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.
On site event
You can attend this event online or personally: http://fedora.cz/udalosti/den-otevrenych-dveri-v-red-hatu/

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 at least during 10:00 - 22:00 (UTC+2) on #fedora-test-day, #fedora-power, #fedora-devel, otherwise he will be on e-mail with non guaranteed response time. He will be also available on site in Red Hat Brno Office at least during 13:00 - 19:00.

Prerequisite for Test Day[edit]

  • PM Test Day LiveCD 20120404-1-i686 (md5sum:72f4d13fe18f7fc8ce7ba4d8f6fdc85d) or PM Test Day LiveCD 20120404-1-x86_64 (md5sum:16cac224a03a4467756360cedf6d655f) or an updated Fedora 17 pre-release or you may get nightly composed LiveCD.
    • It is possible to convert the LiveCD into LiveUSB by following the How_to_create_and_use_Live_USB instructions. If you convert the LiveCD into LiveUSB it is recommended to create on USB another primary partition that will serve as swap. This is useful for pm-hibernate test case.
    • If you attend the event on-site in Red Hat Brno office, there will be prepared bootable USB flash disks, thus you only need to bring your hardware there.
  • Your hardware profile uploaded to Smolt according to these instructions
  • Optional: account on fedoraproject.org if you plan to upload the pm-utils bugreport file. If you do not have one and you do not plan to get it, you can still attend the test day - there are instructions in the appropriate test case(s) bellow how to handle such situation.

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]

It is focused especially on suspend, hibernate, power-consumption, LCD brightness control and our new 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:
    # yum install http://jskarvad.fedorapeople.org/pm-test-day-repo/pm-test-day-3-1.fc17.noarch.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

Known Bugs / Workarounds[edit]

Currently there is a bug in software rendering used by Gnome 3 that affects several users (mostly on older hardware):

  • RHBZ #808710 - llvmpipe driver doesn't render correctly on Dell Inspiron Mini 10

If you are affected by this bug and your desktop graphics is broken, try to switch to gnome-fallback mode by:

    • Press Alt + F2
    • Write gnome-terminal and confirm with Enter.
    • Run the following commands in the terminal:
      $ gsettings set org.gnome.desktop.session session-name 'gnome-fallback'
      $ pkill gnome

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 2 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 1 minutes
Lid close Tests system reaction to lid close. Laptops 1 minutes
Backlight control Tests LCD backlight control. Laptops 1 minute
Tuned Tests tuned-adm (tuned) basic functionality. All 5 minutes
Tuned disabled idle Measures power consumption of machine in active idle with tuned disabled. Laptops or users with wattmeter 15 minutes
Tuned powersave idle Measures power consumption of machine in active idle with tuned laptop-battery-powersave profile. Laptops or users with wattmeter 15 minutes

Test Results[edit]

If you have problems with any of the tests, report a bug to Bugzilla usually for the component pm-utils, 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 kelto 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.

Long comments[edit]

  1. While changing the LCD backlight power, after repeatedly pressing the keys in either of the edges of the light power settings and then going back the other direction (to the opposite light power edge), the backlight power skips back sometimes.
  2. Tuned service start stopped by SELinux. Bug809294 Fixed on selinux-policy-3.10.0-110.fc17.noarch
  3. Booted from LiveUSB with 6GB swap partition on it. No problems resuming from hibernation. I only had to manually choose to boot from the LiveUSB again.
  4. After hibernate during wake up phase was restoring desktop on the firrst console (F1) not correctly (incomplete decoration of windows) and blocking the keyboard (I can only switch the konsole (Fx), but not any othes actions.)
  5. the system tried to boot from harddrive, not from the liveusb, and I was unable to change that (only after booting from harddrive and rebooting again, the multiboot menu got accessible again - but the hibernated stated was gone, obviously)
  6. I got some SELinux denials (bugs #809836 #809837 #809838)
  7. Works after changes in gnome config: gconftool-2 --set --type boolean "/apps/gnome-power-manager/backlight/enable" false;sudo -u gdm gconftool-2 --set --type boolean "/apps/gnome-power-manager/backlight/enable" false
  8. at one touch of backlight down, steping to min backlight, and at one touch backlight up, steping to max backlight(time of stepping aproximatly 4 seconds)
  9. Power consumption was too high (14w-17w), to fix it i used flags: i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 pcie_aspm=force , now it's 9w-12w
  10. 3xOK,1xFail hibernating from Personal Menu - abrt redirected to RHBZ #713687 , but I am not sure whether this is the right place. I believe it has got something to do with changing number of displays between hibernate and wake-up.
  11. was having syntax errors in the script and I had to uninstall an install the pm-test-day-3-1.fc17.noarch package again to get updated version. In such situations version shuld probably bump.
  12. Probably in first tuned-powersave measurement was affected by the running firefox in the background, second retest without firefox showed some decrease in power comsumption.But as the difference is approximately only 01% I would blame it on statistical error of the measurement.
  13. I performed two measurements one after another and got two slightly different results: 5.979 Wh (14.837 V), 6.657 Wh (14.599 V); the entry in the table represents the average
