I have two Kubuntu Edgy installations with exactly the same symptoms; "corrupted" memory, no user face in kdm_greet, chmodded /dev/null, bad device 166, missing X-11 fonts. Neither will boot normally, but both can run in 'recovery' mode, su to username and sudo startx. This has been killing me, and it's good to see I'm not the only one. The user reported last summer--was there any resolution?
Let me know what details of my setup will help, if any. -- login loop when finished installation of kubuntu-dsktop, using kdm insteda of gdm https://launchpad.net/bugs/53771 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
