boot - How can I access my desktop from root shell prompt in recovery menu?



I updated graphics drivers today, which unfortunately causes a black screen at login. I want to access my desktop so I can copy certain files off the laptop while I figure out a fix, but I'm unable to open a terminal at login using Ctrl+Alt+F1.



Booting in recovery mode, I can select the "root" option to drop to a root shell prompt. From here, I can login to my user account through:



su --login myuser




...where I get a message that says "No directory, logging in with HOME=/". However, I cannot change directories to my Desktop, which should be located at /home/myuser/Desktop/. I can cd into the home directory, but it appears like there's nothing in it. Any thoughts on how to access my Desktop through the root shell?



As I know, when you boot into recovery mode, the home partition will not mount automatically.



First locate your home partition using commands like: lsblk or fdisk -l or even by having a look at /etc/fstab:



# grep '/home' /etc/fstab | grep ext



Then mount that partition at /home (in my case sda2 is my home partition).



# mount /dev/sda2 /home


And copy your file to your desired path, device.



Remember that you may need to remount or mount your partitions with rw option.
