I fixed this problem by booting with a grub 2 disk. I changed the grub 2 command line to vga=normal. I removed quiet and splash to skip the unviewable boot splash. This allows the garbled characters to be seen.
I have an hvr-1600 card in the box so I guess it is still subject to the boot hangup bug. Added the vmalloc=256M to the boot params and that fixes the hang up. Additionally I made an Xorg.conf to run the vesa driver and used that to get fully booted. I fiddled with reinstalling the nvidia driver. I think the previous steps actually render using the vesa driver superfluous. All this must be done from the command line by selecting single user from the options presented when booting via grub 2 cdrom. So I think the problem must be the boot splash is set to some video mode the nvidia card does not like. Plus I had one more old bug that hung up the boot process. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/768145 Title: Plymouth boot logo corrupted - shows white vertical stripes -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
