[Bug 63834] Re: suspend/resume broken on Lenovo 3000 N100
I am the original reported of this bug. As I noted in comments above, this turned out to be a bug in the suspend scripts, and not a kernel bug. I am running Hardy Heron (8.04) on my laptop, and the suspend scripts seem to have been cleaned up. I have had no problems with suspend/resume since I upgraded to Hardy. This bug can be closed as 'fixed'. -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hardy Heron 8.04 was recently released. It would be helpful if you could test the new release and verify if this is still an issue - http://www.ubuntu.com/getubuntu/download . You should be able to test your bug using the LiveCD. Please let us know your results.

Re: [Bug 63834] Re: suspend/resume broken on Lenovo 3000 N100
2 more points: 1) If some newbie is reading this: to add a parameter to the boot sequence please edit a commented line which looks like this: # kopt=root=UUID=2ea921be-867d-4841-a08c-5e91661aa5b8 ro i8042.nomux and add the parameter to it. Then execute "update-grub". Do not edit directly the grubentries. 2) When I suspend to disk, and the machine is down for a long period (about 20 mins is long enough), when the machine resumes the fan does not spin. I should mention that this happens with 2.6.20-16-generic, and probably not with 2.6.17. Do still, do not upgrade to the new kernel if you have an option. -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[EMAIL PROTECTED]:~# dpkg -l | grep susp ii uswsusp0.3~cvs20060928-6ubuntu3 tools to use userspace software suspend provided by Li [EMAIL PROTECTED]:~# s2ram -i This machine can be identified by: sys_vendor = "LENOVO" sys_product = "0768B9G" sys_version = "3000 N100 " bios_version = "61ET36WW" See http://en.opensuse.org/S2ram for details. I added the parameter i8042.nomux to grub (as explained on that page). Now I can suspend to ram (by choosing the correct option from the logout menu in KDE). When I do this 3 times at a row, the system gets stucked on resume. On the times the machine booted back up, and the was functional and I experienced no keyboard problems as explained before. Next I tried suspend to disk, which worked quite good for several times. Next test was to setup the machine to suspend to ram when I close the lid. What happens is that when I close the lid the themachine logs out of my session, and when it comes back I get the KDM menu. I log in once more, and I get a message saying that the lid is close, and it suspends once more. The machine gets into this nice loop, until I power it off by force. Right now I have 2 problems: 1) suspend to ram fails on the 3rd time. 2) closing the lid, after I instruced KDE's PowerManager to suspend on lid close even makes the machine suspend until I power it off brutally. (1) will be hard to fix, but (2) should be easy. I am not sure why it locks up, some help will be appreciated. -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 63834] Re: suspend/resume broken on Lenovo 3000 N100
Diego, it looks like you have powersaved installed. Please check if you also have uswsusp installed. I think powersave needs uswsusp to work well. If you have uswsusp installed, and you are still having problems, you might find this tutorial helpful: http://en.opensuse.org/S2ram This tutorial explains how to get s2ram working (s2ram is provided by the uswsusp package, and if installed, will be used by powersave to suspend the system to RAM). To find out which model of 3000 N100 you have: (1) if you have uswsusp installed, simply run: sudo s2ram -i (2) otherwise, you can run: sudo dmidecode -t system wiki.ubuntu.com has a page on the 3000 N100 model 0768 - B9G, if it turns you that you have that model: https://wiki.ubuntu.com/LaptopTestingTeam/Lenovo3000N100_0768 There is some information on this page about sleep/hibernate, if it turns out that you have this model (this information does not seem to apply to my model). -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 63834] Re: suspend/resume broken on Lenovo 3000 N100
I just tested it (install a new package, and edit a configuration file), and it does seem to work. Sometimes. >From my minimal tests, hibernate seems to work. Suspend to RAM is a problem: when you make the sleep from the Power Manager applet the machine comes back some of the times. When it does come back, there are some options 1) the num lock led is lighted, this means that the mouse-pad will not work. note also that the num luck is on, and to remove it, just press caps-lock twise. 2) Sometimes the machine just works perfectly. 3) Sometimes the machine just does not restore. this happens when I suspend more then once. When asked the Power Manager to suspend the machine when I close the lid, it got into a loop: each time I returned from the suspend, it suspended the machine, until it got locks. and I have to force it to power off. I also hibernated the machine now for 10 minutes and now the fan does not work. Funny, shorter hibernations (hibernate and immediately restore) it works pretty good.

[Bug 63834] Re: suspend/resume broken on Lenovo 3000 N100
I have figured out the cause of this bug, and it is not in the kernel. I have kubuntu-desktop, kpowersave, and powersaved installed and running on my laptop. The bug originates in the way that kpowersave interacts with the suspend (to RAM) scripts from hal and powersaved. I believe the following description is accurate: (1) When kpowersave detects an event that should trigger a suspend to RAM (lid closure, "sleep" button pressed, or selecting suspend to RAM from the panel applet menu), it (somehow) invokes the script: /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux (2) The /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux script checks to see which tools are available: #Other distros just need to have *any* tools installed else if [ -x "/usr/sbin/pm-suspend" ] ; then /usr/sbin/pm-suspend $QUIRKS RET=$? elif [ -x "/usr/bin/powersave" ] ; then $POWERSAVED_SUSPEND2RAM RET=$? elif [ -x "/usr/sbin/hibernate" ] ; then # Use hibernate configured for suspend-to-ram /usr/sbin/hibernate -F/etc/hibernate/ram.conf RET=$? elif [ -x "/etc/acpi/sleep.sh" ] ; then # Use acpi-support for suspend to ram /etc/acpi/sleep.sh force RET=$? elif [ -x "/usr/sbin/s2ram" ] ; then # uswsusp tools installed /usr/sbin/s2ram RET=$? elif [ -x "/usr/sbin/pmi" ] ; then /usr/sbin/pmi action suspend force RET=$? elif [ -w "/sys/power/state" ] ; then # Use the raw kernel sysfs interface echo "mem" > /sys/power/state RET=$? else # TODO: add other scripts support unsupported fi fi (3) When powersaved is installed (which includes /usr/bin/powersave), it "wins", and the powersave suspend script (/usr/lib/powersave/do_acpi_sleep) gets run (4) The do_acpi_sleep script has a section that checks to see if the s2ram executable is available: if [ -x $S2RAM ]; then echo "Executing '$S2RAM $S2RAM_OPTS'" >> $S2RAM_LOG $S2RAM $S2RAM_OPTS >> $S2RAM_LOG 2>&1 RET=$? case $RET in 127) $NOTIFY $S2RAM_NOT_SUPPORTED & ;; 126) $NOTIFY $S2RAM_FB_ONLY & ;; esac else echo "$S2RAM not found, falling back to echo." >> $S2RAM_LOG $MYECHO /sys/power/state mem RET=$? fi (5) s2ram is part of the uswsusp package, which is not required by powersaved, and so was not installed on my system. Without s2ram, the do_acpi_sleep script suspends the computer simply by echoing "mem" to /sys/power/state. On my laptop model, this causes problems on resume (the video does not get restarted properly). This is likely to cause problems for other laptop models as well. (6) The fix was to install the uswsusp package, and edit the configuration file for powersave (/etc/powersave/sleep) to set these two variables: SUSPEND2RAM_FORCE="yes" SUSPEND2RAM_VBE_POST="yes" SUSPEND2RAM_FORCE has to be set to "yes" because the s2ram program does not recognize my laptop model, and refuses to run unless forced. Also, s2ram must run in order for the second setting, SUSPEND2RAM_VBE_POST="yes", to have any effect. With these changes in place (install uswsusp, and edit /etc/powersave/sleep as above), both suspend to RAM and suspend to DISK now work nearly flawlessly on my laptop. I have verified that this solution works with both the 2.6.17 kernel (from Edgy) and the 2.6.20 (from Feisty, which I am now running). NOTE: If you are reading this and you have a Lenovo 3000 N100 laptop, the designation "3000 N100" is not a model number. There are several different model Lenovo laptops that are called 3000 N100 (mine is a model 0689-6EU). If you have a different model of Lenovo 3000 N100, you may get different results from me. -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 63834] Re: suspend/resume broken on Lenovo 3000 N100
I thought it would be better to outline the solution instead of just giving a link with my vague description. Make a new file (with sudo) in /etc/acpi/suspend.d called "04-set-cpu- scaling.sh" containing: #!/bin/sh echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Make another file (with sudo) in /etc/acpi/resume.d called "99-reset- cpu-scaling.sh" containing: #!/bin/sh echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor Also make sure to chmod ugo+x for both files. ls -l should give: -rwxr-xr-x 1 root root 81 2007-03-19 21:40 99-reset-cpu-scaling.sh -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In case it was not clear, the bug report I originally filed was about suspend to RAM, not hibernate (to disk). Hibernate worked almost all the time in 6.10 and continues to work well in 7.04 (except for the issues with ipw3945, noted above by Diego Iastrubni, which require removing and reloading the ipw3945 module). On my laptop, suspend/resume (to RAM) was broken in 6.10 and remains broken in 7.04. -- suspend/resume broken on Lenovo 3000 N100 https://bugs.launchpad.net/bugs/63834 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am not so sure this is the same bug as 63937: (1) when I try to suspend, I do *not* get any unusual sounds from the hard drive. It certainly does not sound like the disk is failing. (2) on my laptop the failure to suspend is clearly related to the wireless network -- if I bring the wireless network down then I can usually suspend the laptop successfully, but it fails when I try to resume (wake) the laptop. -- suspend/resume broken on Lenovo 3000 N100 https://launchpad.net/bugs/63834 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
