Hello,

Following my comment #217:
I had no problem since this comment until tonight.
I was looking a video from http://www.youtube.com/NASATelevision and found the video very jerky, however it was already jerky before my upgrade to X 1.8.2 and the 2.12 intel video driver from Brian package. I think this jerky effect became very pronounced since I upgraded from 8.04 to
10.04.
Hence, I wanted to know if hardware acceleration was working or not. Looking at ubuntu forum I found I could use the command: glxinfo | grep "direct rendering" to have the answer.
So I typed the glxinfo command above and the result was (all three in a row):
1 - the GUI disappeared, replaced by many error text lines
2 - a black screen (cursor at upper left corner)
3 - the GUI reappeared but offering me to logon ...

By looking at /var/log/Xorg.0.log.old, I can see a segmentation fault occured (see attached file).
Can't I use the "glxinfo" command ?
What can I do to:
- not have this error
- have a video of better quality

Best Regards,
Jean-Marie
