Martin Konopka, thank you for testing Trusty. Does this problem not occur in a release prior to Trusty?
As well, could you please provide the missing information following https://wiki.ubuntu.com/DebuggingKernelBoot ? ** Tags added: saucy trusty ** Package changed: xorg (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Medium => High ** Summary changed: - HP ZBook, live ubuntu 13.10: freezes (a video driver problem) + HP ZBook, live ubuntu 13.10: freezes -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1255104 Title: HP ZBook, live ubuntu 13.10: freezes Status in “linux” package in Ubuntu: Incomplete Bug description: machine: HP ZBook 15 (Intel Core i7 4700MQ Haswell, NVIDIA Quadro K1100M 2GB, 1920 x 1080 display) system: ubuntu 13.10 desktop, 64-bit, live DVD (md5 sum OK) I boot from the live DVD. The boot goes fine. Then I decide to try the ubuntu (not to install). I go to the search in the left upper corner, type "terminal". I open the terminal. After a while the desktop environment almost completely freezes. I can only move the touchpad pointer. I can also switch to the console (Alt Ctrl F1) and then back (Alt F7). The desktop responds after this switch but its reactions and colours are strange and it is unusable. I guess a problem with a video driver. I am not sure which one because there are two graphics processors inside (one is an embedded Intel HD Graphics 4600, the other is the NVidia, see above). However, I have similar problems when I insert the DVD into an old computer: 1st generation Intel i7, without an embedded graphics, with two dual cards GeForce GTX295 (4 GPUs together). The machine runs fine older Ubuntu and Mint releases.
