[Touch-packages] [Bug 1579278] Re: Keep powersave CPU frequency scaling governor for CPUs that support intel_pstate
On my Dell XPS 13 (i7-6500U) the only governors available are performance and powersave. Ubuntu 16.04 seems to set this always to 'powersave' for me. This causes the CPU to clock down to 300-400Mhz when idle. Unfortunately it's not clocking up again when under load sometimes. Setting the governor to performance 'fixes' it. I don't know if this is *this* issue or another one, so happy to open a new issue if you prefer. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to sysvinit in Ubuntu. https://bugs.launchpad.net/bugs/1579278 Title: Keep powersave CPU frequency scaling governor for CPUs that support intel_pstate Status in linux package in Ubuntu: Invalid Status in systemd package in Ubuntu: Fix Released Status in sysvinit package in Ubuntu: Invalid Status in linux source package in Xenial: Invalid Status in systemd source package in Xenial: Invalid Status in sysvinit source package in Xenial: Triaged Bug description: Hi, With the new Ubuntu archive servers, we saw constantly high load and after some tinkering, we found that it was mostly CPUs being woken up to see if they should enter idle states.

[Touch-packages] [Bug 1482303] [NEW] python 3.4.0's argparse ignores subcommand
Public bug reported:
Hi,
take this simple example:
```
#!/usr/bin/env python3
import argparse
def do_default(options):
print(default)
def do_build(options):
print(build)
if __name__ == '__main__':
parser = argparse.ArgumentParser()
subparsers = parser.add_subparsers()
parser.set_defaults(func=do_default)
build = subparsers.add_parser('build')
build.set_defaults(func=do_build)
options = parser.parse_args()
options.func(options)
```
On Ubuntu 14.04, without parameters it errors for missing command and
with the parameter build it prints default, so the subcommand gets
ignored somehow.
If running this on ubuntu 15.04, it works as expected: Without
parameters, it prints default. With the parameter build it prints
build.
I couldn't track that to any upstream bug report, but it seems like a
issue was fixed and the fix needs to get backported to ubuntu 14.04.

[Touch-packages] [Bug 1390625] Re: mouse cursor gets corrupted
The #7 workaround for Xubuntu 14.10 works for me. A few weeks ago I added a new user to Xubuntu, and that user didn't get the mouse corruption at all. But they do now - for the past few days.
