Where is the power off in Gnome 3?

January 31, 2012 1 comment

I recently installed Gnome 3 and I must say that in my old machine, it runs significantly better than Unity. Indeed, I wasn’t able to run Unity smoothly.

But there are things in Gnome 3 (and in Unity) that I’ve not accustomed.

For instance, there is no power off button in Gnome 3 user’s menu…

That’s false. Simply it’s hidden. You can show this option hitting the Alt key while showing the user menu.

There are some more tweaks, it’s better to run this cheatsheet and you’ll feel more comfortable with Gnome 3:

Filezilla 3.5 crashes when drag&drop a file (Ubuntu 11.10 64 bits)

January 18, 2012 Leave a comment

When I try to drag & drop a file from left pane to right pane, filezilla crashes due to a segmentation faul. This is the dmesg output:


[73197.174428] filezilla[18057]: segfault at 41 ip 00004f26ec47d100 sp 00008fffff165f50 error 4 in libwx_gtk2u_core-2.8.so.0.7.0[8f26ec2a5000+386000]

I searched around for this bug (already reported to filezilla) and the fix is to install the newer version of wxWidgets (2.8.12, the latest stable release). This is how to solve in Ubuntu 11.04:

http://wiki.wxpython.org/InstallingOnUbuntuOrDebian

But this fix doesn’t work for ubuntu 11.10 64 bits (with Gnome 3). I’m still getting the segmentation fault.

So, I decided to build the latest version of wxWidgets (2.9.3.1):


$ sudo python2.7 build-wxpython.py --build_dir=../bld --install

[...]

configure: error: OpenGL libraries not available
Error running configure
ERROR: failed building wxWidgets
Traceback (most recent call last):

 File "/home/miquelete/wxWidgets/wxPython-src-2.9.3.1/build/tools/build-wxwidgets.py", line 62, in exitIfError
 raise builder.BuildError, msg
BuildError

Install the open source openGL Utility Toolkit:


sudo apt-get install freeglut3 freeglut3-dev

And now I get another error:


checking for GST... configure: WARNING: GStreamer 0.10 not available, falling back to 0.8
checking for GST... configure: WARNING: GStreamer 0.8/0.10 not available.
configure: error: GStreamer not available

I need GStreamer package. I’ve tried a bunch of packages to get it work, sure that some of them are not requiered, but this worked for me:

$ sudo apt-get install ubuntu-restricted-extras
$ sudo apt-get install gstreamer0.10-ffmpeg gstreamer0.10-fluendo-mp3 gstreamer0.10-gnonlin gstreamer0.10-sdl gstreamer0.10-schroedinger gstreamer0.10-plugins-ugly totem-plugins-extra
$ sudo apt-get install libgstreamer-plugins-base0.10-0 libgstreamer0.10-0 libxml2
$ sudo getlibs -p gstreamer0.10-pitfdll
$ sudo apt-get install libgstreamer0.10-0 libgstreamer0.10-dev gstreamer0.10-tools gstreamer0.10-plugins-base libgstreamer-plugins-base0.10-dev gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly gstreamer0.10-plugins-bad gstreamer0.10-ffmpeg

Now I can build, but during the make install I get this one:

src/helpers.cpp:15:20: fatal error: Python.h: No such file or directory

compilation terminated.
error: command 'gcc' failed with exit status 1
ERROR: failed building wxPython.

This is because I don’t have Python.h in /usr/include/python2.7/. To get it, install this package:

$ sudo apt-get install python-dev

Once added this package, the installation
Change to ../bld folder and check the version of wxWidgets:


$ wx-config --version
2.9.3

And now I can get it work!

Install Lotus Notes 8.5.3 on Ubuntu 11.10 64 bits (with gnome3)

January 12, 2012 12 comments

I use Lotus Notes at work (not for pleasure), and I’ve already installed Lotus Notes 8.5.1 on Ubuntu 11.04 64 bits.

But due to a crash in my Ubuntu, I have had to reinstall Ubuntu 11.10 64 bits on top of the 11.04 installation. I reuse my partitions to install Ubuntu (home, etc.), and then I’ve followed this post to install the new Lotus Notes 8.5.3.

http://usablesoftware.wordpress.com/2011/10/10/install-lotus-notes-8-5-3-en-on-ubuntu-11-04-64bit/

Don’t forget to install the libs at the bottom of the post before installing lotus notes.

In my case, as I reuse the old partitions, when I first install lotus notes, I get an error:


cat: /opt/ibm/lotus/notes/framework/rcp/systemdata/logs/rcplauncher.log: File or folder does not exists

cat: /tmp/rcplauncher.log: File or folder does not exists

So, i moved bak the old folders of the prior installation (8.5.1), the lotus folder at home, and the /opt/ibm folder:


mv ~/lotus ~/lotus.bak

sudo mv /opt/ibm /opt/ibm.bak

And now the installation works fine.
After install, I move back my notes.ini, user.id, bookparks.nsf and names.nsf from my old installation to ~/lotus/notes/data/.

Then, I’m still getting some issues with blank screens, so, like in prior installations of notes in ubuntu with the same problem, I’ve copied these libraries to /opt/ibm/lotus/notes:

wget http://www.benkevan.com/upload/lotus_notes/libgdk-x11-2.0.so.0
wget http://www.benkevan.com/upload/lotus_notes/libgdk_pixbuf-2.0.so.0
wget http://www.benkevan.com/upload/lotus_notes/libgdk_pixbuf_xlib-2.0.so.0
wget http://www.benkevan.com/upload/lotus_notes/libgtk-x11-2.0.so.0
sudo mv *. so.0 /opt/ibm/lotus/notes
And now I can enjoy Lotus Notes apps!
