| Fedora Test Days | |
|---|---|
| |
| Power Management | |
| Date | 2011-09-29 |
| Time | all day |
| Website | QA/Fedora_16_test_days |

| Mailing list | test |
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 ...
- Development - Jaroslav Škarvada (jskarvad) / PowerManagement SIG
- Quality Assurance - Jan Ščotka (jscotka)
Note: jskarvad will be available at least from 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.
Prerequisite for Test Day[edit]
- PM Test Day LiveCD (md5sum: f470deed996574ab101d75b9eb5bf5c7) or an updated Fedora 16 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.
- 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, tuned profiles. 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]
- 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
- Install the PM Test Day support package by:
# yum install http://jskarvad.fedorapeople.org/pm-test-day-repo/pm-test-day-2-1.fc16.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
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 |
| Tuned basic | Tests tuned-adm (tuned) basic functionality. | All | 5 minutes |
| Tuned disabled idle | Measures power consumption of machine in active idle with tuned disabled. | Laptops only | 15 minutes |
| Tuned powersave idle | Measures power consumption of machine in active idle with tuned laptop-battery-powersave profile. | Laptops only | 15 minutes |
Known Bugs / Workarounds[edit]
The following are the known bugs and workarounds. You do not need to report them, because the problems are known and most fixes are already in updates-testing repo.
- upower < 0.9.13-1 has unresolved symbol (g_unix_signal_add_watch_full) due to glib API change and doesn't start which cause fail of the pm-powersave test case. Upgrade to upower-0.9.13-1 (from pm-test-day repo) or newer by:
# yum update upower
- Then logout/login or start upower by hand:
# /usr/libexec/upowerd
- If you are using the latest LiveCD / USB (20110928 or newer) this workaround have been already installed for you.
- If the OSD in test case pm-powersave is not shown, patch the pmtd-osd by following command:
# echo 'echo "$STR" >> /tmp/pmtd-osd.log' >> /usr/bin/pmtd-osd
- and than read the OSD messages from /tmp/pmtd-osd.log
- If your system doesn't have /proc/acpi/battery/BAT0 directory but has there other sub-directory (e.g. BAT1) and you are going to run the Tuned disabled idle, Tuned powersave idle test cases, you will need to update your pm-test-day package to version 2.1-1 or newer by:
yum update pm-test-day
- If you cannot see the pm-test-day update, try to clear your yum caches by:
yum clean all
- If you are running from the LiveUSB, the Tuned disabled idle, Tuned powersave idle test cases can hang your computer. It is caused by the cache clear command - the reason why this happen is currently unknown. To workaround this, open /usr/bin/pmtd-measure script in any text editor and comment (by #) the line with the call of clear_caches function. With the pm-test-day-2-1 package it is the line 76, with the pm-test-day-2.1-1 package it is the line 95.
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 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.
Long comments[edit]
- ↑ Test passed, but I encountered RHBZ #742061 that was related to wlan. I had to install abrt-cli in order to report it, because the abrt-gui didn't handle it. All comments about it will be handled to abrt guys.
- ↑ My system doesn't suspend with docking station because GNOME3 is brain-damaged. RHBZ #719679, with patch here. Since this wastes power, I'm reporting it here for powersaving test day even though it is because "the designers wanted this behavior".
- ↑ Didn't hibernate, but a message AC POWER printed instead of it (like AC cable plugged in, but I didn't do anything with the cable). Run from LiveUSB.
- ↑ Didn't suspend when the lid was closed. But it works after reboot Before the reboot, PM features of the desktop were kind of missing. The battery icon was not there, no brightness control in "gnome-control-center power". This happens to me from time to time on regular basis, maybe some problem with ACPI. But I cannot reliably reproduce.
- ↑ (upowerd:5277): UPower-WARNING **: Failed to acquire org.freedesktop.UPower (upowerd:5277): UPower-WARNING **: Could not acquire name; bailing out, not working
- ↑ Some profile caused, that mouse was disabled and not working, tested with: for foo in
tuned-adm list 2>&1 |egrep "^- " |sed "s/- //"; do tuned-adm profile $foo; sleep 1; tuned-adm active; done, after investigation I found that spindown-disc caused the problem with mouse - ↑ Gnome detected it properly but no OSD is shown and no file /tmp/pmtd-osd.log is created (not exists). Neither restarting upowerd does not solve this problem. However, when was battery low, OSD was shown.
- ↑ Increasing is not properly showed by Gnome. It works only from start to first half. In half of progress bar, backlight is in full state and increasing causing progress bar change but no backlight. When decreasing, other thing happens - backlight is set lower than should be and immediately light up (to correct level) - so it's causing unpleasant flashing.
