Need DRI2 on R600 cards

Binary package hint: compiz

I am test intrepid 64bit from the 20080829 live cd. with radeon hd 3650 using the radeon driver.

it logs in to gnome fine, but if i start compiz i get a white screen. from a VT i can get back to metacity.

compiz does seem to be working (just it displays the desktop and any open windows as white) I can do Super+E and see the zoom out effect. see attached screen shot.

Confirm with linux 2.6.27-3 (32bits) and Intel Corporation Mobile 945GM. It was working on alpha4. I did a dist upgrade in one time and it doesn't work now (white screen, with slow but visible cube rotating effect). I use ALT-F2 to restore metacity.

I have notice a strange behavior : compiz doesn't use direct rendering on my system whereas it's capable of. Compiz doesn't detect texture_from_pixmap at is usualy do.

fabien@fabien-laptop:~$ compiz --replace > /tmp/compiz.log
/usr/bin/compiz.real (video) - Warn: No 8 bit GLX pixmap format, disabling YV12 image format

This only occurs for me when I use SubSection "Display" with virtual directive in "Screen" Session (to get dual head). Commenting this SubSection make compiz work correctly again.

compiz is now blacklisted (or not whitelisted) on the card.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Could you try to reproduce the same with Ubuntu 9.04? Thanks in advance.

if i boot with the 20090131 live cd, it does not start compiz.

if i try to start compiz from the command line i get the following.

ubuntu@ubuntu:~$ compiz --replace

i guess you could close this bug, as it is effectively a wishlist for 3d acceleration on r600 cards with the opensource radeon driver.

Thanks for your bug report. The symptoms provided indicate this is a problem with your video drivers and is being reassigned to the xorg package. For more information on problems with visual effects and video drivers see http://wiki.ubuntu.com/VisualEffects.

Lucid uses kernel modesetting for radeon, which implies DRI2.
