Experiencing screen tearing, on a fresh install. Tried a bunch of stuff, anybody got any idea?

Picom should be running by default if you’re on a supported release. Please confirm as that should solve most issues. If that’s good, use lspci -nnk give us the results of the section related to your video card. And the Lubuntu release you’re on.

I’m on the stable 24.04 release, and this is the output of the above mentioned command:

00:02.0 VGA compatible controller [0300]: Intel Corporation UHD Graphics 620 [8086:5917] (rev 07)
        Subsystem: Lenovo UHD Graphics 620 [17aa:506c]
        Kernel driver in use: i915
        Kernel modules: i915

You answered the latter part of my response, but not the first.

Apologies, but how do I check if it is running?

Countless ways. pgrep picom, check in qps, see if it shows “Running” in the LXQt Modules section in Session Settings, etc.

Running the pgrep picom command shows no output, and there is no picom in LXQt Modules section. Running picom in a terminal only gives an suggestion to install it via apt.

I installed picom, it got added to the autorun list. No more tearing. TY for the help.

For picom to not be there, you must have chosen the minimal install. Weirdly, picom-conf ‘is’ installed.

Yup, I used the minimal install. I did encountered an instance where I was watching YouTube and copying over some files from an external HDD and the whole system froze with audio repeating in a loop.
