I posted https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1921066 yesterday which was marked as a duplicate of this one, which I agree with.
Please advise which logs are appropriate. I can boot into one of the "bad" kernels and collect standard logs etc. while it is running but *before* I try touching the screen with the stylus. This would give standard info but not necessarily pinpoint the issue. What I would really like to know is this: if I replicate the problem (i.e. freeze the OS), will this write appropriate diagnostic info to some log file which is then still available after a hard reboot? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1919342 Title: Stylus and touchscreen not working in kernel 5.8.0-45 Status in linux package in Ubuntu: Confirmed Bug description: After an update from 16th March 2021, the stylus for Acer Spin 5 stopped working and wasn't charging.
