Hi, I have the same problem on IBM Thinkpad T42p. The Laptop has both, Trackpoint and Touchpad. In xorg.conf the synaptics driver is pointed to the "event" device of the touchpad. However no mouse (trackpoint, touchpad and even USB mouse) works with xserver-xorg-input-synaptics_0.14.7~git20070706-1ubuntu4_i386.deb. As a workaround I installed XOrg from gutsy with aptitude -t gutsy install xserver-xorg-core xserver-xorg-input-all xserver-xorg-input-elographics xserver-xorg-input-evdev xserver-xorg-input-kbd xserver-xorg-input-mouse xserver-xorg-input-synaptics xserver-xorg-input-wacom xserver-xorg-video-all xserver-xorg-video-amd xserver-xorg-video-apm xserver-xorg-video-ark xserver-xorg-video-ati xserver-xorg-video-chips xserver-xorg-video-cirrus xserver-xorg-video-cyrix xserver-xorg-video-dummy xserver-xorg-video-fbdev xserver-xorg-video-glint xserver-xorg-video-i128 xserver-xorg-video-i740 xserver-xorg-video-i810 xserver-xorg-video-imstt xserver-xorg-video-intel xserver-xorg-video-mga xserver-xorg-video-neomagic xserver-xorg-video-newport xserver-xorg-video-nsc xserver-xorg-video-nv xserver-xorg-video-rendition xserver-xorg-video-s3 xserver-xorg-video-s3virge xserver-xorg-video-savage xserver-xorg-video-siliconmotion xserver-xorg-video-sis xserver-xorg-video-sisusb xserver-xorg-video-tdfx xserver-xorg-video-tga xserver-xorg-video-trident xserver-xorg-video-tseng xserver-xorg-video-v4l xserver-xorg-video-vesa xserver-xorg-video-vga xserver-xorg-video-via xserver-xorg-video-vmware xserver-xorg-video-voodoo fglrx-control xorg xorg-driver-fglrx xserver-xorg
After that, everythings works. The only thing that changed was the XOrg version, kernel and hardware did not change in any way. I reproduced the error twice by upgrading and downgrading XOrg. ** Attachment added: "xorg.conf" http://launchpadlibrarian.net/14202358/xorg.conf -- Touchpad not working after kubuntu 8.04 installation https://bugs.launchpad.net/bugs/226433 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
