Summary ======= I think I am affected by this same bug, I have all the above systems and get hard lockups with Linux kernel 3.16 every 5 - 15 minutes.
Attempted upgrading to (x)ubuntu 14.10 to see if this improved stability and laptop crashed so badly during the upgrade that it broke grub and had to be recovered with ubuntu boot-repair. This alowed the system to boot and I was able to complete configuration with dkpg --configure -a --pending System still crashes every few minutes when running (x)ubuntu 14.10 and about 50% of the time crashes before even reaching the login screen. If I'm lucky attempting to swich VCs will resolve things but the system always crashes eventually and has to be powered off by holiding the power button for 10 seconds or via the magic sysreq key. No other key cominations work. Hardware ======== I also have an Asus laptop with an Nvida card which is what led me to this bug report, the following hardware is present: * Laptop model Asus G750JS (ASUS-NotebookSKU) * GK104M [GeForce GTX 870M] * 4th Gen Core Processor Integrated Graphics Controller (i915 - not used) * BCM4352 802.11ac Wireless Network Adapter * QCA8171 Gigabit Ethernet BIOS/DMI information ================== I tried flashing the latest BIOS from (http://www.asus.com/Notebooks_Ultrabooks/ASUS_ROG_G750JS/HelpDesk_Download/) but it didn't fix anything. Running the commands listed above gives: $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date G750JS.208 07/17/2014 Driver info ======== This problem occurs with both the nouveau and nvidia drivers: rc nvidia-331-updates 331.113-0ubuntu0.0.4 (removed by "additional drivers" application) ii xserver-xorg-video-nouveau 1:1.0.11-1ubuntu2 Workaround ========== This configuration is rock solid on kernel 3.13. I was able to boot to a previously installed kernel (3.13.0-44-generic) and the system performs as expected and is stable. Debug info ========= I was able to take a photo after the ubuntu system upgrade crashed (attached). The system has been generating a bunch of problem reports too so I've been clicking the submit button. Happy to rovide futher info or try a few experiments to get this resolved. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1371401 Title: randomly freezing Status in xorg package in Ubuntu: Incomplete Bug description: Seems to be related to https://bugs.launchpad.net/ubuntu/+source /nvidia-prime/+bug/1220426 ASUS N550JK Touchscreen nVidia 343 graphics on Geforce GTX 850M Latest Linux kernel 3.16, Ubuntu 14.04 with xfce Screen can be unfrozen by doing ctrl+alt+f6 and then back with ctrl+alt+f6.
