Only background and mouse pointer after login Ubuntu 18.04

(Update Dec 8th, 2021: I have found the root cause. Thank you all the same. I am posting the root cause.)

Recently I work with a Ubuntu 18.04. One day, after login desktop, there are only background and mouse pointer.

But I still can SSH to the system. I create a new account by SSH and I can log in desktop with that new account.

I log in to the bad original account by SSH and do the following:

mv .cache .cache.old
mv .config .config.old
mv .local .local.old
sudo reboot

After this, the problem remains, i.e., I can log in to my new account to the desktop, but if I log in to my old account, there are only background and mouse pointer.

How to bring my old desktop account back?

By the way, my Ubuntu 18.04 is a VM in VMWare. I installed the default desktop environment and it works well. Yesterday I installed a Robot Operation System (ROS) in it, and installed Shadowsocks, I tried to run a self-written script to start Shadowsocks client at startup by adding service approach and @reboot in crontab approach but failed, but I can manually make proxy works by Privoxy and Shadowsocks, and I set proxy of my desktop environment. But the problem occured at next reboot.

@guiverc, it is not intentionally clean. I installed the default desktop environment of Ubuntu 18.04 and it works before. But yesterday, after I installed the Robot Operation System (ROS) and shadowsocks client, and tried to start self-writing shadowsocks client startup script with failure by service approach and later by @ reboot in crontab approach, and set desktop proxy manually to use Privoxy and shadowsocks, it becomes clean at later reboot.

I finally found the root cause, an incorrect config in my .bashrc file. It is a long story. I write them below:

This Ubuntu is a VM in VMWare Windows 10. And simultaneously I am trying WSL GUI. In .bashrc of my WSL account, I added:

export DISPLAY=host_ip:0.0

With an X11 server (VcXsrv) on host, I can run GUI programs on WSL. After this success, I tried this on bash session to my VM Ubuntu in host SecureCRT, and it is also a success.

Then I wrongly added the same export DISPLAY=xxx:0.0 configuration in .bashrc of my VM Ubuntu account. On the new login after this, I cannot use the GUI of my VM Ubuntu and without knowing why. And I asked here.

It is a per-user-account problem. But it cannot be solved by deleting ~/.cache ~/.config ~/.local because the root cause is in .bashrc. I found the root cause by accident.

That is the full story. Sorry for the trouble. Thank you all!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
