Brian Candler, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.12-rc3 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Triaged => Incomplete -- 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/591699 Title: Lenovo Thinkpad x100e freezes when X blanks screen Status in “linux” package in Ubuntu: Incomplete Bug description: [Moved from #535653. I have no problem with X starting up, but only when X blanks screen] Machine is a Lenovo Thinkpad X100e model NTS5EUK: AMD Turion(tm) Neo X2 Dual Core Processor L625 stepping 02 + 2GB RAM, internal WLAN (realtek) and WWAN (Gobi 2000) cards. BIOS version reported is 1.21. Originally I had turned on the AMD virtualisation extensions in the BIOS, but I've now switched this back, so BIOS is at defaults including Config > CPU > AMD V(TM) Technology = Disabled Security > Memory Protection > Exection Protection = Enabled In #535653 I reported this problem with amd64, but I've now installed i386 from scratch with exactly the same behaviour. The laptop is connected to an Ethernet LAN and a USB CD-ROM. I have not configured wireless at all. I can reproduce the problem as follows. * Install Lucid 10.4 desktop i386 from CD * apt-get update && apt-get dist-upgrade && apt-get install openssh-server * echo "options radeon modeset=0" > /etc/modprobe.d/radeon-kms.conf * cat >/etc/X11/xorg.conf Section "ServerFlags" Option "BlankTime" "1" EndSection * reboot, let it come up to the gdm screen, then don't touch it From another machine on the same LAN, copy a large file using scp, e.g. scp ubuntu-10.04-desktop-i386.iso brian@x.x.x.x:/var/tmp/ You can also periodically check the network health from another window: while date && ssh brian@x.x.x.x hostname; do sleep 9; done What happens is: after 1 minute the X screen blanks. At this very instant, the laptop network connection freezes: the scp session stalls, and the laptop won't respond to ping. Moving the trackpoint, the screen comes back to life, but then the laptop is in a very fragile state and soon crashes. For example, pressing Ctrl-Alt-F1 usually freezes it instantly. Selecting "reboot" from the power menu will start the reboot process, but leave it frozen on a blank purple screen (possibly at the point of changing video mode again?). At this point the machine has to be hard powered off by pressing and holding the power button. Extra data points: * Login, open a terminal and type "xset s noblank" then repeat the test: the machine does NOT freeze. (I get a big "X" and a chequerboard pattern instead of the screen being fully blanked). I think this all suggests that the X blanking is the culprit, although it's not clear why the machine should stop talking to ethernet instantly but continue along in a crippled state otherwise. (Interrupts?) I did previous testing with amd64, recorded under #535653, but I have not repeated these tests with i386 yet. I found that: * leaving the screen in text mode (via ctrl-alt-F1) does not crash, even if the text mode screen blanks * installing fglrx driver didn't make a difference Also, I was able to reproduce the problem on the train this morning on battery. All of the rest of my tests have been with mains connected. There are two warning messages which flash up while the machine boots, I think they are these two lines from dmesg: [ 11.310661] shpchp 0000:00:01.0: Cannot reserve MMIO region [ 11.764446] thinkpad_acpi: Not yet supported ThinkPad detected!
