Kubuntu 9.04 3D driver in Acer Aspire One AO751h

[Gavagai80]

I've followed all of the instructions in the guide, and that did give me the full resolution (1366x768), but it doesn't give me 3D acceleration. I attempted the recommendation described in http://ubuntuforums.org/showpost.php...98&postcount=9 for that, as the guide suggested. But, there isn't an

Option "DRI" "off"

line in the xorg.conf to replace. I tried adding

Option "DRI" "on"

in what seemed a likely spot, but this xorg.conf doesn't help (google earth, just to use an example program, still reports it's in software emulation mode and runs slow):

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)

# here are ignored.

Can someone suggest what xorg.conf I should try?

Tried

from a suggestion in another document. That doesn't help.

Added myself to the video group as suggested by https://wiki.ubuntu.com/HardwareSupp...eoCardsPoulsbo . That doesn't help.

Checking /var/log/Xorg.0.log, I find a line saying "Poulsbo Xpsb driver not available. XVideo and 3D acceleration will not work."

Is xpsb different from the regular psb that enables the full resolution?

Edit for update: yeah, found xpsb-glx in synaptic isn't installed. I'll try installing that.

Later update: okay, that "worked" but crashes every 10 seconds or so in 3D programs.

I have an Acer Aspire One and so far it has worked great. I have used it for easypeasy, ubuntu and puppylinux from a usb drive and have not had major problems. is it kubuntu?

[Gavagai80]

Have you tried anything 3D on those distros, like neverputt or google earth, and found them fast? Regular stuff works fine. Enabling 3D makes it extremely unstable.

I've tried ubuntu 9.04, netbook remix 9.10, opensuse 11.1, kuki, linux4one and fedora 11 -- so far, kubuntu is the least broken. I've gone back to the 2D (but not VESA) driver, I guess I can live with that.
