Weird Screen Effect After login

[microsoftWindus]

Hi all! I got a problem when I sometimes log into Linux Mint XFCE. This happens sometimes, sometimes it doesnt't. Maybe when I got low battery I dont know.

Here are pictures https://imgur.com/a/1Q0DnYR.

I posted this on Reddit, they said its maybe due to graphic driver. I have dual boot on this computer (Windows and Linux Mint) and with Windows I dont have this problem, maybe its cuz Windows have proprietary drivers while I installed free/non-proprietary drivers on Linux Mint.

Here is link to that Reddit post: https://www.reddit.com/r/linuxmint/comm ... mint_xfce/

I have Lenovo ThinkPad T470s. These are its specs:

• CPU: Intel i7-6600

• RAM: 12GB

• Graphics Card: HD Graphics 520

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.

Try this:
Update Manager - panel: View - Linux kernels
Install the latest kernel from the 4.18 series. Then reboot.

I have done it, no weird effects so far.

I shall report in few days to see if that worked!

Thanks!

[microsoftWindus]

I still got that effect even though I have installed new kernel. But that effect lasts like half a second, but again, I dont know if that is good or bad to have for computer, dont wanna damage some components.

I just want to point out, maybe this has problem with it. When I was installing Linux Mint, I didnt checked that box that said to install proprietary drivers for graphics, wifi and so on. So can that be problem, because I use free drivers instead of proprietary?

[Pjotr]

For your hardware, there aren't any proprietary drivers. So that's not an issue.

Try if it helps when you disable all visual effects in Xfce:

Thanks, I have done this, and I shall report after few days to see if it works!

Since my last reply I havent encounter that weird screen effect. When I type my login credentials (username, password), screen goes black for half a second or 1 second and then it goes normal. Still, better then weird screen effect. I thought that, maybe that screen effect that my computer is doing is bad for my graphics card.

Should I have Display Compositing in Windows Manager Tweaks -> Compositor on or off?

Thank You!
