I don't have such a device, so I'm afraid I either need someone with such a device to debug this, or get ssh access to an affected machine. As a first step, please install valgrind, and run this:
sudo killall upowerd; sudo valgrind --leak-check=full -- /usr/lib/upower/upowerd -v 2>&1 | tee /tmp/upower.log There should be a lot of text at the initialization, and then I expect some regular updates for the wireless keyboard/mouse batteries. These will hopefully go along with some valgrind leak traces. It should be sufficient to just let that run for maybe 10 minutes, then press Control-C, and attach /tmp/upower.log here. Thanks! ** Summary changed: - upowerd is using too much memory + upowerd leaks memory with Logitech universal receiver ** Changed in: upower (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upower in Ubuntu. https://bugs.launchpad.net/bugs/757551 Title: upowerd leaks memory with Logitech universal receiver Status in “upower” package in Ubuntu: Incomplete Bug description: Binary package hint: upower I currently have 36 days of uptime on my laptop (using suspend a lot) and over time, I've noticed that the upowerd process got to the top of the list in terms of memory usage by claiming 1GB+. I can manage with this situation since I have 6GB of physical memory, but I'm sure that people with less in their laptops will not be so fortunate.
