*** This bug is a duplicate of bug 780923 *** https://bugs.launchpad.net/bugs/780923
I do see the same behaviour on my Computer. It has an Intel 4300 Graphics card. But I don't think this is a duplicate of bug # 780923, as there the screen shows partially the applications. Here, or at least on my screen, it is completely black, with backlight on, and I can see the mouse pointer and move it around on the screen, as if it was normaly working. But I can not see any window at all or interact with them. Switching to Console is possible(Ctrl+Alt+F1,F2,..) and back. Everytime I switch to the X-Server, an other line is written to the kernel.log, looking like this: Jul 5 21:55:39 nepotech kernel: [15774.021913] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id This bug is definately critical, as the X-Server doesn't work any more, and so all the normal programms used for everyday work have to be killed. ** Attachment added: "syslog" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/787811/+attachment/2193028/+files/syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787811 Title: [natty] Intel graphics X server freezes with "[drm:drm_mode_getfb] *ERROR* invalid framebuffer id" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/787811/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
