[HOW TO] Remap Xbox 360 controller buttons in Xubuntu

On a previous article I wrote about using the Xbox 360 controller as a mouse. The --mouse option is actually a shortcut for a custom button configuration. You can map any button on the controller to any key/combination. In this article I'll layout the basics. Further information can be obtained in the references. There are two ways of providing a custom mapping: Command line options: use ui-buttonmap to map a button and use ui-axismap to map a axis. The syntax consists of assigning a button name to a symbol. Example: ui-buttonmap x=XK_Tab,a=XK_Control_L+XK_a ui-axismap y2=XK_plus:XK_minus . This will map "X" as "Tab", "A" as "Super+a" and the right stick up is "+" and right stick down is "-". Configuration file: use config to provide the path for a configuration file. The config file has a ini format. Use the sections ui-buttonmap and ui-axismap for configuring the mappings. You can

[HOW TO] Install Guake (Quake-like terminal) in Xubuntu

Some time ago I wrote about installing Tilda in Xubuntu . Now I gave Guake a try (another terminal that slides in from the top of the screen). Guake running on Xubuntu There are some reasons for liking Guake better: The width is set to 100% (Tilda has some problems when changing monitors). The height can be adjusted with the mouse. All key bindings can be customized. The tab bar is quite useful and it's easy to rename tabs. Tilda is still a good program, though, so if you're undecided give them both a try and see which suits you best. Install Open a terminal window and run: sudo apt-get install guake -y Usage Guake can be accessed via Applications Menu > Accessories > Guake Terminal or typing the following command: guake . Guake's preferences editor can be directly accessed using the command: guake-prefs or you can right-click on Guake and select Preferences .

[SOLVED] Suspend causes reboot on Sony Vaio

I was using a Sony Vaio SR29VN and when I tried to resume from suspension, the laptop would reboot instead of resuming. I understand that this may affect other models, however, I don't have a list. Luckily it's easy to fix: we need to add acpi_sleep=nonvs kernel option to the grub settings. Fix Edit (with root permissions) the line GRUB_CMDLINE_LINUX on the file /etc/default/grub , adding the option acpi_sleep=nonvs . Then run this on the command line: sudo update-grub2 References suspend causes reboot

[HOW TO] Remove old kernels in Ubuntu

After running the system for a while the Linux kernel gets updated and the old versions are kept installed, even though that aren't needed any more. In this article I provide a way to remove automatically any kernel version that is older than the current being used. By the way, I was able to recover more than 1GB of free disk space by running this.

[SOLVED] xfrun4/xfce4-appfinder launches very slowly

xfrun4 is a little Xfce program that allows to run commands, without having to open a terminal window. Since Xfce 4.10 it also works as a application launcher. It is summoned using Alt+F2 , and usually it pops right up, but lately it takes several seconds, sometimes almost a minute, to open. When trying to run it from the terminal, it prints this error: (xfrun4:6232): xfce4-appfinder-CRITICAL **: Failed to open window: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. This bug has been reported and there's a workaround: use the --disable-server option. Fix So to fix this we'll replace the command for the Alt+F2 shortcut with " xfrun4 --disable-server ". Open a terminal window and run: xfconf-query -c xfce4-keyboard-shortcuts -p '/commands/custom/<Alt>F2' -s
