[Touch-packages] [Bug 1164016] Re: restore type-ahead find

2019-02-01 Thread Chris Billington
I don't know how long it will take, but in the meantime Ubuntu could
ship the patch maintained by the Arch community:

https://aur.archlinux.org/cgit/aur.git/tree/nautilus-restore-
typeahead.patch?h=nautilus-typeahead

It looks like this patch is kept up to date pretty well. There is a
similar patch for gtk3 to make the file chooser dialog have type-ahead.

It's the best of both worlds, since you can still tap ctrl-f to search.

Whilst it would be nice for the Nautilus devs to upstream the patch or
for there to be a dialog about what kind of patch they might accept (if
any), in the meantime distros can include the patch, there is little
downside since the patch is maintained and not bit rotting. Canonical
would not be committing themselves to maintaining it by including it.

  Now when you type in a Nautilus window, Nautilus immediately performs
  a search in the current directory and all its subdirectories.  I
  personally find this annoying.  If I want to search, I'll click the
  search icon.  Often I'm looking at a long directory listing and simply
  want to jump to a certain point in it, and type-ahead find works great
  for that.

  Would Ubuntu consider patching type-ahead find back in?

[Touch-packages] [Bug 1164016] Re: restore type-ahead find

2019-02-01 Thread Chris Billington
I don't think it's true that an option is always good. I think software
should endeavour to have decent default options, and if multiple use
cases can be accommodated without an option, then that is preferable.

But you're right, a recursive search with ctrl-f vs typeahaed with
simple typing would accomplish what everyone wants without an option.

I'm using the 'search in current folder only' setting in order to make
the search more like typeahead, but this has the downside that I have to
go into the settings to do an actual recursive search. In reality,
recursive search is useful, and I want to use it, but it's different to
typeahead and it's a shame I have to pick one or the other.

Ideally for me would be typing is just going to select things similarly
to the old typeahead behaviour, and ctrl-f would do a search, either in
the current folder or recursively depending on a checkbox that would
ideally be in the main interface next to the search box rather than in
the settings menu - since one often wants one or the other, it's not
really an all-time preference.

I do think things will eventually go back this way. There is currently
wasted effort trying to make search meet the requirements of type-ahead,
whereas this would be unnecessary if typeahead existed too. Search is
becoming a bit of a frankenstein trying to be both, with returning items
from the current folder first, and having the search-in-current-folder-
only setting being global. It should just be search - features should do
one thing each instead of trying to please everyone.

I understand that search has been improved a lot in response to
complaints about type-ahead being removed, and this shows that the devs
are trying to meet people's use cases. But ultimately I think it is
misguided and making the search implementation more complex than it
otherwise would need to be. They are really are different features. So I
know there has been a lot of vitriol over this issue, but I would
encourage the nautilus devs to consider that they should become
different features once again. Ctrl-f to search will not confuse
anybody, type-ahead will not confuse anybody, whereas the current search
is trying to be both and so can behave unexpectedly in terms of the
order of search results and whether the search is recursive. Presumably
this means code complexity too.

I also understand that the old type-ahead code was holding back the
codebase and so it was desirable to excise it. I imagine new typeahead
functionality, working as much as possible within the current codebase
and its future directions, would be more amenable to nautilus dev
approval than just restoring the old code. For example, we probably
don't need the popup box in the bottom right as you type. It should just
be type a few characters and have a few-second timeout before forgetting
them, just like it is on other platforms such as windows and macos (I
think). It seems similar to me to the case or removing nautilus handling
the desktop. The code was holding back the codebase, but now we see that
a desktop extension for gnome-shell is in development by the main
nautilus dev.

I do think Nautilus can satisfy everyone's preferences here, and I do
think typeahead will eventually be re implemented once tensions die
down, especially if the nautilus devs can do it on their terms instead
of rejecting a patch that just re-adds code that they don't want to
maintain. A good typeahead implementation would even allow Nautilus to
remove code that customises how the search works to make it more useful
as typeahead - there would no longer be a need for that if typeahead
were present in its own right.

Title:
  file mis-identifies modern executables as application/x-sharedlib

Status in file package in Ubuntu:
  Confirmed

Bug description:
  file doesn't recognize modern PIE (Position Independent Executable)
  x86 executables as such, reporting them as “application/x-sharedlib”.
  Consequently, only non-PIE executables can be opened in graphical file
  managers such as nautilus. This may cause a minor (?) security risk if
  a commonly-published workaround is attempted.

  Expected behaviour:

  $ echo "int main() { return 0; }" > foo.c
  $ gcc -o foo foo.c
  $ file foo
  foo: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically 
linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, 
BuildID[sha1]=6e7749f995a89a53f74ec29d3c16fcf3f56be90f, not stripped
  $ file --mime-type foo
  foo: application/x-executable

  Actual behaviour:

  $ echo "int main() { return 0; }" > foo.c
  $ gcc -o foo foo.c
  $ file foo
  foo: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically 
linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, 
BuildID[sha1]=6e7749f995a89a53f74ec29d3c16fcf3f56be90f, not stripped
  $ file --mime-type foo
  foo: application/x-sharedlib

  Workaround (unsafe?):

  $ echo "int main() { return 0; }" > foo.c
  $ gcc -o foo-nopie foo.c -no-pie
  $ file foo-nopie
  foo-nopie: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), 
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 
3.2.0, BuildID[sha1]=3eb8c581f43c19997e3c828f5a9730dbdc794470, not stripped
  $ file --mime-type foo-nopie
  foo-nopie: application/x-executable

  gcc now defaults to building with PIE enabled for security reasons.

  Also affects: nautilus (and likely other graphical file managers like
  those on Lubuntu) - because nautilus uses mime-type to determine if a
  file is executable, double-click to run a program no longer works.

  Also noted on: Gnome Bugs -
  https://bugzilla.gnome.org/show_bug.cgi?id=737849 (2014) - before PIE
  became the default build option.

  This may be an upstream issue. This may not affect architectures
  outside x86.*

[Touch-packages] [Bug 1721537] Re: No sound from headphone jack on xps13 9350 after ubuntu 17.10 dist-upgrade

2017-10-15 Thread Chris Billington
This problem seems to be the same as in the following two Ubuntu
stackexchange posts:

https://askubuntu.com/questions/768463/laptop-headphone-jack-produces-no-sound
https://askubuntu.com/questions/219342/no-sound-output-from-headphone-jack-ubuntu12-04/859931

A temporary solution mentioned in those threads is:

alsactl restore

which fixes the problem for me.

Might be a problem with Dell hardware specifically - a few comments
mention Dell models. In any case it doesn't seem like a new problem
since the two stackexchange posts are from 2016 and 2012.

[Touch-packages] [Bug 1721537] Re: No sound from headphone jack on xps13 9350 after ubuntu 17.10 dist-upgrade

2017-10-15 Thread Chris Billington
I am also having this problem on a Dell Precision 5520 (which is similar
hardware to both the Dell XPS 15 and Dell XPS 13).

Headphone output worked initially since install and then stopped working
mid-session after unplugging and re-plugging the headphones. I was
adjusting the "Alert volume" setting in sound settings at the time,
which may or may not be relevant. Reebooting, unplugging and replugging,
etc, nothing seems to bring it back.

I am on Ubuntu 17.10 having installed fresh at the time of Beta 2, and
the problem started occurring whilst I was fully updated today.
