[Lenovo ThinkPad T420] suspend/resume failure

[Sean Brisbane]

After closing my laptop lid and allowing it to suspend to RAM, the system would not resume properly.

The visuals on the GUI returned to its previous state without any artifacts, however the mouse pointer was not working. I used a trackpad and a nipple on my T420 laptop. I left it in this state and the mouse was still dead after about 3-4 minutes. After coming back from making a cup of tea the mouse moved but did not interact with any GUI elements.

I have seens some success on previous ubuntu versions if I did a tty switch. This did not work (ctrl+alt+F1), the Unity GUI stayed visible. I then tried the sysreq triggers alt+sysreq RE and lost the mouse pointer again, but the gui stayed visible. I needed to go through the whole alt+sysreq+reisub to make the machine reboot.

WORKAROUND: Using the proprietary nvidia drivers fixes the issue:
sudo apt-get install nvidia-304-updates --install-recommends

WORKAROUND: When running the gnome desktop using metacity, there is no issue with suspend/resume with the nouveau drivers.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.14 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Upgream kernel version also shows this bug

[Sean Brisbane (s-brisbane1)]

Unrelated to this bug, I have also discovered that alt+sysreq RIE are all disabled for the mainline and trusty 'head' kernel (3.13.0-20-generic) by default:

cat /proc/sys/kernel/sysrq
176

Mentioned here:
https://bugs.launchpad.net/ubuntu/+source/procps/+bug/1025467

Also, if I suspend while the focus is on tty1 ( a text console ) rather than tty7 (GUI), the text console operates fine when I resume from pm-suspend until I switch back to tty7. At that point the system locks up again.

[Sean Brisbane (s-brisbane1)]

Hi, this is still an issue with the current trusty pre-release kernel and xorg.

[Sean Brisbane (s-brisbane1)]

Using the proprietary nvidia drivers fixes the issue, specifically.

sudo apt-get install nvidia-304-updates --install-recommends

[Sean Brisbane (s-brisbane1)]

With the nouveau drivers, and running the gnome desktop interface with compiz:

I again get a broken desktop after suspend, however I have enough control to be able to eventually get control of a dumb console tty and produce the attached dmesg output. There are obvious complaints from the nouveau drivers.

When unning the gnome desktop using metacity, there is no issue with suspend/resume with the nouveau drivers.

Sean Brisbane, as per http://download.lenovo.com/express/ddfm.html an update to your BIOS is available (1.46). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Thank you for your understanding.

Dear Christopher,

Im afraid changing the bios is beyond what I am allowed to do with this machine. It is not clear that there is any bios update relating to graphics cards or suspend/resume issues from the release notes
