[SOLVED] Black screen problem after login

Post by PoloLmint » Mon May 04, 2020 12:09 pm

Hi – I see several people reporting similar display problems, though usually they have different LM versions, desktops or propriety NVidia displays.

I have a new install of LM 19.3 xfce 32-bit on an old thinkpad X60 (Dual Core model: Intel T2400 bits: 32 with Intel Mobile 945GM/GMS 943/940GML Express Integrated Graphics . see attached inxi -Fxxxrz output)

For me LM normally boots fine to the login window, and once I enter the password, shows the xfce desktop no problems. This is usually the case, for login straight after a boot, or even after suspend.

However, sometimes, after a period of inactivity, usually after the laptop has either suspended, or if after a boot I don’t actually log in for some period (hours?)…. As expected, I get presented with the usual login window again, but after entering the password I just get a black screen showing only the white pointer. Ctrl-alt-del takes me back to the login screen, but I get the same black screen after I enter the password. I am forced to reboot to get a working display

I’ve tried it with 2 kernels (4.15.0-99-generic and 5.3.0-51) and get the same problem. And have experienced the same problem with a clean reinstall of lm 19.3 xfce

Solution 3 :

Ubuntu desktop icons not working

None of the above worked for you then you have to upgrade your Ubuntu for example from Ubuntu 16.04 to Ubuntu 18.04 or Ubuntu 18.04 to Ubuntu 20.04. Don’t worry your data will be safe.

First, open terminal by CTRL+ALT+F1

Now reboot your system and that’s is! Viola, You will have Unity back, and now you can get back to work, make some stunning design again with your Ubuntu laptop/desktop.

There are a few things that could be causing the issue with the icons on your Ubuntu desktop not working.

1. Corrupted icon cache: You can try rebuilding the icon cache by running the command “gsettings set org.gnome.desktop.interface icon-theme ‘Name_of_icon_theme’” in the terminal, replacing “Name_of_icon_theme” with the name of the icon theme you’re currently using.
2. Missing dependencies: Make sure that you have all the necessary dependencies installed for the icon theme you’re using. You can install them using the command “sudo apt-get install [dependency]”
3. Permission issues: Check the permissions on the icon files and folders. They should be set to 644 for files and 755 for directories.
4. Conflicting theme: If you have installed multiple icon themes, it may be causing conflicts. Try uninstalling all but one icon theme to see if that resolves the issue.

If none of the above solutions work, you can try reinstalling the desktop environment or reinstalling ubuntu.

If the icons on your Ubuntu 22.04 desktop are not showing, there are a few things you can try to troubleshoot the issue:

4. Check for Gnome-shell extensions: Some gnome-shell extensions can cause the icons not to show. Try disabling or uninstalling the extensions and see if that fixes the issue.
5. Delete icon cache files: Sometimes the icon cache files may get corrupted, try deleting the icon cache files located in ~/.cache/icon-cache and ~/.local/share/gvfs-metadata

If none of the above solutions work, you can try reinstalling the Ubuntu desktop environment by running

sudo apt-get install --reinstall ubuntu-desktop

1. Check for updates: Make sure that you have the latest updates installed for your system. You can check for updates by running the command in the terminal.
