Find all ubuntu packages not from standard repositories

Fri, 24 Feb 2023 09:55:46 +0000

When upgrading from one ubuntu version to the next one, I like to use the opportunity to do some spring cleaning.

To find from which repositories a package was installed we can use:

dpkg -l | grep "ii" | awk '{print $2}' | xargs -n 1 -IX sh -c "apt policy X 2>/dev/null | tr '\n' ' '" | tee all_packages.txt

Then we can inspect the all_packages.txt file and filter for packages which are not from the ubuntu repositories.

Lenovo E540 Standby Problem on Ubuntu 14.04

Fri, 27 Feb 2015 00:03:58 +0000

UPDATE: Lenovo fixed the Bios, after a bios update standby + USB 3.0 enabled work. I used the geteltorito.pl-method descriped in the thinkwiki: http://www.thinkwiki.org/wiki/BIOS_Upgrade

I was furious about a very annoying standby problem my new Lenovo Laptop had. When closing the lid or choosing standby by the menu I did not hear the disks and fans spin down. Instead it kept running. When I then opened the lid, the backlight or something else shined, but the display stayed all black. The only solution was to keep the powerbutton pressed for a hard shutdown. The only solution for now seems to be to:

Boosting Audio Output under Ubuntu Linux

Sat, 26 Oct 2013 12:18:29 +0000

I often had the problem when I wanted to watch a movie or listen to some audiofile and there was background noise I wanted to turn up the volume but it was already at 100% . I thought it should be possible to turn up the signal beyond 100% and decide by myself if the signal is clipping/distored. And there is a very easy solution for the people using pulseaudio.

Fix sluggish mouse in Ubuntu 12.04 LTS

Mon, 26 Nov 2012 12:32:50 +0000

For some time now i have the problem with my Dell Latitude E6510 Laptop that when I plug in a USB mouse the mouse is really slow and sluggish. Usually a reboot fixes this, but this is very inconvenient. Today I tried some googleing again and found at least a workaround to restart the usb-services without rebooting. This usually helps to fix the mouse.

Ubuntu Upgrade to 12.04 LTS -> Libreoffice not working anymore

Tue, 20 Nov 2012 23:49:38 +0000

After a update session of several hours from Ubuntu 11.04 over 11.10 to 12.04 LTS I wanted to start using libreoffice, but it terminated right after start:

$> loimpress
terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'

As root it started without problems, after some googleing and seeing the gdb-trace I found the solution to my problem. Something with the migration of the previous version config files got wrong. So I just deleted them. It is not very elegant, but worked for me and as I did not make any special settings in libreoffice for me it was not painful.

Ubuntu 12.04 Gnome Classic Panel Right-Click does not work

Wed, 15 Aug 2012 13:00:01 +0000

As I was looking for this really a long time I am reposting it:

http://askubuntu.com/questions/66414/how-to-add-panel-applets-to-classic-gnome-panel

With the new gnome and using a classic-session you have to press META + ALT + RightClick to access the panel menu. In my case META is “Alt Gr”. So try this:

Getting DIGITUS-DN-70440 to work with Ubuntu 11.10 and ndiswrapper

Fri, 20 Apr 2012 18:47:52 +0000

I needed a new wlan stick for my fixed pc, as the old one had a very weak reception, so I looked a bit in the shops and found that a realtek stick with reverse-sma port + a extra large antenna just were about 15 Euros. The exact name of the stick is DIGITUS-DN-70440, but it has a Realtek 8192CU chipset on board. Thinking about the fine support for Realtek Ethernet-Cards and reading it had “Linux-Support” I thought it should work like a charm…..Screw this. The crapstick kept kicking me out of the wlan every 10 seconds and I was blaming everthing else until I realised, it’s the driver. The experience I made was: you just can’t use the linux driver…

Gnome Panel Applets not showing up in Applet List in Ubuntu 10.4 Natty

Tue, 17 Jan 2012 13:41:17 +0000

For quite some time I was trying to figure out why my installed applets like “hamster-applet” for example where not showing up in the applet list. Finally I found the solution. You have to install the gnome applet bonobo compatibility package:

Using Citrix Client with Ubuntu 10.10 Maverick 64 bit

Tue, 21 Dec 2010 09:46:08 +0000

Installing the Citrix Client on Ubuntu x86_64_sucked a bit as the citrix client is 32bit.

Get the Citrix-Client here:
http://www.citrix.com/English/SS/downloads/details.asp?downloadID=3323&productID=-1#top

First you have to install the openmotif library also in 32bit

cd /tmp
wget http://de.archive.ubuntu.com/ubuntu/pool/multiverse/o/openmotif/libmotif4_2.3.3-5ubuntu1_i386.deb
dpkg -i --force-all libmotif4_2.3.3-5_i386.deb

then you install the downloaded Package

Gnome multi line taskbar / windowlist

Thu, 25 Nov 2010 09:06:26 +0000

For quite some time I was looking for a solution to have a multi-line gnome taskbar. Under windows you can just drag your taskbar and the windowlist chooser expands to multiple lines. Now I learned: under gnome its almost as easy. Open some Program. Right-click your panel (to which you already added the window-chooser applet) and go to “Properties” there you increase the size until the window-list chooser is multiple lines high (over 50px it was for me). Thats all. Gnome resizes all other icons in the panel to, so I recommend adding a smaller extra panel for them. Or you just live with it (as i do). When you choose, that your virtual-desktop chooser is shown in two lines, then it’s quite okay.
