I had reinstalled ubuntu 20.04 and all was working well with the touchscreen. I installed all updates one by one and it was working too. Changed on prime between intel mode, nvidia on demand and nvidia performance mode too.
I was able to reproduce the bug when I activated "fractional scaling" and set it to 150% on gnome settings. Since this the touchscreen doesn't work anymore on my ubuntu session. I had disabled "fractional scaling" and set to 200% like just after the installation but it doesn't work anymore. Tried again with nvidia and intel mode with the same result. Can it be a bug related to gnome ? ** Attachment added: "fractional scaling.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886912/+attachment/5391477/+files/fractional%20scaling.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886912 Title: DELL M3800 Touchscreen not working after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1886912/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
