| {{result|fail}}<ref group="long">Laptop suspended on lid close and resumed on lid open. However: (1) If the VGA-out was plugged into an external monitor when the lid was closed, the laptop did not suspend. (I expect this is by design.)  But ( {{bz|692759}} ) if the laptop had been booted with VGA plugged in, then if I pull out the VGA cable and then wait a few seconds and shut the lid then wait and open it again, on resume the laptop's screen is blank. I can't bring it back with Fn+F5 which is the normal video pipe switch key combination. I have to manually plug the VGA adapter back in (laptop panel stays black) and *then* when I go Fn+F5 I can cycle through the various pipe modes and get the laptop screen back again.  (2) {{bz|692760}} The keyboard layout (manually set with setxkbmap) was not restored correctly on resume. (3) {{bz|684415}} I got an AVC denial on wpa_supplicant on resume.</ref>
| {{result|fail}}<ref group="long">{{bz|692761}} Pressing Fn+F6/F7 to adjust laptop panel brightness pops up the OSD but does not change the brightness setting if the laptop was booted with an external monitor plugged into the VGA port, even if the plug is later removed.  (If I boot without an external monitor connected then it works fine.)  If I booted with an external monitor plugged in, powertop reports the panel power setting at the same percentage as the OSD displays, but the brightness never visibly changes. Booting with an external monitor plugged in seems to permanently disable the brightness controls until reboot. ([https://bugzilla.gnome.org/show_bug.cgi?id=646404 GNOME BZ #646404] Also, if I keep tapping Fn+F6/F7 quickly, the GNOME widget seems to lose keypress events (it can only handle them at a certain rate, and takes maybe 100ms to respond to each press), which makes the widget response feel sluggish and sloppy..)</ref>
| {{result|warn}}<ref group="long">In Tunables tab, if you keep hitting the down arrow key, then the cursor goes off the bottom but it doesn't scroll the display to show the further entries on the list [also reported by somebody else above].  Also what on earth does "Bad" and "Good" mean? This tool is quite non-intuitive.</ref>
| {{result|warn}}<ref group="long">Running "gnome-control-center power" says: "Error getting primary device: GDBus.Error:org.gnome.PowerManager.Failed: There is no primary device to reflect system state (don't show any UI)".  However "powertop --calibrate" seems to run to completion fine.  It couldn't set the backlight during calibration because I had an external monitor connected earlier as specified above.  A bigger problem though is that plugging in power again after the calibration process (I think -- or maybe the calibration process itself?) managed to shut down the USB ports and I had to unplug and re-plug the mouse to get it working.  Is this expected?</ref>

| {{result|fail}}<ref group="long">{{bz|692765}} "tuned-adm laptop-battery-powersave" worked, but any subsequent usage of tuned-adm failed.  e.g. "tuned-adm spindown-disk" hangs on "Stopping ktune (via systemctl)". I waited a minute, hit Ctrl-C, and it said "Stopping ktune (via systemctl)" again but this time said "[OK]" then "Switching to profile 'spindown-disk'" and then hung on "Starting ktune (via systemctl)". After Ctrl-C I heard my speaker click and it hung again on "Starting ktune (via systemctl)". Waiting another minute and pressin Ctrl-C again drops me back to the command prompt.  (Actually it looks like trying any parameter after the first call to tuned-adm results in the same behavior, i.e. it works once only.)</ref>

Mailing list test


Can't make the date?
If you come to this page after the test day is completed, your testing is still valuable, and you can use the information on this page to test, file any bugs you find at Bugzilla, and add your results to the results section. If this page is more than a month old when you arrive here, please check the current schedule and see if a similar but more recent Test Day is planned or has already happened.

What to test?[edit]

Today's instalment of Fedora Test Day will focus on Power Management

Who's available[edit]

The following cast of characters will be available for testing, workarounds, bug fixes, and general discussion ...

Note: jskarvad will be available during 09:00 - 14:30 (UTC+1) on #fedora-test-day, #fedora-power, #fedora-devel, otherwise he will be on e-mail with non guaranteed response time.

Prerequisite for Test Day[edit]

Typing convetions[edit]

In the following text commands that needs to be run as root are prefixed by #, e.g.: 

# id

means to run id command under the root account. Commands prefixed by $ do not need to be run under the root account.

How to test?[edit]

Focus on pm-utils, powertop, tuned. Some test cases are only for laptop users and it is signalled in test case description field. If you do not have laptop just skip them. You can also skip other test cases (e.g. if you do not have enough time). In this case just leave the columns for skipped test cases blank. Please note that your report will be still valuable even if you do not finish all test cases. The procedure:

  • Run test cases bellow.
  • Report results to the result table.

Prepare your system[edit]

If you are using our PM Test Day LiveCD, please skip the following steps, because everything is already prepared for you.
  1. Install the public key (in case you would like to verify the PM Test Day support package, otherwise you can skip this step because the public key will be installed automatically with the PM Test Day support package in the next step): 
    # rpm --import http://jskarvad.fedorapeople.org/RPM-GPG-KEY-pm-test-day
  2. Install the PM Test Day support package by:
    • For 64 bit: 
      # yum install http://jskarvad.fedorapeople.org/pm-test-day-repo/pm-test-day-1-2.fc15.x86_64.rpm
    • For 32 bit: 
      # yum install http://jskarvad.fedorapeople.org/pm-test-day-repo/pm-test-day-1-2.fc15.i686.rpm
    • This procedure will also install the public key which will be then used for verification of packages from the PM Test Day repo.

Finally make sure you have all current updates (and temporal fixes) installed by: 

# yum update

Test Cases[edit]

Testcase Description Target Approx. time required
pm-suspend Tests suspend / resume via pm-utils. All 2 minutes
pm-hibernate Tests hibernate / resume via pm-utils. All 5 minutes
pm-bugreport Tests pm-utils bug-reporting functionality. All 2 minutes
pm-powersave Tests detection of AC / battery (upower functionality) and pm-powersave reactions to power source changes (pm-utils). Laptops only 2 minutes
Lid close Tests system reaction to lid close. Laptops only 2 minutes
Backlight control Tests LCD backlight control. Laptops only 1 minute
PowerTOP 2.x basic Tests PowerTOP 2.x basic functionality and UI consistency. All 5 minutes
PowerTOP 2.x PE engine Tests PowerTOP 2.x power estimation engine. Laptops only 60 minutes
PowerTOP 2.x suggestions Tests PowerTOP 2.x tunables. All 5 minutes
Tuned basic Tests tuned-adm (tuned) basic functionality. All 5 minutes
Tuned psave idle Measures energy consumption of machine in active idle with tuned laptop-battery-powersave profile. Laptops only 15 minutes
Tuned psave load Measures test duration / energy consumption of machine under load with tuned laptop-battery-powersave profile. All, laptops preferred 5 - 30 minutes
Tuned perf idle Measures energy consumption of machine in active idle with tuned throughput-performance profile. Laptops only 15 minutes
Tuned perf load Measures test duration / energy consumption of machine under load with tuned throughput-performance profile. All, laptops preferred 5 - 30 minutes

Known Bugs[edit]

Already fixed[edit]

If you update your system from the PM Test Day repo or PM Test Day LiveCD, you shouldn't encounter the following bugs:

  • RHBZ #684854 - It is about missing tab bar in PowerTOP 2.x.
  • RHBZ #663995 - It is about SELinux AVCs during suspend / hibernate.
  • RHBZ #689113 - It is about AVC on EEEPCs when laptop-battery-powersave profile is in use (write access to cpufv).

Currently unfixed[edit]

You can still encounter the following bugs:

  • RHBZ #690177 - It is about the tuned profiles switching and tuned starting/restarting - it can take "forever".
    • Currently there is no known workaround, probably something related to the systemd.
  • AC ONLINE / BATTERY OSD notifications are not shown when booted from the LiveCD.
    • It is the LiveCD test case problem, workaround: 
      # xhost +; sed -i 's|^#!/bin/bash$|\0\n\nexport DISPLAY=:0|' /usr/bin/pmtd-osd
    • Or substitue xosd command in pmtd_osd by logger command and check your logs instead of OSD.
  • The PM Test Day Live CD doesn't seem to support resume from hibernate using the swap that is located on the LVM.
    • You need to use swap partition outside the LVM or F15 installed on your harddrive.

Test Results[edit]

If you have problems with any of the tests, report a bug to Bugzilla usually for the component pm-utils, or powertop, or tuned. If you are unsure about exactly how to file the report or what other information to include, just ask on IRC and we will help you. Once you have completed the tests, add your results to the Results table below, following the example results from the first line as a template. The first column should be your name with a link to your User page in the Wiki if you have one, and the second should be a link to the Smolt profile of the system you tested. For each test case, use the result template to enter your result, as shown in the example result line. bugreport.txt will be generated by test case pm-bugreport, instructions for uploading are included in this test case. The bugreport.txt gives us valuable information about your HW / SW configuration and debug log of your last suspend / hibernate process. If you ran the tuned profile tests, please write the results to the second table.

Please note there are two tables.

  1. ↑ suspend worked, resume mostly worked but CD could no longer be read (many SQUASHFS errors) making further efforts fruitless
  2. ↑ hibernate was fine, but resume resulted in a kernel panic. mem = 3054624, swap = 5119996, so perhaps a factor?
  3. ↑ inability to read CD after resume made it impossible to upload a file that included the pm bugreport

Long comments[edit]

  1. ↑ Works when on battery, but fails when on docking station (it does nothing when lid is closed and it switches monitor resolution when lid is opened)
  2. ↑ suspended successfully with power plugged in, but when I subsequently closed the lid while running on battery, the laptop did not suspend - inability to read CD after initial resume suspected culprit
  3. ↑ When I set "SATA link pm[...]" , "NMI watchdog[...]" , "VM writeback timeout" , "Audio codec pm" to Good, exit powertop and start it again then I cannot revert mentioned Tunables to Bad
  4. ↑ After wake-up the screen remains black, but it seems to work as i can hear system sounds and see drive activities when i type around on the keyboard
  5. ↑ It will successfully suspend once, subsequent suspends fail with in dmesg: legacy_suspend(): pnp_bus_suspend+0x0/0x6a returns 28 PM: Device 00:0a failed to suspend: error 28
  6. ↑ NOTE: ( RHBZ #692756 ) In general this laptop is unable to shutdown or reboot from the commandline. "poweroff" or "shutdown" goes all the way through the shutdown process but at the final step when it says it is powering down, it just sits there with the cursor blinking.
  7. ↑ Laptop suspended on lid close and resumed on lid open. However: (1) If the VGA-out was plugged into an external monitor when the lid was closed, the laptop did not suspend. (I expect this is by design.) But ( RHBZ #692759 ) if the laptop had been booted with VGA plugged in, then if I pull out the VGA cable and then wait a few seconds and shut the lid then wait and open it again, on resume the laptop's screen is blank. I can't bring it back with Fn+F5 which is the normal video pipe switch key combination. I have to manually plug the VGA adapter back in (laptop panel stays black) and *then* when I go Fn+F5 I can cycle through the various pipe modes and get the laptop screen back again. (2) RHBZ #692760 The keyboard layout (manually set with setxkbmap) was not restored correctly on resume. (3) RHBZ #684415 I got an AVC denial on wpa_supplicant on resume.
  8. ↑ RHBZ #692761 Pressing Fn+F6/F7 to adjust laptop panel brightness pops up the OSD but does not change the brightness setting if the laptop was booted with an external monitor plugged into the VGA port, even if the plug is later removed. (If I boot without an external monitor connected then it works fine.) If I booted with an external monitor plugged in, powertop reports the panel power setting at the same percentage as the OSD displays, but the brightness never visibly changes. Booting with an external monitor plugged in seems to permanently disable the brightness controls until reboot. (GNOME BZ #646404 Also, if I keep tapping Fn+F6/F7 quickly, the GNOME widget seems to lose keypress events (it can only handle them at a certain rate, and takes maybe 100ms to respond to each press), which makes the widget response feel sluggish and sloppy..)
  9. ↑ In Tunables tab, if you keep hitting the down arrow key, then the cursor goes off the bottom but it doesn't scroll the display to show the further entries on the list [also reported by somebody else above]. Also what on earth does "Bad" and "Good" mean? This tool is quite non-intuitive.
  10. ↑ Running "gnome-control-center power" says: "Error getting primary device: GDBus.Error:org.gnome.PowerManager.Failed: There is no primary device to reflect system state (don't show any UI)". However "powertop --calibrate" seems to run to completion fine. It couldn't set the backlight during calibration because I had an external monitor connected earlier as specified above. A bigger problem though is that plugging in power again after the calibration process (I think -- or maybe the calibration process itself?) managed to shut down the USB ports and I had to unplug and re-plug the mouse to get it working. Is this expected?
  11. ↑ RHBZ #692765 "tuned-adm laptop-battery-powersave" worked, but any subsequent usage of tuned-adm failed. e.g. "tuned-adm spindown-disk" hangs on "Stopping ktune (via systemctl)". I waited a minute, hit Ctrl-C, and it said "Stopping ktune (via systemctl)" again but this time said "[OK]" then "Switching to profile 'spindown-disk'" and then hung on "Starting ktune (via systemctl)". After Ctrl-C I heard my speaker click and it hung again on "Starting ktune (via systemctl)". Waiting another minute and pressin Ctrl-C again drops me back to the command prompt. (Actually it looks like trying any parameter after the first call to tuned-adm results in the same behavior, i.e. it works once only.)
  12. ↑ At first it told that I had charge for 10 hours but that isn't true. Later it told me that I've got about 1,5 h which is most likely correct
  13. ↑ It suspends fine but after the resume there are a lot of SQUASHFS errors and the system starts behaving strangely, e.g. a lot of input/output errors. Works OK if booted from the HDD and not from the LiveCD/USB.
  14. ↑ Some tunables can not be changed back to BAD: SATA Link PM, NMI watchdog, Power aware CPU scheduler, VM writeback, Audio Codec power management, Wake On LAN status on interfaces, ondemand cpufreq governor.
