So I guess you have three bugs: 1. Xorg crashed (this bug) 2. The webcam generates bad jpeg images 3. python-launchpadlib wasn't installed
I'd like to focus this bug report only to the first issue. Bug reports for the second and third would be worth filing, but I'm not sure what to file the webcam jpeg issue against. ** Changed in: xorg-server (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1168250 Title: [Nexus7] Xorg crashed with SIGSEGV in __memcpy_ssse3_rep (from sna_video_overlay_set_port_attribute(): guvcview crashed when changing resolution of a picture Status in “xorg-server” package in Ubuntu: Confirmed Bug description: I was testing Lubuntu Nexus 7 session in a persistent live system. First I noticed that it works with the built in camera :-) Then I noticed that the default setting (to save a jpeg picture) creates a bad picture file, that cannot be read by gpicview. Work- around: save a png picture. I suggest that the default setting is changed until the jpeg bug is fixed. Finally a changed the resolution to 1280x720 which worked. But when I changed back to the default 640x480, the program crashed the system and sent me back to the log in screen. #7 0xb774543e in FatalError (f=f@entry=0xb776d3c4 "Caught signal %d (%s).
