The same happens when applying "telinit 5". Login via network is possible. Environment opensuse 13.1, with various updates Dell XPS 15, with nvidia and 3200/1800 display Detailed description opensuse 13.1 was successfully installed without any trouble on the machine and worked for a while, with few minor quirkses (like touch-capability available only after suspend-to-ram once, a known issue). All of a sudden (well, after closing the lid, like many times before), the screen went black, and stayed bllack. Since then, even after rebooting, the screen stayed black, and still is black. More detailed, after reboting: grub2 shows up, the screen shortly wents black, the kde login background image shows up (but not the login box), and then it wents black and stays black. No keys work (like Ctrl-Alt-F1, or Ctrl-Alt-Backspace etc.) Remote login is possible, and after "telinit 3" the text console appears. With root login, issuing startx successfully starts KDE and I can work, as root. "telinit 5" again produces the black screen. This is repeatable. If I log in from the text console with my username, startx does not work, it claims it cannot remove X.org.log.old, due to insufficient permissions. Indeed , the file is owned by root. Fair enough. Now, after *once* unsuccessfully issuing startx from my user account, afterwards from root "telinit 5" does (!) work. Unfortuantely, after rebooting, the black screen is again there. grub2 kernel option "nomodeset" also helps, I can boot, no black screen. But: with nomodeset, in KDE->Configure Desktop->Display and Monitor only one screen resoultion to choose from is presented (the highest one), so it seems with "nomodeset" a different video driver is used? I'm not sure, at least there's a difference. When booting normally (with the telinit/startx trick) a long list of video modes is presented. Unfortunately, adding a grub2 kernel option "3" does *not* work. It seems that the system is indeed only booting into runlevel "3", but nevertheless the black screen appears. This behaviour seems really strange to me. Reproducible: Always Steps to Reproduce: On the affected machine here: just boot. Actual Results: grub2 screen shows, display wents shortly black (as usual), KDE login background shows, screen wents black and stays black Expected Results: Login prompt should show up -- 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.
