Mouse loses ability to copy and paste

Post by phil.e » 2019/02/11 15:59:56

I've got a user that just received a CentOS 7 upgrade (from 6.10). He's having an issue I've been asked to troubleshoot but I haven't been able to duplicate his problem.
When he first logs in, highlighting, selecting, copy/paste with his mouse works fine. After he's been working awhile, when he tries to highlight text, the highlighted text un-highlights as soon as he takes his finger off the left mouse button, and ctrl-A stops working even in graphical text editors. The only way to get it working again is to restart X.
The video card in the system is an NVIDIA Quadro K4200. NVidia-smi shows the NVIDIA 410.93 driver installed, but lsmod seems to show that it is still running the nouveau driver.
Any ideas?
Thanks

Is the system up to date via `yum update`?

The user sent me some more feedback:

"There seems to be a correlation between the errant clipboard/mouse behavior and when I fire up my VNC sessions. I do see a garbled display when VNC first posts the remote desktop - I didn't see this in CentOS 6"
