SLED 12 ships with GNOME 3.10 which means GDM 3. GDM 3 provides very little scope for customising how it looks. In this article I’ll describe some pros and cons of the officially provided ways of customising GDM 3 and how you can go further customising by hacking. Testing changes will require you to repeatedly …

Additional multimedia codec support for SLED 12

As with most Linux distributions, SLED’s out of the box multimedia capability is somewhat limited in terms of codec support. It has support for MP3, the OGG family and some others, but it doesn’t have support for commonly used codecs such as H264 and AAC and those required for DVD playback. There are packages available …

As has been much publicised recently, (including Understanding POODLE), an unfixable vulnerability has been found in SSLv3 and it is recommended that support for it be disabled. Mozilla have said that SSLv3 will be disabled by default in Firefox 34, but SLED, very sensibly for an Enterprise distro, uses the Extended Support Releases of Firefox …

Setting and locking preferences in Firefox is something that Mozilla provides documentation for but unfortunately the methods described don’t work for Firefox as it is packaged by SUSE for SLED. Here’s my guide to how I handle the setting of default preferences and the locking of Firefox preferences in SLED.

About a year ago I wrote up a Cool Solution for moving Firefox’s urlclassifer3.sqlite file out of a user’s home directory. This Cool Solution describes a better method of doing this which also redirects the Cache and other parts of the profile that don’t need to be persistent.

Firefox’s urlclassifier3.sqlite can grow quite large which can be problematic where users have quotas applied to their home directories. Unfortunately Firefox provides no method to relocate the file, but it is possible to relocate on Linux using a wrapper script.

Something I’ve found very useful when managing machines running SLED is building my own rpms. If I want to put scripts on to the machines I package them as an rpm and then if I need to update them, I can put the new versions in to the rpm, increase the version number and push that out as an update. This is something I do quite a lot but it took me quite a bit of reading before I was able to work out how to do it. Taking my previous Cool Solutions submission “Easy Running of Scripts at Boot and Shutdown” as a basis, here’s how I do it.

In a previous Cool Solutions submission I made reference to running scripts during shutdown and boot. This is something I do on all the machines I manage. I use such scripts to perform maintenance tasks and make sure various custom configurations are in place. Here’s how I do it.
