I have two systems on my machine. One is Ubuntu and the other one is Linux from scratch (LFS) which I built it my self.

Ubuntu has X window system installed but LFS has no windowing system whatsoever.

I chroot from LFS (/dev/sda3) to Ubuntu (/dev/sda1) root partition with following commands:

mkdir /mnt/sda1
mount -v              /dev/sda1    /mnt/sda1
mount -v --bind       /dev         /mnt/sda1/dev
mount -vt devpts      devpts       /mnt/sda1/dev/pts -o gid=5,mode=620
mount -vt proc        proc         /mnt/sda1/proc
mount -vt sysfs       sysfs        /mnt/sda1/sys
mount -vt tmpfs       tmpfs        /mnt/sda1/run
chroot /dev/sda1

Then after chrooting, I ran xinit. X window system started but apparently without detecting mouse.

Currently I'm stuck in X window system and I cannot do anything. When I press ctrl+alt+F1 to F6 or ctrl+alt+backspace nothing happens. To complicate matters further, before I chroot, I was compiling something on another console tty and I don't want to lose that compilation progress with pushing hardware restart button.

Is there a way out of this situation.

    Can you post the X server log ? – Johan Boulé Dec 29 '16 at 19:34
  • I don't have access to that system any more, I wish I could see the log now – user3405291 Jan 5 '17 at 16:12

Some people have reported you need to bind-mount udev too.

  • Oh, right, i always forget this site has several kind of posts.. should have made it a comment I guess. – Johan Boulé Dec 11 '16 at 0:23
  • Do you know where udev is located on root file-system? – user3405291 Dec 29 '16 at 16:54
  • Sorry, it's actually /dev, which you already have bind-mounted. I didn't see that. I guess I should just remove this answer. – Johan Boulé Dec 29 '16 at 19:29
