Video playback fails due to missing xv support

[StefanF]

Binary package hint: linux-image

The problem occured first after I upgraded from Kubuntu 9.10 to 10.04.

I cannot play back Video anymore properly on my ATI Radeon Mobility M6. The XV driver is not available anymore..I found out that the problem is caused by KMS, which is now enabled by default. The graphic driver or chip does not support XV when KMS is enabled.

Adding the boot parameter "nomodeset" to /etc/default/grub fixed the problem.

Maybe the kernel should care the limitations of these affected old chipsets.

Sorry, I started the bug report tool from firefox, since I cannot do it from the grub prompt. And ubuntu-bug at the command line did not work properly.

My Kernel has release 2.6.32-21-generic. The lspci output for the graphic chip is:

01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY
        Subsystem: Compaq Computer Corporation Device 00b4
        Flags: bus master, stepping, 66MHz, medium devsel, latency 66, IRQ 11

        Capabilities: [58] AGP version 2.0

I do not have an xorg.conf (everything auto-detected fine as it should), but I also tried with such a file and played a lot with all the available options. But all that did not help until I disabled KMS.

I think we can close this. The affected computer got broken and my new computer is not affected.
