eudoxos's questions

I would like to retrieve programatically all questions&answers related to one project from launchpad, so that I can import those to a new forum site. I was looking at launchpadlib but I cannot access questions for a single project:

from launchpadlib.launchpad import Launchpad
ll=Launchpad.login_anonymously('')
# get the project; but it does not contain references to questions (it references bugs, translations etc, but not questions
pro=ll.project['woo'] 
# some (random?) question from launchpad, but not for the project I need
ll.questions

using the web API would be also fine. Getting the content in any machine-readable format (JSON, XML) is th goal.

I upgraded to 15.04 and I seem to have issue with permissions talking to D-BUS. Pulseaudio is completely broken (no sound, no volume controls), and systemctl (and also sudo systemctl) reports:

 $ systemctl status   # with sudo or without
 Failed to get D-Bus connection: Operation not permitted

I googled around and saw no clear answer or a way to find out what is happening... Any hint?

EDIT: everything works when booting with upstart.

I recently bought Intel Xeon Phi 7120p and plugged it into a computer running Ubuntu 14.04 LTS. The card shows up in lspci, but then I don't know what to do next.

Should I install updated MPSS modules from here, or do I use (experimental) mic_card and mic_host modules provided with upstream kernel? (The utilities from Intel MPSS are often checking for the mic module, not for the newer ones.)

I am running Jack to driver an external USB card (Focusrie Scarlett 18i8). When I plug the card in, pulse sometimes takes over the card and jack cannot be started (it needs exclusive access to the device).

What is the way to make pulseaudio ignore the 'hw:USB' ALSA device?

There is a host of regressions related to switching keyboard layouts in 13.10. One of them is that the dialogue lets one choose accelerators for selecting previous/next keyboard layout:

Previously, I was able to have accelerator for the first layout (which was Caps Lock) and for the second layout (Shift+Caps Lock) rather than changing the layout with either of those combinations.

Someone knows a workaround for this?

PS: A workaround for the Caps LED indicating the layout is likewise appreciated.

Ubuntu touch preview does not use X11 for graphics. The repository for armhf contains virtually all apps available in desktop Ubuntu, but they cannot be run directly on the tablet (Nexus 10 in my case).

Is there a way to run those using a virtual X-server, perhaps passing through local VNC to be displayed? I have ssh access to the device, so I can run commands normally.

This article at arstechnica suggests Nexus 7 and Nexus 10 will be supported by upcoming Developer's preview of Ubuntu for tablets.

Is that statement backed by some Canonical's source? Is Nexus 10 going really to be supported?

Since the upgrade from Precise to Quantal, the kernel beeps (quite loud) when waking from suspend. Is there a way to disable the beep?

If I select rescue mode in GRUB, ssh is not run. I have to type start ssh to have it running. Can I made this be done automatically for me?

Typical situation is with broken graphics, when I need to login to the box remotely. Now, I have to type start ssh blindly first and hope.

In quantal, python3 is supposed to be the default version of python. However, it seems that e.g. python-matplotlib package is only packaged for python 2.7 (and there is no python3-matplotlib). What is the transition plan? When is python3 going to be fully supported, including major packaged 3rd party modules?

I have gnome-panel with various extensions installed. The right half is crammed so that many items are not displayed (I already removed volume, username, a11y, ...). Is there a way to make the items stretch to the left, to the unused space?

EDIT: I am using gnome-shell 3.4 from precise repos.

I've installed a number of packages from PPAs, and I would like to revert to official versions now. Many of the PPAs no longer exist in /etc/apt/sources.list.d, so ppa-purge will not work on them.

What is the most straight-forward way for that?

I have a one-file boost::python module which is compiled using a one-line Makefile. What is the recommended way of packaging it? Distutils? Makefile? CMake? Use CDBS then? Are there some documents on the subject?

I have two GPUs, one is AMD (fglrx-updates) and one nVidia (nvidia-current), drivers from x-swat PPA. The AMD card is used byt xorg (without problems). Both devices show up in lspci|grep VGA:

01:00.0 VGA compatible controller: ATI Technologies Inc Device 6718
02:00.0 VGA compatible controller: nVidia Corporation Device 1200 (rev a1)

The nvidia kernel module is loaded (dmesg|grep nvidia):

[   16.033488] nvidia 0000:02:00.0: enabling device (0000 -> 0003)
[   16.033501] nvidia 0000:02:00.0: PCI INT A -> GSI 40 (level, low) -> IRQ 40
[   16.033507] nvidia 0000:02:00.0: setting latency timer to 64

OpenCL problem

I created /etc/OpenCL/vendors/nvidia.icd containing

/usr/lib/nvidia-current/libcuda.so

The device is detected, platform NVIDIA CUDA, device GeForce GTX 560 Ti. However, no code gets compiled for the device, clBuildProgram always returns CL_BUILD_RPOGRAM_FAILURE and querying clGetProgramBuildInfo crashes with uninformative backtrace

#0  0x00007ffff7442bef in ?? () from /lib/x86_64-linux-gnu/libc.so.6
#1  0x00007ffff22c0e67 in ?? () from /usr/lib/nvidia-current/libcuda.so

The program is build with cl.h from Intel's SDK; that is OK since everything was fine until I installed the AMD card alongside.

Running /usr/share/doc/python-pyopencl/examples/benchmark.py crashes just the same (in pyopencl::program::get_build_info).

Any hint on what is wrong?

In gnome-shell, menus on the top panel are flat -- submenu is not displayed on the side, as it used to be, but is opened in the upper level:

Is there a way to change the behavior back? Is it hard-coded, gtk3 theme, gnome-shell theme or something else?

I connect to mobile internet over bluetooth and the Nokia C7 phone. The bluetooth connection works successfully when the phone is freshly started (i.e. I click on the connection, properly set-up, in the nm-applet and it connects), but when not, I get this in dmesg:

When the phone is restarted, the connection works. I had the same problem with other provider (Orange in Austria), and had no problems with other phone with the same (Vodafone) provider.

I have found no C7 posts mentioning such problems, so I assume it works fine under windows. Any hints?

(I am running up-to-date Ubuntu 11.10)

I have a patch against vim which applies to packaged version. I would like to automate this, so that when new ubuntu is released, the newer unpatched vim gets patched & built using a recipe. I read documentation on recipes, though I am not sure how to apply a patch.

Should I create branch with modified source and have the recipe merge it? How does that handle when patched branch gets out-of-date with the distro package in newer release? (The patch will very likely still apply; but will the branches be able to merge as well?)
