** Description changed: I downloaded this ISO of Raring Ringtail: http://cdimage.ubuntu.com/daily-live/20121129/raring-desktop-amd64.iso. I created a live non persistent USB key with Unetbootin. When booting my PC from this live USB key into a live session with the above image and also with Precise 12.10.1 I get a kernel oops, see attached image-1. If I boot my PC from the same live USB key, but instead of selecting "try Ubuntu" I select "Install Ubuntu" I get a messed up background with red spots and signs, see image-2. Even with the display all messed up I can carry out the installation, but when I boot my PC I get a red spotted and messed up backgroud, as soon as I login to my session I get a kernel oops again - see image-3. - If I install the proprietary ATI drivers (apt-get install fglrx), and reboot everything is fine, so I think that the problem is due to the video drivers (ATI radeon HD 6670). + If I install the proprietary ATI drivers (apt-get install fglrx), and reboot at least I can logon to my session but I get some crashes, so I think that the problem is due to the video drivers (ATI radeon HD 6670). I am attaching a lshw.txt file with my PC's hardware and the output of dmesg, lsusb and lspci. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1085187 Title: kernel oops during boot of Raring and Precise with live USB and after logon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1085187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
