Description Bart Otten 2011-10-06 11:40:32 UTC

User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

I have an iMac 27" with the resolution of 2560x1600. The installation of Beta1 does not show up. The screen flickers for half a second and then remains black. The system seems to be unresponsive.

If I select 1600x1200 in the installation bootmenu, it does work but it's very very small.

Reproducible: Always

Steps to Reproduce:
1. Get yourself an iMac with the resolution of 2560x1600
2. Boot and start openSUSE 12.1 installation without selecting a resolution
3.
Actual Results:  
When images are loaded a blank screen is presented. The system seems to be unresponsive.

Expected Results:  
GUI of openSUSE Installation

I have the same issue with my 2005 Dell Diemension B110 with an Intel 865G graphics card. This issue is also in RC 1 as well as the Beta.

with vey very small you mean 1600x1200 or smaller?

that the default modus does not work for installation is bad, but wouldn't be critical

Should I file a separate bug for my hardware? My machine will freeze if I set it to a lower resolution.

Sorry for the double-comment. The power went out the very moment I hit Commit so I didn't know if I got the commit in or not.

I have just burned a DVD of 12.1 and tried it in three different machines: a Dell Latitude D630, an old Dell Inspiron 6400, and an unbranded whitebox desktop machine.  EVERY single one of these exhibited the blank screen problem - am I unbelievably unlucky, or is this an unresolved critical bug affecting many machines?

In every case, adding 'nomodeset' to the kernel boot parameters worked around it, although I am wondering if there is a more optimal workaround which selects a decent video mode.  I tried the VESA option but that didn't help.

Happy to provide extra debug if someone can indicate what info is needed.

Comment 7 Adam Spiers 2011-12-28 20:11:50 UTC

Removing NEEDINFO since the original reporter seems to have stopped responding.  If you still require debug info, please set NEEDINFO to me and I will provide.

However, isn't this a duplicate of bug 727978 or even bug 669798? (both of which are still in the NEW state despite being marked as Critical and having duplicates of their own ...)

Comment 8 Adam Spiers 2011-12-28 20:59:19 UTC

I finally found a better solution than 'nomodeset' - see bug 727978 comment #6.

Comment 9 Stefan Dirsch 2015-01-07 14:37:23 UTC

Product is no longer supported. In case the issue is still reproducable on a maintainerd product (at that momement: openSUSE 13.1 or later), feel free to reopen.
