I get this as well on a Thinkpad X301 with a X4500HD card, but not on 100% of boots; on some boots things just work.
The symptoms are: you get a mouse on a black screen, but the cursor is blinking on the top left; after a couple of seconds I get some kernel messages from sda or sdb in the top left where the cursor was; pressing some keys results in weird chars being written at the top left too. Pressing Ctrl-Alt-F1 goes back to a clean tty1, and pressing Ctrl-Alt-F7 goes back to a clean gdm. If I try to login from that gdm, I see: Feb 25 09:12:35 bee kernel: [ 28.609195] [drm:drm_mode_getfb] *ERROR* invalid framebuffer id then gdm respawns the login screen, and I can login normally. ** Summary changed: - DRM Framebuffer crash - fail GDMThinkpads with Intel X4500HD + DRM Framebuffer crash; invalid framebuffer id; Thinkpads with Intel X4500HD -- DRM Framebuffer crash; invalid framebuffer id; Thinkpads with Intel X4500HD https://bugs.launchpad.net/bugs/523027 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
