Ubuntu 11.04 vs. Intel 865G

Hm, it looks like this post has stuck in my drafts for some years now...

Compositing produces a considerable amount of flicker and the display is obstructed by random image parts. dmesg is also full of page flip errors.

Solution:

cat >~/.drirc <<EOF <driconf> <device screen="0" driver="dri2"> <application name="Default"> <option name="vblank_mode" value="0" /> </application> </device> </driconf> EOF service gdm restart

Also needed to append the following to the kernel command line, or else I got a lot of squashfs block read errors:
acpi=off noapic ide=nodma all_generic_ide pci=nommconf

Watching 3D TV for free using mplayer

Antenna Hungaria is testing 3D broadcast over the air for the time of the Summer Olympics and the UEFA European Football Championship. In idle time, they are scheduling lovely programs of documentary, nature and the like. Anyway, I wanted to see how easy it is to view such side-by-side content in 2D while preserving maximal quality. As anticipated, mplayer works like a charm, see the uploaded script: watch_3d_dvb.sh
