Bug ID: 476368 Summary: Output mapping of identical touchscreen devices doesn't remain after reboot Classification: Applications Product: systemsettings Version: 5.27.9 Platform: Archlinux OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: kcm_touchscreen Assignee: plasma-b...@kde.org Reporter: n.ruitenb...@gmail.com CC: nicolas.fe...@gmx.de Target Milestone: --- SUMMARY When two identical touchscreen devices are connected, it is not possible to configure their output mappings properly due to them having the exact same name. Looking at ~/.config/kcminputrc, the problem seems to be that when the first touch input is configured, the configuration for the second touch input simply overwrites the first entry due to the identical device names. Strangely enough, directly after the changes from the system settings are applied, everything seems fine. The problem occurs when the configuration is loaded after a reboot, where both touch inputs seem to be mapped to one display. It seems like extra information is needed to uniquely identify identical touch input devices. STEPS TO REPRODUCE 1. Have two identical touchscreen displays connected 2. Map each touch input to their corresponding display output (through trial and error because both devices have the same name) 3. Observe how the mappings seem to be correct 4. Reboot 5. Observe how the mappings are no longer correct OBSERVED RESULT Both touchscreen inputs are mapped to the same display output. EXPECTED RESULT The touchscreen inputs are mapped to their corresponding display output, as was the case before the reboot. -- You are receiving this mail because: You are watching all bug changes.
