Hello, tested with 12.04.4 stock image on 201109-9790 (BIOS A04) I think we can narrow down this issue to nouveau itself, it works fine with the nvidia-331-update proprietary driver
This system can be suspended with nouveau, but X will crash on resume. Many EE could be found in the attached log. Steps for reproduce this bug: 1. Install 12.04.4, boot to desktop 2. Suspend it by using the "suspend" option in system menu 3. Press the power button to wake it up Expected result: * Suspend/resume works fine on this system Actual result: * System suspended * On resume, you will see the desktop instead of the unlock dialog, and it freezes, the cursor is the only responding thing. A moment later, you will see the login screen, but it freezes again when you try to log in. Since the proprietary driver works, blocker tags will be removed ** Attachment added: "Xorg.0.log-12.04.4" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1182296/+attachment/3998749/+files/Xorg.0.log.old ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags removed: blocks-hwcert blocks-hwcert-enablement ihv-nvidia ** Summary changed: - [Dell Precision T7600] System fails to resume from suspend + [Dell Precision T7600] System fails to resume from suspend with nouveau driver ** Summary changed: - [Dell Precision T7600] System fails to resume from suspend with nouveau driver + [Dell Precision T7600][NVIDIA NVS300] System fails to resume from suspend with nouveau driver ** Changed in: linux (Ubuntu) Importance: High => Medium ** Package changed: linux (Ubuntu) => xserver-xorg-video-nouveau-lts- saucy (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1182296 Title: [Dell Precision T7600][NVIDIA NVS300] System fails to resume from suspend with nouveau driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau-lts-saucy/+bug/1182296/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
