en-us rdesktop keymap problem with thinstation 2.3beta

February 28, 2008 Leave a comment

The beta version of thinstation has a permissions problem on some keymap files that does bad things to rdesktop sessions, at least with en-us. The arrow keys stopped working along with the page up, page down, home, end, etc. The number pad keys worked in navigation mode only.

Here is a simple fix, if you have a local build folder.

As root:

cd <path to thinstation folder>

find packages/keymaps-* -perm 0600 -print|sort|xargs chmod 644

./build

disabling tap to click in gnome

February 25, 2008 Leave a comment

I can barely function on a laptop with tap to click enabled. The newer versions of Ubuntu simply have a GUI tab in the mouse preferences. In RHEL, CentOS, and many other distribution which use gnome, there is no GUI interface. Here is how to you disable it:

sudo nano /etc/X11/xorg.conf

Find the “InputDevice” section (which has the Identifier “Synaptics” line):

add the following line:
Option “MaxTapTime” “0”

Save and exit from the file (ctrl-x, y). The next time you restart X the tapping will be disabled.

No audio on Dell laptops with ubuntu gutsy 7.10

February 23, 2008 Leave a comment

I had this exact same problem with a Dell Latitude D531 and a Dell Precision M4300. With a fresh install they both reported not having audio drivers, but they could see the audio card in lspci.

sudo apt-get install linux-backports-modules-generic

reboot

Sound is working!

fast network file copying using tar and nfs

February 16, 2008 Leave a comment

Configure an NFS export on the remote machine (e.g. 192.168.1.3) to copy to (e.g. /remotedir).

Create empty directory on local machine, and mount remote directory to it:

mkdir /remotedir

mount 192.168.1.3:/remotedir /remotedir

tar -c localdir/ | tar -C /remotedir/ -xv

That will copy contents of localdir to /remotedir on remote machine.

I used the above method to quickly copy some vmware images to a new server. scp copies were taking way too long. I was using ubuntu dapper servers, but it will work basically the same on any linux machines.
