Public bug reported: Quite regularly the graphics driver does not load on boot and I am stuck with a purple screen. Grub shows fine but when I select Ubuntu I get the purple screen. On a succesfull boot the purple screen disappears and I see the runscripts (I removed 'quiet splash' from the boot options'), but sometimes the screen merely flickers and stays purple. However the system is still responsive, I can use Alt+SysReq+REISUB to reboot and I can even ssh to my machine.
My machine is a samsung-305u1 (with a AMD Fusion E-350) and I use the open source drivers. According to http://ubuntuforums.org/showthread.php?t=2012657 the problem can also occur on nvidia machines, and by typing the following commands in the grub commandline the system boots fine: test continue videoinfo normal Setting 'nomodeset' also seems to work but this boots my machine to unity 2d. The problem seems to occur quite randomly, but by doing the next steps I can reproduce the problem 4 out of 5 times: 1. Boot normally 2. Connect external monitor with larger resolution 3. Close the lid of the laptop ( i guess this turns of the laptop screen) 4. Shutdown 5. Remove the external monitor 6. open the lid and power on Because I can ssh into the machine i can provide error logs, but I don't know which ones to provide, so someone please point me in the right direction... ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069353 Title: graphics driver does not load on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1069353/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
