When trying to boot openSUSE 11.4 to 12.1 Milestone 5 live or full install images the backlight on my screen goes stops working during the boot of the graphical environment. If i enter "nomodeset" as a kernel boot parameter the boot process seems to freeze for about 5 minutes and then finally boots into the graphical environment but with a fuzzy/out of focus look. This bug has kept me from upgrading from 11.3... I am sure I'm not the only one out there. Reproducible: Always Steps to Reproduce: 1. insert 11.4 or 12.1 live or full install media 2. do not enter anything as a kernel parameter 3. watch as the backlight turns off Actual Results: with a black screen there is not much you can do. I have been able to boot using "nomodeset" kernel parameter but have not installed due to lack of fix for this issue. Expected Results: boot normally with the backlight activated hardware info: http://www.linlap.com/wiki/acer+emachines+e525 Possibly related bugs: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/772050 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/765438 https://bugzilla.kernel.org/show_bug.cgi?id=31522 http://www.linuxquestions.org/questions/slackware-14/%5Bsolved%5D-brightness... openSUSE forums post: http://forums.opensuse.org/english/get-technical-help-here/install-boot-logi...
