Just a little precision. If I open my "rom1" session where I have enabled and disabled the fractional scaling, then I close it and open the "test" session my touchscreen is not working.
If I reboot the computer and open "test" session only my touchscreen is working. It seems that open my "rom1" session first block something on the system that affect all users that log after. If I don't open this session after a reboot I have no problem on other users. Please find the result of this command on my test session with working touchscreen: journalctl -b0 > journal_working_touchscreen.txt ** Attachment added: "journal_working_touchscreen.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-libinput/+bug/1886912/+attachment/5392242/+files/journal_working_touchscreen.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/1886912 Title: DELL M3800 Touchscreen not working after login with fractional scaling.
