Android x86 Multiboot with Win7 and Ubuntu on Acer1825

April 17, 2011

Most of you know that nice Androidx86 release from arobase for the Acer1825, but a lot of you asked for installation on hard-disk. I have done it and here comes, how it works:

First my start configuration: I had a installation of Windows7 (seldom used) (NTFS) and Ubuntu 10.10 on LVM(ext4), no free space for a new partition. read more

Automatic placing of onscreen keyboard in linux

March 10, 2011

This guide is writte for my Acer 1825 but it should work on all linux devices which need a onscreen keyboard like onboard.

I got the idea of building this script from Tom/drnessie from the ubuntuforums.org (http://ubuntuforums.org/showthread.php?t=1486671&page=17), because he tried to make a improvement of my onscreen keyboard show/hide script from this post. read more

Using ginn for adding multitouch gestures to ubuntu (for Acer 1825)

February 20, 2011

In my last post I explained were you found a tutorial for installing a real multitouch driver for the ACER 1825 and said I don’t know how to use these multitouch support. Thanks to Tom/drnessie who recommended ginn to me.

Ginn is a daemon which recognizes multitouch gestures with the ubuntu utouch interface and translates them to global or application specific shortcuts. read more

Improvements on gyro auto rotation for ACER 1825

February 18, 2011

In two old posts I described, how you could use the gyro sensor of the Acer 1825 for auto rotating your screen and how you could enable and disable this feature with a special button.

Switch active window via shortcut between two monitors on linux

January 25, 2011

SCRIPT UPDATED: ERROR CORRECTION AND IMPROVEMENTS DEPENDING SOME SPECIAL CONDITIONS 30.1.2011

If I use two monitors in windows environment I use some scrips of the tool active aid http://activaid.telgkamp.de/ to have the ability to switch the active window between both monitors with a shortcut. Since I meanly use Linux on my private pc and laptop I missed this feature badly and I did not find some tool or script which fills this gap. But like the world works as Linux user, if something does not exist, make it on your own: My result is a bash-script which switches the active window between both monitors. This script based on wmiface, a tool which gives you the ability to control windows from a NetWm compatible Window-Manager, so at least KDE and GNOME (I tested it on GNOME). A special requirement for my environment is the ability to switch between to monitors with different resolutions. To use my script you need to install wmiface on your distribution, I think you will not find it in your package manager, but you could download install packages for nearly all huge distributions (or the source) from this site: http://kde-apps.org/content/show.php/WMIface?content=40425 If you use debian (like my on my workstation) choose the ubuntu packages. On my test-system(debian 64 testing) the ubuntu 64 packages works fine. Here is the script, download it or copy it and save it to a file. Give execution rights wiht chmod +x. (I copied it to /usr/bin but this it not necessary. You could run it from every directory.) You should test the script in terminal and if everything works fine you could assign this script to a shortcut with gnome-keybinding-properties. Do not forget to edit the resolution for the left and right monitor in line 10 and 11. If you have more than two monitors you should be able to write your own script based on my work.

Some hint for google chrome/chromium users, the script does only work if you set the setting in chrome for using the system frame and not the special one from chrome. read more

My first kernel module:Acer 1825 gyro sensor joystick

December 20, 2010

From this thread on ubuntuforums.org I got a link http://pof.eslack.org/blog/2008/06/05/gsensor-joy-htc-shift-g-sensor-joystick-linux-kernel-module/ of a blog where the author presents his kernel module for using the gyro sensor from the HTC Shift (which is similar to the gyro sensor from the Acer 1825) as a joystick. This site is although the base for my presented scripts and applications for auto rotating the display of the Acer 1825. The problem is, that the presented module does not work on a current kernel, because the architecture of the i2c-bus driver changed in linux kernel 2.6. read more
