ati radeon 7000 very slow frame rate

Asked by Thomas Brownlie

I am running Ubuntu 8.10... My PC is old-ish, it's a HP Compaq D330ST, Pentium 4 2.8ghz, with
1gb memory. Previously I was using the on-board graphics card - getting good resolution (1920x1080)
I installed a ATI RADEON 7000 VPU 64MB. Booted up Ubuntu but it did not recognise the card (run in "low graphics mode")
I then ran sudo dpkg-reconfigure xserver-xorg and rebooted my PC.
This worked - the system seemed to recognise the card (i had full 1920x1080, I could enable 3d desktop - so I was quite happy).
I then tried to watch an AVI file (either through VLC, Elisa, XMBC, Token) - it didn't matter what I used the frame rate was very, very, slow.
So slow that it was completely un-watchable (maybe 1 frame every 2 seconds?). It was so bad that the sound then came out of sync, and it appeared that frames were being dropped...
I shutdown. Took out the card, re-booted, redid "sudo dpkg-reconfigure xserver-xorg" and rebooted.
My pc is back to normal, working well - but naturally No 3d effects and no OpenGL.
Help! Suggestions? I tried to look up installing the binary drivers for ATI, but most posts seem to say "stick with what Ubuntu installs by default".

Please do not install a binary driver, the propietary ATI driver is not compatible that this model. If you install the binary driver you need forced uninstall, the OpenGl do not work with this driver.

Do you have install w32codecs of Medibuntu repository?

Yes I have installed the w32codecs.
Using the onboard graphics card I can watch AVI's (or just about anything for that matter!).
But when I install the ATI RADEON 7000 VPU & sudo dpkg-reconfigure xserver-xorg) then frame rate is very, very, very slow.
Are there any parameters that can be configured? is the problem that a 64mb graphics card is just not good enough?
i purchased the ati radeon 7000 vpu because it was on the ubuntu-supported-hardware-list... :(

I'm having almost the exact problem. Our rigs are almost identical also. I'm using the RV100 and the frame rate is slow but not quite as bad. I can watch movies, but they are a little jerky. I can't get 3d effects to work. Also, I get a much better framerate booting from LiveCD, but it bogs the system down.

Can you help with this problem?
