Enabling monitor power save mode on Mandriva 2009.0

I couldn’t find how to enable monitor power save mode in Mandriva 2009.0 KDE — the screen saver just kept going and going without ever turning the monitor off.

It’s really quite easy — it’s just that the setting has moved from screensaver options to monitor options:

Just go to “Configure Your Desktop” -> Display -> Power Control

(Thanks to a forum post on 0x61.com for leading me toward the right idea!)

K3B: Restorin’ them data files

I had burned a backup of all our word processor files onto a CD-R, and armed with how to get the CD drive to show up in the Windows 95 virtualbox I popped that backup CD in to restore the data files onto the virtual hard disk.

I could pull up a directory listing for the backup CD, but only the first (oldest) backup folder appeared.  Oops, maybe Windows 95 didn’t support multisession CDs out of the box?  Mandriva can see the word processor data file backup directory on the CD, but Windows 95 can’t.

I had the idea, what if I could “burn” just the data files I wanted to their own .iso image file and then mount that in virtualbox to present to Windows 95 as the CD-ROM to copy from?

In the Mandriva application launcher menu search box I typed burn and found a program called k3b.  Here’s how I used the options to get the result I was looking for:

  1. I copied the files to the hard drive (in retrospect I don’t think this was necessary)
  2. I dragged the folder of backup data onto the what-to-burn area on k3b’s main window.
  3. I clicked the Burn button.
  4. On the Writing tab, I chose Only create image:
  5. On the Image tab I chose where the .iso image file should be created (or rather, took note of the default):
  6. After clicking Start and creating the .iso image, I was able to set that up as a CD-ROM image in virtualbox, mount that image, and copy the files into my virtual Windows 95 box.  Woohoo!

Upgrading to KDE 4

A Little Blue Icon

Probably several weeks ago now, I was using my Mandriva Linux PC at home and instead of the red “critical updates are available” icon that sometimes appears in the system tray, a blue icon that seemed to say “this isn’t urgent” appeared.  What was available was a distribution upgrade.  It was offering to upgrade my whole installation from Mandriva 2008 (2008 Spring, I think?) to 2009.0.  Hmm!

Last week I decided to go for it.  I let it run overnight, and with only one hiccup (at around 4am I checked the progress and it looked like at about 90% complete my broadband connection had dropped — it was discouraged and I had to encourage it to try again :)  it completed by morning.

KDE 3?

When I booted up the new system, I saw some UI changes… but I noticed that it was using KDE 3.5.  One of the reasons I was interested in the upgrade was to see how KDE 4 looked and behaved… I was puzzled.

The Mandriva 2009.0 Tour pointed me to the release notes, which clarified it all.  It said:

There is also a brand-new upgrade method available: graphical in-line upgrade…Please note this upgrade method (or text-based method) will not change your default desktop. If you were using KDE 3, KDE4 will not be installed automatically. You will need to install it after the upgrading, by installing task-kde4 meta package.

Still KDE 3?

I happily ran urpmi task-kde4 (It’s great to be able to specify at such a high level what to install; and I also enjoy seeing what the dependencies are that are pulled in to make it happen).  But when I logged out and back in… still KDE 3.5.  Hmm!


One more search was needed, and I found this:

Now…after all the KDE 4 packages will be installed, you will be able to log in KDE 4.1 by selecting KDE4 in the session menu of the display manager ( KDM, GDM, … ).

(from a post on Linux-Wizard, pointed to by a forum post on mandrivausers.org.)

Ah.  I logged out and at the login screen, clicked on that icon I had forgotten about, that lets you choose the display manager.  “KDE” was the default, but now there was a KDE4 option.  I picked that and… now I’m up and running in KDE 4.

Thanks for all the great work, Mandriva team!!
