reate a file /etc/apt/preferences and add
Package: xserver-xorg-video-psb
Pin: version 0.15.0-0ubuntu1~804um4
Pin-Priority: 1000
Save the file and run apt-get update & apt-get upgrade then it will downgrade. But i still have a strange behaviour in X, sometimes windows are closing unexpectedly…
I think you’ve still got mismatched driver/binary bits. The working version from the ubuntu-mobile PPA is 0.16.0+repack-0ubuntu1~804um6. You might have to download and install it manually:
brian@pol:~$ wget http://ppa.launchpad.net/ubuntu-mobile/ubuntu/pool/main/x/xserver-xorg-video-psb/xserver-xorg-video-psb_0.16.0+repack-0ubuntu1~804um6_lpia.deb
brian@pol:~$ sudo dpkg -r xserver-xorg-video-psb
brian@pol:~$ sudo dpkg -i xserver-xorg-video-psb_0.16.0+repack-0ubuntu1~804um6_lpia.deb
I’m not familiar with the /etc/apt/preferences trick you use – what I’ve been doing is going into synaptic, selecting that package and hitting “Lock version.” Stops the automatic updates from bugging me about the new release.
I can also confirm that the 0.20.0 version breaks 3D – probably a mismatch with psb_dri.so. Still waiting for Intel to release this stuff for real…
