I have a DELL XPS 13 9340 (New Version) and I have installed Ubuntu 22.04. One week ago, I notice some screen flickering (horizontal colored lines appear when moving the mouse).

I have reformated the hard drive and installed a dual boot Windows & Ubuntu (in order to check the issue with Windows). The problem disappears. But today fllickering appears again when using Ubuntu. I have no problem with Windows. If I boot my computer with the Ubuntu USB key, the problem disappears.

I suspect that an update version of Ubuntu is installed and produces this flickering.

Many thanks for your help.

I had the same problem on my Dell XPS 13 9340 (2024) : screen flickering when mouse is moved. It happened just after a kernel upgrade (from 6.5.0 to 6.8.0).

I downgraded the kernel and it fixed the problem.

Here how I did it:

Check image version : I had 6.8 (latest) and 6.5

dpkg -l | grep linux-image

Remove latest (image plus headers)

sudo apt purge linux-image-6.8.0-40-generic
sudo apt purge linux-headers-6.8.0-40-generic
reboot

Hope this helps,

Regards,

E.

Had the same issue on XPS 13 with Ubuntu 24.04.

The issue is fixed by upgrading to the oem kernel:

sudo apt install linux-oem-24.04

... or you need to wait until the issue is planned to be fixed in "6.8.0-45.45 or later".
