[Bug 1863434] Re: 20.04 grub menu not visible

2021-03-13 Thread Giuseppe D'Angelo
I have just upgraded from 18.04 to 20.04.2. 18.04 did not have this
problem and simply showed G

I'm affected by this bug as well. I have a Lenovo W550s; after the BIOS
checks (which just show the Lenovo logo), GRUB does not appear (but the
Lenovo logo is still visible). However, GRUB is there, waiting 10
seconds for my decision.

If don't do anything, after 10 seconds, Ubuntu starts;
I can boot immediately into Ubuntu by pressing enter;
I can boot into Windows by pressing down 2 times and pressing enter.


If I enter the BIOS setup and then quit discarding the settings, then GRUB 
appears as normal.

Might it be that it's simply not configuring/clearing the screen
properly?

Anyways: I'd consider this VERY CLOSE to "makes the system unbootable",
so please do something about it.

[Bug 1909683] [NEW] WARNING: unhandled amd64-linux syscall: 315

2020-12-30 Thread Giuseppe D'Angelo
Public bug reported:

Hi,

Valgrind shipped with focal does not support the sched_getattr and
sched_setattr syscalls, resulting in output like

--1234-- WARNING: unhandled amd64-linux syscall: 315
--1234-- You may be able to write your own handler.
--1234-- Read the file README_MISSING_SYSCALL_OR_IOCTL.
--1234-- Nevertheless we consider this a bug.  Please report
--1234-- it at http://valgrind.org/support/bug_reports.html.

This has been fixed upstream in the meanwhile.

Could it be possible to cherry pick
6323fd5bfd94c3f80e2ff44f16488e0172bd9a96 into valgrind shipped with
focal? Lots of applications make use of those syscalls.

(Sorry, I meant, WHILE upgrading. The upgrade leaves the 18.04 kernel
installed, and also installs the 20.04 kernel. DKMS then tries to build
LTTNG modules for both kernels, failing.)

2020-12-28 Thread Giuseppe D'Angelo
I've just faced this bug, which made the 18.04 to 20.04 upgrade fail. It
seems that, after upgrading, DKMS tries to build LTTNG modules for the
18.04 kernel (4.15), which doesn't work.

A possible workaround is to remove this package before the upgrade, and
reinstall it afterwards.

Could this bug please be reopened, against 16.04? This is not fixed
there.

hplip used to have regular updates in 16.04 as part of SRU, in order to
support new printers that become available on the market, but for some
reason this stopped ~1 year ago. It would be *really* great to get again
regular updates, at least until 18.04.1 / 18.04.2 are out. Is there
anything one can do to help?

[Bug 1743162] [NEW] Nvidia Graphics Debugger does not work with packaged drivers

2018-01-13 Thread Giuseppe D'Angelo
Public bug reported:

Launching any application in the Nvidia Linux Graphics Debugger does not
work with the Ubuntu packaged drivers, but it works by manually
installing the Nvidia upstream drivers (same version). A packaging issue
is the likely issue of this.


Steps to reproduce: 

1) install LGD from https://developer.nvidia.com/linux-graphics-debugger
2) launch it, against x64, connect to localhost, click on the Launch tab and 
click on the "Install debugger" button 
3) try to launch any OpenGL application under 
LD_PRELOAD=~/.tgd/libs/libNvidia_gfx_debugger.so . For instance:


$ LD_PRELOAD=~/.tgd/libs/libNvidia_gfx_debugger.so glxgears
LGD: Starting GTI initialization...
LGD: GLX vendor: NVIDIA Corporation
LGD: Graphics interception initialized
Xlib:  extension "NV-GLX" missing on display ":0".
Error: glXCreateContext failed
Segmentation fault (core dumped)

2017-09-14 Thread Giuseppe D'Angelo
Seems to be working just fine here, thank you very much!

Verification steps:

1. Get a C++11 source file that #includes :

#include 

int main() {
std::string s{"foobar"};
}

2. compile it with clang++ -stdlib=libc++ -std=c++11

3. if it compiles (which now it does) the bug is fixed.

2017-08-30 Thread Giuseppe D'Angelo
Added the SRU info, added ~ubuntu-bug-control.

** Description changed:

  This is mirroring Debian bug #808086 https://bugs.debian.org/cgi-
  bin/bugreport.cgi?bug=808086
  
  Compiling any source file that includes  with clang 3.8 and
  -std=c++11 -stdlib=libc++ results in a compile error.
  
  While this is a minor bug in Debian (as it doesn't ship 3.8 yet), xenial
  does, and that's a major problem as it makes libc++ useless.

+ 
+ Update (30 Aug 2017): as per
+ https://wiki.ubuntu.com/StableReleaseUpdates :
+ 
+ [Impact]
+ 
+ This bug makes it impossible to compile any C++11 source file that
+ includes  with clang 3.8 using libc++. Any non-trivial C++11
+ codebase is affected, making the whole libc++ package useless.
+ 
+ [Test Case]
+ 
+ See above. Create a C++ file that simply contains #include  and
+ compile it with clang++ -std=c++11 -stdlib=libc++ file.cpp.
+ 
+ [Regression Potential]
+ 
+ The current  header simply does not work with clang-3.8 under
+ any condition, so there is no regression potential.
+ 
+ The regression potential for GCC is also extremely limited: no package
+ whatsoever uses GCC in combination with libc++, and the fact that GCC
+ 5.4 -- currently in Xenial -- does not detect the error that Clang
+ detects is just showing that GCC is bugged in this regard.
+ 
+ [Other Info]
+ 
+ The patch/workaround fixes the problem. See also the discussion at the
+ linked Debian bug report as well as https://stackoverflow.com/q/37096062

Hello,

Xenial is still affected by this AFAICS. And yes, I'd like it to be
fixed there.

17.04/17.10 shouldn't be affected, as they're using libc++ 3.9.1 which
has fixed the corresponding bug in Debian. (No idea about ~ubuntu-
sponsors, to be honest...).

Hi Brian,

do you know some way to get a good backtrace for your purpose? Note that
this is 100% reproducible, just run update manager, and even if it tells
you that the system is up to date, switch window focus to somewhere else
to trigger the 8-10% CPU usage.

A quick gdb -p PID and bt doesn't convey much information, the app is
stuck in GTK's event loop:

[Bug 1700672] [NEW] bumblebee / primusrun does not work with NVIDIA 375.66

2017-06-26 Thread Giuseppe D'Angelo
Public bug reported:

In Ubuntu 16.04.2, after upgrading nvidia-375 to
375.66-0ubuntu0.16.04.1, bumblebee stopped working. Attempting to launch
anything with primusrun results in errors.


Upstream bug report seems to be pointing at a flaw in 
/usr/lib/nvidia-375-prime/ld.so.conf , that's why I'm assigning to nvidia-375 
and not bumblebee: https://github.com/Bumblebee-Project/Bumblebee/issues/879

[Bug 1637180] Re: "The computer needs to restart" dialog constantly eats CPU

2017-05-29 Thread Giuseppe D'Angelo
In that case, X usage goes down, and of course compiz isn't there any
more, but the dialog is still eating CPU. I don't know anything about
GTK nor python, so I don't really know how to track this down, otherwise
I would've already done that...

2017-05-24 Thread Giuseppe D'Angelo
Yes. It's likely caused by some broken code calling update() in a loop
or something like that. Yet, we're looking at a 30-40% aggregated
between the app, X and compiz.

[Bug 1687812] Re: Same-application window switcher resizes the application windows

2017-05-02 Thread Giuseppe D'Angelo
Qt-based testcase is attached.

Instructions: 
* Unpack, qmake, make
* Run the application at least twice, making at least one fullscreened
* Trigger the window switcher by clicking on the Unity's sidebar

The fullscreened one will print a wrong resize event. E.g.:

Resized to QResizeEvent(2880, 1572) <- fullscreened
Changed to QEvent(ActivationChange, 0x7ffede2bfa30)
Changed to QEvent(ActivationChange, 0x7ffede2bfa30)
Resized to QResizeEvent(2880, 1516)<- task switcher activated
Resized to QResizeEvent(2880, 1516)<- no idea
Changed to QEvent(ActivationChange, 0x7ffede2bfa30)
Changed to QEvent(ActivationChange, 0x7ffede2bfa30)
Resized to QResizeEvent(2880, 1572)<- exit from task switcher
Resized to QResizeEvent(2880, 1572)

(comments mine)

[Bug 1687812] [NEW] Same-application window switcher resizes the application windows

2017-05-02 Thread Giuseppe D'Angelo
Public bug reported:

The scenario is this:

* Multiple windows of the same application are opened
* Some of them are fullscreen
* The user clicks the application icon in the side tray, starting the window 
switcher for it (so that the user can select a certain window)

This last step actually triggers a *resize* for the fullscreened windows
(for no reason at all): the windows get shrunk vertically a little bit,
and regain their fullscreen size when the user makes a decision.

This might look like a side issue, but it's not: a fullscreen Firefox
(or any other browser) will relayout the current webpage because of that
size change; complex GUI applications like Blender will start their
complicated heuristics to optimize their UI controls; and so on.

For these applications, there's a huge spike in CPU when triggering the
window switcher (CPU used by the applications! Not by Unity or Compiz),
while such switching should be totally transparent to the applications.

[Bug 1637180] [NEW] "The computer needs to restart" dialog constantly eats CPU

2016-10-27 Thread Giuseppe D'Angelo
Public bug reported:

After installing certain updates (kernel, system libraries, etc.), the
"The computer needs to restart" dialog appears periodically, prompting
the user to restart the system.

That dialog eats a constant 8-10% of CPU time. That's the issue. (Yes,
update-manager is niced to 10, but why consuming *any* CPU at all for
showing a static dialog?)

[Bug 1573307] Re: wget crashed with SIGSEGV in __memset_avx2()

2016-09-30 Thread Giuseppe D'Angelo
Guys, this is a serious bug. (In Debian it would be called "important").

Could you please just upgrade to wget 1.18, or at least backport

http://git.savannah.gnu.org/cgit/wget.git/commit/?id=7099f4899880eaefc2c40a3dc7693ab4174a819b

so that wget stops being unusable for ordinary usage?

[Bug 1610168] [NEW] error: 'basic_string<_CharT, _Traits, _Allocator>' is missing exception specification

2016-08-05 Thread Giuseppe D'Angelo
Public bug reported:

This is mirroring Debian bug #808086 https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=808086

Compiling any source file that includes  with clang 3.8 and
-std=c++11 -stdlib=libc++ results in a compile error.

While this is a minor bug in Debian (as it doesn't ship 3.8 yet), xenial
does, and that's a major problem as it makes libc++ useless.

[Bug 1602687] [NEW] Totally broken fullscreen when mirroring a subset of the monitors

2016-07-13 Thread Giuseppe D'Angelo
Public bug reported:

I have two monitors (in the logs: DP-2, DP-4) and one beamer (HDMI-0)
connected to this computer via a GTX 970.

Since this computer is used as a presentation device, I want to
configure the beamer output to mirror one of the two monitors, so that
the presenter can see what's being projected and keep a spare screen for
notes or other stuff.

(As an unrelated note, the @$%#~£ builtin applet in System Settings
*obviously* does not make this setup possible out of the box, but only
let me mirror *all monitors* or arrange them side by side. One needs to
resort to xrandr / nvidia-settings / editing ~/.config/monitors.xml to
make this work; preferably the last one, as it's the only way to make
these settings permanent.)


In the end, this is the setup I want:

When I configure the system this way, windows don't properly enter fullscreen 
any more. 

The launcher bar and the menu bar are still visible, even visually
covering parts of the window. The window just becomes frameless and
somehow maximized.

Cf. the attachment, in which this very Firefox window is not-so-
fullscreen. This is reproducible with any standard Ubuntu app: Firefox,
a terminal, LibreOffice, ...

For extra levels of brokeness:

1) when using Firefox, the launcher and the menu bar do not actually
react to any mouse event. Clicks on top of them get delivered to the
underlying window.

2) any "popup" opened by the fullscreen window actually makes the
launcher and the menu bar disappear. This includes tooltips, contextual
menus, the "burger menu" in Firefox and so on.


Fullscreen works properly only when either *all* the monitors are mirroring 
each other, or they're not overlapping (all side by side or similar), i.e. the 
only configurations that are available from the @$%#~£ builtin applet).

This is still open for Ubuntu 16.04, by the way (confirmed on a GTX
970).

[Bug 1247781] [NEW] Unity 2d panel disappears when (un)docking QDockWigets

2013-11-04 Thread Giuseppe D'Angelo
Public bug reported:

Start any application using QDockWidgets (f.i. the stock mainwindow
demos that come with Qt), and dock/undock dockwidgets. Frequently the
whole panel disappears, forcing a killall unity-2d-panel to get it back.

Release:12.04

[Bug 486474] Re: software-center doesn't alert when trying to delete important packages

2009-11-22 Thread Giuseppe D'Angelo
This is just horrible.

Please raise the severity to critical, since this is a major
malfunction.

And please blame the translation teams or whatever causes this bug to depend on 
the localization.
Why the heck there's no It's used by 5 pieces of installed software in 
Italian?
HOW is it possible to miss a string freeze? And if it's untranslated, why 
doesn't it appear written in English?

Why does Ubuntu ship this kind of pre-alpha software in what should be
the stable distro?

And why there's python in there, and not things like perl? (Just for
having some more interesting fun)

[Bug 248149] [NEW] opengl performance issues and rendering bugs with a GeForce 8600M GT

2008-07-13 Thread Giuseppe D'Angelo
Public bug reported:

With an NVidia GeForce 8600M GT I'm experiencing huge performance issues
with every opengl program.

- Compiz effects are terribly slowly and they move jerkly
- Some opengl app is completely broken, for instance meshlab ( 
http://meshlab.sourceforge.net/ ) or the QtOpenGL module: building and running 
the example here 
http://labs.trolltech.com/blogs/2008/06/27/accelerate-your-widgets-with-opengl/ 
gives the attached result instead of 
http://labs.trolltech.com/blogs/wp-content/uploads/2008/06/openglwidgets2.png .

With a GeForce 6600 everything's fine.

Just did it. I installed the latest nvidia drivers with the envyng-gtk
interface, but the issues are still the same.

[Bug 208137] Re: HP t5000 - vt8623fb - memory size detection failed

2008-06-20 Thread Giuseppe D'Angelo
Hello,
after upgrading a mini-itx machine (VIA CLE266 chipset) from ubuntu 7.10 to 
8.04 the machine began to freezing at boot time. 
Before freezing, for a instant, the screen becomes green, then the display 
shuts down (out of sync error).

I figured out that it was the VIA framebuffer driver vt8623fb that messed the 
whole thing up.
In fact, I added the row
blacklist vt8623fb
to /etc/modprobe.d/blacklist-framebuffer and got the machine working.

Actually, the vt8623fb driver is loaded by both the 7.10's kernel (2.6.22) and 
the 8.04's one, but the latter just crashes;
so please add to the blacklisted framebuffer modules the vt8623fb module, or 
reassign this bug to the kernel package if you think that it is kernel's fault.
