Am I the only one struggling with Bullseye?? Setup: RPi 4, 8GB. Eviciv 7" touchscreen/case + VNC.

It seems like every time I turn around, something stops working.? Right now, it's screen blanking on the physical device.? For the time being, at least, while configuring and testing, I turn off screen blanking while I do most work via VNC.? The screen was staying on until, after a couple reboots, it started blanking after awhile.? Sure enough, the switch in RPi Configuration (GUI) was turned back 'on'. Turned it back off and went back to work.? Online research shows Bullseye has been plagued with related trouble for months.

Today, the "switch" is still off, but the screen is still blanking and the touchscreen is unresponsive.? Reboot and the physical device (display, touch UI, and BT keyboard) works fine until the screen blanks.? VNC continues working, regardless.? I'm confident that the physical device is stable because it's completely stable upon a new OS flash.? Yesterday, CubicSDR with an RSP2Pro suddenly (and again) broke while I was working on something completely unrelated and seemingly innocuous.?

I'm becoming convinced that Bullseye, components, and applications are not sufficiently stable for the appliance-like functionality that I'm seeking.? Not being new to Linux (25 years) or RPi "appliances", I'm really getting frustrated trying to get a basic set of BaP functions all configured and running stable.? Past experience suggests this isn't a hardware issue.? Even doing (semi-) regular SD card copies for system snapshots, I've had to start from scratch a couple times.? The SDR setup went kaput yesterday right after I started seeing "updates available" although I didn't install anything.? At this point, I'm going to have to turn off all updates and maybe even disconnect the network altogether.

Anyone else seeing similar?
