I am using Ubuntu 10.04 Lucid Lynx in my PC. The Ubuntu Design Team has decided to move the Minimize, Maximize and Close buttons to the left of the title bar. Not exactly like Mac OS X, which looks like the following:
while Ubuntu button layout is as follows:
The difference is the order in which they appear.
UPDATE April 2: The button order in Lucid will now follow Mac OS X style.
I was wondering if we could downgrade from Ubuntu 10.04 Lucid Lynx Alpha to Ubuntu 9.10 Karmic Koala. So I decided to put it upon test and I succeed. So, I am sharing this with those who wish to keep using stable Karmic Koala till the final version of Lucid is out.
Please note however, that all the installed applications will be lost, however the settings and files in your home directory will be preserved. So, for example if you have a huge list of saved sites on your Filezilla client, Filezilla will be gone, but when you install Filezilla on your Karmic, the settings should work. Also, your Firefox browsing history, preferences and other settings will also be preserved.
and upgraded and installed nautilus, murrine-themes , gtk2-module-rgba and gtk2-engines-murrine to enable rgba transparency in my Ubuntu 10.04 Lucid Lynx Alpha. That looks really cool. It was supposed to be coming with Lucid, but was dropped due to bugs. The programs started crashing for me too. I was done with adding exceptions to /etc/profile.d/gtkrgba.sh because almost every new program crashed. So I decided to remove the rgba module altogether. Just removing the repository does not help. So, here are the removal instructions. Find and removing the PPA Packages and installing original versions: Open up synaptic. Make sure you have not disabled the rgba repository. Click on “Origin” in the lower left of Synaptic and in the upper left pane, select LP-PPA-erik-b-andersen-rgba-gtk/lucid. Now, the packages installed via the repository can be seen in the main window of synaptic. Select gtk2-engines-murrine and click on Package>Force Version and choose non-ppa version. Repeat the same for libnautilus-extension1, murrine-themes and nautilus. Mark gtk2-module-rgba for removal. Apply the changes. Now, you can safely remove the PPA repository. Remove the rgba module listing from profiles: Even after the removal of ppa versions, you will still get a message
When I used Windows, I had come across several “system cleaners and optimizers”. One I liked was CCleaner (Crap Cleaner). It had a nice interface and was capable of cleaning cache and data of several applications.
I found a similar application for my Ubuntu 10.04 Lucid Lynx Alpha. It has similar interface and features. It is called bleachbit and can be installed via Synaptic (universe repos need to be enabled) and can be accessed from Applications>System Tools>Bleachbit. It is also capable of wiping the data so that it is impossible(or lets say difficult) to recover. It can also clean backup files (those hidden with ~ at the end of the filename, .bak, .tmp and more) with Deep Scan.
I am using globalmenu 0.7.9 (Mac OS X like Global menu for Gnome) from the globalmenu-team PPA (Karmic as Lucid is not available now) in my Ubuntu 10.04 Lucid Lynx. I get the following error on terminal when I try to launch any gtk applications from the terminal:
Gtk-Message: Failed to load module "gnomenu-panel": libgnomenu-panel.so: cannot open shared object file: No such file or directory
Gtk-Message: Failed to load module "globalmenu-gnome": libglobalmenu-gnome.so: cannot open shared object file: No such file or directory
However, the gnomemenu-panel works fine, I wanted these messages to not appear. I opened up /usr/lib/gtk-2.0/modules and found that the plugin had different files than listed in the error message. To fix the problem, I just created symbolic links to the existing files. This is how I did it from the terminal:
I am using balazan theme in Ubuntu 10.04 Lucid Lynx Alpha 4 from breathe ppa for Karmic Koala since Lucid PPA was not available when I started using Lucid. I saw this message when I launched gedit from terminal (gnome-terminal):
/usr/share/themes/balanzan/gtk-2.0/gtkrc:89: Murrine configuration option "scrollbar_color" is no longer supported and will be ignored.
/usr/share/themes/balanzan/gtk-2.0/gtkrc:93: Murrine configuration option "gradients" is no longer supported and will be ignored.
Seems like the theme I’m using has some depreciated configuration options after Murrine update. I opened the /usr/share/themes/balanzan/gtk-2.0/gtkrc file (as root) using the following command from Alt+F2
I am using Ubuntu 10.04 Lucid Lynx Alpha 2 and when I updated today, when I held down a key, I did not get repeated keypresses as I would normally. I don’t know which update actually caused this, but it was due to some packages I upgraded recently (any ideas?). I just went to Keyboard Preferences (System > Preferences > Keyboard) and checked “Key presses repeat when key is held down” but it still did not work, for some reason. Then, I just played around with the sliders (Delay and Speed) and it started working. Finally, I typed in the Test Field and set the preferences to my taste. I have written this just in case somebody does not figure this out themselves. Hope this is helpful.
I am using Ubuntu 10.04 Lucid Lynx Alpha and I encountered this while installing ltsp-server. The package being configured was ldm-server.
I was installing an application and Synaptic Package Manager just froze forever while configuring a package. I had to shut it down using sudo killall synaptic. Then, when I tried to launch t again, it would come up with “Unable to get Exclusive Lock” message. When I tried apt-get from Terminal, I got /var/lib/dpkg/lock – open (11 Resource temporarily unavailable).
OpenShot is one of the best non-linear video editors coming up for Linux. You can install development version of OpenShot by adding ppa:openshot.developers/ppa to Synaptic>Settings>Repositories>Other Software>Add. Then, it can simply be installed from Synaptic Package Manager.
