[Bug 1283938] Re: Ubuntu 14.04 blank screen after wakeup from sleep

2014-04-24 Thread Fernando Perez
Confirming this on a desktop machine, Intel(R) Core(TM) i5-2500K with
built-in Intel graphics and no additional video card at all.

Suspend/resume was working just fine on 13.10. After upgrade to 14.04
suspend still works, but upon resume the screen is blank. The only way
to get it back is to go to a text console and force-kill X so it
respawns.

I'm running KDE as my desktop, in case it matters.

[Bug 1033669] Re: compizconfig causes python to segfault in quantal

2012-11-16 Thread Fernando Perez
Same as dseidel here:

In [1]: import compizconfig

In [2]: ctx = compizconfig.Context()
compizconfig - Info: Backend : ini
compizconfig - Info: Integration : true
compizconfig - Info: Profile : default
Segmentation fault (core dumped)

Immediate segfault upon creating the context, before any invalid
settings have been passed.  This is using XFCE4 on ubuntu 12.10, freshly
upgraded from 12.04.

Basically this means that now it's impossible to tweak any Compiz
settings on 12.10.

[Bug 871176] Re: KnownFailure should not be registered as a global nose plugin

2011-12-02 Thread Fernando Perez
Many thanks, @jtaylor!

Any chance the fix could be backported to 11.10?  It's a trivial fix and
means that right now, nobody can safely run the ipython test suite on
11.10... And it may also affect other packages that also try to use
numpy's KnownFailure plugin.  Given how tricky to debug the problem is
if you get hit by it (in the ipython case, two expert developers
independently wasted several hours each trying to sort it out), it would
be great to see it fixed in the current ubuntu.

[Bug 871176] [NEW] KnownFailure should not be registered as a global nose plugin

2011-10-09 Thread Fernando Perez
Public bug reported:

Currently there's this in the ubuntu oneiric package:

amirbar[matplotlib-1.0.1.egg-info] pwd
/usr/share/pyshared/matplotlib-1.0.1.egg-info
amirbar[matplotlib-1.0.1.egg-info] cat entry_points.txt 
[nose.plugins]
KnownFailure = matplotlib.testing.noseclasses:KnownFailure

this causes no end of trouble, such as the IPython test suite failing.

Please don't register this as a global nose plugin, it's really meant
only for matplotlib use.  In fact it was copied from numpy.  We'll work
in mpl to hide it further and only expose our copy if we can't find the
numpy one, but the ubuntu package should NOT expose this as a global
nose plugin AT ALL.

[Bug 868000] Re: Fix for #821290 broke M-f/M-b behaviour in gnome-terminal without menubar

2011-10-06 Thread Fernando Perez
I suspect (but could be wrong) this is related to the fact that in
11.10, now gtk won't honor the Emacs keybindings theme.  Now even if the
gtk key theme is set to Emacs, Ctrl A/E/K etc don't work anymore as
they used to in any GTK text field (gedit, firefox text areas, etc).  I
tried to report it as a separate bug but keep getting launchpad server
errors that discard my report, so I gave up and found the most similar
existing bug.

2010-04-22 Thread Fernando Perez
This is really an annoying bug, but I'm a bit lost on how to approach
it.  For example, we could hardcode a check on 'print' being on the line
to avoid triggering the autocall behavior, but that would break
legitimate use of autocall for users of print as a function...

Any suggestions welcome.

[Bug 270856] Re: IPython hangs with PyGTK

2010-01-09 Thread Fernando Perez
Michiel, the problem is that in this case (I just tried) the shell
blocks while plot windows are open...

For 0.10.1, it would be nice to either have a solid solution here or to
remove that warning, because it's not very informative to the users.  I
tried changing the code to have a single-threaded shell simply calling
set_interactive(True/False), but neither worked: the shell just blocks
on input.

Ultimately in 0.11 we have a much more robust solution to this using
PyOS_InputHook, and so far it's looking very solid.  So if someone
proposes for 0.10.1 a patch that takes proper advantage of the
set_interactive call, I'll be happy to apply it, otherwise there's no
point in giving that warning (since using the non-threaded shell and gtk
just blocks, as best I can see in testing here on Ubuntu Karmic with a
current pygtk that has set_interactive).

[Bug 414967] Re: print statements get incorrectly mangled by the autocall feature under Python 2.6

2010-01-09 Thread Fernando Perez
Mmh:

- Beni, I've applied your patch to 0.10.1 and trunk-dev, thanks.

- As for the real problem with print, I'm not sure what to do: I've
spent some quality time with the Python sources, trying to write some
ctypes-based utilities to fish into the compiler state struct (see
compiler.c and future.c in the Python tree), but no success yet.  It's
not the type of code I'm familiar with so it's likely to be slow/hard
going, and I don't have the time for more on this now.  Ultimately I'm
leaning towards suggesting that people simply put in their config file

from __future__ import print_function

and be done with it!  That way they start getting used to print as a
function everywhere, in preparation for 3.0, they can learn the syntax
of the function, and IPython will happily put the parens in there for
them.

It seems like a better way to address this than to sink days of work
into an obscure tool to spelunk into the compiler internals at runtime
to fish a __future__ flag out...

Thoughts?

If people agree on this, closing the bug will just require adding the
text above to the docs/faq.

[Bug 178509] Re: [hardy] wifi (iwl4965) is slow to return after suspend/resume

2009-02-22 Thread Fernando Perez
I think this bug should be reopened, since the problem persists.  I'm
running Intrepid on a Dell 1330 with the Intel 3495 card:

0c:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG
[Golan] Network Connection (rev 02)

and I get the same 30 second delay before the wireless connection starts
up again after suspending.  Here's some perhaps useful info from
dmesg...

After resuming:

[167761.512525] Enabling non-boot CPUs ...
[167761.512525] SMP alternatives: switching to SMP code
[167761.519438] Booting processor 1/1 ip 6000
[167761.507072] Initializing CPU#1
...
About 6 seconds later, the wifi card comes up (and the LED confirms this):
[167767.261785] iwl3945 :0c:00.0: enabling device ( - 0002)
[167767.261797] iwl3945 :0c:00.0: PCI INT A - GSI 17 (level, low) - IRQ 17

[167767.346115] Registered led device: iwl-phy0:RX
[167767.347004] Registered led device: iwl-phy0:TX

Here, it seems to try to immediately authenticate with some AP:
[167767.347661] eth1: authenticate with AP 00:11:0a:e9:a4:e1
[167767.365973] ADDRCONF(NETDEV_UP): eth1: link is not ready
[167767.385833] eth1: authenticate with AP 00:11:0a:e9:a4:e1
[167767.584035] eth1: authenticate with AP 00:11:0a:e9:a4:e1
[167767.784085] eth1: authenticate with AP 00:11:0a:e9:a4:e1
[167767.984028] eth1: authentication with AP 00:11:0a:e9:a4:e1 timed out

But that didn't work, and next it tries another one, about 30 seconds later:
[167795.730581] eth1: authenticate with AP 00:1e:c7:4f:2f:f1
[167795.732466] eth1: authenticated
[167795.732481] eth1: associate with AP 00:1e:c7:4f:2f:f1
[167795.735924] eth1: RX AssocResp from 00:1e:c7:4f:2f:f1 (capab=0x431 status=0 
aid=4)
[167795.735937] eth1: associated
[167795.737327] ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready
[167805.893058] eth1: no IPv6 routers present

And that worked.

Now, I have no idea what the first AP might be, but it's NOT the network
I was just on (I did this test by suspending and resuming my laptop at
home, without moving or changing networks).

I noticed that my EEE PC on which I just yesterday put 8.10,  and which
ONLY knows about this AP, reconnects instantly on resume.  So I'm
wondering if the problem is that NetworkManager is by default attempting
to connect to some other AP first, instead of to my main one...

I'll be happy to provide more details if needed, I'd really like to see
this fixed.
