    Login Screen is white. however desktop loads if password entered.

    Hi all,

    I have a weird issue on Lubuntu 20.04 LTS. when Lubuntu boots, I'm greeted with a plain white screen instead of the Login screen. However, If I type the password, The desktop environment loads without an issue and the computer works as its supposed to be.

    If I try to enter recovery mode and boot normally with limited display driver support, I can see a login screen.

    Can anything be done to fix the login screen?? I'm a novice user of Linux, kindly help.

    The system is more than 15 years old and its an AMD64 processor and has 2GB of RAM,

    Thanks.

    You should be able to boot in text mode, log in and then launch LXDE, but how I cannot tell. This may be something for you to explore.

    Re: Login Screen is white. however desktop loads if password entered.

    A correction should be made to HermanAB's post; Lubuntu uses LXQt and not LXDE (last eight releases not counting respins).

    The Lubuntu manual page (for 20.04 currently) can be found here - https://manual.lubuntu.me/lts/3/3.1/...iguration.html

    Note: When Lubuntu 22.10 is released in October; that manual link will contain the Lubuntu 22.04 LTS (where that page has a different section; Lubuntu 22.04's manual is currently the stablemanual). When this change occurs; I'll update https://discourse.lubuntu.me/t/manua...04-stable/3242

    You didn't say which kernel stack you're using (GA meaning 5.4 for 20.04, or HWE which is now 5.15 for 20.04.5) but I did experience some issues before in QA-testing on some video cards (i386 and amd64) with kernels >=5.3 (which you'll have) where the easiest option was to replace `sddm` with another DM, ie. use a different greeter. In this thread you'll find some reference to it, but switching to another DM maybe an easy workaround.
