Randomly and fortunately not too often (maybe two or three times in the last 5 months) the mouse cursor freezes on my laptop (Ubuntu 11.10 64Bits). This usually happens when using thunderbird, however I don't have a test-case to report to launchpad yet. This is quite annoying and what I did in the previous occasions was to hit CTRL-ALT-F1 and restart lightdm. However It has just happened once

This is just quick and dirty post. A oneliner to check if all your server services have started rightly after a reboot. This first attempt is aimed for Debian and derivatives: checkservices () { for service in /etc/rc2.d/S*; do STATUS=$(/etc/init.d/$(ls -l $service | awk '{print $NF}') status 2>/dev/null); [ "$STATUS" != "" ] && printf "Status of ${service##*/}:\t$STATUS\n"; done; } Example:

Custumization of Unity in Ubuntu 11.10; about:config doesn't work spanish version - all english posts Unity probably due to a misguided Ubuntu's "zero-config" policy cannot be customized by the end user.

spanish version - all english posts How to disable the guest account in Ubuntu 11.10? Ubuntu 11.10 uses lightDM as the default display manager. Certainly it looks cooler than the old GDM, but by default it comes (in the ubuntu package) with a guest session enabled which is at least an arguable decision from many points of view (utility, security, etc). To disable that guest login account

spanish version - all english posts I've just realized that the reiserfs partitions of an old PC are not associated with their corresponding UUID in /etc/fstab. I usually use UUIDs in fstab to avoid problems when adding/removing disks. This particular PC has several partitions with reiserfs filesystem. Many years ago I preferentially used reiserfs instead of ext2 for obvious reasons. With the
