I use Ubuntu 20.04 with KNIME forwarded by X. I tried KNIME-full (with all extension) and normal KNIME without any addidional extensions and currently no anti virus. KNIME does not open its sample workflows: If I double click, the “Description” is shown but nothing else happens for minutes. If I try to import my own simple workflows, it takes minutes to import it I then I kill unfinished KNIME. If I try to create a new workflow, nothing happens after entering the workflow name. The logile /knime-workspace/.metadata/knime/knime.log is empty. ---

It is the RAM size configured in knime.ini. I wonder why KNIME-full with all extension is configured with only 2 gigs of RAM. I raised it to 10 gigs. ---

Hello @spider, glad you figured it out. I’m not aware of “KNIME-full with all extension” available somewhere. Where did you find it? Which version is it? Br, Ivan ---

I found it on [KNIME Product Downloads 2021-06 | KNIME](https://www.knime.com/knimecom-product-downloads-2021-06) in the section “KNIME Server Executor”: For Linux it currently refers to [https://download.knime.com/analytics-platform/linux/knime-full-latest44-linux.gtk.x86\_64.tar.gz](https://download.knime.com/analytics-platform/linux/knime-full-latest44-linux.gtk.x86_64.tar.gz) ---
