I experience the same problem if I disable the touchpad using Xinput using this script:
#!/bin/sh for device in 'PS/2 Mouse' 'ImPS/2 Generic Wheel Mouse' 'AlpsPS/2 ALPS GlidePoint'; do /usr/bin/xinput set-prop "$device" 'Device Enabled' 0 done It's then enough to launch Inkscape and click on the empty workspace to have X crash. The stacktrace in Xorg log is the same (even the relative address offsets are identical). If I disable the touchpad then reenable it using this script, I can use Inkscape safely: #!/bin/sh for device in 'PS/2 Mouse' 'ImPS/2 Generic Wheel Mouse' 'AlpsPS/2 ALPS GlidePoint'; do /usr/bin/xinput set-prop "$device" 'Device Enabled' 1 done -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1081108 Title: Xorg crash after clicking on workspace in inkscape To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1081108/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
