I've had this papercut for a while now, it's time it was fixed.
When I boot up Ubuntu, choosing "Ubuntu...generic" from the grub screen, Ubuntu fails to load. It just sits at the driver/module loading screen. What seems to be the most significant line in this output is "xhost: unable to open display"
If I choose "Ubuntu...(recovery mode)" from grub then it loads OK.
I don't get why this is.
Out of interest I tried enabling boot error logging with
but I'm not seeing anything in that file.
I've had this problem since fresh install of 11.10.
$ sudo lshw -C display *-display description: VGA compatible controller product: GF104 [GeForce GTX 460] vendor: nVidia Corporation physical id: 0 bus info: pci@0000:03:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller bus_master cap_list rom configuration: driver=nvidia latency=0 resources: irq:16 memory:f6000000-f7ffffff memory:e0000000-e7ffffff memory:ec000000-efffffff ioport:bf00(size=128) memory:e8000000-e807ffff
*Edit: I thought I'd fixed the problem by disabling BOINC, but this only worked for the first reboot. Reboots after, and subsequent, failed to make it to gnome login.
Things I've done to try and fix the problem:
- Remove /etc/X11/xorg.conf
- Disable BOINC
- sudo mkdir /etc/exports.d
My /var/log/boot.log now looks like this:
fsck from util-linux 2.19.1 /dev/sdb1: clean, 648476/3121152 files, 3926355/12471552 blocks (check in 5 mounts) Skipping profile in /etc/apparmor.d/disable: usr.bin.firefox * Starting AppArmor profiles [80G [74G[ OK ] * Exporting directories for NFS kernel daemon... [80G [74G[ OK ]
Any help would be appreciated.
