hardware-happy, part 2

9:25 am hardware

The things got more interesting when I changed original nv 5200 fx to ati 9800 pro. First, the wrapping effect immediately disappeared (does it mean ati and nv drivers read DDC dirrefently)? Second, the output is now _deadly_ slow. Scrolling (one line!) in xchat window is visible (takes a good fraction of second!). Tried both XAA and EXA acceleration. It seems something important is missing… DRI is also a mistery – in Xorg.0.log it is said to be enabled but glxinfo clams it is not.

Looking for some repository with xorg 7.3 for gutsy – may be it would help.

    X thinking DRI is available while userspace doesn’t usually means the wrong mesa lib is installed. On ubuntu, try making sure libgl1-mesa-dri is in place.

    I had the same sort of troubles with my ATI 9600.
    The mesa dri were not installed. I had to install the package libgl1-mesa-dri manually.

    Stemp, Jan, thanks, I’ll check for that package!

    That’s why I vowed years ago never to buy another ATI card :-)

    fraggle, AFAIK OS nv drivers suck, nouveau is very young (and not available in gutsy), so what would you use on powerpc?

    One thing worth trying is XAA with the XAANoOffscreenPixmaps option. It made a huge difference in window scrolling speed when I first tried enabling the Composite extension a while ago.

    Ubuntu carried a patch to X that enabled this option by default, but IIRC they dropped the patch recently (it caused some problems in other areas).

    Thanks Marius, I tried that as well – it did not change a thing :(

  8. Sergey Udaltsov Says:

    libgl1-mesa-dri was already installed :(

  9. Sergey Udaltsov Says:

    The problem is resolved! There was an old package xserver-xgl which spoiled the whole party!

    Thanks a lot lads for the food for thought…

    That would be the “hardy” repository :)
