Hi Older iMac, recently installed Debian 11. Having system freezes even when running light weight environment like fvwm. Starts with slow video, progresses over a few minutes to complete freeze. Can't even shift to a different console with ctrl-F_. Nothing in top (when it starts) to suggest excessive memory or cpu usage. Tried to install nvidia drivers, but apparently not available for my GPU in Debian 11. Output from lscpu and nvdia-detect in attached file. I would be grateful for any suggestions. Thanks Bob Crochelt
