I am working with some Ubuntu systems to control some smart home things. I run Ubuntu on a industrial PC with an industrial touchscreen display. Everything was working fine. Since some time ago the touchscreen has stopped working after some time. I didn’t reboot the PC. I have the same problem on more than one Ubuntu system, so I think the problem is a software problem. I have looked in the logs and I always see this if the problem disappears:
Jul 27 15:02:28 byk-station /usr/lib/gdm3/gdm-x-session: source device 10: history size 6400 overflowing for touch 3088 Jul 27 15:02:50 byk-station /usr/lib/gdm3/gdm-x-session: message repeated 1585 times: [source device 10: history size 6400 overflowing for touch 3088]
This message comes often then. With this message the touchscreen stops working. Normally there helps a reboot, but I need to find a solution for the problem. I couldn’t add the whole syslog input here because it is too long.
