Hi everyone Just in case some one else encounters this problem... Last Friday, I installed the latest kernel update on my Linux Mint 20.2 MATE edition and rebooted the first time in a few weeks. After logging back in, I noticed that the Xorg process was using almost one core on my laptop. This wasn't the case when waiting at the login prompt (i.e., lightdm). Starting my file browser of choice, GTK version of double-command, (package: doublecmd-gtk), seemed to grab another core. Downgrading of Xorg or using an older kernel had no impact, unfortunately. When switching to XFCE4 for my session today, I didn't experience that high CPU load problem anymore. I also switched to the QT version of double-commander (package: doublecmd-qt). Not really solving the problem, more like side-stepping it, but at least I get can work done again, without my laptop fan going hard out all day... And I've used XFCE in the past. :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
