I have this problem with a Toshiba Portegé Z930 and Ubuntu 12.04. But I get instead a black screen with a mouse cursor and a console cursor blinking. After pressing 2 or ENTER, lightdm starts again.
I leave a "tail -f /var/log/Xorg.0.log" on the tty1 before pressing 2 or ENTER, and then I press it, and I can see the crash log. I'm attaching it. #105 workaround does NOT fix the problem for me. Removing the /etc/init /plymount-splash.conf does, however. ** Attachment added: "Black screen before pressing ENTER - Toshiba Portegé Z930" https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/532047/+attachment/3453842/+files/2012-12-05%2018.15.59.jpg -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/532047 Title: Plymouth text-mode splash causes X to crash on first run due to shared tty7 Status in X.Org X server: Invalid Status in “plymouth” package in Ubuntu: Fix Released Status in “xorg-server” package in Ubuntu: Invalid Bug description: Binary package hint: plymouth Lucid adopted the Plymouth graphical splash service that uses the Kernel Mode Setting (KMS) facilities to provide a flicker-free graphical splash during start-up. For older video chipsets and drivers (e.g. intel i815) that *do not* support KMS plymouth falls back to using a text console (using the text plugin). It attaches to tty7 and outputs Linux terminfo control codes to draw a colour progress-bar at the bottom of the display. There is an unfortunate interaction between plymouth and X. X also uses tty7. When the X/GDM log-in screen appears for the first time plymouth is still running. A script triggers a quit message to the plymouth daemon. It seems that plymouth is waiting for either the "2" key or "Enter" key to be pressed, whereupon a SIGQUIT (signal 3) is sent to tty7. This causes both plymouth *and* X to terminate. So, if a password contains "2" or the user logs in by pressing "Enter" after typing their password, the user experience is that X 'crashes' (however, gdb reveals that X receives SIGQUIT). Some stray plymouth control codes can be witnessed on tty7 if X is stopped and tty7 console is on-screen. Upstart (/sbin/init) then restarts gdm (which launches X) and the second session performs correctly. *** A temporary workaround is to disable the plymouth-splash upstart job *** sudo mv /etc/init/plymouth-splash.conf /etc/init/plymouth- splash.conf.disabled To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/532047/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
