I think that Xsession terminated before 10 seconds is other problem. Here , gdm start normally and I can use the desktop. the only problem is that something at undergroud was crashed.
I was thinking and I see ,maybe, the origin the bug is that klauncher dont work well with applications removed. In my case , there is one icon at autostarter for ktorrent, and to make a "flesh" install of kde4 I removed all old kde and the ktorrent as depedend was removed too. then I think that klauncher was not able survivor to "command not found" -- klauncher crashed with SIGSEGV in __kernel_vsyscall() https://bugs.launchpad.net/bugs/141418 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
