Impossible to use my secondary monitor in resolution 1366x768 (stripes on the screen)
With resolution : 1024x778, it has worked for the last year.

Hello,

Thank you for contacting us here on the forum.

Based on your description I would recommend testing different resolution modes.

Mainly, please add 1360x786 first and then 1368x768 and test it on them. In order to do it, please take a look at this article. (http://www.arunviswanathan.com/node/53) Article describes a general change for VGA.

In your case it should be probably:

DVI-I-1-1 (DVI- xxxx) and probably
gtf 1360 768 59.9, the rest accordingly.

Mode name should stay custom.

If you follow this link (https://gitlab.freedesktop.org/xorg/xserver/-/issues/889) you may read more about this issue.

Thank you for your actions, in case of any questions please let me know.

Best regards,
Jakub
