Forwarding sound on LAN

Here’s how to simply forward sound from one computer to another in Ubuntu. First, install paprefs: 1sudo apt-get install paprefs Start it by executing paprefs in a terminal.

I’ll collect the Ubuntu utilities I find useful in this (continuously updated) post. fslint: finds duplicate files in folders Lookit: captures screenshot and uploads it to FTP/SSH/various image sharing sites.

I got a black screen under Ubuntu when the screensaver got activated, or I switched to console mode with ctrl+alt+1 and back to X with ctrl+alt+7. The cause of the problem is gnome-screensaver, so I uninstalled it, and installed xscreensaver instead. I created a symlink at /usr/bin/gnome-screensaver-command which points at /usr/bin/xscreensaver-command. This is needed because […]

Samsung Galaxy S lagfix

I’ve found out that the problem is with the RFS file system on the phone. First I updated my phone to Android 2.2 using Kies. This installed the JPH 2.2 firmware. Then I rooted my […]
