After upgrading my Asus laptop to Ubuntu 15.10 I got dumped to black screen with a flashing cursor.
To fix this I had to: 1. run "sudo dpkg --configure -a" to finish installing packages that were already downloaded 2. run "sudo apt-get install --reinstall resolvconf" - because apt told me resolvconf was broken 3. run "sudo dpkg-reconfigure lightdm" (and pick lightdm again) and then reboot (to get a graphical desktop back) 4. edit /etc/bumblebee/bumblebee.conf and change KernelDriver, LibraryPath and XorgModulePath to point to the newer NVidia driver Ubuntu had installed, then reboot (to get bumblebee's primusrun command working again) Not the greatest upgrade experience but its all working now. Of course don't do the above unless you read a little and know what these do, or have reason to believe that these will solve problems you actually have. I'm sharing the list of things in case they give you some hints to solving similar problems. My specs: Asus X550L laptop, NVidia GeForce 840M graphics. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1492764 Title: [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0) To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1492764/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
