https://bugzilla.novell.com/show_bug.cgi?id=767391 https://bugzilla.novell.com/show_bug.cgi?id=767391#c0 Summary: Black Screen during boot with KSM and without nomodeset Classification: openSUSE Product: openSUSE 12.2 Version: Beta 1 Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: matis_l@tlen.pl QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2 Hello, When I try to run OpenSUSE 12.2 beta1 from LiveCD KDE on x86-64 architecture i see only black screen. I mean the system is booting up and I can see later a KDE splashscreen but with outside strong light - the image is very blurred and build-in backlight of a monitor/screen does not work. When I run LiveCD with nomodeset parameter everything is OK but the only resolution which I can choose is 1024x768 on a widescreen. My hardware is E-Machines notebook E525.

Then the backlight is working, but the screen-resolution is fixed on 1024x768 (instead of the native resolution of the Widescreen-Laptop) The other way that should work is according to some forum entries i studied to write the following line in the "/etc/init.d/boot.local": "setpci -s 00:02.0 F4.B=0" This will fix the backlight to maximum. In any case I think this is a problem of the Kernel itself (KMS). I'd also tried Ubuntu Live CD in a new version with the same result. The problem with that graphic controller alredy started with OpenSuse 11.4 which switched to KMS. Hope that there will be a solution very soon. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
