVD) is also affected and you have to use nomodeset.

*** Bug 732308 has been marked as a duplicate of this bug. ***

Comment 3 Karsten Keil 2011-12-02 16:28:41 UTC

Same here with HP Compaq 2510p.

Comment 5 Adam Spiers 2011-12-28 20:14:24 UTC

Same here on the first (and only) three machines I installed 12.1 on, all with different hardware - details are in bug 722476 comment #6.

Comment 6 Adam Spiers 2011-12-28 20:57:50 UTC

After several hours of googling I finally found a solution: boot with i915.modeset=1 rather than with nomodeset.  I also removed /etc/X11/xorg.conf*

I'm really surprised this isn't being given more attention, because it's a complete show-stopper on a wide range of hardware.  I think it should *at least* be listed on http://en.opensuse.org/openSUSE:Most_annoying_bugs_12.1

Increasing priority

Comment 8 Mark Goldstein 2012-02-03 08:04:20 UTC

I have the same issue with HP Compaq 6910P, Intel 965 Express.

Comment 9 Mark Goldstein 2012-02-03 08:32:38 UTC

In my case using i915.modeset=1 as recommended in Comment 6 does not help. I still have empty screen (backlit) and have to guess when to enter the encrypted partition password (fortunately I only encrypted one partition, so it is still possible to enter right passphrase and continue booting).

Comment 10 John Carrick Smith 2012-02-17 18:03:13 UTC

Also occurs intermittently on Dell Inspiron 6400 with Intel 945GM chipset. Happens with 3.1.9-1.4-desktop on openSuSE 12.1 and also 3.1.0 on 11.4.

Comment 13 Egbert Eich 2012-03-27 06:16:54 UTC

Please give KOTD or Tumbelweed a try.
If the problem still exist:
1. To rule out splash screen issues use splash=off as a boot option.
2. Please add drm.debug=0x4 to the boot options to get a better debugging output and attach the output of 'dmesg' right after booting.

I have installed kernel 3.3.0-4-desktop from KOTD with 12.1 and the problem appears to be solved for that.

Thanks. John

Comment 15 Egbert Eich 2012-03-27 19:19:17 UTC

Ok, since KOTD helps in this case we should be able to close this as FIXED (with KOTD) soon :)

John, thanks for testing :)

Will set this to NEEDINFO to the original reporter to see if he can resolve his isue with KOTD, too.

Comment 16 Forgotten User --EoyBps8f 2012-07-25 09:43:52 UTC

Closing?

Comment 17 Forgotten User B-7XM5iatA 2012-09-02 11:23:06 UTC

I had the same problem on my Lenovo 3000 N 100 with Intel 945 GM graphic chip.
A solution in my case was to load the kernelmodule i915 into the initial ramdisk.
 
I add the module i915 to " etc/sysconfig/kernel " section " INITRD_MODULES "
via YaST ( Editor für /etc/sysconfig ) System/Kernel/INITRD_MODULES

Comment 18 Mark Goldstein 2012-09-07 11:50:34 UTC

(In reply to comment #17)
Yep, it helped in my case too. Thanks!

Comment 19 Jeff Mahoney 2014-08-08 20:26:38 UTC

This report is against openSUSE 12.1 which is no longer under maintenance. If
you are able to reproduce it with openSUSE 13.1 or openSUSE Factory, please
re-open and reset the the "Product" field to the appropriate release.
