I’ve recently upgraded successfully from Intrepid Ibex (8.10) onto Jaunty Jackalope (9.04) – Err – yes – I’m talking about Ubuntu, to be more precise, about Kubunu x86_64. The upgrade was quite a success, and actually the first one, after which my system was still usable, although I heavily screwed around in it.
Here are my first impressions, and a few must have mods or settings.
- 1) VDPAU
I’m utterly pleased to announce, VDPAU and compositing window manager like Metacity (Gnome), KWin (KDE/Plasma) and Compiz are working now. Also TwinView is working for me. I’m using this repo:
# nvidia deb http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu jaunty main deb-src http://ppa.launchpad.net/ubuntu-x-swat/x-updates/ubuntu jaunty main
Nvidia’s default driver is 180.44 at the moment, and has still a few major bugs in it. In order to use the repository above, just add these lines above into your /etc/apr/sources.list and perform a aptitude update. Then go into KDE Start menu –> System –> Hardware Drivers. And remove the current Nvidia driver (if you are using one at all). Reboot, and add now the new driver with Hardware Drivers again.
It’s Nvidia version 180.53 at the moment and still has some flaws. I’m using this line to test the VDPAU output with a AVCHD sample from my Canon camcorder HF100:
/usr/bin/mplayer -vo vdpau -vc ffh264vdpau -fps 50 my-sample-file-here.mts
Pressing madly “f” for fullscreen while playing a clip, mplayer crashes after a while. The console gives me this output:
[vdpau] Error when calling vdp_presentation_queue_block_until_surface_idle: A catch-all error, used when no other error code applies. [vdpau] Error when calling vdp_output_surface_destroy: An invalid handle value was provided.
Restarting KDE makes mplayer play again for a while. So I’m quite satisfied with it now. Without any special tweak mplayer is running almost with no CPU utilization. The new VDPAU version from Nvidia does real magic here. Guys, just great – Thank you
To use Ctrl+Alt+Backspace for restarting your X session (KDE) you need to turn on the
DontZapoption. By default this combo is now disabled Your ServerFlags section in
xorg.confshould look like this:
Section "ServerFlags" Option "Xinerama" "0" Option "DontZap" "false" EndSection
There’s no GUI available at the moment. You have to edit your
- 2) Emerald
Don’t know why, but Emerald and Compiz didn’t work for me properly. I had always distortions somewhere on the screen, or the decoration didn’t show up at all sometimes. Now I can use this very nice window decoration.
aptitude install emerald
and download a few fancy themes.
